Abstract
A method and apparatus are provided for verifying the identity of a person by establishing and storing a standard vector for said person based upon predetermined characteristics derived from a number of handwriting samples, and then comparing said standard with a vector derived from a corresponding sample of handwriting provided by said person at the time the identity of said person is to be verified. Derivation of the vector is accomplished by digitizing an analog waveform representing forces generated by writing, compressing the digitized information, extracting Haar coefficients and directly observable features from the compressed digital information, and deriving a vector from said Haar coefficients and said directly observable features.
