Abstract
Abstract A verification system for determining whether a person is authorized to use a connected system is disclosed as comprising reading means for reading first data from a card proffered by the person who intends to use the connected system, input means manually operable by the person to enter second data into the verification system, the second data being different from the first data, function storage means for storing a plurality of different functions, each having at least one variable, and, in response to an address code formed from a portion of at least one of the read first data and the entered second data, for looking up and generating a specific stored function, calculating means for substituting a remaining portion of at least one of the first and second data into the variable of the generated specific function and for calculating a value from said function, and checking means for checking whether a predetermined relationship exists between a further remaining portion of at least one of the first and second data, and the calculated value, the existence of said predetermined relationship being operative to allow the person to use the connected system.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
188 words
A verification system for determining authorized use of a connected system, said verification system comprising: reading means for reading first data from a card; manually operable input means for entering second data into said verification system, said second data being different from said first data; function storage means for storing a plurality of different functions, each having at least one variable, said function storage means being responsive to an address code formed from a portion of at least one of the read first data and the entered second data for looking up and generating a specific function; calculating means for substituting a remaining portion of at least one of the first and second data not used in said address code into the variable of said generated specific function for calculating a function result; and checking means for checking whether a predetermined relationship exists between a further remaining portion of at least one of the first and second data not used in said address code and said calculated function result, and providing an access signal upon the existence of said predetermined relationship to allow use of said connected system.
Claim 2
Dependent Claim
188 words
A verification system for determining authorized use of a connected system, said verification system comprising: reading means for reading first data from a card; manually operable input means for entering second data into said verification system, said second data being different from said first data; function storage means for storing a plurality of different functions, each having at least one variable, said function storage means being responsive to an address code formed from a portion of at least one of the read first data and the entered second data for looking up and generating a specific function; calculating means for substituting a remaining portion of at least one of the first and second data not used in said address code into the variable of said generated specific function for calculating a function result; and checking means for checking whether a predetermined relationship exists between a further remaining portion of at least one of the first and second data not used in said address code and said calculated function result, and providing an access signal upon the existence of said predetermined relationship to allow use of said connected system.
Claim 3
Dependent Claim
86 words
The verification system according to claim 1, wherein said function storage means generates said specific function in response to an address code formed from a portion of the entered second data; said calculating means substitutes a remaining portion of the second data not used in said address code into at least one variable of said generated specific function; and said checking means checks whether a predetermined relationship exists between at least a portion of the first data and said calculated function result from said calculating means.
Claim 4
Dependent Claim
99 words
The verification system according to claim 1, wherein said function storage means generates said specific function in response to an address code formed from a portion of each of the first and second data; said calculating means substitutes a remaining portion of the first and second data not used in said address code into at least one variable of said generated specific function; and said checking means checks whether a predetermined relationship exists between a further remaining portion of the first and second data not used in said address code and said calculated function result from said calculating means.
Claim 5
Dependent Claim
16 words
The verification system according to claim 1, wherein said connected system is a bank transaction system.
Claim 6
Dependent Claim
35 words
The verification system according to claim 4, wherein said bank transaction system comprises at least one cash dispensing apparatus which is operable in response to the existence of said predetermined relationship in said checking means.
Claim 7
Dependent Claim
180 words
A verification system for determining authorized use of a connected system, said verification system comprising: a card reader for reading first data from a card; a manually operable keyboard for entering second data into said verification system, the second data being different from the first data; a storage device for storing a plurality of different functions each having at least one variable, and in response to an address code formed by a portion of at least one of the read first and entered second data for generating a specific function; and a microprocessor for substituting a remaining portion of at least one of the first and second data not used in said address code into the variable of said generated specific function, for calculating a function result, for checking whether a predetermined relationship exists between a further remaining portion of at least one of the first and second data not used in said address code and said calculated function result, and for providing an access signal upon the existence of said predetermined relationship to allow use of said connected system.
Claim 8
Dependent Claim
180 words
A verification system for determining authorized use of a connected system, said verification system comprising: a card reader for reading first data from a card; a manually operable keyboard for entering second data into said verification system, the second data being different from the first data; a storage device for storing a plurality of different functions each having at least one variable, and in response to an address code formed by a portion of at least one of the read first and entered second data for generating a specific function; and a microprocessor for substituting a remaining portion of at least one of the first and second data not used in said address code into the variable of said generated specific function, for calculating a function result, for checking whether a predetermined relationship exists between a further remaining portion of at least one of the first and second data not used in said address code and said calculated function result, and for providing an access signal upon the existence of said predetermined relationship to allow use of said connected system.
Claim 9
Dependent Claim
