Metadata processing for an optical medium

A storage device comprising:

• a processor;
• a memory coupled to the processor;
• and
• at least one optical medium coupled to the processor;
• the processor configured to
• encrypt and write data to the at least one optical medium based upon a plurality of encryption keys stored on a key management server, the data having metadata associated therewith,
• store the metadata in the memory,
• read selected encrypted data from the at least one optical medium,
• retrieve the metadata associated with the selected encrypted data,
• retrieve a respective encryption key based upon the retrieved metadata,
• decrypt the selected encrypted data based upon the respective encryption key, and
• delete selected metadata from the memory in response to a delete instruction so that the respective data is unreadable.

A computer-implemented method comprising:

• using a processor to
• encrypt and write data to at least one optical medium coupled to the processor based upon a plurality of encryption keys stored on a key management server, the data having metadata associated therewith,
• store the metadata in a memory coupled to the processor,
• read selected encrypted data from the at least one optical medium,
• retrieve the metadata associated with the selected encrypted data,
• retrieve a respective encryption key based upon the retrieved metadata,
• decrypt the selected encrypted data based upon the respective encryption key, and
• delete selected metadata from the memory in response to a delete instruction so that the respective data is unreadable.

A computer-readable medium comprising computer executable instructions that when executed by a processor cause the processor to perform operations comprising:

• encrypting and writing data to the at least one optical medium based upon a plurality of encryption keys stored on a key management server, the data having metadata associated therewith,
• storing the metadata in the memory,
• reading selected encrypted data from the at least one optical medium,
• retrieving the metadata associated with the selected encrypted data,
• retrieving a respective encryption key based upon the retrieved metadata,
• decrypting the selected encrypted data based upon the respective encryption key, and
• deleting selected metadata from the memory in response to a delete instruction so that the respective data is unreadable.
