Embodiment 1

[0028] Such as figure 1 Shown is a flow chart of a method for verifying an access control password shown in an exemplary embodiment of the present invention, and the access control method includes the following steps:

[0029] Step S101, the access control system sets the first password and the encryption algorithm for encrypting the first password, and sends the first password and the encryption algorithm to the mobile terminal used by the user for access control verification, the first password Password cannot be changed.

[0030] In the embodiment of the present invention, the access control system is provided with a first password and an encryption algorithm for encrypting the first password. The first password is an unchangeable password. After being set in the access control system, unless the access control system is restarted, Otherwise, it is not allowed to be changed. The first password and encryption algorithm can be manually set by the user, or can be reset by the...

Embodiment 2

[0044] Such as figure 2 Shown is a structural diagram of a system for verifying access control passwords shown in an exemplary embodiment of the present invention. For ease of description, only the parts relevant to this embodiment are shown, including:

[0045] The access control system 201 is used to set the first password and the encryption algorithm for encrypting the first password, and send the first password and the encryption algorithm to the user's mobile terminal 202 for access verification, through the The encryption algorithm encrypts the first password into a second password, receives the third password sent by the mobile terminal 202, and compares the third password with the second password: if they are the same, the verification is passed; if they are different, Then the verification fails, and the first password is an unchangeable password;

[0046] At least one mobile terminal 202 is used to receive the first password and encryption algorithm sent by the acc...

Abstract

The present invention provides a method and system for verifying access control password. The method includes: setting a first password of an access control system and an encryption algorithm for encrypting the first password, sending the first password and the encryption algorithm to a mobile terminal of a user for access control authentication, wherein the first password cannot be changed password encryption algorithm; encrypting the first password into a second password by the access control system through the encryption algorithm; encrypting the first password into a third password by the mobile terminal using the encryption algorithm, and sending the third password to the access control system, wherein the access control system and the mobile terminal conduct encryption based on the same timeline; and comparing the third password and the second password by the access control system: if the passwords are the same, verification succeeds; if the passwords are different, the verification fails. The embodiment of the invention can ensure the real-time change and security of the password when the control system and the mobile terminal are not connected with the Internet.

Description

technical field [0001] The invention relates to the field of control, in particular to a method and system for verifying access control passwords. Background technique [0002] The access control system has been applied on a large scale throughout the country, and generally consists of an access control management system, an access control verification unit, and an identity password unit. [0003] The access control management system records the identity password, and the identity password that needs to be verified must first be recorded in the access control management system, such as RFID card number, fingerprint collection, or face recognition data, all need to first collect the data to the access control management system, use the database way to save. [0004] The access control verification unit checks the saved data in the database when verifying the identity password. If it exists in the database, the verification is passed. If not, it is considered that the verific...
