Embodiment Construction

[0015] This example uses the attached figure 1 , 2 Describe blockchain information storage, privacy protection, and information inspection methods:

[0016] The house purchase contract, the blank format contract sample and its hash value, to ensure that the version content of the format contract is consistent.

[0017] The user only needs to fill in the blanks of the contract (including relevant person information, etc.), selection, and postscript to complete the contract;

[0018] After hashing the above content, the hash value 2 is obtained, and the original contract is completed;

[0019] The house buyer, house seller, and witnesses can sign 3 in turn, and attach the corresponding public key for verification;

[0020] The private key of the real estate registration center signs 4 and hashes to obtain a hash value 5, and saves the public key 6 together on the blockchain 11;

[0021] House buyers, house sellers, witnesses, and real estate registration centers sign the abo...

Abstract

The invention discloses a block chain information archiving and privacy protection method. The block chain information archiving and privacy protection method comprises the steps of adding random number generation Hash values to information needing archiving; then signing by an interest-related person or a eyewitness and generating Hash values; and finally recording at a block chain. Some information needing archiving is formatting and separable formatting information and self-filling information respectively stored and subjected to Hash verification, such as gap-filling information, selection information, postscript information, random number information (for preventing brute force attack). Data which are encrypted by using a public key only can be decrypted by a relevant person who knows the original information by using a private key; a third party verifies true and false of the information; and the encrypted information can be disclosed for a judicial institution if judiciary involvement is needed.

Description

technical field [0001] The present invention relates to the technical field of the Internet, especially technologies such as block chain, information storage certificate, and privacy protection. Background technique [0002] Existing Internet technology does not have a good or convenient way to ensure that information is not tampered with, and there is no way to automatically execute contracts through procedures. Liability for breach of contract also needs to be handled through complicated judicial procedures, which still requires a lot of manpower and material resources . Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned existing technologies, the blockchain information storage and privacy protection method of the present invention can ensure the authenticity of information or contracts, the blockchain program can automatically execute the contract, and the liability for breach of contract can also be automatically executed....
