Abstract
After a digital content is loaded into an information terminal such as a PC, ID information unique to a viewer or a user of the PC is imprinted into the content. The ID information is imprinted into a predetermined location of the content or alternatively, it may be imprinted over the entire content in the form of a spatial frequency. The content with an ID added thereto is then enabled to be used in the terminal.
Claims39
A method for imprinting identification information (ID) in a digital content comprising data values, the method comprising:
- loading the digital content into an information terminal at which the digital content will be used;
- and
- imprinting a representation of an ID associated with the information terminal or the user thereof into a perceivable portion of the loaded content.
A method for distributing a digital content comprising:
- issuing a request for a digital content from an information terminal to a content manager, the request identifying the information terminal or a user thereof;
- receiving a requested content transmitted by the content manager in response to the request, the received content being encrypted;
- receiving a decryption program transmitted by the content manager in response to the request, the decryption program embedding ID information identifying the information terminal or the user thereof;
- and
- processing the content using the received decryption program to produce a decrypted content having the ID information imprinted therein.
A method for distributing a digital content comprising:
- receiving a request for a digital content at a content manager from an information terminal, the request identifying the information terminal or a user thereof;
- transmitting a requested content to the information terminal in response to the request, the transmitted content being encrypted;
- and
- transmitting a decryption program to the information terminal in response to the request, the decryption program embedding ID information identifying the requesting information terminal or the user thereof, the decryption program being operable on the transmitted encrypted content for producing a decrypted content having the ID information imprinted therein.
An apparatus for imprinting identification information (ID) in a digital content comprising:
- a communication section for receiving an encrypted digital content and a decryption program embedding ID information, the decryption program operable to decrypt the encrypted content and to imprint the embedded ID information into the decrypted content;
- and
- means for utilizing the received decryption program to produce from the received encrypted content a decrypted content having the ID information imprinted therein.
An apparatus for imprinting identification information (ID) in a digital content comprising:
- a communication section for receiving a digital content;
- and
- an ID imprinter for imprinting the ID into a perceivable portion of the received content.
