Design of DNA Based Biometric Security System for Examination Conduct

Abstract

Biometrics is a technique of using characteristics and behavioral traits for identification of people this is more effective that common personal identification number(PIN) for an improved security technique. The basic procedure in a biometric system is the collection of biometric data through a sensor elements, the module extracted bares biometric data which is compared to its templates in a database to identify the data subject. In this work, the design of DNA (Deoxyribonucleic acid) based biometric was carried out  for securing a system for Examination Conduct. DNA samples are to be collected from would be candidates through Electrophoresis platforms, it covers slab-gels to capillary electrophoresis (CE), and this is done by the use of a cross-linked polymer solution to separate the DNA molecules, After this procedure data collection by the Capillary Electrophoresis is done by where the alleles are analyzed using software that accompanies the Capillary Electrophoresis machine. With the time duration of about four hours the collection of data, with DNA extraction in the initial, then acquisition of data from 16 STRs with the sex determination locus. The DNA profiling shows the value of VNTR (variable number tandem repeat) which repeats at a number of distinctive loci the templates are encrypted using algorithmic transformation of biometric samples. Then the STR (Short Tandem Repeats) value is found by which is generated number with several tens of digits, and this results in a personal identification information that is unique which will be used for statistical and theoretical analysis for final recognition and authentication of the personality concerned.
