PROBLEM TO BE SOLVED: To provide a portable terminal machine capable of preventing the occurrence of unauthorized use of specific functions among a plurality of functions. SOLUTION: Fingerprint data outputted from a fingerprint detector 14 are stored in a flash ROM 22 at S1. It is decided whether the restriction of functions is instructed to the fingerprint detector 14 at S2. It is decided whether the restriction of functions is instructed on the basis of whether the same fingerprint data as the fingerprint data registered at S1 are outputted from the fingerprint detector 14. Namely, the fingerprint data, outputted from the fingerprint detector 14, are collated with the fingerprint data stored in the flash ROM 22. It is decided whether both of the data coincide with each other. It is shifted to S3 When both of the data agree with each other. When both of the data do not coincide with each other, a user waits for the output of the fingerprint data from the fingerprint detector 14. The use of functions, related to the privacy of the user of a portable telephone 1, is restricted in S3. COPYRIGHT: (C)2006,JPO&NCIPI
