Abstract

The invention discloses a method and a device for identifying a time-varying dynamic two-dimensional code entrance guard, which belong to the technical field of identifying two-dimensional code entrance guards, and aim at solving the problem of the existence of potential safety hazards in the presently-used method for identifying a static two-dimensional code entrance guard. The method comprises the following steps that the prestored personal identification information and the current time information are encrypted by a smart phone by virtue of a public key, and then the encrypted result is displayed in a two-dimensional code manner; a two-dimensional code identification device reads the displayed two-dimensional code, decrypts the read encryption information by virtue of a private key, the personal identification information and the current time information are separated, the separated information is compared with the information stored in a database and the current time respectively, and if the two parts of information is matched, then an entrance guard controller is controlled to carry out door-opening operation; and the public key and the private key are generated by the two-dimensional code identification device by an asymmetrical secret key algorithm. The method and the device are used for entrance guard identification.

Description

technical field [0001] The invention belongs to the technical field of two-dimensional code access control identification. Background technique [0002] The current access control identification system mainly includes biometrics (fingerprint, palm print, retina, etc.), RFID card and input password. These methods are relatively static and are easy to be stolen and copied. Examples include duplicated rubber fingerprints, duplicated RFID cards, stolen passwords, etc. With the popularization of smart phones, QR codes have gradually become a new identification method, but static QR codes are also easy to copy by taking pictures. These have all formed certain hidden danger to the security of access control system. Contents of the invention [0003] The purpose of the present invention is to solve the problem of potential safety hazards in the current access control identification method using a static two-dimensional code. The present invention provides a dynamic two-dimensio...
