Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The embodiment of the invention provides a method and a system for displaying a digital signature, a data editing method and a terminal, which are used for solving the technical problem that the source of coded and decoded data content cannot be determined when a common character coding system is adopted for coding and decoding.
In order to better understand the technical solutions of the present invention, the following detailed descriptions of the technical solutions of the present invention are provided with the accompanying drawings and the specific embodiments, and it should be understood that the specific features in the embodiments and the examples of the present invention are the detailed descriptions of the technical solutions of the present invention, and are not limitations of the technical solutions of the present invention, and the technical features in the embodiments and the examples of the present invention may be combined with each other without conflict.
In data transmission, generally, a current terminal device encodes a service requirement (service data) of a user to obtain encoded data, and then sends the encoded data to a target terminal device. Correspondingly, the target terminal equipment decodes the coded data to obtain service data.
For example, service data "big data has gradually had a positive effect on people's lives" is encoded on the current terminal device, and the resulting encoded data "001001110101001" is transmitted to the target terminal device.
For another example, the target terminal device decodes the encoded data "001001110101001" to obtain the service data "big data has gradually had a positive impact on people's lives".
Through the above scenario, it can be found that, by using a common encoding and decoding method, a source of service data "big data has gradually had a positive influence on the life of people" is determined from "big data of service data" which cannot be decoded by a target terminal device has gradually had a positive influence on the life of people ", so that it is difficult to prevent and control data piracy and illegal data copying.
In detail, assuming that the current terminal device only authorizes the target terminal device to be able to obtain the service data, if the third party steals the encoded data "001001110101001" in the process that the current terminal device transmits the encoded data "001001110101001", there is no difference between the service data obtained by the third party and the service data obtained by the target terminal device. In this case, the sources of the service data obtained by the third party and the service data obtained by the target terminal device cannot be traced.
Therefore, in the method, a data editing terminal can edit a service requirement of a user to obtain a target data content, and then add a check field blended with a data field section code feature and a data source number in each target encoding character of the target data content to obtain an encoded target data content. In this way, when the display terminal decodes the encoded target data content, the data content of the data field corresponding to each target encoding character and the digital signature obtained from the check field can be displayed.
Taking the above example as an example, even if the encoded data "001001110101001" is stolen by a third party, when the third party is decoding the encoded data "001001110101001" to obtain the business data "big data has gradually had a positive influence on the life of people", the business data "big data has gradually had a positive influence on the life of people" carries a digital signature indicating the data source. For example, the digital signature may be a device identification number of the current terminal device or the like. This allows the digital signature to determine that the third party has the act of illegally obtaining the encoded data "001001110101001".
In detail, please refer to fig. 1 in conjunction with the figure, which is a system architecture diagram of a system 100 for displaying digital signatures according to an embodiment of the present invention. As can be seen from fig. 1, the system 100 for displaying a digital signature includes a data editing terminal 1, a display terminal 2, and a rule providing terminal 3.
In the present embodiment, the data editing terminal 1, the display terminal 2, and the rule providing terminal 3 are each configured with a character encoder SCharset.
In the present embodiment, the data editing terminal 1, the display terminal 2, and the rule providing terminal 3 may be electronic devices such as a computer, a PAD, a mobile phone, and the like, and are not limited herein. The data editing terminal 1 can communicate with a plurality of display terminals 2, and similarly, the rule providing terminal 3 can communicate with a plurality of data editing terminals 1.
In the present embodiment, the rule providing terminal 3 may be understood as a Data Provider (Data Provider), and the Data editing terminal 1 may be understood as a consumer (Customer).
It is understood that the system 100 for displaying digital signatures shown in fig. 1 provides a set of codec schemes, which can tag the service data with a data signature, thereby ensuring the determination and tracing of the data source of the service data.
Referring to fig. 2, a flowchart of a method for displaying a digital signature according to an embodiment of the invention is shown, where the method is applied to the system 100 for displaying a digital signature in fig. 1, and the method may include the following steps:
and step S21, the data editing terminal edits the service requirement of the user by adopting the target coding character rule to obtain the target data content.
Step S22, the data editing terminal adds a check field with data field code characteristics and data source number blended into each target code character to obtain the coded target data content.
And step S23, the data editing terminal sends the encoded target data content to the display terminal.
And step S24, the display terminal decodes the encoded target data content, and displays the data content obtained according to the data field and the digital signature for indicating the source of the data content obtained according to the check field.
In step S21, the target data content includes a plurality of target code characters, each target code character including a data field storing data content.
In step S21, the service requirement of the user may be text information, voice information or video information that the user wants to deliver, for example, the service requirement may be text information. In detail, the text information may be a paper T.
