1. A process for a positive identification of an individual from a set of identifiable individuals, comprising the steps of: (i) generating a set of classes at least corresponding to the set of identifiable individuals, each class having features which correspond to characteristics of an individual in said set of identifiable individuals; (ii) providing a camera for recording an image sequence as movement information; (iii) recording said image sequence with said camera, said sequence originating from at least one of a typical and predetermined movement action associated with a so far unidentified individual; (iv) evaluating said recorded image sequence through an optical flow thereby producing a feature vector representing movement information contained in the recorded image sequence; (v) comparing said produced feature vector with at least one class of said set of classes; (vi) generating a positive identification signal corresponding to a certain class of said set of classes having features corresponding to said feature vector representing said movement information.
