Abstract: A content provider 101 distributes a secure container 104 storing content data encrypted using content key data, content key data encrypted using distribution key data, and encrypted usage control policy data indicating the handling of the content data to a SAM 1051 of a user home network 103 etc. The SAM 1051 etc. decrypts the content data and usage control policy data stored in the secure container 104 and determines the purchase mode and usage mode and other handling of the content data based on said decrypted usage control policy data.

Abstract: A content receiver is compatible with a plurality of rights management and protection methods (RMP) devised for each content distribution system. Only the format which specifies the specification of the RMP formed of information such as content billing, security, and copyright protection, is standardized. Each content provider inputs encrypted content and rights processing information to content in a form conforming to the standardized specification. For content users, by merely being provided with functions corresponding to each RMP method in advance, even if the content is based on any RMP method, the content can be decrypted and used in the same content receiver.

Abstract: An information signal reproducing apparatus for reproducing an information signal from a recording medium on which the information signal, including added copy control information is recorded, comprising a first detector for detecting whether the information signal read out from said recording medium is encrypted or not-encrypted and for producing an output representative thereof; a second detector for detecting said copy control information from the information signal read out from the recording medium and for producing an output representative thereof; and a controller for selectively restricting reproduction of the information signal based on the outposts of the first detector and the second detector.

Abstract: A calculator system for performing duplication of contents does not necessarily perform screening, i.e., electronic watermark detection, rather, contents copy control information can be obtained otherwise. For example, in the event of copying a CD regarding which it is known beforehand that there is no electronic watermark inserted in the contents, the electronic watermark detection processing itself can be skipped as long as the CD can be confirmed to be such, thereby reducing the amount of time necessary for copying. Electronic watermark inspecting processing with heavy computation loads is performed vicariously for judging whether or not duplication of contents is permissible.

Abstract: A contents provider stores contents data in a container in a format which can only be decoded with a key distributed from an EMD service center, and transmits the container to a service provider. The service provider adds pricing information and the like and distributes this to a user home network. The user home network pays charges to the EMD service center based on the pricing information, receives the key, and decodes the contents data. Information regarding the number of times which copying is permitted is contained in the secure container, and the number of times permitted is increased each time charges are paid, thereby enabling copying to other media and the like. It is impossible to make copies from a container simply copied, or in cases where in the number of permitted times of copies has been used up. Thus, contents data can be distributed in a format wherein copying of contents data can be controlled including the number of copies made.

Abstract: It is requested to deliver items by concealing private information about a sender and a recipient without installing a database for storing information which requires strict management. A recipient's terminal apparatus obtains a delivery agency's public key from a delivery agent server apparatus. An encryption program of the delivery agency is downloaded in advance and uses the public key to encrypt recipient information containing at least recipient's private information needed for delivery of items. The recipient's encryption information is transmitted to a sender's terminal apparatus. The sender's terminal apparatus outputs the recipient's encryption information to be attached to an item entrusted to the delivery agency. A cryptogram reader of the delivery agency decrypts the output recipient's encryption information using the delivery agency's secret key. The delivery agency obtains the information about delivery destination of the recipient.

The data processing apparatus includes a coding section for coding the data, a detection section for detecting the additional data from the data, a processing section for processing the coded data coded by the coding section, and a control section for controlling operation of the processing section in response to the additional data detected by the detection section. The coding section controls an output thereof in response to the additional data detected by the detection section, and accessing to the additional data used to control the coding section is inhibited.

Abstract: A personal identification apparatus is disclosed by which personal identification can be performed making use of an impulse response obtained from a pulse signal transmitted by a living organism. A pulse generation section generates a pulse, and a speaker applies the pulse amplified by an amplifier to a finger of a user touching with the speaker and a microphone. The pulse signal is transmitted to the microphone with an attenuation characteristic that depends upon, for example, a transmission distance that depends upon the length and the thickness of the finger and characteristics of the living organism such as the thickness of the flesh and the bone density. A data synthesis processing section synthesizes the pulse and an impulse received by the microphone and amplified by an amplifier. A template recording section records a template to be used as a reference of discrimination in an authentication process together with a user ID and so forth.

The SAM serves as a slave for a host CPU, and is also provided with a common memory shared with the host CPU.

Abstract: A signal reproducing method and apparatus in which the generation limitation information, such as a token or a ticket, contained in digital data, is recorded in analog signals. A reproducing device 20 reproduces, from a source disc S, picture data etc having the superimposed copyright control information for copying limitation and a ticket representing the generation limitation information specifying the number of times of possible copying or reproduction. The reproducing device 20 converts the picture data etc into analog baseband signals and detects the ticket. The reproducing device 20 superimposes the detected ticket on audio signals by watermark processing to output the resulting analog baseband signals.

Abstract: An authentication device which the user wears reads biometrics information and executes individual authentication by verification. Only when the individual authentication has been successfully performed, authentication with an external unit (such as a server) can be started. Then, only when both of the individual authentication based on the biometrics information and the mutual authentication between the external unit (such as a server) and the authentication device have been successfully performed, subsequent data processing such as payment processing can be executed. Therefore, even if a fraudulent third party uses a stolen authentication device, because the party cannot satisfy the start condition of authentication with the external server or a PC, fraudulent transactions and other illegitimate behaviors are effectively prevented.

Abstract: Additional information is transmitted by means of assigning a code to a particular scanning line in a VBI (vertical blanking interval). An initial value of a CRCC (Cyclic Redundancy Check Code) or a formula used to generate a CRCC is switched depending upon the type of additional information inserted in a data frame so that a difference in the initial value causes additional information other than CGMS-A (Copy Generation Management System-Analog) to be regarded as invalid, and thus the additional information does not cause an erroneous operation. However, CGMS-A has to be transmitted in the same manner in any country. To meet this requirement, the same initial value is used when CGMS-A is transmitted. This makes it possible to transmit data in a peculiar format without causing a problem regardless of a country in which transmission is performed. Besides, it is possible to transmit CGMS-A in the same manner regardless of the country.
