Abstract
A device having a biometric input device is configured to allow a user to enter a character sequence for use in validation using the biometric input device. A predetermined assignment of characters to enrolled biometric templates allows a user to determine a sequence of biometric inputs to provide to enter an appropriate character sequence.
Claims27
A method of handling receipt of a character sequence, said method comprising:
- generating an image that illustrates a random association between a plurality of fingers and a plurality of characters;
- receiving, via a biometric input device, a candidate sequence of a plurality of biometric candidates;
- forming a character sequence from said candidate sequence by, for each biometric candidate in said candidate sequence:
- determining that said each biometric candidate matches a stored biometric template;
- determining, according to the association, that said stored biometric template is associated with a character from among the plurality of characters;
- and
- transmitting said character sequence to an identity verification element.
An apparatus comprising:
- a memory storing a plurality of biometric templates;
- a biometric input device;
- a storage component interface for receiving an identity verification element for communication therewith;
- a processor adapted to:
- generate an image that illustrates a random association between a plurality of fingers and a plurality of characters;
- receive, from said biometric input device, a candidate sequence of a plurality of biometric candidates;
- and
- form a character sequence from said candidate sequence by, for each biometric candidate in said candidate sequence:
- determining that said each biometric candidate matches a biometric template among said plurality of biometric templates;
- determining, according to the association, that said biometric template is associated with a character from among the plurality of characters;
- and
- transmit said character sequence to an identity verification element.
A non-transitory computer readable medium containing computer-executable instructions that, when performed by a processor, cause said processor to:
- generate an image that illustrates a random association between a plurality of fingers and a plurality of characters;
- receive a candidate sequence of a plurality of biometric candidates;
- and
- form a character sequence from said candidate sequence by, for each biometric candidate in said candidate sequence:
- determining that said each biometric candidate matches a stored biometric template;
- and
- determining, according to the association, that said stored biometric template is associated with a character from among the plurality of characters;
- and
- transmit said character sequence to an identity verification element.
