Abstract

The invention discloses a dynamic password lock. The dynamic password lock is provided with a fingerprint recognition module, an image processing module, a controller module, a dynamic password generation module and a wireless transmission module. According to the dynamic password lock, fingerprints with uniqueness are adopted as triggering factors to obtain dynamic passwords; existing chaos technologies and rolling technologies are adopted to generate non-repetitive and encrypted dynamic passwords; the dynamic passwords are transmitted to a user end through the wireless transmission module; after the dynamic passwords are decrypted at the user end, the dynamic passwords can be inputted, and the dynamic password lock can be unlocked; and therefore, confidentiality can be strengthened from the aspects of triggering factors, password generation and password obtaining modes, and a safety coefficient can be improved; a password input module is additionally adopted, so that conveniences can be provided for the input of the dynamic passwords for a user; an alarm module is additionally adopted, when abnormal input of the dynamic passwords occurs, alarms are rendered at an accident site, and alarm information is transmitted to the user end, and therefore, the safety coefficient can be further improved.

Description

technical field [0001] The invention relates to the security field, in particular to a dynamic combination lock. Background technique [0002] Dynamic password locks are widely used in access control, safes, ATM machines, etc. With the increasing security awareness of users, users have higher requirements for the confidentiality of dynamic passwords. Factors that affect the safety factor of the dynamic combination lock include trigger factors, password generation methods, and password acquisition methods. Existing dynamic combination lock usually has remote control type and two-dimensional code type; Remote control type dynamic combination lock is usually provided with radio frequency transmission circuit and encoding circuit at the transmitting end, and radio frequency receiving circuit and decoding circuit are set at the receiving end, realizes the generation of dynamic password, The disadvantage of sending and receiving is that the password is set by the user. The artifi...
