detailed description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

The Internet facilitates users to obtain and download various files, many of which involve user privacy or security issues, such as confidential work documents and private seed files. Users need to encrypt files during download and storage. Currently, users manually encrypt files after downloading them.

However, if the user manually encrypts the file after downloading the file, the user's workload is large, and it is easy to forget, the efficiency of file download is relatively low, and the user can only encrypt the downloaded file, and cannot Files are encrypted or hidden, which is likely to cause files to be peeped by others during the download process, thus threatening user privacy.

The disclosure determines whether the download features include preset features that match the private file by acquiring the download features of the files to be downloaded, and downloads the files to be downloaded to the private space when it is determined that the download features include the preset features, wherein, privacy The space is the space for storing private files. By identifying the download feature of the file to be downloaded and detecting whether the download feature includes a preset feature, it is possible to directly determine whether the file to be downloaded is a private file and whether encryption processing is required from the source, thereby improving the encryption efficiency, and When the download feature includes the preset feature, you can directly download the file to be downloaded to the private space, so that the entire download process of the file to be downloaded is encrypted for privacy, preventing the file to be downloaded from being stolen by others during the download process, and improving security for file downloads.

Fig. 1 is a flowchart of a file downloading method according to an exemplary embodiment 1. As shown in Fig. 1, the method includes the following steps S101-S103:

In step S101, the download feature corresponding to the file to be downloaded is obtained.

In step S102, it is determined whether the downloading features include preset features matching the private file.

In step S103, when it is determined that the download feature includes the preset feature, the file to be downloaded is downloaded to the private space, where the private space is a space for storing private files.

For example, the private space is a space with permission verification or hidden attributes, and files placed in the private space are invisible to users without permission. The private space can be a folder manually set by the user, or a folder created or defaulted by the downloader. And the permission verification method of the private space may include but not limited to at least one of the following encryption methods: digital encryption, symbol encryption, text encryption, letter encryption, graphic encryption, fingerprint encryption, etc.; or the private space can also be set as a hidden file in the form of clips.

In order to prevent files from being peeped by others during the download process, the user privacy is threatened. Therefore, the file to be downloaded needs to be protected during the downloading process of the file to be downloaded. To protect the downloaded file during the download process, it is necessary to judge the download feature of the file to be downloaded. After judging from the download feature that the corresponding file to be downloaded is a file that needs to be protected, it can be downloaded. During the process, the files to be downloaded are protected.

In the present disclosure, after obtaining the download feature of the file to be downloaded, it is determined whether the download feature includes the preset feature matching the private file, and when it is determined that the download feature includes the preset feature, it is determined that the corresponding file to be downloaded needs to be downloaded protection during the process of downloading, then directly download the file to be downloaded to the private space, wherein, it can be determined whether the file to be downloaded Saving to the private space does not require the user to decide whether to store the file to be downloaded in the private space, which effectively improves the efficiency of file downloading and improves user experience.

Since the private space is a space with permission verification or hidden attributes, and the private space is generally protected, and at the same time the transmission channel between the private space and the download source is also protected, ordinary people cannot peep into the transmission. Therefore, when it is determined that the download feature corresponding to the file to be downloaded includes the preset feature matching the private file, that is, it is determined that the file to be downloaded needs to be downloaded to the private space, the The file to be downloaded is transmitted through the transmission channel established between the download feature and the private space, so that the file to be downloaded needs to be protected during the downloading process, effectively improving the security of downloading.

And because the files to be downloaded are finally downloaded to the private space, and the private space is a protected folder, so that the storage and consultation of the files to be downloaded after the download is completed are also protected accordingly, and there is no need to treat the downloaded files After the download is complete, manually encrypt it, which effectively improves the efficiency of encryption and downloading.

