IBM Corp. will release a new digital rights management technology Monday, helping music publishers to prevent unauthorized music copying, said a company spokesman.

IBM currently uses Cryptolope Live as its rights management technology in its DB2 Digital Library database product. Billed as an encrypted envelope for data, Cryptolope requires a digital key to unlock it. Users can preview the data, then decide whether to pay for the key or not. Multiple keys can be used for increased security, and the encryption can travel on networks without third parties being aware of its presence, the company said.

IBM’s new technology builds in additional restrictions, preventing copies of songs downloaded from pirate music sites or transferred by e-mail or other sources from being played fully, or more than once, or at all.
