Zugangsberechtigungs- oder Identifikationsmedium und Verfahren zu seiner Herstellung

摘要

The invention relates to an access authorization or identification medium for authorization control and a method for the production of said medium. The invention also relates to a method for identifying or checking access authorization of an individual with the aid of said medium. The front side of the inventive medium has a picture of the face of the individual to be recognized by the medium or to whom the medium should grant access to a protected area. Coded computer-generated holographic information of the picture is also stored on the medium. This configuration makes it possible to verify at any given time the consistency of the data found on the medium. The coded holographic information stored on the medium can be read with an appropriate reading device and the picture can be reconstructed on the basis of the information read. Any manipulation of the medium can be detected by comparing the reconstructed picture with the picture on the front side of the medium.
