As a result of global concern by law enforcement agencies, Canon Incorporated has developed anti-counterfeiting technologies in their newer model color photocopiers (Models CLC350 and CLC550) and ink-jet systems (Model CJIO). The case discussed in this paper involved the anti-counterfeiting technology implemented by Canon; it also included unusual forensic evidence not observed before. In the case profiled in this paper, a Canon CLC550 color photocopier was suspected as the instrument used in the counterfeiting of bundles of Bank of Canada $5.00 and $20.00 notes seized at a residence. Because of the security features of the copier, the examination of the copier revealed recent evidence of permanent images being formed on the transfer drum; this yielded tangible evidence to confirm that the photocopier had produced a banknote. The investigation confirmed that the decoding system is viable and can provide a direct link between the photocopier and the counterfeit copies. It is only a matter of time before all photocopier manufacturers implement security technology similar to that of Canon's. 5 figures
