摘要:
A communications system having a communications apparatus that performs communications with another communications apparatus via a communications medium; said communications apparatus includes: identification information request response means that performs a response process of transmitting identification information of said communications apparatus to said other communications apparatus in response to a request, which is transmitted from said other communications apparatus, for said identification information; application processing means that performs communications with said other communications apparatus to which said identification information is transmitted through said identification information request response means, and that performs a process related to a predetermined application; and studying means that studies, with respect to a predetermined condition, success/failure tendencies of said process related to said application performed by said application processing means; wherein said identification information request response means controls, based on a study result by said studying means, output of said identification information in response to said request.
摘要:
A communication system equipped with a communication apparatus for transmitting a transmission signal to another communication apparatus via a communication medium, includes: transmission means for transmitting the transmission signal to the other communication apparatus via the communication medium; detection means for detecting a propagation signal propagated through the communication medium each time a predetermined amount of the transmission signal is transmitted from the transmission means; signal collision judgment means for judging from the propagation signal detected by the detection means whether a signal collision occurs on the communication medium between the transmission signal transmitted from the transmission means and another signal transmitted from the other communication apparatus; and control means for controlling transmission of the transmission signal from the transmission means in accordance with a judgment result by the signal collision judgment means.
摘要:
A communication system for communicating, by use of a dielectric material including a human body as a communication medium, with a communication terminal worn on said communication medium, includes: a plurality of communication means, disposed in contact with or in proximity of said communication medium, for communicating with said communication terminal via said communication medium in contact with or in proximity thereof, detection means for detecting reception levels of a signal transmitted from said communication terminal and received via the plurality of said communication means; association means, by comparing respective reception levels of a signal transmitted from a same communication terminal and received via different ones of the plurality of said communication means, for associating said communication terminal having transmitted said signal with one of the plurality of said communication means, on the basis of a result of the comparison.
摘要:
An information processing apparatus, an information processing method, and an information providing medium are provided. Encrypted information, an encrypted first key for decrypting the encrypted information, and a second key for decrypting the first key are processed to store the information in a storage medium. To be more specific, cross certification is executed with the storage medium, the first key is decrypted by the second key, the decrypted first key is encrypted, and the decrypted first key and the encrypted information are stored in the storage medium. The novel constitution prevents unauthorized replication of information by use of a low-cost, general-purpose semiconductor memory.
摘要:
Disclosed are an information processing apparatus and an information processing method which execute person authentication and allows various services such as receiving of contents to be received, provided that the authentication is successfully passed. In the information processing apparatus for executing, by a connection to an external server providing various services such as contents transmission, a process such as receiving of contents, person authentication is executed by comparing a template acquired from a person identification certificate storing a template which is person identification data of a user using the information processing apparatus with sampling information input by the user, and a connection to the external server is executed provided that the authentication is successfully passed. In addition, the person identification certificate and the public key certificate are stored in a memory together with link information in which the person identification certificate and the public key certificate applied during a process of establishing a connection to the server are related to each other.
摘要:
In a public key certificate using system, a template which serves as person identification data of a person requesting a public key certificate is obtained from a person identification certificate of the person, a person authentication is executed by comparing sampling information of the person against the template, and a public key certificate for the person is issued by a certificate authority on condition that the person authentication is established, thus reducing the load on the certificate authority for person authentication. The public key certificate issued to the user is deleted upon completion of a processing session involving use of the public key certificate, restricting the use of the public key certificate to the particular processing session.
摘要:
A person authentication system, a person authentication method, an information processing apparatus, and a program providing medium authenticate a person who uses an information apparatus in data communication. A person authentication certificate storing a template which includes person authentication data is used in the person authentication system. A person authentication execution entity checks the validity of the certificate on the basis of a certificate expiration date, a certificate usage number limit, or a template expiration date in person authentication processing on the basis of the certificate. The person authentication is executed by comparing the template with sampling information input by a user if the validity is confirmed. A person identification certificate authority updates the certificate or the template according to the request of the entity or the authenticated person.
摘要:
A content distribution is performed by a secure container including a content encrypted by a content key and container information set for a content transaction. The container information includes a person identification certificate identifiers list. Usage control status information including the list is generated and stored in a device during a secondary distribution among user devices after a primary distribution of the content. In the distribution among the user devices, identifying an identification certificate in reference to the list and performing a person authentication based on the identification certificate allows each of the user devices to use the transmitted content, when the authentication is affirmative.
