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 sales apparatus for selling content to a purchaser wearing a communication terminal is provided. The apparatus includes a content selection section allowing selection of content for sale; a communication section built in the content selection section for communicating with the communication terminal; a detection section detecting a selection operation of the purchaser pressing the content selection section; an identifying section identifying content selected by the purchaser based on a detection result; a settlement section executing a settlement process for the content identified by the identifying section, with the communication terminal via the communication section and the human body of the purchaser who is depressing the content selection section; and a supply section adapted to supply the communication terminal with data of the content identified by the identifying section, via the communication section and the human body of the purchaser who is depressing the content selection section.

A user who is purchasing the same content again can buy it at a discount price. “Accounting History” of accounting information B prepared when the content is repurchased is set to ‘Discount Price.’ Since accounts are settled based on the accounting information with “Accounting History” set to ‘Discount Price,’ the user who is purchasing the same content again can buy it at a discount price.

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.

Content data encrypted with a content key, the content key encrypted with an individual key specific to an information sending device, and the individual key encrypted with a distribution key that is updated in a predetermined cycle, and supplied are sent to an information receiving device, and the information receiving device decrypts the individual key with the distribution key, decrypts the content key with the individual key, and decrypts the content data with the content key. Thus, the information sending device does not have the distribution key, and accordingly piracy of content data can be prevented with a simple configuration. Also, the information receiving device sends the content key and a playback command to other apparatuses. Thus, other apparatuses can play back contents using the playback command and the content key. Furthermore, the information sending device decrypts the content key with the distribution key before being updated, and stores the same. Thus, contents purchased by an advance order can be actually purchased regardless of expiration dates of the distribution key. Furthermore, usage right is passed from a first information receiving device to a second information receiving device different in registration information at the tome of using contents. Thus, contents can be used among information receiving devices different from each other in registration information.

A first information processing unit 100 stores identification information into a storage module 152, stores an encrypted contents signal into a mass storage unit 180, and supplies the encrypted contents signal and identification information to a second information processing unit 200 through a communication section 110. In a receiving unit 170 of the first information processing unit 100, log information generated by a purchase processing module 153 is stored into the storage module 152 every time the contents key is decoded, and the log information is transmitted at predetermined timing to a key management center 30 through the transmission section 110. The second information processing unit 200 receives the encrypted contents signal and the identification information through a communication section 210, and causes a contents processing section 260 to decode the encrypted contents signal and to append the identification information thereto.
摘要:
A detecting section which detects a carrier wave near the receiving section, a switching control section which controls a switching section so as to, when the detecting section detects the carrier wave, switch connecting destination of the first storage section into the receiving section, and when the detecting section does not detect the carrier wave, switch the connecting destination of the first storage section into the reading section, a second storage section which stores the data conversion information read by the reading section, and a display control section which converts the read display data using the data conversion information stored in the second storage section so as to display the information on the display section are provided.

There is provided an information processing apparatus including a travelable information display unit that displays before a discharge, regarding motor-driven movable bodies of a discharge source and a discharge destination driven by using electric power of batteries, information about places to which the motor-driven movable body of the discharge source can move using electric power of the battery left after the discharge by assuming, when information about a discharge amount discharged from the battery of the motor-driven movable body of the discharge source toward the motor-driven movable body of the discharge destination that receives power supply is input, a case in which the discharge amount is discharged from the battery.

An information processing method includes the steps of: detecting a magnetic field variation that occurs in the vicinity of a receiving section that receives a magnetic field signal; determining whether or not a detection result satisfies a predetermined condition that is set in advance; connecting a storage section, which stores information included in the magnetic field signal received by the receiving section, to the receiving section if it is determined that the detection result does not satisfy the condition; and connecting the storage section to a reading section that reads information stored on the storage section, if it is determined that the detection result satisfies the condition.
