Abstract
A personal identity verification process and system adopts an error correcting output code (ECOC) classifier approach. Image data representing an input facial images is processed to generate a first (ECOC) classifier output vector and image data representing a class of different training images of the face of an individual are processed to generate a set of second ECOC classifier output vectors. Authenticity of the input facial image against the class of training images is evaluated by measuring distance between the first ECOC classifier output vector and the set of second ECOC classifier output vectors using a first order Minkowski metric.

A personal identity verification process for evaluating authenticity of an input facial image against a class of different training images representing the face of an individual, the process including
- processing image data representing the input facial image to generate a first error correcting output code (ECOC) classifier output vector,
- processing image data representing the different training images of the class to generate a set of second ECOC classifier output vectors,
- comparing the first ECOC classifier output vector with the set of second ECOC classifier output vectors, and
- evaluating authenticity of the input facial image with respect to the class of training images in dependence on the comparing.
