Embodiment 1

[0028] According to an embodiment of the present invention, an embodiment of an anti-tampering method for private information based on blockchain technology is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be implemented in a computer system such as a set of computer-executable instructions and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0029] figure 1 It is a flow chart of a method for preventing tampering of private information based on blockchain technology according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0030] Step S102, obtaining the privacy data to be processed;

[0031] Step S104, performing image processing on the privacy data to be processed to obtain a mirror image file, and performing segmentation processin...

Embodiment 2

[0071] The present invention also provides an anti-tampering system for private information based on blockchain technology, which is used to implement the anti-tampering method for private information based on blockchain technology provided by the above-mentioned content of the embodiment of the present invention. The following is provided by the embodiment of the present invention The specific introduction of the anti-tampering system for private information based on blockchain technology.

Abstract

The invention provides a privacy information tamper-proofing method and system based on a blockchain technology, and relates to the technical field of data security, and the method comprises the steps: obtaining to-be-processed privacy data; Performing mirror image processing on the to-be-processed privacy data to obtain a mirror image file; Carrying out segmentation processing on the to-be-processed private data to obtain a plurality of data blocks; Storing the mirror image file and the plurality of data blocks in a network node of a block chain, each network node being provided with a key pair; If the first request information is obtained, the first request information is forwarded to a block chain, so that the block chain carries out key authentication on a public key carried in the first request information, and the first request information is request information for modifying a first privacy field in the to-be-processed privacy data; And if the authentication is passed, modifyingthe first privacy field stored in the block chain network, thereby solving the technical problem that the privacy data is easily tampered in the prior art.

Description

technical field [0001] The present invention relates to the technical field of data security, in particular to a method and system for preventing tampering of private information based on block chain technology. Background technique [0002] The need to protect an enterprise's sensitive employee, customer and business data is on the rise, wherever it resides. So far, most data theft cases have originated from the malicious intrusion of production databases by individual hackers. Given the significant legal liability and negative publicity that a series of well-known and costly thefts have created for victimized companies, defenses and methods against such attacks are rapidly becoming more sophisticated, but attackers are also pressing ahead. [0003] While the industry has responded to the worst forms of data theft, many computer systems remain vulnerable at some level. Today's new data security procedures have yet to actually touch and protect an important layer of data: ...
