Description

A method and system for realizing information forwarding

technical field

The invention relates to the field of information forwarding, in particular to a method and system for realizing the forwarding of information without modification.

Background technique

Information service (Message Service) is the digital service with the broadest market in mobile communication at present. With the development of communication technology, the content provided by the message service is also increasingly rich, currently mainly including: short message (SMS), multimedia message (MMS), instant message (IM), email (E-mail) and so on. Information users will often forward information to achieve the purpose of sharing resources.

At the same time, the requirements for the authenticity of information sources are also getting higher and higher. For example, when a user receives a threatening message, the message will be forwarded to the alarm center, indicating that he is being threatened by others. However, the current information forwarding is actually the process of sending information. The message is sent directly according to the address of the receiver, and the content of the message is directly sent to the receiver. The sender displayed on the receiver's mobile phone is a general mobile phone number. Moreover, since the forwarder of the information can edit the forwarded information, the receiver cannot judge the authenticity of the information content, nor can he confirm the true source of the message. Even if the source of the information can be identified in the current E-mail forwarding function, since the forwarded information can be edited, it is actually impossible to judge the authenticity of the information.

Contents of the invention

Therefore, the object of the present invention is to provide a method and system for realizing information forwarding, so as to solve the authenticity problem of forwarded information.

The invention provides a method for realizing information forwarding, comprising the following steps:

A. The information center receives the information forwarded by the information sender, and the forwarded information includes a trust field added by the information sender;

B. The information center matches the information content of the forwarded information containing the trust field with the information content of all the information received by the information sending end stored in the information center, if the information content of the forwarded information is exactly the same as that of the forwarded information information content, proceed to the following steps;

C. The information center adds the trusted number as the information sender to the forwarding information, and sends the forwarding information containing the trusted number to the information receiving end, and the trusted number is used to make the information receiving end confirm receipt The forwarding information is the forwarding information with the content of the information unchanged.

Wherein, when the information sender in step A forwards the information to the information center, a trust field is added in the address of the information receiver in the forwarded information or in the content of the forwarded information.

Wherein, the trust field is a trust label pre-defined by the information center indicating that the content of the forwarded information has not been changed.

Wherein, after the step A, the steps before the step B also include:

B1. Check whether the forwarding information contains a trust field, and if so, proceed to the following steps;

Said step B comprises the steps of:

B2. Match the information content of the forwarding information containing the trust field with the information content of all the information received by the information sending end stored in the storage module in the information center, if the information matching the forwarding information is found If the information content is exactly the same, proceed to the following steps;

B3. Store relevant content of the forwarding information in the storage module.

Wherein, the related content of storing the forwarding information in step B3 includes: information number.

Wherein, the related content of storing the forwarding information in step B3 also includes information source tag, information sender and information receiver.

Wherein, the information source label includes the addresses of the indirect sender and the direct sender of the information corresponding to the forwarding information.

Wherein, the information sender is a special trust number set by the information center, and the receiver of the information confirms that the information is forwarded information without modification of the information content by using this number.

Wherein, the method for the information center in step C to send the information to the information receiving end includes the following steps:

C1, judging whether the source label of the forwarded information is empty, if not empty, then execute step C2;

C2. Combining the information content of the forwarded information and the source label into the delivered content;

C3. Add the trusted number as the information sender to the forwarding information containing the combined delivered content, and deliver the forwarded information including the trusted number and the delivered content to the information receiving end .

Wherein, the information content described in step C2 and the source tag are separated by a special delimiter, which is set by the information center.

This Fangming also provides a system for forwarding information with unmodified content, including an information center that communicates with the information sending end and the information receiving end. The information center includes:

The information receiving module is used to receive the information forwarded by the information sending end, and pass the forwarded information to the information processing module;

An information processing module, configured to match the information content of the forwarded information with the information content of all the information received by the information sending end stored in the storage module;

The storage module is used to save all the information received by the information sending end, and when the information processing module matches the information content that is exactly the same as the information content of the forwarding information, save the information number and information of the forwarding information Content, source label, information sender and information receiver, the source label includes the indirect sender and direct sender of the forwarded information, and the information sender is a trust number set by the information center;

The information sending module is used to combine the information content and the source tag of the forwarding information into the delivery content when the information processing module matches the information content that is exactly the same as the information content of the forwarding information, and deliver it to the information Receiving end.

