METHODS AND SYSTEMS FOR PSEUDORANDOM BATCH CODE PRINTING AND PRODUCT AUTHENTICATION

Pseudorandom batch code printing and product authentication systems and methods are described comprising a batch code printing application (app) for generating an authenticating sequence of authentic pseudorandom numbers by inputting an initial seed value into a cryptographic algorithm to output an initial authenticating pseudorandom number in the authenticating sequence. A second alphanumeric code is generated based on a second authenticating pseudorandom number of the authenticating sequence. A printer is controlled to print a first pseudorandom batch code comprising the first alphanumeric code on a first product and a second pseudorandom batch code comprising the second alphanumeric code on a second product, where the first and second products are part of a product batch. An authentication app determines an identified product date and a suspect alphanumeric code from a suspect batch code as printed on a suspect product, and generates one of: (1) an authenticating output, or (2) a counterfeit output.
