Abstract

As the abundance of computers and technology grows, a powerful security system is required; biometrics. Already, there are fingerprint, retinal, voice, hand geometry, and face geometry biometric systems, but these do not possess the necessary security levels that government and financial institutions require. Although an unexplored area of biometrics, using DNA as a biometric security tool is an effective and almost perfect solution. The purpose of this research was to create a biometric system in which DNA information was analyzed and matched with the STR count of a specific individual in a database and recorded whether or not the individual was accepted. In biometrics, two figures are of major concern. The FRR, false rejection rate, and the FAR, false acceptance rate. The FRR is the percentage of users that are falsely rejected from the system and the FAR is the percentage of individuals that are falsely accepted by the system. It was hypothesized that if forensic DNA typing is used as a biometric tool, then the the FRR and FAR of the biometric system would be 0.0%. The method of conducting the experiment was to separate 500 individuals from a database into two even groups. The first group had its DNA information entered into the database and the other group had been left out of the database. The system ran all 500 individuals and the rejected and accepted individuals were recorded. Then, all 500 individuals were entered into the database and the rejected and accepted individuals were recorded. The results indicated that all individuals that were to be rejected, were rejected, and those that were to be accepted, were accepted. Using a chi-square test, it was concluded that the system worked flawlessly. Therefore, my study indicates that using DNA as a biometric tool, without identical twins, is a flawless solution.
