The first embodiment is as follows:
the invention provides a data sharing method for a cloud server, and fig. 1 shows a flowchart of the data sharing method for the cloud server in this embodiment.
As shown in fig. 1, in this embodiment, the cloud server first receives live time sharing data with information about live time inserted in the data to be shared, which is sent by a sending end in step S101. Wherein the survival time comprises a survival time period or a survival deadline for sharing the data. In this embodiment, the shared data is image information, but the present invention is not limited thereto, and in other embodiments according to the present invention, the shared data may also be other data, such as video information.
In this embodiment, when a user shares a picture with a friend, the user first takes or selects a picture for sharing at a sending end, and inserts information about the survival time into picture data, thereby obtaining the shared data with the survival time.
In order to ensure the security of the shared data with the survival time, the shared data with the survival time can be encrypted before the sending end uploads the data. The sending end generates a unique encryption key according to the information with the shared data with the survival time and the sending end information, and data conversion is carried out on the shared data with the survival time through the key, so that encryption of the shared data with the survival time is realized.
In addition, the sending end needs to consume data flow in the process of uploading data, so in order to save the data flow, the sending end can also compress the encrypted shared data with the survival time and upload the compressed data to the cloud server.
The cloud server receives and stores the compressed sharing data with the time-to-live uploaded by the sending end in step S102, and decompresses the sharing data to obtain the encrypted sharing data with the time-to-live. The cloud server then decrypts the shared live time data according to the received key in step S103, so as to obtain information about the live time. In this embodiment, the information about the survival time includes a survival time length for sharing the data, but the present invention is not limited thereto, and in other embodiments according to the present invention, the information about the survival time may further include other information, such as a survival deadline for sharing the data.
In this embodiment, after receiving the shared data with the survival time sent by the sending end, the cloud server automatically reminds the corresponding receiving end to extract the data, and if the corresponding receiving end closes the automatic reminding function, the cloud server resumes automatic reminding when the user actively starts the automatic reminding function next time.
When the receiving end accesses the cloud server to obtain the compressed shared data with the survival time, the cloud server sends the compressed shared data with the survival time to the receiving end in step S104, and performs timing in step S105.
In step S106, the cloud server determines whether the timing result in step S105 reaches the survival time for sharing the data. If yes, executing step S107, and deleting the live time shared data stored in the cloud server; if not, the timing is continued. In this embodiment, in order to enable the user to obtain better user experience, the cloud server deletes the sharing data with the survival time stored in the cloud server and sends a notification to the sending end, so as to inform the sending end that the sharing data with the survival time in the remote server has been deleted. And completing the data sharing process of the cloud server.
It should be noted that, in other embodiments according to the present invention, the cloud server may also determine whether to delete the shared data with the lifetime by using other methods.
For example, when the information about the survival time includes the survival time length or the survival deadline for sharing the data, the cloud server may further delete the shared data with the survival time by using the following corresponding method:
a. deleting the sharing data with the survival time stored in the cloud server after the preset survival time length passes since the sharing data with the survival time is received;
b. and deleting the sharing data with the survival time stored in the cloud server when the survival deadline of the sharing data with the survival time is reached.
According to the data sharing method of the cloud server, the cloud server can automatically destroy the data for sharing after the data for sharing in the cloud server reaches the set survival time, so that the security of the data for sharing is improved, and the possibility that the privacy of a user is revealed is reduced.
Example two:
the invention also provides a data sharing method of the intelligent terminal, and a flow chart of the method is shown in figure 2.
As shown in fig. 2, in this embodiment, the smart terminal serves as a receiving end to receive the sharing data with survival time, in which the information about the survival time is inserted into the sharing data sent from the cloud server in step S201. In this embodiment, the data to be shared includes image information.
When the user shares pictures, the information about the survival time is inserted into the shared data at the sending end, and the shared data with the survival time is formed. In this embodiment, the data to be shared is image information, and the information about the survival time includes the survival time length of the data to be shared, but the present invention is not limited thereto.
The cloud server receives the sharing data with the survival time and stores the sharing data, and the intelligent terminal accesses and obtains the sharing data with the survival time stored in the cloud server in step S201 and stores the received sharing data with the survival time in step S202.
