Abstract
The biological information acquisition means acquires biological information of the user. The determination means determines whether a predetermined condition is satisfied. In a case in which it is determined that the predetermined condition is satisfied, the key information transmission means transmits the key information to the mobile device. An authentication means authenticates the user by using the acquired biological information, encrypted biological information for collation, and the key information received by the key information reception means from the user device.
Claims17
An authentication system comprising:
- a user device;
- and a mobile device, wherein
- the user device comprises a first memory storing first instructions and a first processor configured to execute the first instructions to:
- determine whether a predetermined condition is satisfied, and
- transmit key information in a case in which it is determined that the predetermined condition is satisfied, and
- the mobile device comprises a second memory storing second instructions and a second processor configured to execute the second instructions to:
- acquire biological information of a user,
- receive the key information transmitted from the user device,
- transmit position information of the user whose biological information is acquired to the user device, and
- authenticate the user by using the acquired biological information, encrypted biological information for collation, and the key information, and wherein
- the first processor is configured to execute the first instructions to determine whether the predetermined condition is satisfied by using the position information of the user transmitted from the mobile device.
A user device comprising:
- a memory storing instructions;
- and
- a processor configured to execute the instructions to:
- receive, from a mobile device configured to authenticate a user by using biological information of the user, encrypted biological information for collation, and the key information to the user device, position information of the user whose biological information is acquired;
- determine whether a predetermined condition is satisfied by using the position information of the user transmitted from the mobile device;
- and
- transmit key information to the mobile device in a case in which it is determined that the predetermined condition is satisfied.
A key information transmission method comprising:
- receiving, from a mobile device configured to authenticate a user by using biological information of the user, encrypted biological information for collation, and the key information to the user device, position information of the user whose biological information is acquired;
- determining whether a predetermined condition is satisfied by using the position information of the user transmitted from the mobile device;
- and
- transmitting key information to the mobile device in a case in which it is determined that the predetermined condition is satisfied.
