摘要:
A CPU (11) of a personal computer (1) instructs a CPU (32) of an adapter (26) comprising a semiconductor IC to calculate the hash value of a tune database for managing the contents recorded on an HDD (21) and to store the hash value in a nonvolatile memory (34). When the contents recorded on the HDD (21) are reproduced, the CPU (11) calculates the hash value of the tune database, compares it with the hash value stored in the nonvolatile memory (34), and control the reproduction of the contents from the HDD (21) according to the results of the comparison.
摘要:
A method for, for example, integrally handling musical contents of different formats present on one personal computer while protecting the copyright of the contents. A reproduction application (A) (311) manages the musical content distributed from an EMD server (A) (4-1). A comprehensive managing unit (315) manages musical content distributed from an EMD server (X) (4-3) and transfers it to a portable device (6-3). The format of the usage rule of the musical content managed by the reproduction application (A) (311) is different from that managed by the comprehensive managing unit (315). An EMD receiving interface (316) converts the format and handles integrally contents.
摘要:
A content database (114) contains identification information for identifying a content and time information on the time when the content is copied according to the identification information. An audio recording program (113) acquires the identification information on the content to be copied and copies the content according to the acquired identification information and time information stored in the content database (114). As a result, without greatly impairing the user's interests, a mass of copies are substantially inhibited.

The present technology relates to a wearable device and an electricity supply system that make it possible to reduce the stress on a user in relation to electricity supply. A power generating unit is provided on the external world-side surface or the eyeball-side surface of a contact lens-type wearable device. The power generating unit generates electric power by chemical reaction with a substance contained in a secretion or a body fluid of a user wearing the wearable device, and a power managing unit supplies the electric power obtained in the power generating unit to each part of the wearable device. Thus, the power generating unit performs electricity generation using the secretion or the body fluid of the user as fuel; thereby, electric power can be stably supplied, and the stress on the user in relation to electricity supply can be reduced. The present technology can be applied to a contact lens-type wearable device.
摘要:
There is provided a communication terminal including an electrode unit configured to cause a dielectric to induce an electric field, and to transmit and receive signals via the dielectric, and a processing unit configured to obtain power from a reception signal received by the electrode unit, to process the reception signal, and to cause a response signal to be transmitted from the electrode unit through load modulation.
摘要:
A personal computer (1) transmits a source program to which a signature is attached to an authenticating station through a communication unit (25). The authenticating station, if no alteration is found in the received source program, encrypts the source program with a secret key of the authenticating station, and transmits the encrypted source program to the personal computer (1). The personal computer (1) records the encrypted source program on an HDD (21) and transmits it to an adapter (26).
