Abstract
A media storage device may store content adapted to be inserted in a media reader for reading the content. The content may be encrypted, and the media storage may include a smart object physically attached to the media storage and arranged to be read by a smart object reader of the media reader. The smart object may include security information for decrypting the content in the smart object reader.
Claims24
A media storage device to be inserted in a media reader having an associated smart object reader, the media storage device comprising:
- a storage medium comprising a plurality of encrypted sections and unencrypted sections and configured to store encrypted content in the encrypted sections and unencrypted content in the unencrypted sections, at least one of the encrypted sections having encrypted content based upon an encryption format different from other encrypted sections;
- and
- a smart object attached to said storage medium and configured to be read by the smart object reader, said smart object comprising
- security information for decrypting the encrypted content in the encrypted sections, and
- respective locations for reading the unencrypted content in the unencrypted sections.
An electronic device for reading a media storage device comprising a storage medium comprising a plurality of encrypted sections and unencrypted sections storing encrypted content in the encrypted sections and unencrypted content in the unencrypted sections, at least one of the encrypted sections having encrypted content based upon an encryption format different from other encrypted sections, and a smart object attached to the storage medium, the electronic device comprising:
- a media reader configured to receive the media storage device;
- and
- a smart object reader cooperating with said media reader and configured to read the encrypted content of the smart object, the smart object comprising
- security information for decrypting the encrypted content in the encrypted sections, and
- respective locations for reading the unencrypted content in the unencrypted sections.
A method for decrypting encrypted content stored in a storage medium of a media storage device to be inserted in a media reader, the media reader having an associated smart object reader, the method comprising:
- sending a query from the smart object reader to a smart object attached to the storage medium, the storage medium comprising a plurality of encrypted sections and unencrypted sections to store the encrypted content in the encrypted sections and unencrypted content in the unencrypted sections, at least one of the encrypted sections having encrypted content based upon an encryption format different from other encrypted sections;
- and
- reading the smart object with the smart object reader to retrieve
- security information stored in the smart object for decrypting the encrypted content in the encrypted sections, and
- respective locations for reading the unencrypted content in the unencrypted sections.