An embodiment of the present disclosure provides a method for downloading a file, including: acquiring the download feature corresponding to the file to be downloaded, determining whether the download feature includes a preset feature that matches the private file, and when determining that the download feature includes the preset feature, the The downloaded file is downloaded to the private space, wherein the private space is a space for storing private files. Whether the file to be downloaded needs to be downloaded to the private space is determined by the download feature corresponding to the file to be downloaded, which effectively improves the efficiency of file downloading and improves user experience.

In an embodiment, the above-mentioned download feature corresponding to the file to be downloaded may be a Uniform Resource Locator (Uniform Resource Locator, URL for short) corresponding to the file to be downloaded.

At this time, as shown in Figure 2, the above step S101 can be implemented as step S1011, the above step S102 can be implemented as step S1021, and the above step S103 can be implemented as step S1031:

In step S1011, the Uniform Resource Locator URL corresponding to the file to be downloaded is acquired.

In a practicable manner, when the user needs to download a file, the user can directly input the URL corresponding to the file to be downloaded in the download task box of the downloader, and the URL can be obtained directly at this time.

In another practicable way, the user can confirm the downloaded file by clicking. Since the file to be downloaded corresponds to a URL in the server, the click operation can be used as a trigger condition for obtaining the URL. When the user clicks the file to be downloaded file, the URL is sent directly to the downloader. Wherein, the server is a server used to generate, save, and push a white list containing preset features.

For example: on the mobile phone interface as shown in Figure 3, when the user wants to download movies, Movie 1, Movie 2, Movie 3, Movie 4, Movie 5, and Movie 6 are displayed in the movie library. To download movie 3, the user clicks on the icon of movie 3, and when it is received that the user clicks on the icon of movie 3, the URL corresponding to movie 3 is sent to the downloader.

In step S1021, it is determined whether the URL includes preset key characters matching the privacy file.

In step S1031, when it is determined that the URL includes preset key characters matching the private file, the file to be downloaded is downloaded to the private space.

The key characters mentioned above include but are not limited to the following three types:

The first type: the key character may also be a complete URL.

The second type: the URL will carry the hash value, for example: the URL can be: "http://domain.com/?search=a#hash", where #hash is the hash value in the URL, at this time , you can use the hash value in the URL as the key character above.

The third type: the URL will carry a string composed of %, #, &, letters, numbers, etc., for example: http://www.example.com/index? "index?name=na%26me%3d1&id=id2" in name=na%26me%3d1&id=id2, at this time, the above-mentioned character string in the URL can be used as the above-mentioned key character.

The technical solution provided by the embodiments of the present disclosure may include the following beneficial effects: obtain the URL corresponding to the file to be downloaded, and determine whether the preset key characters in the URL match the private file, and when it is determined that the URL includes the preset key characters, Download the file to be downloaded to the private space. Since it is possible to directly detect whether the URL includes preset key characters to determine whether to save the file to be downloaded in the private space, it is not necessary for the user to determine whether to store the file to be downloaded in the private space, which effectively improves the quality of the file. Download efficiency and improve user experience.

In an embodiment, in the present disclosure, the preset key characters can be directly acquired locally through the client of the downloader.

When multiple historical download URLs are acquired, the historical download URLs are URLs corresponding to files placed in the private space by the user after downloading in the historical download tasks, and then the preset key characters are obtained according to the multiple historical download URLs.

And after the above-mentioned preset key characters are obtained, the preset key characters can also be uploaded to the server.

In another embodiment, the preset key characters can also be acquired through the server. At this point, a plurality of historical download URLs are obtained, which are URLs corresponding to files placed in the private space by the user after the download is completed in the historical download task, and then multiple historical download URLs are uploaded to the server, so that the server according to Multiple historical download URLs get preset key characters. After the server obtains the preset key characters, it can also push these preset key characters to the terminal device, so that after the terminal device obtains the URL corresponding to the file to be downloaded, it can locally determine whether the file to be downloaded needs to be downloaded to Steps in a private space. Of course, the server may not push the preset key characters obtained by itself to the terminal device. Then, when the terminal device obtains the download feature corresponding to the file to be downloaded, it can upload the download feature to the server, so that the server executes the judgment to be downloaded. The step of whether the file needs to be downloaded to the private space, when the server determines that the file to be downloaded needs to be downloaded to the private space, then sends a response message to the terminal device, and the response message is used to instruct the downloader in the terminal device to download the file to be downloaded to a private space. Of course, after the server obtains the preset key characters, it can also generate a white list according to the preset key characters, and push the white list to the client, using the white list as a judgment basis.