In detail, the data editing terminal 1 edits the thesis T by using a target encoding character rule to obtain target data content. In this embodiment, the target data content may be a binary sequence string. The binary sequence string includes a plurality of target code characters, each target code character including a data field storing data content. Referring to fig. 3, for example, one of the target code characters includes data fields X1 and X2 for storing data content and a field X3 for identifying the target code character.
In detail, in step S22, the data editing terminal 1 may add check fields C1 and C2 into the target encoding character, in which the data field byte code characteristics and the data source number are merged. In the present embodiment, the field C1, the field C2, and the field X3 can be understood as check fields.
In step S22, the data source number is acquired by a unique data source coding service center that is uniformly managed and distributed by a root domain name authority similar to the DNS.
The data editing terminal 1 can obtain the encoded target data content through step S22.
In step S24, the data content displayed by the display terminal 2 may be a paper T, and further, the display terminal 2 displays a digital signature indicating the source of the paper T. For example, the digital signature may be a digital number or a character signature.
In step S24, the digital signature may be added to the paper T in the form of a watermark, so that even if the encoded target data content is stolen by a third party, the paper T will carry the digital signature when the third party decodes the encoded target data content and displays the paper T. Through the digital signature carried in the paper T, the data source of the paper T can be determined and traced.
It can be understood that, through the steps S21-S24, the data editing terminal 1 can edit the service requirement of the user to obtain the target data content, and then add the check field with the data field section code feature and the data source number into each target encoding character of the target data content to obtain the encoded target data content. In this way, when the display terminal 2 decodes the encoded target data content, the data content of the data field corresponding to each target encoding character and the digital signature obtained from the check field can be displayed.
In specific implementation, the data editing terminal 1 edits the service requirement of the user by using the target encoding character rule, and in some cases, the source of the target encoding character rule also needs to be traced. To this end, in an alternative embodiment, before step S21, the method may further include the following:
and step S11, the rule providing terminal codes a pre-stored character library, and adds an identification field blended with the data source number to the character library to obtain the target coded character rule.
And step S12, the rule providing terminal sends the target code character rule to the data editing terminal.
In step S11, the character library may be a character library corresponding to the GBK encoding scheme.
It is understood that, through the steps S11-S12, the data editing terminal 1 can obtain the character library carrying the data source number after decoding the obtained target encoding character rule. In this way, the rule providing terminal 3 can verify the validity of the source of the character library in the data editing terminal 1 based on the data source number.
For example, the rule providing terminal 3 only sends the target encoding character rule to the data editing terminal 1, and if it is found that the character library adopted by the third party during encoding carries the data source number, it may be determined that the character library of the third party is illegally acquired.
Through the above, the source of the character library can be determined and traced.
In an alternative embodiment, in step S21, the data editing terminal 1 edits the service requirement of the user by using the target encoding character rule to obtain the target data content, which may specifically include the following contents:
and S211, decoding the target coding character rule by the data editing terminal to obtain a character library carrying the data source number.
Step S212, the data editing terminal searches the conversion characters of the service requirement from the character library, and obtains the target data content according to the conversion characters.
In step S211, the character library carries the data source number, so that the source of the character library can be determined by tracing back the data source number.
In particular implementation, the display terminal 2 does not need to decode all encoded target data content in order to improve the efficiency of determining the source of the data content. In detail, if the encoded target data content does not have the check byte, it may be considered that the encoded target data content is not encoded by the encoding method, and the source of the data content cannot be traced since the encoded target data content does not carry the corresponding digital signature. For this purpose, in step S24, the display terminal decodes the encoded target data content, and displays the data content obtained from the data field and the digital signature indicating the source of the data content obtained from the check field, which may specifically include the following:
step S241, the display terminal determines whether a check field exists in each target code character in the encoded target data content.
Step S242, when a check field exists in each target code character in the encoded target data content, the display terminal determines whether a mapping relationship exists between the check field and the data field in each target code character.
And step S243, when the mapping relation exists between the check field and the data field in each target code character, the display terminal decodes each target code character, and displays the data content obtained according to the data field and the digital signature which is obtained according to the check field and is used for representing the source of the data content.
It can be understood that, before decoding the encoded target data content, the display terminal 2 may determine whether a check field exists in each target code character in the target data content, and further determine whether a mapping relationship exists between the check field and the data field in each target code character, and when a check field exists in each target code character in the encoded target data content and the mapping relationship exists between the check field and the data field in each target code character, the display terminal 2 may decode each target code character, and further display the data content obtained according to the data field and the digital signature obtained according to the check field and used for representing the source of the data content.
