A dynamic encryption system for computer keyboard

Abstract

The invention relates to the technical field of dynamic encryption of computer keyboards. The invention relates to a dynamic encryption system for a computer keyboard. Keyboard, an LED display screen,input keys and a fingerprint collection panel are fixedly arranged on the keyboard. The keyboard comprises a power supply module, a display module and a dynamic password generator; the fingerprint collection panel comprises a fingerprint collection module, a fingerprint recognition module, a processing module and a fingerprint storage module. The dynamic password generator comprises a password generation module, a password input module and a password verification module; according to the invention, the collection module controls the image sensor to acquire fingertip images; when the fingertipfingerprint image is obtained and identity recognition is carried out by combining the fingertip fingerprint image and the pulse waveform image, the fingerprint recognition system can provide the fingerprint image, living body monitoring of fingerprint recognition is achieved, uniqueness is achieved, the safety of dynamic encryption is improved, and the expansibility and reliability of the fingerprint recognition system are improved.

Description

technical field [0001] The invention relates to the technical field of dynamic encryption of computer keyboards, in particular to a dynamic encryption system for computer keyboards. 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. The existing dynamic password lock usually sets a radio frequency transmitting circuit and an encoding circuit at the transmitting end, and sets a radio frequency receiving circuit and a decoding circuit at the receiving end to realize the generation, sending and receiving of a dynamic password. The set password has a high repetition rate, is prone to simple and fixed phenomena, and is extremely easy to b...

Problems solved by technology

When using a computer, the keyboard is a necessary input tool and an input device for controlling human-computer interaction display. It is composed of many function keys and can also be used to control the work of the program. The existing computer keyboard can only be encrypted when it is encrypted. Rely on keys to form a static string password, and the string password is easy to be stolen and cannot generate a dynamic password, so the security is not high, it is easy to cause password leakage, and the encryption function of the computer keyboard is reduced. Therefore, there is a lack of fingerprint authentication. Reliable dynamic encryption passwords to protect the privacy of people's work and life
