Embodiment Construction
[0061]The present invention will be described in further 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 there is no conflict 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 that the private key cannot be 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 different; the solution that combines the above two problem-solving ideas is to use fingerprints instead of private keys, but fingerprints cannot be used as private keys, so the core of the present invention is Yes, use the ...

The invention discloses a private key generation method based on fingerprint identification. By collecting and processing fingerprint information, extracting the fingerprint ridge line of an image and calculating the curvature of the fingerprint ridge line, extracting the fingerprint line of the image and calculating the fingerprint ridge line The frequency of the line, generate the fingerprint feature seed, use the fingerprint feature seed to generate a password, the user keeps the private key, discloses the public key, the user uses the private key to encrypt data, other users use the public key to verify the encrypted data, the present invention also A private key generation system based on fingerprint identification is disclosed, including a fingerprint recognizer, a fingerprint restorer, a fingerprint feature device, and a fingerprint private key device. missing problem.
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 encryption. At present, the protection of the key often uses a mnemonic Or the U-shield way, the first way makes the private key easy for the human brain to remember, and the second way makes the private key not easy to be cracked, but both private keys have the problem of easy loss, such as forgetting if they are not used for too long. Now, the U-shield wallet was stolen by a thief. The ...
