Personal authority verification system
First Claim
1. In a verification system for verifying the authority of an individual executing a document as well as the authenticity of said document, each authorized individual being identified by a unique code name, each document having designated marking areas for receiving a code signature, said code signature corresponding to said code name formed in accordance with a randomly generated alphabet display, said code name and alphabet display being termed indicators of authority, said system including means for enciphering one of said indicators of authority and an indicator of authenticity, and means for forming on said document said encipherment and said indicator of authenticity in deciphered form, a verifier comprising:
- means for reading said encipherment and indicator of authenticity from said document,means for deciphering said encipherment to recover said indicator of authenticity and said one of said indicators of authority,means for producing the other indicator of authority,means for comparing said recovered indicator of authenticity with said indicator of authenticity read from said document, andmeans for comparing said recovered indicator of authority with said code signature and said other indicator of authority to determine if the code signature corresponds to said code name formed as a code signature using the generated alphabet display.

Abstract
An authority verification system for verifying the authority of the user of a credit or other account by assigning a different code name to each account. When an account is used, the code name, in enciphered form is written on a certificate along with other information necessary to debit the credit account. Verification apparatus deciphers the code name and compares it with the code name assigned to the account being debited.
In addition, when the credit or other account is either a checking account or charge account, other enciphered codes may be included on each check and credit card to protect against alteration of the check or credit card and thus assure check or credit card authenticity.

4. A verification system which verifies the authority of a user of a charge account as well as the authenticity of a charge card, each authorized user being identified by a code name comprising;
-
a charge card having formed thereon an encipherment of a code name, uniquely associated with a charge account, and the account number, a credit slip exhibiting a randomly generated alphabet display and marking areas for receiving a code signature, said code signature being formed from said code name in accordance with said alphabet display, and verification means including means for deciphering said encipherment of said code name and account number and means, responsive to said alphabet display, said code signature and said code name for determining if the code name represented by the code signature corresponds to the code name assigned to said account number.

5. A verification system for verifying the authority of a person executing a document as well as the authenticity of said document, each authorized person being identified by a unique code name, each document having designated marking areas for receiving a code signature, said code signature corresponding to said code name formed in accordance with a randomly generated alphabet display, said code name and alphabet display being termed indicators of authority, said document further comprising an indicator of authenticity and an indicator of authority in enciphered form and an indicator of authenticity in unenciphered form, said system comprising:
-
means for reading said indicators in enciphered and unenciphered form and said code signature from said document, means for deciphering said enciphered indicators, means responsive to said alphabet display, code signature and code name for verifying that the code signature deciphered in accordance with the alphabet display corresponds to the code name, and means for comparing said deciphered indicator of authenticity with said unenciphered indicator to determine correspondence. - View Dependent Claims (6, 7, 8, 9)

10. In a verification system for verifying the authority of a person executing a document, said document including a code signature corresponding to a code name formed in accordance with a randomly generated alphabet display, said code name and said alphabet display being termed indicators of authority, and an encipherment of one of said indicators of authority, a decipherment device comprising;
-
means for deciphering said encipherment from said document, and means responsive to said code signature and said deciphered encipherment for comparing said code name with said code signature to determine correspondence between the code name and the code signature to determine correspondence between the code name and the code name represented by the code signature. - View Dependent Claims (11)

12. A method for automatically verifying the authority of a person executing a document comprising the steps of:
-
a. assigning to persons having authority a unique code name, b. providing a randomly generated alphabet display comprising a randomly generated mark or space for each letter of the alphabet, c. recording on said document a code signature comprising a series of marks and spaces corresponding to said code name as determined by said alphabet display, said code name and alphabet display forming indicators of authority, d. reading said code signature from said document, and e. electronically comparing the code name with the code signature and the alphabet display to determine correspondence between the code name and the code name represented by the code signature. - View Dependent Claims (13, 14, 15, 16)

20. A personal verification system for verifying the authority of an individual executing a document as well as the authenticity of said document wherein each authorized individual is identified by a unique code name each said document comprising a randomly generated alphabet display consisting of random marks and spaces corresponding on a one-to-one basis with the letters of the alphabet, designated marking areas for receiving a code signature which is formed by either marking in or leaving blank areas corresponding to each letter of the code name in accordance with the marks and spaces of said randomly generated alphabet display thereby causing the code signature to vary randomly from document to document, and an account identification display identifying the account of a specific authorized individual, said verification system comprising document reading means for sensing on an executed document each of said randomly generated alphabet display, said code signature and said account identification display and providing respective outputs indicative thereof, code name generating means responsive to the account identification output of said document reading means for generating an output corresponding to the code name of the authorized individual to whom the account is assigned, means connected to said document reader means and said code name generating means for producing an output corresponding to the correct encoding of the code name assigned to the identified account based on the randomly generated alphabet display on the specific document being read by said document reading means, and means for comparing the code signature sensed by said document reading means with the correct encoding of the code name produced by said last mentioned means and providing an output indicating the authority of the individual that executed the document and the authenticity of the document.
