Embodiment 1

[0058] refer to figure 1 , a data redundancy encryption method suitable for execution in a computing device, comprising the following steps:

[0059] Obtain the data to be encrypted 101;

[0060] In a preferred embodiment of the present invention, when the data to be encrypted contains non-digital data, the non-digital data can be converted into digital data by standard ASCII codes, and then encrypted; those skilled in the art should understand that the encrypted The data in a database can be a single piece of data, or several pieces of data or some or all of the data in the database.

[0061] Obtain the identification code 102;

[0062] Wherein the identification code is a combination of numbers or a random number with an identification function. Wherein, the random numbers in this embodiment are pseudo-random numbers or quasi-random numbers. Therefore, the random number of the present invention can be reproduced by combining the random seed and the method of generating t...

Abstract

The invention belongs to the technical field of information security, and relates to a data redundancy encryption method, a redundancy encryption data identification method and device, and a storage medium. The data encryption method comprises the following steps: acquiring to-be-encrypted data; obtaining an identification code; encrypting the identification code to obtain a ciphertext; and addingthe ciphertext into the redundant data bit of the to-be-encrypted data to obtain encrypted data. In addition, the invention also provides a method for identifying the data obtained by the encryptionmethod. Through the data encryption and identification method provided by the invention, piracy can be effectively prevented; meanwhile, evidence obtaining and right protection after the data is stolen are also facilitated; in addition, the data encryption bit is located on the invalid bit of the data, so that the data precision is not influenced.

Description

technical field [0001] The invention belongs to the technical field of information security, and relates to a data redundancy encryption method, a data identification method, equipment and a storage medium. Background technique [0002] Data encryption is currently the most reliable way for computer systems to protect information. It uses cryptographic technology to encrypt information, realize information concealment, and thus play a role in protecting information security. [0003] In the prior art, it is impossible to track the source of the data to be encrypted, which makes it difficult to obtain evidence after the data is stolen. Once the data is stolen, it is difficult for the data owner to prove the source of the stolen data. Contents of the invention [0004] The object of the present invention is to provide a data redundancy encryption and identification method, device and storage medium in order to overcome the defects of the prior art. [0005] To achieve the ...
