An information processing system, such as a camera system, includes a radio communication system and an information appliance (such as a camera) communicable with the radio communication system within a predetermined distance. The information appliance includes an image pickup for obtaining image data by photographing a subject, a storing part for storing information peculiar to a user of the information appliance, a radio communication part for transmitting a predetermined radio signal and for reading information from the radio communication system, and an authorization part for authorizing the user by collating information from the radio communication system read at the radio communication part with stored information peculiar to the user. The radio communication system includes storage for storing predetermined information and a transmission part for receiving a radio signal generated at the information appliance and for transmitting the stored predetermined signal as a radio signal.

Camera system for communicating information related to user authorization and image data over a radio communication system

A digital evidential camera system is for detecting the alteration of image data obtained by photographing an object. The system comprises the camera and an alteration detection unit. The camera includes an image pickup unit for picking up an image of the object and an encryption processing unit for generating the alteration detection data using an encryption key built therein from the image data obtained by the image pickup unit. The alteration detection unit decrypts the alteration detection data using a decryption key corresponding to the encryption key, and detects whether the image data is altered based on the result of decryption.

Digital evidential camera system for generating alteration detection data using built-in encryption key

An information processing (camera) system comprises a radio communication terminal (medium) and an information appliance (camera) communicable the radio communication terminal (medium) within a predetermined distance. The information appliance (camera) comprises (an image pickup part for obtaining image data by photographing a subject,) a storing part for storing information peculiar to a user of the information appliance (camera), a radio communication part (medium reading part) (transmitting a predetermined radio signal and) reading information from the radio communication terminal (medium), and an authorization part for authorizing the information appliance (camera) user by collating information from the radio communication terminal read at the radio communication part (medium reading part) with information peculiar to the information appliance (camera) user stored in the storing part (and a record part for recording the information related to the camera user authorized at the authorization part while relating the information related to the camera user authorized at the authorization part to the image data photographed at the image pickup part). The radio communication terminal (medium) comprises a storing part for storing predetermined information and a transmission part for receiving a radio signal generated at the information appliance (the predetermined radio signal generated at a radio communication medium reading part of the camera) and transmitting the predetermined signal stored in the storing part as a radio signal.

Information processing system and camera system

A digital data recording and reproducing system comprises a data input part and a data output part. Input data is manipulated through a computer system unit. The computer system unit comprises at least one of: a data retention part to store the digital data, a personal identification part to verify whether a user operating the digital data recording and reproducing system is authorized or not, an access log recording part to record that the user has accessed the data retention part, a falsification detection part to detect whether data stored in the data retention part is falsified or not, and a history data recording part to record information on changes or corrections in the data retention part. The computer system unit further comprises a control part which controls parts by giving operation instructions to the parts which the computer system unit comprises as the component parts, the parts including at least one of the data retention part, the personal identification part, the access log recording part, the falsification detection part, the history data recording part, the attribute control part and an execution decision part.
