The invention relates to a
security management and control method and
system for a mobile terminal of a visitor in a secret-related area and a medium, and the
security management and control method comprises the steps: obtaining visitor identity information inputted by the mobile terminal, and generating a
session ID and a first dynamic two-dimensional code; in response to the reading of the code scanning
verification device on the first dynamic two-dimensional code, the
server verifies the legality of the
session ID, and issues a preset management and control strategy after the
verification is passed; when the mobile terminal is in the controlled state, monitoring violation operation violating the control strategy and generating a violation log containing violation operation information; generating a second dynamic two-dimensional code in response to a leaving instruction of the mobile terminal; in response to the reading of the code scanning
verification device on the second dynamic two-dimensional code, triggering the mobile terminal to upload the violation log to the
server; and after confirming that the
summary information is consistent with the data of the violation log, the
server sends a control releasing instruction to the mobile terminal, so that the mobile terminal is recovered to a
normal state. According to the invention, the information protection capability of the secret-related place is improved.