As can be seen from the above description, the present invention adds a trust field to the forwarding information selected by the information sending end, and the information center matches the forwarding information with the original message content stored in the storage module. If the information content of the two is consistent, A source tag is added to the content of the forwarded information, and then sent to the information receiving end. In this way, the information receiving end can determine that the content of the message has not been changed and is trustworthy.

It can be said that the present invention increases the credibility of information sources, thereby increasing the credibility of information content and effectively preventing the dissemination of false information.

Detailed ways

The invention provides a technical solution for realizing the forwarding of information without modification, which can ensure the authenticity of the forwarded information. The core idea of the present invention is to add a "trust field" in the address field or information content of the forwarded information. After the information center detects the trust field, the forwarded information will be stored in the All the received information is matched, and the information content of the two is consistent. When the information center sends the trust information, it will use a special trust number set in advance as the information sender, and identify the direct sender and indirect sender of the information. Or, the information receiving end can judge that the content of the information has not been changed according to the special number, and can know the true source of the forwarded information.

Fig. 1 shows the composition of the information center in the information forwarding system of the present invention, including an information receiving module, an information processing module, a storage module and an information sending module.

The information receiving module is used to receive the information forwarded by the information sending end, and deliver the forwarded information to the information processing module.

The information processing module is the core component of the information center when processing information forwarding. It mainly realizes the analysis and processing of the content of the forwarded information, and matches the forwarded information with all the information received by the information sender stored in the storage module, and judges the two Whether the content of the author is consistent.

The storage module is used to save the information when the information processing module matches the information content exactly the same as the information content of the forwarded information, and save the information number, information content, information source label, information sender and information receiver of the forwarded information.

The information sending module is used to combine the information content and the source tag of the forwarding information into the delivery content when the information processing module matches the information content that is exactly the same as the information content of the forwarding information, and deliver it to the information receiving end.

Referring to the structure diagram of the information center in Figure 1, and referring to the data processing process of the information center in Figure 2, the following steps are included when forwarding information whose content has not been changed:

In the process of forwarding information with unchanged information content, the information sender encapsulates the address of the receiver so that the information center can distinguish that this is a request for forwarding information with unchanged information content. A "trust field" is added to the receiver address field, and then the "trust field" and the receiver address are encapsulated to distinguish it from ordinary information forwarding.

After receiving the forwarding information, the information receiving module in the information center transmits the forwarding information to the information processing module for processing.

The information processing module first unpacks the recipient address field of the forwarded information received, and if it is found that the address field does not contain a "trust field", it will switch to the normal information forwarding process. If it contains a "trust field", then Perform matching processing on the received information, and judge whether the content of the forwarded information has been changed. The information processing module calls all the information received by the direct sender of the forwarded information to the storage module, and matches the content of the forwarded information one by one. If the matching information with the same content as the forwarded information can be found, it indicates that the forwarded information The direct sender of the message has not modified the information; otherwise, it indicates that it is ordinary forwarding, and it is converted to the ordinary information forwarding process.

After confirming that the content of the forwarded information has not been changed, the information center generates a unique information number and registers it in the corresponding field of the storage module, indicating that this is a new piece of information. The information content of the forwarding information is registered in the corresponding field of the storage module, and the indirect sender and direct sender corresponding to the matching information are used as the source tags of the information, and registered in the corresponding field of the storage module. Among them, the indirect sender and the direct sender are separated by special symbols, and the separator is set by the information center. At the same time, in order to distinguish the indirect sender from the direct sender, you can mark the indirect sender and the direct sender. The specific mark is set by the information center, and the mark to distinguish the indirect sender from the direct sender is also set by the information center.

Since the content of the forwarded information has not been changed, the information center defines a special "trust number" as the corresponding field registered in the storage module by the information sender to indicate that the information is trustworthy and the source is true. For example, if the information center defines 86xxx as the sender of information forwarding with unchanged content, once the information receiving end receives the information that the information sender is 86xxx, it can judge that the content of the information has not been changed.

The information processing module unpacks the recipient address field of the forwarded information received without modification, strips off the trust field, and registers the remaining field as the recipient of the information in the corresponding field of the storage module.

At this point, the data processing process ends, and then the information delivery process is executed.

