Method and apparatus for secure data entry using multiple function keys
First Claim
1. A method for data entry using a multipurpose input device having a sensor comprising:
- sensing a biometric characteristic of an object;
generating an expression by associating the biometric characteristic with enrollment data, the expression identifying at least a portion of a specific finger unique to a individual user of the multipurpose input device;
determining positional information corresponding to a source location of the biometric characteristic; and
generating a token representing a desired data entry based on the expression and the positional information.

Abstract
A method and apparatus for secure data entry by sensing biometric information and determining a desired data based on the biometric information. The method can include sensing a biometric characteristic of an object, generating an expression by associating the biometric characteristic with enrollment data, the expression identifying at least a portion of a specific finger unique to a individual user of the multipurpose input device, determining positional information corresponding to a source location of the biometric characteristic, and generating a token representing a desired data entry based on the expression and the positional information. The positional information or the expression can indicate a subset of a set of potential data entry values and the combination of the positional information and the expression can uniquely define the token representing a desired data entry of the subset of potential data entry values.

15. A data entry device, comprising:
-
a keypad;
a biometric sensor coupled to the keypad; and
a controller coupled to the biometric sensor, the controller configured to sense a biometric characteristic of an object at the biometric sensor, generate an expression by associating the biometric characteristic with enrollment data, the expression identifying at least a portion of a specific finger unique to a individual user of the data entry device, determine positional information corresponding to a source location of the biometric characteristic, and generate a token representing a desired data entry based on the expression and the positional information. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A communication device comprising:
-
a keypad including at least one key, the at least one key having at least two functions associated with the at least one key;
a fingerprint reader coupled to the at least one key, the fingerprint reader being configured to capture a fingerprint image;
a database including data related to a first fingerprint image; and
data related to a first function of the at least two functions;
a controller coupled to the fingerprint reader, the controller including a fingerprint analysis module configured to analyze the fingerprint image; and
a fingerprint function determination module configured to determine a function corresponding to a combination of data relating to the at least one key and data related to the first fingerprint image.
