SIGNATURE VERIFICATION SYSTEM

摘要

SIGNATURE VERIFICATION SYSTEM The present invention provides encoding apparatus for scanning a sample signature and means for producing a code indicative of the pattern produced by the signature. The recording of the code on a suitable record medium may be by any of several available commercial methods dependent on the application e.g. by printing on a cheque by embossing on a credit card, by laser or magnetic recording on a strip of recording material on the record medium. Preferably, a number of sample signatures are scanned and the resultant code is a function of all the signatures so as to take into account legitimate variations in the signature. The present invention further provides verification apparatus for use with a record medium which bears the code which has been produced by said encoding apparatus and then recorded by some means as previously described. Also the verification apparatus is for use with medium bearing the submitted signature. The verification apparatus comprises means for reading the code on the record medium, means for generating a first signal indicative of the signature represented by the code means for reading an actual signature, means responsible to said reading means for generating a further code signal representing the actual signature, means for comparing the first signal with the second signal, and means for indicating the-result of the comparison.