In the above implementation manner, the acquisition of multiple historical download URLs may be obtained by the downloader actively detecting the user's download tasks, or may be actively uploaded by the user. This disclosure does not limit the implementation manner of obtaining the historical download URLs.

The above acquisition of preset key characters based on multiple historical download URLs can be achieved in the following ways:

A first implementable manner of acquiring preset key characters according to multiple historical download URLs is: acquiring URLs whose occurrence times exceed a third preset threshold among historical download URLs in the private space are the aforementioned preset key characters.

For example: the third preset threshold is 2, when the obtained historical download URLs are: 111.222.333.444/521, 111.223.333.444/521, 111.222.333.444/521, 111.224.333.444/521, 111.222.333.444/521, where , the number of occurrences of 111.222.333.444/521 is 3, which exceeds the third preset threshold of 2, and the 111.222.333.444/521 is determined to be the preset key character at this time.

At this point, after obtaining the URL corresponding to the file to be downloaded, directly determine whether there is a key character identical to the URL among a plurality of preset key characters, and when it is determined that there is a key character identical to the URL among the multiple preset key characters key character, then it is determined that the file to be downloaded is a file that needs to be saved in the private space.

The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects: the preset key characters are obtained according to the complete historical download URL, so that the coverage of the preset key characters is small, and then it is judged whether the file to be downloaded needs to be saved Higher precision to privacy spaces.

Because the matching granularity is too large and the matching is too rough through a complete URL matching, the matching result is not accurate enough, so that some files that should be stored in the private space are ignored.

Take the network disk as an example: the default key character is "pan.baidu.com/xxx", and the URL corresponding to the file to be downloaded is "pan.baidu.com/x11". Since the two URLs are different, therefore , make sure that "pan.baidu.com/x11" is not the file to be saved in the private space. In fact, "pan.baidu.com/x11" is also a file that the user wishes to save in the private space.

The second achievable way of obtaining preset key characters according to multiple historical download URLs is: obtaining preset key characters according to multiple historical download URLs includes: segmenting each historical download URL to obtain multiple segmentation words; obtaining multiple Segmented words whose occurrence times exceed the fourth preset threshold in the segmented words; use the segmented words exceeding the fourth preset threshold as preset key characters.

After obtaining multiple historical download URLs, segment each historical download URL according to preset rules to obtain multiple segmented words, wherein the preset rules can be input by the user or built in the downloader, The present disclosure does not limit the way of obtaining the preset rules. The preset rules can be segmented for two-word groups, three-word groups, or for users themselves. This disclosure does not limit the segmentation methods indicated in the preset rules. .

For example: the fourth preset threshold is 2, and the following three historical download URLs are obtained: pan.baidu.com/xxx, pan.baidu.com/x11, pan.baidu.com/x12, and the historical download URLs are Segmentation by punctuation, the segmented words obtained by pan.baidu.com/xxx are: {pan, baidu, com, xxx}; the segmented words obtained by pan.baidu.com/x11 are: {pan, baidu, com, x11 };pan.baidu.com/x12 The segmented words obtained are: {pan, baidu, com, x12}, based on the above groups of segmented words, it is judged that the number of occurrences of the segmented word pan is 3, and the number of occurrences of baidu is 3, Com appears 3 times, xxx appears 1, x11 appears 1, and x12 appears 1; at this time, pan, baidu and com can be used as preset key characters.

At this time, when it is detected that the number of preset key characters included in the URL corresponding to the file to be downloaded is greater than or equal to the fifth preset threshold, the file to be downloaded is downloaded to the private space.

