Personal verification system
First Claim
1. The method of operating a personal verification system including encoding means and code word input means coupled to the encoding means for verifying the authority of an individual to complete transactions on the basis of the combination of an individual code word which is peculiar to the individual, a secret code word which need only be known to the individual and a compiled code word which is derived from the other of the code words, the method comprising the steps, performed in selected sequence, of:
- preparing a logical encoding status in accordance with a selected logical combination of both the individual code word and a secret code word received from the individual prior to verification of his authority to complete a transaction;
encoding the combination of both the individual code word and the secret code word received from the individual in accordance with said logical encoding status to produce a compiled code word therefrom;
preparing a record of said compiled code word for subsequent use in verifying the authority of the individual to complete a transaction;
applying to the code word input means of the system both an individual code word for identifying the individual attempting to complete a transaction and a secret code word from such individual;
preparing a logical encoding status in the encoding means of the system in accordance with said logical combination of both the individual code word and secret code word applied to the code word input means of the system;
encoding the combination of both the individual code word and the secret code word applied to the code word input means in accordance with said logical encoding status prepared in the encoding means of the system to produce a corresponding compiled code word therefrom;
comparing said corresponding compiled code word with the compiled code word from said record for the authorized individual having such individual code word; and
controlling completion of the transaction in response to the comparison of the compiled code word from said record with said corresponding compiled code word produced from the applied individual code word and secret code word received from the individual attempting to complete the transaction.

Abstract
A customer code word issuing machine is provided wherein a customer manually inputs to the machine his secret password. The machine encodes the password and displays his corresponding issued code word. A verification machine is provided which includes a dial or keyboard for manually inputting the customer'"'"'s password and the issued code word. The verification machine encodes the inputted password to derive an output for comparison with the manually inputted code word to derive an output indicative of the truth or falseness of the match of the code word with the respective password. The verification machine may be employed to open a lock, to allow use of a credit card for a telephone call, purchase of goods, etc.

6. Apparatus for verifying the authority of an individual to complete a transaction on the basis of logical manipulation of an individual'"'"'s identifying code word, his secret code word and an encoded word logically derived from at least one of such code words, the apparatus comprising:
-
encoding means providing a variable encoding operation which is a function of the logical combination of a pair of code words applied thereto for producing an encoded word therefrom in accordance with said encoding operation which is also determined by said pair of code words; input means coupled to said encoding means for applying thereto an individual'"'"'s identifying code word and the individual'"'"'s secret code word as said pair of code words during the course of a transaction for providing said encoding operation therefrom in accordance with said logical combination of the applied individual'"'"'s identifying code word and secret code word, said encoding means producing said encoded word in accordance with said encoding operation from the applied individual'"'"'s identifying code word and secret code word; means providing an encoded word prepared by encoding the combination of the authorized individual'"'"'s identifying code word and secret code word in accordance with a variable encoding operation which is determined by said logical combination of the authorized individual'"'"'s identifying code word and secret code word; and means for comparing said encoded word prepared for the authorized individual with the encoded word produced during the course of a transaction to complete the transaction with respect to said individual'"'"'s identifying code word in response to comparison of said encoded words. - View Dependent Claims (7)