In the process of sending information, it is first judged whether the source label field of the corresponding information is empty, and if it is empty, the information content will be used as the delivery content; otherwise, the information content and the source label will be combined into the delivery content, where the information content and The source tags are separated by a special delimiter, which is set by the information center, and the next step is the information distribution process, which is consistent with the existing information distribution process and will not be described here.

Table 1 is the information format of the information center.

Information number information source tag sender receiver

Table 1

Table 2 is an example of forwarding without changing the information content.

Table 2

As shown in Table 2, message number, message content, source label, sender and receiver are all fields in the storage module. The first column in the table refers to the sending operation of the information, and there are two types of forwarding without changing the content of the information and ordinary forwarding. If it is an ordinary information forwarding, its source label field is empty, and the sender field is an ordinary user address; if it is forwarding without changing the content of the information, its source label field is not empty, and the information sender field is Special number, such as "86xxx" assumed in the table, the sender field is the special information number set by the information center, indicating that the information content of the forwarded information has not been changed.

When the information receiver receives the forwarded information, the colon is the separator between the information content and the source label, and the comma is the internal separator of the source label. The separator is preset by the information center and is not limited to colons and commas. The colon separates the sent content received by the receiver into two parts, the front is the information content, and the back is the source label, which is the source of the information, that is, the indirect sender and the direct sender. In the table, a special mark "T" is added before the direct sender, and a special mark "F" is added before the indirect sender. The specific mark is set by the information center, and it is only for distinguishing the direct sender from the indirect sender. Of course, the front and rear positions of the information content and source labels can be interchanged, as can the positions of the direct sender and the indirect sender.

It can be seen from the table that even if the sent content received by the information receiver carries a specific delimiter or the marks of the direct sender and the indirect sender, it still cannot be confirmed that the information is trustworthy (such as ***3 information), and It is necessary to check whether the sender of the information displayed on the receiving end is the special trusted number set by the information center. Therefore, the sent content received by the information receiving end contains the delimiter and the marks of the direct sender and the indirect sender, and it cannot be determined that the content of the forwarded information has not been changed.

When forwarding information with unchanged information content, in addition to encapsulating the address of the receiver, the content of the sent information can also be encapsulated, so that the information center can distinguish that this is a request for forwarding information with unmodified information content.

When forwarding information with unchanged information content, the transmitted content is encapsulated, so that the information center can distinguish that this is a request for forwarding information with unchanged information content. In the encapsulation process, a "trust field" is first added to the information content field, and then the "trust field" and information content are encapsulated to distinguish it from ordinary forwarding.

The information format stored in the information center is shown in Table 1, and the data processing process of the information center is shown in Figure 2.

After the information receiving module receives the information, it starts the process of processing the data by the information processing module.

The information processing module first unpacks the content of the received information, and if it finds that the content field contains a "trust field", it indicates that the sender is requesting to forward the information with unmodified content, and at the same time unpacks the trust field and the information content. point. Otherwise, it indicates that it is common forwarding, and turns to perform normal information processing.

The information processing module performs matching processing on the content of the received information, and judges whether the content of the forwarded information has changed. The information processing module calls all the information received by the direct sender of the forwarded information to the storage module, and carries out content matching with the forwarded information one by one. During the unpacking process, the content field after stripping the "trust field") is exactly the same as the matching information, indicating that the direct sender of the forwarded information has not modified the information; otherwise, it indicates that it is a normal forwarding, and it is converted to a normal information forwarding process .

The information center generates a unique information number for the forwarded information, and registers it in the corresponding field of the storage module, indicating that this is a new piece of information, and registers the information content after the unpacking process and stripping the "trust field" into the corresponding field of the storage module .

The information center registers the indirect sender and direct sender corresponding to the matching information as the source tag of the information in the corresponding field of the storage module. Wherein, the indirect sender and the direct sender are separated by a special symbol, the separator is set by the information center, and the mark for distinguishing the indirect sender from the direct sender is also set by the information center.

The information center defines a special "trust number" as the corresponding field registered in the storage module by the information sender, to indicate that the information is trustworthy and the source is true. For example, if the information center defines 86xxx as the sender of information forwarding without modification, once the information receiving end receives the information that the sender is 86xxx, it can judge that the content of the information has not been modified and can be trusted.

The information center directly registers the address of the information receiving end in the corresponding field of the storage module.

So far, the data processing flow of the information center is completed, and then the information distribution flow is executed, and the technical solution is the same as that described above, which is omitted here.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of the present invention. within the scope of protection.
