Problems solved by technology
[0002] At present, most of the intelligent access control is based on radio frequency card technology, fingerprint technology or facial recognition technology. The radio frequency card technology must require the user to carry the door card with him, which is inconvenient and easy to lose; When there is dirt or wounds, it is not easy to identify; and facial recognition technology is expensive and difficult to popularize
With the popularization of smart phones, two-dimensional codes have gradually become a new identification method. Although the two-dimensional code identification method is convenient to use and low in cost, static two-dimensional codes are also easy to copy by taking pictures. lower sex

The embodiment of the invention discloses an access control method based on Internet of Things, an access control system and a storage medium. The method belongs to the technical field of Internet of Things, and comprises the following steps: a terminal receives a random number issued by a management server, and encrypts the random number, a current timestamp and a user ID logging in the terminal through a management public key to generate a two-dimensional code image; the access control device identifies the two-dimensional code image and signs through the access control private key to obtain a signed binary code; the management server verifies the signature binary code through the access control public key to obtain a binary code, decrypts the binary code through the management private key to obtain a random number, a user ID and a timestamp, and detects whether a preset condition is met or not; if yes, the management server signs the preset door opening instruction through the management private key to obtain a signed door opening instruction; the access control device verifies the signature door opening instruction through the management public key to obtain a preset door opening instruction so as to open the access control. According to the embodiment of the invention, the security of the access control can be improved.
Description
technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to an access control method, an access control system and a storage medium based on the Internet of Things. Background technique [0002] At present, most of the intelligent access control is based on radio frequency card technology, fingerprint technology or facial recognition technology. The radio frequency card technology must require the user to carry the door card with him, which is inconvenient and easy to lose; When there is dirt or wounds on it, it is not easy to identify; and facial recognition technology is expensive and difficult to popularize. With the popularization of smart phones, two-dimensional codes have gradually become a new identification method. Although the two-dimensional code identification method is convenient to use and low in cost, static two-dimensional codes are also easy to copy by taking pictures. Sex is lower.
