According to an embodiment, an authentication device for authenticating a user includes a biological sensor, a storage unit, a communication interface, a detection mechanism, and a processor. The biological sensor acquires biological information. The detection mechanism detects attachment/detachment. The processor authenticates a user using the biological information, and when the authentication is successful, the processor then stores authentication information in the storage unit and turns off the authentication device. When the communication interface receives a magnetic field from an external device, the processor activates the authentication device using power from the communication interface, and upon receipt of an authentication command, if the storage unit stores the authentication information, the processor transmits an authentication signal indicating that authentication is successful to the external device. When the detection mechanism detects that the authentication device is removed from the user, the processor deletes the authentication information in the storage unit.

Authentication device

An IC card system includes an IC card management server and an IC card. The IC card management server requests a SIM management server to make an inquiry regarding a user based on card identification information and user information relating to a contract of SIM card, and, in a case that validity of the user is verified, transmits a generation request for generating a registration application registering biometric authentication information, including the card identification information and the secret key, to the SIM management server. The IC card includes a data storage storing the card identification information and the secret key and storing the biometric authentication information and, in a case that authentication based on the card identification information and the secret key through communication with the SIM card based on the registration application is succeed, stores the biometric authentication information based on the biometric information in the data storage.

IC card system and information registering method

A function separation type photoconductor for use in electrophotography comprises an electroconductive substrate, a carrier generation layer vapor deposited on the substrate and a carrier transport layer formed on the carrier generation layer. The carrier generation layer is made of an indium phthalocyanine having the general formula ##STR1## wherein Me represents indium, and X is a halogen selected from the group consisting of chlorine, bromine and iodine.

Photoconductor for electrophotography comprises indium phthalocyanine

A photoconductor for electrophotography prepared by forming a carrier generation layer made from an organic photoconducting material on a conductive substrate and further forming a carrier transport layer on the carrier generation layer wherein the organic photoconducting material has a basic structure corresponding to phthalocyanine having the following general formula: ##STR1## wherein a central metal Me is selected from the group consisting of indium, gallium and aluminum, and X is a combined halogen, and the above phthalocyanine is the one in which some hydrogen of benzene rings positioned around the phthalocyanine ring of the above basic structure are substituted by the same halogen with the combined halogen, and furthermore the above organic photoconducting material may be a mixture of the former phthalocyanine and the latter phthalocyanine.
