SIGNATURES AND LABELS IN A BLOCKCHAIN DERIVED FROM DIGITAL IMAGES

A computer implemented method for generating at least one security label (110) using at least one printing device (112) is proposed. The method comprises the following steps:i) (114) generating a first digital image (116) comprising a plurality of colored pixels by printing a printer job with a prin...

Zusammenfassung:	A computer implemented method for generating at least one security label (110) using at least one printing device (112) is proposed. The method comprises the following steps:i) (114) generating a first digital image (116) comprising a plurality of colored pixels by printing a printer job with a printer control setting and scanning the printout using the printing device (112) thereby generating a digital fingerprint;ii) (118) providing a binary code (120) of identifier information;iii) (122) mapping the identifier information with the digital fingerprint by determining a binary code of the digital fingerprint and adding the binary code (120) of the identifier information to the color code of the first digital image (116);iv) (124) generating a second digital image (126) having a plurality of colored pixels different from the first digital image (116) by transferring the added binary codes into a color code of the second digital image (126);v) (128) printing the second digital image (126) on a substrate (129) thereby generating the security label (110).
