Abstract: In a novel fashion, the invention employs bar codes and networks to facilitate and standardize the authentication of software licenses, or licenses of other digital content, such as audio and video recordings. The software or other digital content may be purchased along with the license, or the license may be obtained separately from the software or digital content. The former pertains in particular to so-called shrinkwrapped software that is distributed on storage media. Media types include, but are not limited, to compact disks (CDs), digital versatile disks (DVDs), magnetic diskettes, and magnetic tape.
