Title: Holger Zellmer: Innovator in Security Elements
Introduction
Holger Zellmer is a notable inventor based in Magdala, Germany. He has made significant contributions to the field of security elements in imaging technology. With a total of 3 patents, his work focuses on methods that enhance the authenticity and security of images.
Latest Patents
Zellmer's latest patents include a method for producing security elements in an image that are not visible to the human eye and cannot be copied. This innovative approach is particularly useful for verifying the authenticity of images. The method involves imaging through a halftone, where individual image dots are arranged adjacent to each other. A unique feature of this method is the definition of at least one field with a random geometric shape or freeform within the image. By manipulating the image dots in this field, encrypted information is stored for comparison with a database, while the serial number is displayed through contours formed in the halftone.
Another significant patent involves a method for reading a code stored in a halftone image and comparing it with a retrievable value. This method checks the authenticity of products by analyzing an image of the product. The proof of authenticity remains invisible to the human eye and cannot be copied. The code, stored in the halftone image, can be read using an optical device and compared with a value in a database. This process also includes determining a part of a serial number that describes its structure and a hash function used for transmitting the serial number.
