Due to the natural characteristics of living beings, the probability of the same human fingerprint is 1 / 1000000. Considering the fingerprint recognition error, the actual single-fingerprint encryption lock can achieve a probability of 1 / 100000 for different fingerprints. Provide higher encryption levels for some special applications and needs

[0021] For the fingerprint password setting process, set the indicator light in the fingerprint combination lock to prompt the user to input the fingerprint, input the first fingerprint to be set at the fingerprint input port, after the fingerprint identification is successful, the indicator light will flash yellow to prompt Confirm, and then put the same fingerprint into the fingerprint input port. After the fingerprint recognition is successful and matched, the green indicator light will be on for a while to prompt and then continue to turn to a yellow indicator light to indicate the next fingerprint input. If the matching is inconsistent or the fingerprint setting fails, the red indicator light will be on for a long time to prompt and then continue to turn to a yellow indicator light to indicate the input of the next fingerprint. The subsequent fingerprint setting method is the same as the first fingerprint setting. After setting enough multiple fingerprints, press the OK k...

Abstract

The invention discloses a multi-fingerprint encryption method with improved encryption level, which includes a fingerprint password setting process and a fingerprint password unlocking process; the fingerprints of two or more than two different fingers are arbitrarily set as passwords in an arrangement or combination mode, and stored into the memory chip of the fingerprint lock. When unlocking, for the multi-fingerprint password in the arrangement mode, it is required to input the different fingerprints set in sequence according to the order of setting within the specified time interval as the correct decryption password. For combined multi-fingerprint passwords, it is required to input different set fingerprints in a random order within the specified time interval as the correct decryption password, that is to say, in the combined mode, only need to input all the specific fingerprint passwords. , instead of following a certain input sequence, thus realizing the requirements of different encryption levels. The method can greatly improve the encryption level of the fingerprint combination lock, and satisfies the characteristics of some special applications requiring a higher encryption level.

Description

technical field [0001] The invention relates to a multi-fingerprint encryption method with enhanced encryption level. Background technique [0002] Nowadays, fingerprint encryption locks are more and more widely used, but so far, the vast majority of fingerprint encryption locks are only single-fingerprint encryption - put the set fingerprint on the fingerprint scanning port or slide the fingerprint scanning port to complete the fingerprint scanning and identification. Due to the natural characteristics of living beings, the probability of the same human fingerprint is 1 / 1000000. Considering the factors of fingerprint recognition errors, the actual single-fingerprint encryption lock can achieve a probability of 1 / 100000 for different fingerprints. Provide higher encryption levels for some special applications and requirements. Contents of the invention [0003] The multi-fingerprint encryption method for increasing the encryption level of the present invention can greatl...
