ABSTRACT

This chapter focuses on studying synthetic sequences of amino acids like DNA (deoxyribonucleic acids) and proteins as one of the future targets of inverse biometric research. Existing biometric technologies which deal with objects like fingerprints, iris scans, face scans, voice patterns, signatures and combined biometrics can be effected by various disturbances (both environmental and physical) which reduce accuracy in personal identification systems. The environmental disturbances include bright light for faces and irises, dry skin for fingerprint, or background noise for voice recognition. The physical disturbances include voice changes due to illness or other factors, and signature and handwriting changes due to aging and mood. DNA is not affected by environmental and physical disturbances. Historically, DNA signatures used in forensics have proven that people can be identified with high accuracy. The main problem with DNA is the enormous time and resources required for sequencing and processing (alignment, matching, storing, etc.). However, future technology will ensure real time DNA sequencing and processing. Another problem is a privacy concern which promotes work on synthetic DNA instead of actual sequences taken from humans.