In this way, by the determination in steps S241 to S242, it is possible to avoid the display terminal 2 decoding all encoded target data contents when tracing back the data source, thereby reducing the resource consumption of the display terminal 2.
In an alternative embodiment, in step S242, the display terminal determines whether a mapping relationship exists between a check field and a data field in each target code character, which may specifically include the following:
step S2421, the display terminal determines that the first bit of the mapping identifier exists from the check field.
Step S2422, the display terminal determines that the second bit of the mapping identifier exists from the data field.
Step S2423, the display terminal determines whether the first value on the first bit is the same as the second value on the second bit.
Step S2424, when the first value on the first bit is the same as the second value on the second bit, the display terminal determines that the mapping relationship between the check byte and the data byte is satisfied.
In detail, referring to fig. 3 in conjunction, values on bits in the data fields X1 and X2 may be mapped to corresponding bits in the check fields C1, C2, and X3. When checking the mapping relationship, a first value on a first bit of the mapping identifier is determined from the high order bits of the check fields C1, C2 and X3, and then a second value on a second bit is determined from the data fields X1 and X2 according to the mapping identifier. Further, when the first value and the second value are the same, it may be determined that the mapping relationship is satisfied between the check byte and the data byte.
For example, the first bits of the check fields C1, C2, and X3 are each the last of the eight bits in each field. The first value of the first bit of the check field C1 is "0", the first value of the first bit of the check field C2 is "1", and the first value of the first bit of the check field X3 is "1".
In detail, the second value mapped with the first value "0" of the first bit of the check field C1 is the value "0" on the second bit (fifth bit) of the data field X1, the second value mapped with the first value "1" of the first bit of the check field C2 is the value "1" on the second bit (eighth bit) of the data field X2, and the second value mapped with the first value "1" of the first bit of the check field X3 is the value "1" on the second bit (fifth bit) of the data field X2.
It can be understood that by judging whether a mapping relationship exists between the check field and the data field in each target encoding character, the display terminal 2 can be prevented from decoding all encoded target data contents when tracing back the data source, and the resource consumption of the display terminal 2 is reduced.
In detail, when tracing back the data source, the display terminal 2 will decode the target character code only when the encoded target data content satisfies the check field detection condition and the mapping relationship determination condition. And if the encoded target data content does not meet the check field detection condition and the mapping relation determination condition at the same time, the coded target data content is characterized in that no digital signature exists after decoding. In this case, the display terminal 2 may not need to decode the encoded target data content. Thus, the resource consumption of the display terminal 2 is reduced.
It is understood that the manner of decoding each target code character by the display terminal 2 is similar, and for convenience of description, the present embodiment will be described with reference to one of the target code characters.
In an alternative embodiment, in step S243, the display terminal decodes each target encoding character, and displays the data content obtained from the data field and the digital signature obtained from the check field for indicating the source of the data content, which may specifically include the following:
and step S2431, the display terminal decodes the data field in each target code character to obtain the data content for representing the service requirement.
And step S2432, the display terminal decodes the check field in each target code character to obtain a digital signature for representing the data content source.
And step S2433, the display terminal displays the data content added with the digital signature.
In step S2432, the data field byte code feature and the data source number are included in the digital signature.
It is understood that through steps S2431 to S2433, the display terminal 2 can display the digital signature together when displaying the data content. In this way, the source of the data content can be traced through the digital signature.
On the basis of the above, please refer to fig. 4, which is a flowchart of a data editing method according to an embodiment of the present invention, the digital signature processing method is applied to the data editing terminal 1 in fig. 1, and the method may include the following steps:
step S31, editing the service requirement of the user by adopting the target code character rule to obtain the target data content, wherein the target data content comprises a plurality of target code characters.
Step S32, add check fields with data field byte code characteristics and data source numbers into each target code character to obtain the coded target data content.
And step S33, sending the encoded target data content to a display terminal, so that the display terminal decodes the encoded target data content, and displays the data content obtained according to the data field and the digital signature obtained according to the check field and used for indicating the source of the data content.
In step S31, each target encoding character includes a data field storing data.
It is understood that, since the implementation principle of the step S31-step S33 is similar to that of the step S21-step S24 in fig. 2, no further description is made here.
On the basis of the above, the embodiment of the present invention provides a data editing terminal 1.
In detail, fig. 5 is a block diagram of a data editing terminal 1 according to an embodiment of the present invention, where the data editing terminal 1 includes:
the editing module 11 is configured to edit a service requirement of a user by using a target code character rule to obtain a target data content, where the target data content includes a plurality of target code characters, and each target code character includes a data field for storing data.
