We work on certain area of biometric signature generation which is anything but fingerprint. We leave retina scan out of this because it is cumbersome and costly. The critic finds faults with us citing 'finger-print' based systems are a kind of full proof as finger print is 'unique'. While they accept that ours is easy to use and has much, much wider applicability, the percentage accuracy were always doubted or looked down upon vis-a-vis finger print based system. Almost all the points made in this article used to be cited by us but such reports by a lead media house help in developing a general agreement.
It is some time to have our developments available commercially but there are a lot of groups world wide pursuing that space and hope to have something in near future. Now excerpts from the Rediff article available with a video demo at http://www.rediff.com/news/report/fool-proof-uid-system-for-indians-blah/20110201.htm :
However, we wish the finger print based system developer very best so that they come up with a more robust system. Competition helps all and the solution may lie in multi modal system i.e. considering more than one mode : finger print is one and what we do, could be the other.
