Abstract: A fingerprint identification system comprising: an IC card having a tamper-resistance; and a reader/writer having a tamper-resistance for reading/writing information from/into the IC card. In the reader/writer, a fingerprint image, as read by a fingerprint input unit, is preprocessed in a preprocessing unit, and extracted intermediate information is transmitted to the IC card. This IC card compares the intermediate information with the fingerprint information, and makes authentication information usable for an electronic authentication upon matching. By this electronic authentication with applications, the fingerprint identification system, which has a high level of safety and can reduce the cost is provided.

Abstract: An apparatus for transferring data between a memory and an input/output device via a serial data transfer line including a central channel unit for sending to the input/output device a chaining instruction for chaining data stored at a plurality of locations in the memory, a remote channel unit for requesting from the central channel unit a new command causing the transfer of any succeeding data, and a unit for informing a data processing unit of an amount of data which has not been transferred from the memory to the input/output device.

Abstract: In a loop network system in which a plurality of nodes are connected in the form of a loop, and a token frame is transmitted to shift the data transmit right among the nodes, the token frame transmitted from a node includes information for reserving the data transmit right of its own node even after allocation of the data transmit right to another node, so that a full duplex communication linkage can be established between the node having acquired the data transmit right by receiving the token frame and the node having transmitted the token frame. The token frame further includes a level mask field specifying the data transmit right allocation level so that the data transmit right is shifted according to the allocation level.

Abstract: A data searching apparatus has a storage unit for storing a record having a plurality of fields, a first register for setting a compare condition and compare data for the fields, a compare circuit for comparing the fields of the record transferred from the storage unit with the compare data in accordance with the compare condition, a logical operation circuit for logically operating on the compare results of the compare circuit to check if the fields meet the compare condition, a buffer memory for storing the content of the record, a second register for setting attributes of the fields of the record, and control circuit for writing only those fields of the record which are determined by the logical operation circuit to meet the compare condition into the buffer memory in accordance with the attributes of the fields.
