Problems solved by technology

[0006] However, the authentication process in the conventional information processing device or system independently implements time authentication, identity authentication, and device authentication using electronic signature technology, and there is a problem that "when", "who" and "from which device" cannot be safely performed. Composite authentication problem
Therefore, it is very difficult to build a system that provides the services required for composite authentication, and the current situation is that the provision of such services cannot be realized.

Embodiment 1

[0039] First, the outline and features of the information processing device of the first embodiment will be described. figure 1 It is a diagram for explaining the outline and features of the information processing device according to the present embodiment. As shown in the figure, the information processing device 100 incorporates a security chip (for example, an LSI with a biometric authentication function disclosed in International Publication No. 2005 / 106620 pamphlet) 10 inside the information processing device 100 . This security chip 10 executes addition and encryption of an electronic signature independently of a CPU (Central Processing Unit) 20 in the information processing device 100 .

[0040] Specifically, the security chip 10 combines the user's biological information (information such as fingerprints, irises, veins, and faces) and information on a key for generating the user's electronic signature (hereinafter referred to as the user's electronic signature key). C...

Embodiment 2

[0077] Next, the outline and features of the information processing device according to the second embodiment will be described. Figure 9 is a diagram for explaining the outline and features of the information processing device according to the second embodiment. As shown in the figure, in the information processing device 400 , a security chip (for example, an LSI having a biometric authentication function disclosed in International Publication No. 2005 / 106620) 410 is mounted on the information processing device 400 . The security chip 410 generates an electronic signature related to the user and the device (the security chip 410 ) independently of the CPU 20 in the information processing device 400 .

[0078] Specifically, the security chip 410 correspondingly stores the information of the user's biometric information and the key (hereinafter referred to as the user's electronic signature key) used to generate the user's electronic signature in a security register (which ca...

Abstract

In an information processor (100), a security chip (10) associates the biometric information (information such as fingerprint, iris, vein, or face) of a user with the information of a user electronic signature key for creating an electronic signature of the user and stores it in a user electronic signature key storage section (12), searches, when the biometric information of the user is acquired from a bio-sensor (30), a key for creating an electronic signature corresponding to the biometric information acquired by a cipher / signature processing section (18), attaches the electronic signature of the user to user created information using the searched key, encrypts the user-created information by a cipher key unique to a security chip (10), and transmits it to the destination.

Description

technical field [0001] The present invention relates to an information processing device and the like having a chip mounted in the information processing device and independently executing predetermined processing, and more particularly to an information processing device and an information management method capable of securely performing complex authentication. Background technique [0002] In recent years, the Internet has spread widely, and a large number of information processing devices are connected to such a communication network of the Internet to transmit and receive information. However, as the number of information processing devices connected to such a communication network increases, there is a problem that the security of the information processing devices themselves and the reliability of information transmitted and received between the information processing devices are reduced. [0003] Therefore, in order to improve the security of such an information proce...