Finally, in step S203, the intelligent terminal destroys the sharing data with the survival time stored in the intelligent terminal according to the information about the survival time.
Fig. 3 shows a specific flowchart of the intelligent terminal data sharing method.
As shown in fig. 3, the intelligent terminal serving as the receiving end receives the shared data with lifetime sent by the cloud server in step S301, and stores the received shared data with lifetime in step S302, the process and principle of which are the same as those in step S201 and step S202, and details are not repeated here.
In order to ensure the security of the data and save the data traffic, in this embodiment, the live time shared data received by the intelligent terminal in step S201 is the live time shared data that is successively encrypted and compressed. Therefore, after receiving the shared data, the intelligent terminal further needs to decompress the received shared data with time to live in step S303 in order to display the shared data, so as to obtain the encrypted shared data with time to live. Then, in step S304, the smart terminal decrypts the encrypted shared data with time-to-live according to the key received from the sending end, so as to obtain information about the time-to-live and data for sharing.
In step S305, the smart terminal displays the acquired shared data and the information about the survival time. In this embodiment, the information about the survival time includes a survival time length for sharing the data, but the present invention is not limited thereto, but according to other embodiments of the present invention, the information about the survival time may further include a survival deadline for sharing the data, and the like.
In this embodiment, the intelligent terminal displays the data to be shared and the survival time of the data to be shared in step S305, and performs timing with the start point of displaying the data to be shared in step S306.
In order to further improve the security of the data to be shared, in this embodiment, the intelligent terminal monitors the screen capture or screen capture processing process of the intelligent terminal in step S307 when displaying the data to be shared, and determines whether the screen capture or screen capture processing process of the intelligent terminal is triggered in step S308.
If the screen capture or screen capture processing process of the intelligent terminal is triggered, the intelligent terminal sends information about the screen capture or screen capture of the data to be shared to the cloud server or the intelligent terminal (i.e., the sending terminal) providing the data to be shared in step S309, and then step S310 is executed to determine whether the timing duration reaches the survival duration of the data to be shared. If the screen capture or screen capture processing process of the intelligent terminal is not triggered, step S310 is executed to determine whether the timing duration reaches the survival duration for sharing data.
It should be noted that, in other embodiments according to the present invention, the intelligent terminal may also be prevented from performing screen capture or screenshot processing on the received shared data in other manners. When the intelligent terminal displays the data to be shared, the screen capture or screen capture of the data to be shared can be avoided by stopping the screen capture processing process of the intelligent terminal. The implementation method comprises the steps that when the intelligent terminal displays the data to be shared, a response function about a screen capture or screenshot thing in an operating system of the intelligent terminal is modified, so that when the intelligent terminal displays the data to be shared, the response function does not perform screen capture or screenshot processing, and only prompt information about that the data to be shared cannot be captured or screenshot is displayed for a user.
In the process of timing by the intelligent terminal, in step S310, it is determined whether the timing duration reaches the survival duration for sharing data. If the timing duration reaches the data survival duration, destroying the shared data with survival time in the intelligent terminal in step S311; if the time length of the timing does not reach the data survival time length, the step S306 is returned to continue the timing.
It should be noted that, in other embodiments according to the present invention, the intelligent terminal may also determine whether to delete the shared data with live time stored in the intelligent terminal in other manners, for example, the following methods:
when the information on the survival time includes the survival time for sharing the data, the intelligent terminal deletes the sharing data with the survival time stored in the intelligent terminal after the preset survival time passes since the sharing data with the survival time sent by the cloud server is received;
when the information on the survival time comprises the survival deadline for sharing the data, the intelligent terminal deletes the sharing data with the survival time stored in the intelligent terminal when the survival deadline is reached.
In order to enable a user to obtain better user experience, in this embodiment, after the shared data with lifetime stored in the intelligent terminal is deleted, the intelligent terminal (i.e., the receiving end) may notify the sending end that the shared data with lifetime stored in the intelligent terminal is deleted.
And the data sharing process of the intelligent terminal is completed.
According to the data sharing method of the intelligent terminal, the intelligent terminal automatically destroys the data for sharing when the data for sharing in the intelligent terminal reaches the preset survival time, so that the security of the data for sharing is improved, and the privacy of a user is prevented from being revealed.
