The present invention provides an information processing device includes: a biometrics device, an interface control unit for controlling the biometrics device, a first storage unit for concealing a user identifier and user authentication information, a second storage unit for storing a program executed by the information processing device, and a processor for releasing the concealment of the first storage unit based on the program stored in the second storage unit and acquiring biometrics information inputted from the biometrics device, so as to compare it with the user authentication information. Thus, it is possible to prevent lowering of user-friendliness and increase of the cost when using an external authentication device in a laptop type personal computer and to provide an authentication control configuration and an authentication procedure optimal for an information processing device such as a laptop type personal computer.
