Abstract
A scrambled facial image of an ID card bearer is recorded upon a card and is descrambled only by using the proper descrambling control code assigned to the proper bearer upon verification of the authenticity of the bearer. The pixel scrambling method prevents card duplication, as a reproduced card will unscramble only the image of the proper bearer, and the method inherently prevents producing a card which can be unscrambled by a verifier. Updated scrambling codes are used for newly issued cards from enhanced security. Issue clerk initials are automatically recorded upon the card to deter unlawful card issuance. Also, unscrambled image portions are video recorded for investigation of unlawful use.
