  abstract =	 {The work studies the problem of copyright protection
                  of software using cryptographic fingerprinting. The
                  identity of software must be unique for each
                  copy. There are two classes of identities: one is
                  based on equivalent variants of the program and the
                  other applies behaviour of the software as its
                  identity. For these two types of identity, we
                  introduce two different fingerprint schemes. The two
                  schemes use digital signatures and can be easily
                  combined and extended to be resilient against
                  partial fingerprint destruction.},
  annote =	 {Broadly discusses issues of protecting software
                  intellectual property, distinguishing between
                  fingerprints which the author considers to be
                  universally verifiable and software watermarks,
                  which he considers to be recoverable only by the
                  owner. Introduces two methods of fingerprinting, one
                  by encoding the watermark in the choice of
                  equivalent instructions and a second by adding
                  redundant states in the behaviour of the program
                  during a particular execution.},
