A double-encrypted access control system based on mobile phone QR codes

Abstract

The invention discloses a double-encryption entrance guard system based on a handset two-dimension code. The system comprises an evident code encryption module (11), a secret code encryption module (12), a two-dimension code secret-code sequence module (13), an image processing module (21) and an information distinguishing module (23), wherein the evident code encryption module (11) is used for obtaining an evident code sequence (111) when a user inputs a password manually; the secret code encryption module (12) is used for generating an evident code / element-two-dimension code comparison table (123); the two-dimension code secret-code sequence module (13) is used for generating and displaying a two-dimension code sequence on a handset screen; the image processing module (21) is used for recognizing and decoding a two-dimension code image; and the information distinguishing module (23) is used for distinguishing two-dimension code content information (22). The double-encryption entrance guard system based on the handset two-dimension code adopts two codes of the evident code and the two-dimension code secret code, so that double-encryption performance is achieved, a one-to-one correspondence relation of the evident code and the secret code is set by the user and has no rule to follow, moreover, the codes are invisible after setting, so that the recognition is safer and more reliable, and the safety of the entrance guard system is improved; and the handset two-dimension code is used in the entrance guard system, therefore, the convenience of the entrance guard system is increased, and the cost of the entrance guard system is reduced.

Description

technical field [0001] The invention relates to an access control system, in particular to a double-encrypted access control system based on a mobile phone two-dimensional code. Background technique [0002] In recent years, with the improvement of people's living standards, safety awareness has gradually increased, and people have higher and higher requirements for access control systems. Access control systems are installed on many occasions to prevent security accidents. At present, there are many kinds of access control systems in China, and there are many relevant literature and patents. Here, only a few representative access control systems are listed for illustration. "Design of Wireless Access Control System Based on RFID Technology", this type of access control system unlocks the door lock through wireless communication. "Family Intelligent Access Control System Based on Face Recognition and 3G Communication" and "Smart Fingerprint Access Control System", this type...
