Private key generation and decryption method and system based on face recognition

Abstract

The invention discloses a private key generation and decryption method based on face recognition. The method comprises the following steps: performing living body analysis and counterfeit analysis onface feature data through a system; backtracking the face feature data to the date when the person creates the private key, summarizing the backtracked face feature data, and extracting an abstract; the abstract is used as a random factor to generate a key pair, and the key pair is used as a private key to decrypt the data; obtaining original data before encryption; the invention further disclosesa system for generating and decrypting the private key based on face recognition, the problems that the private key is forgotten, lost and stolen and the like are prevented by collecting the face feature data and taking the face feature data as the seed of the private key or generating the private key, and the private key does not need to be memorized and copied by hand and is safe and convenientto use. And the authenticity of the face feature data is judged by using a living body verification detector, so that face photos and counterfeit face data features are prevented from decrypting thedata, and the safety of the private key is ensured.

Description

technical field [0001] The invention belongs to the field of blockchain, and in particular relates to a method and system for generating and decrypting a private key based on face recognition. Background technique [0002] In the world of blockchain, the reliability of all data is based on cryptography, and the most widely used encryption algorithm type in blockchain is asymmetric encryption, which relies on a pair of public key and private key. The key protects information security. The public key is open to the public to verify information, while the private key is held by oneself. The privacy of the private key determines the encryption reliability of this type of encryption algorithm, and the private key is often used by a A long string of irregular uppercase and lowercase letters plus numbers of more than 128 characters is difficult for human beings to record directly by memory.

[0002] In the world of blockchain, the reliability of all data is based on cryptography, and the most widely used encryption algorithm type in blockchain is asymmetric encryption, which relies on a pair of public key and private key. The key protects information security. The public key is open to the public to verify information, while the private key is held by oneself. The privacy of the private key determines the encryption reliability of this type of encryption algorithm, and the private key is often used by a A long string of irregular uppercase and lowercase letters plus numbers of more than 128 characters is difficult for human beings to record directly by memory. They are often recorded by copying and copying to electronic memos or hand-written records on paper notepads. The loss and the theft of electronic memos make the originally safe encryption algorithm less secure; then is there a better private key management method to solve this problem? The correct way is to use letters or numbers that can be memorized by the human brain as seeds to generate a fixed pair of public keys and private keys. As long as this seed is remembered, the private key will be remembered. However, due to the offline nature of blockchain data, anyone can There are endless test passwords, so the seeds often need to be very complicated, such as a long poem, and such passwords are different from the passwords that people use every day, so that people will involuntarily choose to record them, and when they are recorded, they will be Theft of private keys due to torrent leaks
