Authentication apparatus, authentication method, and non-transitory computer readable medium storing program

摘要

An authentication apparatus includes a detection unit that detects whether or not communication with a portable storage medium storing identification information for identifying a user is able to be performed, a reading unit that reads identification information stored in the storage medium when the detection unit detects that the communication is able to be performed, a time counting unit that counts an elapsed time, a determination unit that determines whether or not the elapsed time counted by the time counting unit matches a predefined time for the identification information read by the reading unit, and an authentication unit that authenticates the storage medium with which the detection unit detects that the communication is able to he performed when the determination unit determines that the elapsed time counted by the time counting unit matches the predefined time.

1. An authentication apparatus comprising:
a detection unit, executed by a processor, that detects whether or not communication with a portable storage medium storing identification information for identifying a user, is able to be performed; a reading unit comprising a hardware sensor that receives data from a card reader over an interface, that reads identification information stored in the portable storage medium when the detection unit detects that the portable storage medium is connected and that the communication is able to be performed; a time counting unit, executed by the processor, that counts an elapsed time that is initiated from a starting time determined when the detection unit detects that the communication with the portable storage medium is unable to be performed when the portable storage medium is disconnected to a time when the detection unit detects that the communication is able to be performed again when the portable storage medium is connected again; a determination unit, executed by the processor, that determines whether or not the elapsed time counted by the time counting unit matches a predefined time for the identification information read by the reading unit; and an authentication unit, executed by the processor, that authenticates the portable storage medium with which the detection unit detects that the communication is able to be performed and that the portable storage medium is connected when the determination unit determines that the elapsed time counted by the time counting unit matches the predefined time, wherein, upon successfully authenticating the portable storage medium, communications is performed, wherein the time counting unit counts each elapsed time for the portable storage medium with which the detection unit at least twice detects that the communication is able to be performed, and wherein the authentication unit authenticates the portable storage medium with which the detection unit detects that the communication is able to be performed when the determination unit determines that the elapsed time counted in each of the predefined number of times matches the predefined time in each of the predefined number of times.
