Abstract

An unauthorized use prevention apparatus of an information processing device is disclosed. When the information processing device starts, an arbitrary password is generated and a user is notified of the generated password. The user sounds out the password to enter a voice signal of the generated password. The voice signal of the password is verified with respect to both speech feature and password itself to determine whether an unauthorized person uses the information processing device.

Description

technical field [0001] The present invention relates to an information processing device with voice input and processing functions, and in particular to a technique for preventing unauthorized use of the information processing device. Background technique [0002] Utilizing higher-performance microprocessors, information processing equipment tends to be multifunctional. For example, personal information management functions such as address books can be provided to almost all portable communication devices such as portable telephone devices and PDA (Personal Digital Assistant) devices. In addition, through a portable communication device or a personal computer connected to the Internet, users can obtain fee-based services. [0003] When such a portable communication device falls into the hands of an unauthorized person, the unauthorized person can easily access not only important personal information of an authorized user but also paid services. Therefore, several security ...
