Abstract A highly secure personal identification badge is achieved by having an area which contains machine readable information and also having a printed region having embedded data in the image printed thereon. A method of producing the identification badge, includes the steps of: forming a digital image of the badge holder; generating an array of random numbers using a random number generator that employs a seed value; adding the array of random numbers to the digital image to produce a modified digital image; and printing the modified digital image on the identification badge. The badge is authenticated by scanning the image on the identification badge to produce a recovered digital image; and correlating the array of random numbers with the recovered digital image to produce a validity check of the identification badge.
A method of producing an authenticatable identification badge, comprising the steps of: (a) providing a digital image of a badge holder; (b) generating an array of random numbers using a random number generator that employs a seed value; (c) combining the array of random numbers with the digital image to produce a modified digital image; (d) printing the modified digital image on the identification badge; and (e) recording the seed value on the badge.
