Abstract
Abstract There are disclosed in the present application, devices and methods for providing identification of a client by his ability to select a correct set of digits from a multiplicity of them on any one of a plurality of grids each with a different order and arrangement of digits on a suitable surface. The client easily establishes his identity by selecting the correct digits from any randomly selected grid at the subscriber location by obtaining in advance, a password from which he determines the correct digits by their positions in all the grids. The accuracy of the client's answer is checked against a register listing, for each client, an independent identification number, and his password. The register also contains a list of correct digits or codes and the grid number for which each code is the appropriate answer. In addition, the present devices and methods may be used for identifying clients for check cashing and for this purpose, the grid may be displayed on the reverse side of a check and the grid identified in the register by check number.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
143 words
A method of establishing the identity of an unknown client at a subscriber location comprising the steps of: first, providing the client with a personal positional code consisting of a sequence of a plurality of letters of the alphabet, each of which locates a digit of a multi-digit number establishing the identity of the client; thereafter, at a subscriber location, presenting the client one of a multiplicity of different grids of digits in which each digit is positionally associated with a letter of the alphabet; obtaining a first response providing a pre-determined form of identification from the client; receiving from the client a second response consisting of a multi digit number from the grid as derived from his previously obtained personal positional code; and verifying the identity of the client by comparing the identification and number obtained from the client against a register.
Claim 2
Independent Claim
143 words
A method of establishing the identity of an unknown client at a subscriber location comprising the steps of: first, providing the client with a personal positional code consisting of a sequence of a plurality of letters of the alphabet, each of which locates a digit of a multi-digit number establishing the identity of the client; thereafter, at a subscriber location, presenting the client one of a multiplicity of different grids of digits in which each digit is positionally associated with a letter of the alphabet; obtaining a first response providing a pre-determined form of identification from the client; receiving from the client a second response consisting of a multi digit number from the grid as derived from his previously obtained personal positional code; and verifying the identity of the client by comparing the identification and number obtained from the client against a register.
Claim 3
Dependent Claim
51 words
A method according to claim 1 further characterized in that each grid selectively presentable to the client at the subscriber location includes substantially all the letters of the alphabet and that there is positioned in a common pattern around and in close proximity to each letter a plurality of different digits.
Claim 4
Dependent Claim
163 words
A set of devices for establishing the identity of an unknown client to a representative at a subscriber location comprising a multiplicity of different grids adapted to be presented to any client in accordance with the choice of the representative and each including at least a majority of letters of the alphabet each defining a position common to all grids of the multiplicity of grids in which the same letter occupies the same position in all grids, and at least one random digit closely associated by proximity to each letter, the ratio of letters to digits being such that at least some of the digits are repeated and associated with different letters in the same grid, and also including means for identifying the grid and a register showing, for each client, an independent identification and a combination of digits which, when given correctly by the client to the representative in response to having viewed any grid at the subscriber location, verify his identity.
Claim 5
Dependent Claim
163 words
A set of devices for establishing the identity of an unknown client to a representative at a subscriber location comprising a multiplicity of different grids adapted to be presented to any client in accordance with the choice of the representative and each including at least a majority of letters of the alphabet each defining a position common to all grids of the multiplicity of grids in which the same letter occupies the same position in all grids, and at least one random digit closely associated by proximity to each letter, the ratio of letters to digits being such that at least some of the digits are repeated and associated with different letters in the same grid, and also including means for identifying the grid and a register showing, for each client, an independent identification and a combination of digits which, when given correctly by the client to the representative in response to having viewed any grid at the subscriber location, verify his identity.
Claim 6
Dependent Claim
49 words
Devices according to claim 3 further characterized in that substantially all the letters of the alphabet appear on each grid and that each letter is surrounded in close proximity by a common pattern of digits each having a predetermined direction relative to the letter with which it is associated.
Claim 7
Dependent Claim
59 words
Devices according to claim 3 further characterized in that substantially all the letters of the alphabet appear on each grid and that each letter is surrounded in close proximity by a set of four digits arranged in a common positional pattern wherein the digits of each set associated with any given letter are different from one grid to another.
Claim 8
Independent Claim
173 words
A method of establishing the identity of an unknown client at a subscriber location comprising the steps of: first, providing the client with a positional code establishing for the client a sequence of a plurality of successive positions each marked by a letter and one of a plurality of orientations surrounding the letter, in each of which a digit of a multi-digit number establishing his identity is located; thereafter, at a subscriber location, presenting the client one of a multiplicity of different grids of letters of the alphabet in which each said letter is in close proximity to and is surrounded by a plurality of numbers, each said number having a specific reference orientation with said letter; obtaining a first response from the client which includes a pre-determined identification code; receiving from the client a second response consisting of a plurality of digits from the grid as derived from the pre-determined identification code; and verifying the identity of the client by comparing the identification and digits obtained from the client against a register.
Claim 9
Independent Claim
173 words
A method of establishing the identity of an unknown client at a subscriber location comprising the steps of: first, providing the client with a positional code establishing for the client a sequence of a plurality of successive positions each marked by a letter and one of a plurality of orientations surrounding the letter, in each of which a digit of a multi-digit number establishing his identity is located; thereafter, at a subscriber location, presenting the client one of a multiplicity of different grids of letters of the alphabet in which each said letter is in close proximity to and is surrounded by a plurality of numbers, each said number having a specific reference orientation with said letter; obtaining a first response from the client which includes a pre-determined identification code; receiving from the client a second response consisting of a plurality of digits from the grid as derived from the pre-determined identification code; and verifying the identity of the client by comparing the identification and digits obtained from the client against a register.
Claim 10
Dependent Claim
94 words
Devices for establishing the identity of an unknown client at a subscriber location comprising a multiplicity of different grids each including substantially all the letters of the alphabet, each letter being surrounded in close proximity by a set of four digits arranged in a common positional pattern wherein the digits of each set associated with any given letter are different from one grid to another, and a register showing, for each client, an independent identification and a combination of digits which, when given correctly by the client at the subscriber location, verify his identity.
