Off-the-shelf components and custom algorithms perform forensic analysis of print used in crime.

Forensic analysis of print is crucial for combating fraud and counterfeiting crimes. Counterfeiters and document fraudsters often escape prosecution because of the difficulty in establishing a connection between them and their printing equipment that is sufficient to satisfy the courts. The problem is exacerbated by the wide range of inexpensive and high-quality laser and inkjet printing machines available on the market. To meet these challenges, the London College of Communication (LCC) forensic research program is working to improve the methodology of 'fingerprinting' printing machines using high-resolution digital image analysis.
