Biometric System Vulnerability as a Compromising Factor for Integrity of Chain of Custody and Admissibility of Digital Evidence in Court of Justice: Analysis and Improvement Proposal

Summary/Abstract: Biometric systems play an important role in digital investigation process as a important factor of authentication and verification applications, since they are strongly linked to the holder of a biometric traits and possible suspect. Thus it is important that biometric systems can be designed to withstand attacks when employed in security-critical applications, especially in unattended remote applications such as energy plants, access to borders at airports, ecommerce etc. Biometric recognition either raises important legal issues of remediation, authority, and reliability, and, of course, privacy. The standard assumptions of the technologists who design new techniques, capabilities, and systems are very different from those embedded in the legal system. Legal precedent on the use of biometric technology is growing, with some key cases going back decades and other more recent cases having raised serious questions about the admissibility of biometric evidence in court. In this paper authors is about to explain influence of reliability of biometric system on general acceptance of digital evidence in Court of Justice process. Through paper authors are also about to propose vulnerability assessment of biometric system as improvement factor of reliability of existing methodology for preserving chain of custody of digital evidence called DEMF (Digital Evidence Management Framework). Improvement proposal is presented as an introduction of phase of biometric vulnerability evaluation methodology within proposed framework called APDEMF (Admissibility procedure of DEMF). Using UML (Universal Modeling Language) modeling methodology authors are about to represent a APDEMF framework which will describe essential phases of the same process.