For example: the fifth preset threshold is 3, and the preset key characters are 111, 333, 444. When the URL corresponding to the acquired file to be downloaded is: 111.222. Assuming that the key characters are 111, 333 and 444, it is determined that the file to be downloaded corresponding to the URL needs to be saved in the private space.

Another example: the fifth preset threshold value is 3, and the preset key characters are 111, 333, 444. When the URL corresponding to the obtained file to be downloaded is: 111.222.111.444/521, at this time, after detecting the URL included in the URL The preset key characters are 111, 111 and 444, and at this time, it is also determined that the file to be downloaded corresponding to the URL needs to be saved in the private space.

For example, the URL corresponding to the file to be downloaded may also be scored, and when the score is greater than a preset score value, it is determined that the file to be downloaded corresponding to the URL needs to be saved in the private space.

The scoring standard at this time may be: when the URL corresponding to the file to be downloaded includes a preset key character, the score is 1 point; when the URL corresponding to the file to be downloaded includes two preset key characters, the score is 2 points , and so on, and when the score is greater than or equal to 3 points, it is determined that the file to be downloaded corresponding to the URL needs to be saved in the private space.

For example: the preset key characters are 111, 333, 444, when the obtained URL corresponding to the file to be downloaded is: 111.222. There are 3 in total 444, then the score of this URL is 3 points at this time, it will be determined that the file to be downloaded corresponding to this URL needs to be saved in the private space.

The scoring standard at this time can also be: when the URL corresponding to the file to be downloaded includes a preset key character, the score is 1 point; when the URL corresponding to the file to be downloaded includes two preset key characters, the score is 1 2 points, and so on, and when the score is greater than or equal to 2 points, it is determined that the file to be downloaded corresponding to the URL needs to be saved in the private space.

For example: the preset key characters are 111, 333, 444, when the obtained URL corresponding to the file to be downloaded is: 111.222. There are two types of 444, then the score of this URL is 2 points at this time, it will be determined that the file to be downloaded corresponding to this URL needs to be saved in the private space.

From the above analysis, it can be known that "com" is a second-level domain name used for industrial and commercial financial enterprises, so "com" will be included in the URL addresses of industrial and commercial financial enterprises, so "com" is used as the default key alone Characters are imprecise. Therefore, the word formed by the first segmented word exceeding the fourth preset threshold and the second segmented word exceeding the fourth preset threshold can be used as the preset key character, wherein the first segmented word and the second segmented word belong to the same The historical download URL, and the first segmented word and the second segmented word belong to the adjacent relationship.

Continuing with the above example, when the segmented words exceeding the second preset threshold are obtained: pan, baidu and com, judge pan and baidu first, because the pan and baidu belong to the same historical download URL "pan.baidu.com" , and pan and baidu belong to the adjacent relationship in the historical download URL, then pan.baidu can be used as the preset key character to continue to judge baidu and com, because pan and baidu belong to the same historical download URL "pan.baidu. com", and pan and baidu are adjacent in the historical download URL, then pan.baidu.com can be used as the default key character.

Because the URL includes directory names at all levels, taking pan.baidu.com/xxx as an example, the root directory of the website obtained after splitting according to the directory name is pan.baidu.com, and the next step of the root directory of the obtained website is The level directory is xxx. therefore. In another practicable manner, after obtaining multiple historical download URLs, each historical download URL is segmented according to the directory name to obtain multiple directory names, and then preset key characters are obtained according to the directory names.

As shown in FIG. 4 , the third implementable way of obtaining preset key characters according to multiple historical download URLs includes the following steps: In step S201 : segment each historical download URL into directories to obtain multiple directory names.

In step S202: Obtain the directory name whose occurrence times is greater than or equal to the first preset threshold among the plurality of directory names.

In step S203: the directory name whose occurrence times are greater than or equal to the first preset threshold is used as a preset key character.

