摘要:
An antistatic polyester film having the excellent antistatic property and improved appearance of a coating layer, and a process for producing the same are disclosed. The antistatic polyester film comprises a polyester film having formed on at least one surface thereof an antistatic coating layer obtained by coating a coating liquid containing an organic-inorganic composite conductive sol (A) comprising colloidal particles of conductive oxide, having a primary particle size of 5 to 50 nm, and colloidal particles of a conductive polymer. This antistatic polyester film has excellent antistatic property, particularly excellent antistatic property under the low humidity environment, and therefore is useful in magnetic cards, magnetic disks, printing materials, graphic materials, photosensitive materials and the like.

An information providing system for accurately providing a user with information that matches the user at a small calculating cost. The system includes a feature vector generating unit for generating a feature vector of each of a plurality of persons, and a user cluster generating unit for classifying the plurality of persons into a plurality of clusters based on the feature vector of each of the plurality of persons. The system selects at least one of the plurality of clusters based on a feature vector of a specified person, and outputs information related to the selected cluster.

A public key certificate issuing system is disclosed which comprises a certificate authority for issuing a public key certificate for an entity, the certificate authority including a plurality of signature modules each executing a different encryption algorithm and a registration authority that receives a public key certificate issuance request from the entity.
摘要:
In a communication device which can realize a protocol conversion by a single device without preparing respective packages for existing various protocols, a protocol attribute included in a packet received is detected, protocol processing order data indicating a protocol processing order based on the protocol attribute are generated, and a plurality of protocols within the received packet are processed based on the protocol processing order data.
摘要:
A person authentication system capable of performing personal authentication by comparing templates that is personal identification data with sampling information input by a user is disclosed. For example, a service provider (SP) or a user device (UD) acquires the templates from a person identification certificate (IDC) generated by a personal identification certificate authority that is a third party to thereby perform personal authentication. The IDC stores data, such as a certificate identifier and a user identifier, in accordance with a format, and also stores encrypted templates in a manner that the data can be decrypted by an entity that performs authentication. This arrangement achieves efficient template retrieval and a personal authentication process, as well as effective prevention of the templates from being leaking out.
摘要:
Disclosed are a person authentication system, a person authentication method, and an information processing apparatus which allow person authentication to be performed in an easy fashion in various devices by comparing a template serving as person identification data with sampling information input by a user. A service provider (SP) or user device (UD) executes person authentication by acquiring a template from a person identification certificate (IDC) generated by a third-party agency serving as a person identification certificate authority (IDA). The IDA acquires a template serving as identification data after verifying a person requesting an IDC to be issued, and generates the IDC storing template information. The IDA distributes the IDC having a digital signature of the IDA added thereto to the SP and the UD.
摘要:
A first mounting unit and a second mounting unit capable of performing component holding, component recognition, and component placement for two boards independently of each other are provided. A first conveyance path for loading and unloading the first board, and a second conveyance path for loading and unloading the second board, are independently arranged.
摘要:
The present invention provides a novel configuration which allows devices capable of processing different signature algorithms to mutually verify public key certificates. In this configuration, public key certificates storing plural signatures based on different signature algorithms such as RSA and ECC are issued and each device selects a signature which can be processed (namely, verified) by itself and verifies the selected signature. Consequently, the novel configuration allows the devices each being capable of verifying only a different signature algorithm to verify the public key certificates of the other devices, so that each device can perform public key certificate verification in the cross-certification and encrypted data communication not only with the other devices having public key certificates attached with signatures based on the same signature algorithm as that of each device, but also with the other devices or providers having public key certificates attached with signatures based on different signature algorithms from that of each device, thereby significantly enhancing the reliability in communication.
摘要:
A person identification certificate link system forms a link between a person identification certificate which stores a template serving as person identification data and which is generated by a person identification certificate authority and a public key certificate which stores a public key, thereby specifying one certificate based on the other certificate. With this arrangement, a cryptographic key to the template stored in the person identification certificate can be specified. It is also possible to quickly obtain a combination of the person identification certificate and the public key certificate which are both utilized in transaction with a service provider, thereby improving the processing efficiency.
