Computational Forensics

Pattern processing is a central aspect of data evaluation in many scientific disciplines, including computational security and forensics. Some of the related tasks in these fields are more or less completely based on pattern evaluation. Just take biometrics as an example, and the evaluation of patterns captured from human fingerprints, iris, face, handwriting probes, hand veins etc. But also the familiarity aspect of a pattern can play an important role. In document security, we find the majority of official document backgrounds equipped with a common Guilloche pattern. Moreover, patterns can be employed to detect digital watermarks, to recognize spam e-mail, or to break cryptographic schemes. In a similar sense we find computational forensic in a large scale based on the evaluation of patterns. Nearly all forensic evidence more or less directly refers to patterns: impression patterns like fingerprints or shoe prints, trace evidence, biological or toxicological evidence, as well as digital forensics.
