To provide an authentication technology acquiring high security with a simple configuration. In an information processing device utilizing a user's input operation for authentication, an input frame is displayed to the user, the user is prompted to input a keyword to within the input frame, a magnitude of the input by the user is judged, and the inputted keyword is judged, results of the judgments are used as authentication information for the authentication. A magnitude of the input may be a size of the input frame and a size of a character, which are designated by the user.

Authentication method

An information processing apparatus with programmable function and self-repair function which can deal with multiple troubles the information processing apparatus includes a logic processing unit formed of logic forming elements for realizing a predetermined function; spare logic processing units that can be reconfigured of logic forming elements to reproduce the predetermined function of the logic processing unit; a data holding unit for holding forming data in the logic processing unit; a fault detecting unit for detecting a fault occurrence in the logic processing unit; and a reconfiguring unit for reconfiguring the spare logic processing unit having a logic circuit configuration similar to the logic processing unit, based on configuration data read out of the data holding unit, when the fault detecting unit detects a fault occurrence. The information processing apparatus can automatically reconfigure the system to reproduce its original normal function of a faulty forming element.
