Provided is a structure enabling dispersion of a load that is incurred by a public key certificate issuer authority or a registration authority. The structure has an issuer authority that issues a public key certificate and registration authorities each of which receives and examines a request for issuance of a public key certificate made by an end entity, wherein the registration authorities are hierarchically structured. Each of registration authorities of a hierarchical level manages registration authorities that rank immediately below or end entities. The registration authority receives a request for issuance of a public key certificate and examines it. This means that a load each registration authority must incur for processing is dispersed. One hierarchical structure of registration authorities is formed under any of various standards which stipulates a security policy, scalability, geographical classification, functional classification, or an organization.

A user data server system includes: a data storage node, which stores user data, registers the user data in a Distributed Hash Table (DHT) network by using a key, and receives and processes user data operation requests; a DHT index node, which creates and maintains DHT routing information according to a DHT algorithm and stores information of data storage nodes where user data is stored according to the key and searches for information of a data storage node where target user data is stored according to the key; a DHT super maintenance node, which manages and optimizes the DHT network; and a front end node capable of protocol processing and service processing, which obtains a key associated with a target user and obtains information of a data storage node where the target user data is stored by querying the DHT index node via the DHT network according to the key, and performs operations on the user data stored in the data storage node where the target user data is stored. With the technical solution provided by the present invention, a user data server is not centralized and is highly scalable and highly reliable with a high cost-effectiveness.

In a personal authentication medium issuing apparatus, a main image information is input and whether a personal authentication medium on which synthesized image information having sub-information embedded in the main image information is checked or not is determined based on the state of the input main image information. Further, synthesized image information having sub-information embedded in an invisible state in the main image information which is set in a visible state is formed, a personal authentication medium is formed by printing the synthesized image information on a recording medium and the thus formed personal authentication media are sorted into personal authentication media determined to be completely formed and personal authentication media determined to require a checking process.

The present invention is a command or data transfer between two integrated circuit devices (hereafter LSIs) wherein an LSI issuing a command or data (issuing side LSI) outputs a strobe signal, which indicates that a valid command or data was transmitted, to the LSI which receives the command or data (receiving side LSI), and the receiving side LSI outputs a signal, which notifies that the command processing completed (command ready signal), to the issuing side LSI. The issuing side LSI comprises a counter where a value to indicate the number of commands which the receiving side LSI can simultaneously process or simultaneously receive is loaded at initialization, wherein the counter is decremented when a command or data is issued, the counter is incremented when the ready signal is received, and issuing a command or data is inhibited when the counter becomes “0”. Therefore the issuing side LSI can issue a command or data to the receiving side LSI without confirming a busy signal from the receiving side LSI.

Provided is a pressure sensor that includes a detection film that is arranged on a silicon substrate, detects a pressure applied to a surface thereof, and generates a protrusion deformation in response to the pressure. The pressure sensor also includes an optical transmitter and an optical detector that are arranged on the silicon substrate on opposite sides of the detection film and are located at a plane parallel to a plane comprising the detection film. The pressure sensor also includes a pressure calculation module that is connected to the optical detector and is used for acquiring light intensity data and calculating a pressure value according to the light intensity data. Also provided is a method of manufacturing the pressure sensor.