For example: the first preset threshold is 2, and the following three historical URLs are obtained: pan.baidu.com/xxx, pan.baidu.com/x11, pan.baidu.com/x12, and the historical download URLs are as follows: The directory name is divided to obtain multiple directory names, and the multiple directory names obtained by dividing pan.baidu.com/xxx according to the directory are: {pan.baidu.com, xxx}; for pan.baidu.com/ The multiple directory names obtained by splitting x11 according to the directory are: pan.baidu.com, x11}; the multiple directory names obtained by splitting pan.baidu.com/x12 according to the directory are: {pan.baidu.com , x12}, based on the above groups of directory names, it is determined that the directory name pan.baidu.com has 3 occurrences, xxx 1 occurrences, x11 1 occurrences, x12 1 occurrences; pan.baidu The number of occurrences of .com is greater than the first preset threshold, therefore, pan.baidu.com is used as the preset key character.

The technical solution provided by the embodiments of the present disclosure may include the following beneficial effects: obtain the preset key characters according to the directory name in the historical download URL, so that the obtained preset key characters are more accurate, and then make it possible to judge whether the file to be downloaded needs to be saved Higher precision to privacy spaces.

The fourth possible way to obtain preset key characters based on multiple historical download URLs is: after monitoring that the user downloads the file, there is a behavior of actively placing the downloaded file into the private space, indicating that this is most likely a privacy-related issue. URL. Then, these URLs can be collected and uploaded to the server. The server collects the above-mentioned URLs obtained from many users, and judges whether these URLs are preset key characters.

For example: if more than 50% of the users choose to put the files downloaded from the same URL into the private space, then the URL is determined to be the preset key character.

At this time, a white list can also be preset on the server, and the preset key characters are stored in the white list. Therefore, after the server obtains the above-mentioned preset key characters, it will add the preset key characters to the white list.

Since the client will upload the above historical download URLs to the server periodically or in real time, the server needs to update the above white list according to the preset key characters determined later, so that the coverage of the white list is larger.

Since the whitelist is updated, the server needs to push the updated whitelist to the client at a certain period or in real time.

It is worth noting that the above step of determining whether to download the file to be downloaded to the private space can also be performed by combining the historical download URL and the URL corresponding to the file to be downloaded by using a machine learning method.

In another embodiment, the above-mentioned download feature corresponding to the file to be downloaded may be a file feature in the seed file corresponding to the file to be downloaded.

At this time, as shown in Figure 5, the above step S101 can be implemented as step S1012, the above step S102 can be implemented as step S1022, and the above step S103 can be implemented as step S1032:

In step S1012, the file feature in the torrent file corresponding to the file to be downloaded is acquired, and the file feature in the torrent file includes: the file feature value recorded in the torrent file.

In step S1022, it is determined whether the characteristic value in the seed file is the same as the preset characteristic value matched by the private file.

In step S1032, when it is determined that the feature value in the seed file is the same as the preset feature value matching the private file, the file to be downloaded is downloaded to the private space.

The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects: obtain the file features in the seed file corresponding to the file to be downloaded, and when it is determined that the feature value in the seed file is the same as the preset feature value matching the private file, the The file to be downloaded is downloaded to the private space. Since it is possible to directly determine whether to store the file to be downloaded in the private space according to the characteristic value in the seed file, it is not necessary for the user to determine whether to store the file to be downloaded in the private space, which effectively improves the efficiency of file downloading. And improve the user experience.

When a user downloads a file, not only the download can be performed through the above-mentioned URL, but also the download can be performed through a BitTorrent (abbreviated as: BT) seed.

For the torrent file, the torrent file itself is actually a text-like file. The file itself records the file feature value (for example: digital summary value) of the file to be downloaded. At this time, it can be judged according to the file feature value whether the file to be downloaded needs to be downloaded to the private space.

At this point, obtaining the above-mentioned preset characteristic values can be achieved in the following ways:

1) After obtaining the file characteristic values of multiple historical seed files, the client obtains preset characteristic values according to the file characteristic values of the multiple historical seed files, and the client locally saves these preset characteristic values.

