摘要:
To provide an improved management structure of memory devices storing service-use applications. A card for a memory device applied to use various services is provided as one child card or more corresponding to each of the services, a parent card-stores data for child-card issue management, and the child-card issue processing is executed based on the parent card, such as parent card authentication. An issue certificate having a parent-card digital signature is stored in the child card, the issue certificate contains a service code and a child-card identification, and thus it becomes possible to confirm a service set in the child card based on the issue certificate as the parent-card signature data.

摘要:
In authentication using a plurality of cipher keys, the authentication time is shortened. In the case that an encipher key to encipher key are required to take an access to each area out of the area to area in a memory of an IC card, a plurality of areas to have an access is informed to the IC card from a reader writer, a plurality of cipher keys corresponding to these areas (for example, cipher key 1, cipher key 2, and cipher key 4) is read out, and reduction processing section generates one reduction key from these cipher keys. A random number which is generated from a random number generation section of the reader writer is transferred to the IC card, and an encipherment section enciphers the random number using the reduction key. The reader writer receives the enciphered random number from the IC card, and deciphers it using the reduction key, and judges the IC card to be proper if the deciphered random number is equal to the generated random number.

A true person can be verified with ease and a high degree of reliability. An ATM communicates with a server installed in a data center to carry out a true-person verification such as an organism authentication on the basis of an operation carried out by a user prior to a transaction process to be carried out on an account assigned to the user. When the user touches a predetermined contact area provided on an operation panel of the ATM, the ATM communicates with a portable device attached to the body of the user by using the body of the user as a communication medium. The transaction process is carried out only if the true-person verification such as an organism authentication is successful and a communication with the portable device can be performed.
摘要:
A user operates a selection panel installed in a shop to select contents which the user wants to review. A reception unit identifies the contents based on the user's operation on the selection panel, acquires an ID of a portable device incorporated in headphones worn by the user, and transmits the ID to a management server. The management server transmits data of the contents to a transmission device, which searches for a signal electrode capable of communicating with the portable device of the user among signal electrodes that are embedded in the floor of the shop. The transmission device transmits a signal representative of the contents from the signal electrode that has been searched for, and the portable device receives the signal transmitted from the transmission device. An audio signal of the contents is output from the headphones.
摘要:
A communication system for communicating with a communication terminal located on a communication medium. The system includes a plurality of communicators, disposed in contact with or in proximity to the communication medium, for communicating with the communication terminal via the communication medium, a detector for detecting reception levels of a signal transmitted from the communication terminal and received via the plurality of communicators, and an associator for associating the communication terminal with one of the plurality of communicators by comparing reception levels of the signal transmitted and received by each of the communicators.

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:
The present invention relates to a device and a method for communication, and a program that makes it possible to provide a communication environment not limited by a use environment. An electrode controlling unit 261 in a transmitting device 260 checks a state of capacitive coupling of each of an electrode 271 and an electrode 272 in an electrode unit 262 with surroundings, controls connection of each electrode to a transmitting unit 263 according to a result of the check, and makes the electrode 271 and the electrode 272 function as a transmission signal electrode or a transmission reference electrode, the transmission signal electrode and the transmission reference electrode being different from each other. The transmitting unit 263 connects the electrode 271 and the electrode 272 to an amplifying unit under control of the electrode controlling unit 261, and transmits a signal to a communication medium 280 via one of the electrodes. The present invention is applicable to communication systems.
