PROBLEM TO BE SOLVED: To provide a security device configured to improve authentication reliability through simple processing.SOLUTION: A security device 1 executes selection determination processing one or more times. In the selection determination processing of a predetermined number of times or more, only when a driver selects a correct answer so that the time elapsed from when a plurality of options are output to when a selected one is received is equal to or less than a threshold, vehicle operation restriction is released, thereby improving authentication reliability. There is no need to improve analysis accuracy, as a security device for face authentication, thereby enabling simple authentication processing.SELECTED DRAWING: Figure 4 |
