Can someone layout how biometric info can be abused?<p>In Israel, biometroic ID cards are standard, though you can request a non biometric I.D. and not be fingerprinted/eyeprinted/face-scanned [Which of course probably gets you straight on a black-list and shadowed by the Mossad, but whatever..]<p>I have heard there is talk now about making the database of everyone's biometric markers publicly available.<p>What are the risks in that, and why should someone choose to opt out? I mean, it certainly sounds like a terrible idea, but I am having a hard time articulating out the threat.<p>By way of prior - For many years the public had access to a database of every citizen's address, phone, parents' first and maiden names, and age with D.O.B.<p>The claim was that this data is available on the black market, and better to be up front about it and not use this info for identifying yourself.<p>AFAIK that experiment was considered a success, though the DB is no longer available.
