share
A Bio-metrics system is actually a pattern recognition system that utilizes various patterns like iris, retina and biological traits like fingerprint, voice recognition, facial geometry and hand geometry. What makes Bio-metrics really attractive is that the various security codes like passwords and ID cards can be interchanged, stolen or duplicated. To enhance the security and reliability of the system, physiological traits can be used. This paper gives the overview of key bio-metric technologies and basic techniques involved and their drawbacks. Then the paper illustrates the working of ECG and the various opportunities for ECG are also mentioned.
