Embodiment Construction

[0061]The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted here that the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute conflicts with each other.

[0062] In order to solve the problem of easy memory, the present invention adopts the idea that the private key does not need to be memorized; in order to solve the problem of discarding the private key, the idea adopted is to prevent the private key from being lost; and the characteristics of the password need to be different for everyone. The idea to solve this problem is to find something that everyone has but is not the same; the solution that combines the above two ideas to solve the problem is to use fingerprints instead of private keys, but fingerprints cannot be used as private keys, so the core of the present ...

Abstract

The invention discloses a private key generation method based on fingerprint identification. The method includes collecting and processing the fingerprint information; extracting a fingerprint ridge line of the image and calculating the curvature of the fingerprint ridge line; extracting fingerprint lines of the image and calculating the frequency of the fingerprint lines; generating fingerprint feature seed, generating a password by using the fingerprint feature seed, keeping the private key and the public key by the user, the user using the private key to encrypt data and other users using the public key to verify the encrypted dada; the invention further discloses a private key generation system based on fingerprint identification, the private key generation system comprises a fingerprint identifier, a fingerprint restorer, a fingerprint feature device and a fingerprint private key device, the effect of using the fingerprint as the private key is achieved, and the problem that the private key is forgotten and lost is solved.

Description

technical field [0001] The invention relates to the technical field of blockchain encryption, in particular to a method and system for generating a private key based on fingerprint identification. Background technique [0002] Cryptography based on mathematics has been developed for a long time, and encryption applications based on cryptography have also been widely used in social activities. The application of the most widely used asymmetric encryption algorithm is even more extensive, and the more widely used it is, the more critical it is to protect the key in its asymmetric encryption. At present, the protection of the key often uses mnemonics Or U-shield method, the first method makes the private key easy to be remembered by the human brain, and the second method makes the private key not easy to be cracked, but both of these two private keys have the problem of easy loss, such as forgetting after not using it for too long Yes, the U-shield wallet was stolen by a thief...
