Document Type and Number:
Japanese Patent JP4508334
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a capture information ciphering device capable of preventing capture information from being used deviated from an individual using range by restricting using of capture information to using by the same user or using by the same device and to provide an information capture corresponding device, a capture information ciphering method and a storage medium. SOLUTION: The device are provided with an attaching and detaching memory unit 606, an IC card interface 609 and a control CPU 602 for performing control for generating a common key for ciphering capture object information and ciphering capture object information by using a common key, control for ciphering the common key itself used for ciphering capture object information by using user characteristic information as the common key, and control for deciphering the common key itself used for ciphering capture object information and deciphering stored capture information of a memory module 200 by using the deciphered common key.
