Content output apparatus, content output method and content aquisition apparatus
First Claim
1. A content output apparatus for outputting a content to a storage device via a network and recording it therein, comprising:
- an encryption processing unit configured to apply an encryption processing to the content;
a recording unit configured to record the content to which the encryption processing has been applied by the encryption processing unit and identification information which identifies the content itself on the network in the storage device so as to be related with each other; and
an output unit configured to read a requested content from the storage device on the basis of a content acquisition request supplied via the network, decrypt the encryption, further apply a predetermined processing to the content, and transmit it on the network.

6. A content output method for outputting a content to a storage device via a network and recording it therein, comprising:
-
a first step of applying an encryption processing to the content;
a second step of recording in the storage device the content to which the encryption processing has been applied in the first step and identification information which identifies the content itself on the network so as to be related with each other; and
a third step of reading a requested content from the storage device on the basis of a content acquisition request supplied via the network, decrypting that encryption, further applying a predetermined processing to the content, and transmitting it on the network. - View Dependent Claims (7, 8)

9. A content acquisition apparatus for acquiring a predetermined content via a network from a storage device having recorded therein an encrypted content and identification information of a device configured to decrypt a code of the content so as to be related with each other, comprising:
-
a selecting unit configured to select a predetermined content from the content recorded in the storage device;
a requesting unit configured to request decryption of the code of the content selected by the selecting unit and acquisition the content from the device which is indicated by identification information corresponding to the content; and
an acquisition unit configured to acquire the content transmitted from the device on the network on the basis of the request of the requesting unit. - View Dependent Claims (10)
