摘要:
A biometric authentication device has high security by preventing intra-device information from being falsified and stolen by a third party. A biometric authentication device includes a biometric information storage module, a biometric information authenticating module for individual authentication, a mutual authentication module with the terminal, a registration counter corresponding to the mutual authentication, an authentication counter corresponding to the biometric authentication, a stoppage flag set when the value of the counter is larger than a predetermined value, and authentication control module for preventing the module from operating depending on the stoppage flag.
摘要:
A biometric authentication device and a terminal exhibit high security corresponding to a utilizing mode. The biometric authentication device includes a biometric information storage module performing mutual authentication with an electronic device by use of a common key, acquiring biometric information from the electronic device when validity is mutually authenticated and storing the biometric information in a biometric information storage module, and a biometric information authenticating module effecting the authentication with the electronic device by use of the public key, and authenticating, when the validity is authenticated, the biometric information stored in the biometric information storage module and the present biometric information.

A user authentication apparatus includes: means for storing biometric authentication information obtained from a user; means for communicating with a electronic equipment, which authenticates the user with the user's biometric authentication information; means for sending, in response to a first inquiry from the electronic equipment, store location definition information, which defines store locations of various output information; and output means for outputting, in response to a read request sent from the electronic equipment to designate a store location defined by the store location definition information, the output information along with identification information which indicates the type of the output information. The output means outputs, to an external device, as one of the output information, along with identification information, authentication information store location information, which describes in a given format where authentication information including the biometric authentication information is stored.
摘要:
In a biometrics authentication device which uses biometrics information to authenticate individuals, guidance is provided such that image capture of biometrics information is performed appropriately. An image capture device is caused to perform a plurality of image capture operations (including distance measurement) at short intervals. And when image capture NG occurs frequently, a control unit stacks the NG results, and if image capture NGs are not resolved even after a prescribed number of image capture operations, judges that the relation between the body part and the image capture device must be corrected, analyzes the stacked image capture NG causes, and displays a guidance screen on a display device according to the analysis result.

摘要:
To provide a technique by which an —OH group can be effectively formed on a material surface for the purpose of making the material suitable for bonding (for example, for molecular bonding) that utilizes a chemical reaction (chemical binding). [Solution] A bonding method for bonding a substrate A and a substrate B, which comprises: a step for applying an agent that contains the compound (α) described below on the surface of the substrate A; a step for arranging the substrate B so as to face the compound (α) that is present on the surface of the substrate A; and a step for integrally bonding the substrate A and the substrate B by applying a force onto the substrate A and/or the substrate B. The compound (α) is a compound that has an OH group or an OH-forming group, an azide group and a triazine ring in each molecule, and the substrate A is configured using a polymer.

The users are allowed to easily retrieve contents data such as recipe data. A personal computer (103) receives recipe data from a server (101) via a communication network (102), and stores the received recipe data in a memory card (104). The personal computer updates recipe hierarchical information (142) in the memory card (104), i.e., information which indicates classified levels of recipe data based on retrieval keys, with reference to overall hierarchical information (133), i.e., information which indicates the hierarchical relation of retrieval keys in the whole recipes, so that the newly stored recipe data is included in the recipe hierarchical information.
摘要:
An optical logic device performs a logic operation on a plurality of input light signals. The optical logic device has a photoelectric conversion portion, in which photoreceivers for receiving input light signals are provided in parallel, that outputs an electric signal obtained by adding up outputs of the photoreceivers, and a comparator that compares a voltage level of the electric signal outputted from the photoelectric conversion portion with a predetermined voltage level.