At this point, when the file feature in the torrent file corresponding to the file to be downloaded is obtained, the client can directly perform the above step of determining whether to download the file to be downloaded to the private space according to the preset feature value.

2) After obtaining the file characteristic values of multiple historical seed files, the client obtains preset characteristic values according to the file characteristic values of the multiple historical seed files, and the client uploads these preset characteristic values to the server.

At this time, when the file feature in the torrent file corresponding to the file to be downloaded is obtained, the client sends the file feature in the sub-file to the server, so that the server performs the above determination according to the preset feature value whether to download the file to be downloaded to the private Step in the space, when the server determines that the file to be downloaded needs to be downloaded to the private space, the server may send an indication message to the client, where the indication message is used to instruct downloading the file to be downloaded to the private space.

3) After obtaining the file characteristic values of a plurality of historical seed files, the client sends the file characteristic values of these historical seed files to the server, so that the server obtains a preset characteristic value according to the file characteristic values of a plurality of historical seed files, and Save locally on the server.

At this time, when the file feature in the torrent file corresponding to the file to be downloaded is obtained, the client sends the file feature in the sub-file to the server, so that the server performs the above determination according to the preset feature value whether to download the file to be downloaded to the private Step in the space, when the server determines that the file to be downloaded needs to be downloaded to the private space, the server may send an indication message to the client, where the indication message is used to instruct downloading the file to be downloaded to the private space.

4) after obtaining the file characteristic value of a plurality of historical seed files, the client sends the file characteristic value of these historical seed files to the server, so that the server obtains the preset characteristic value according to the file characteristic value of a plurality of historical seed files, and The server pushes the preset characteristic value to the client.

At this point, when the file feature in the torrent file corresponding to the file to be downloaded is obtained, the client can directly perform the above step of determining whether to download the file to be downloaded to the private space according to the preset feature value.

For example, the method for obtaining the preset feature value includes: after the user downloads a certain file through the torrent file, if the user puts it in the private space after the download is completed, the client will read the downloaded file in the torrent file. The file feature value of the file and report it to the server. The server collects the above-mentioned information uploaded by many users. If it is found that more than a certain percentage of users have put files with the same file feature value into the private space, the file corresponding to the file feature value can be determined as a private file. Then this file feature value can be used as a preset feature value.

At this time, the server may also preset a white list, and the white list stores preset characteristic values. Therefore, after the server obtains the above-mentioned preset characteristic values, it will add the preset characteristic values to the white list.

Since the client will upload the file feature values of the above-mentioned historical seed files to the server periodically or in real time, the server needs to update the above-mentioned white list according to the preset feature values determined later, so that the coverage of the white list is larger.

Since the whitelist is updated, the server needs to push the updated whitelist to the client at a certain period or in real time.

The example method for obtaining preset feature values may also include: after the user downloads a certain file through the seed file, if the user puts the file in the private space after the download is completed, the client will read the already downloaded file in the seed file. Download the file feature value of the file. The client collects the above information uploaded by many users. If it is found that more than a certain percentage of users have put the file with the same file feature value into the private space, it can be determined that the file corresponding to the file feature value is Privacy document. Then the client can use this file feature value as a preset feature value. Afterwards, the client can also upload these preset characteristic values to the server, so that the server can save them.

The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects: Acquire preset feature values according to file feature values of historical seed files, so that the acquired preset feature values are more accurate, and then it is judged whether the file to be downloaded needs to be saved Higher precision to privacy spaces.

It is worth noting that it is also possible to determine whether the file to be downloaded needs to be downloaded to the private space by combining the file feature values of multiple historical torrent files and the file features in the torrent file corresponding to the file to be downloaded through the machine learning method.

Wherein, obtaining the file features in the torrent file corresponding to the file to be downloaded includes: obtaining the file features in the torrent file by using the fifth version of Message Digest Algorithm (MD5), a hash algorithm or a secure hash algorithm.
