ABSTRACT:
A personal identification system and a method for verifying a person presenting a record member such as a credit card or other member so as to eliminate fraud from the procedure. The record member or card contains invisible magnetic recordings of a full frame video picture signal and code defining signal recordings which, when reproduced by transducer sensing, may be employed to operate a motor or solenoid for access to a room or building. The video picture signal may contain image information derived from scanning the face of the person presenting the record member, his signature or other physical characteristic, which may be used to modulate an image generating device such as a cathode ray tube and present such image for verification. The reproduced code signal may also be employed for verification by matching same with another code generated by keyboard or from a memory. In another form, the recordings on the record member may be derived from a microphone into which the person to be identified speaks. Such recordings may be obtained from analog speech signals which are digitized and scrambled for security purposes.
