Detailed Description
The analysis of the prior art shows that in the process of data interaction, a thief is easy to steal data because the data interaction process is performed in a non-closed environment, so that the thief can intervene in the data interaction process or find the interaction data through the interaction trace. In the prior art, data to be transmitted is encrypted by using a secret key to improve confidentiality of data interaction. This approach requires that the key be sent to the terminal so that the terminal can decrypt the encrypted data, which makes it possible for a thief to decrypt the encrypted data by analyzing the encrypted data and the key transmitted during the interaction. Therefore, it is desirable to provide a new data interaction method to improve the confidentiality.
An embodiment of the present specification provides a data interaction method, which receives a data acquisition request sent by a browser, queries data corresponding to the data acquisition request according to the data acquisition request, encrypts the data corresponding to the data acquisition request in a picture format to obtain an encrypted picture, and sends the encrypted picture to the browser of a terminal corresponding to the request, so that the browser decrypts the encrypted picture by using a decryption rule prestored in the terminal to obtain the data corresponding to the data acquisition request.
The data is encrypted in the format of the picture, and the encrypted picture is sent to the terminal, so that a divulger is difficult to obtain a mode of decrypting the picture through an interaction process, and the confidentiality is high.

Program code for carrying out operations for aspects of the present invention may be written in any combination of one or more programming languages, including an object oriented programming language such as Java, C + + or the like and conventional procedural programming languages, such as the "C" programming language or similar programming languages. The program code may execute entirely on the user's computing device, partly on the user's device, as a stand-alone software package, partly on the user's computing device and partly on a remote computing device, or entirely on the remote computing device or server. In the case of a remote computing device, the remote computing device may be connected to the user computing device through any kind of network, including a Local Area Network (LAN) or a Wide Area Network (WAN), or may be connected to an external computing device (e.g., through the internet using an internet service provider).
In summary, the invention may be implemented in hardware, or in software modules running on one or more processors, or in a combination thereof. Those skilled in the art will appreciate that some or all of the functionality of some or all of the components in embodiments in accordance with the invention may be implemented in practice using a general purpose data processing device such as a microprocessor or a Digital Signal Processor (DSP). The present invention may also be embodied as apparatus or device programs (e.g., computer programs and computer program products) for performing a portion or all of the methods described herein. Such programs implementing the present invention may be stored on computer-readable media or may be in the form of one or more signals. Such a signal may be downloaded from an internet website or provided on a carrier signal or in any other form.
While the foregoing embodiments have described the objects, aspects and advantages of the present invention in further detail, it should be understood that the present invention is not inherently related to any particular computer, virtual machine or electronic device, and various general-purpose machines may be used to implement the present invention. The invention is not to be considered as limited to the specific embodiments thereof, but is to be understood as being modified in all respects, all changes and equivalents that come within the spirit and scope of the invention.
Claims (9)
1. A data interaction method, comprising: receiving a data acquisition request sent by a browser, wherein the data acquisition request carries a format conversion request; inquiring data corresponding to the data acquisition request according to the data acquisition request; encrypting the data corresponding to the data acquisition request in a picture format according to an encryption rule prestored in a terminal or a server to obtain an encrypted picture, wherein the encrypting comprises setting a CORS protocol and setting the content format of the data in the picture format; and sending the encrypted picture to a browser of the terminal corresponding to the request, so that the browser decrypts the encrypted picture by using a decryption rule prestored in the terminal to obtain the data corresponding to the data acquisition request.
2. The method of claim 1, wherein the receiving a data acquisition request sent by a browser comprises: receiving a data acquisition request carrying a format conversion request; the encrypting the data corresponding to the data obtaining request in a picture format to obtain an encrypted picture includes: and encrypting the data corresponding to the data acquisition request in a picture format according to the format conversion request to obtain an encrypted picture.
3. The method according to any one of claims 1-2, wherein the receiving a data acquisition request sent by a browser further comprises: and receiving a data acquisition request which is sent by the browser and comprises a cross-domain uniform resource locator.
4. A data interaction method, comprising: sending a data acquisition request to a server, wherein the data acquisition request carries a format conversion request, so that the server queries data corresponding to the data acquisition request according to the data acquisition request, encrypts the data corresponding to the data acquisition request in a picture format to obtain an encrypted picture, and sends the encrypted picture to a browser of a terminal corresponding to the request, wherein the encrypting comprises setting a CORS protocol, and setting a content format of the data in the picture format; receiving the encrypted picture; and decrypting the encrypted picture by using a decryption rule prestored in the terminal, wherein the decrypting comprises decrypting the picture format of the encrypted picture into a content format of data to obtain the data corresponding to the data acquisition request.
5. The method of claim 4, the sending a data acquisition request to a server, comprising: sending a data acquisition request carrying a format conversion request to a server, wherein the format conversion request enables the server to encrypt data corresponding to the data acquisition request in a picture format to obtain an encrypted picture.
6. The method of any of claims 4-5, the sending a data acquisition request to a server, further comprising: a data acquisition request is sent that includes a cross-domain uniform resource locator.
7. A data interaction device, comprising: the receiving module is used for receiving a data acquisition request sent by a browser, wherein the data acquisition request carries a format conversion request; the encryption module is used for inquiring data corresponding to the data acquisition request according to the data acquisition request, encrypting the data corresponding to the data acquisition request in a picture format according to an encryption rule prestored in a terminal or a server to obtain an encrypted picture, wherein the encrypting comprises setting a CORS protocol, and setting the content format of the data in the picture format; and the sending module is used for sending the encrypted picture to a browser of the terminal corresponding to the request, so that the browser decrypts the encrypted picture by using a decryption rule prestored in the terminal, and the decryption includes decrypting the picture format of the encrypted picture into a content format of data to obtain the data corresponding to the data acquisition request.
8. An electronic device, wherein the electronic device comprises: a processor; and a memory storing computer-executable instructions that, when executed, cause the processor to perform the method of any of claims 1-6.
9. A computer readable storage medium, wherein the computer readable storage medium stores one or more programs which, when executed by a processor, implement the method of any of claims 1-6.
