1. A method of labeling and authenticating a product for anti-counterfeiting purposes, the method comprising:

  • generating original product identification data referring to the product;

    encrypting the original data to generate encrypted product identification data;

    storing the original data and the corresponding encrypted data in a database system;

    labeling the product with the encrypted data during a packaging process;

    authenticating the product by;

    reading the encrypted data;

    transferring the encrypted data to a data processing system;

    decrypting the encrypted data in the data processing system to generate decrypted product identification data;

    comparing the decrypted data with the stored original data;

    determining whether the decrypted data matches the original data, thereby generating an authentication result;

    incrementing an authentication counter of the original data by one and storing the authentication counter; and

    if the authentication result is positive and the authentication counter is less than or equal to a predetermined threshold, providing information that the product is genuine;

    or if the authentication result is positive and the authentication counter is above the predetermined threshold, providing information that the product is not genuine;

    or if the authentication result is negative, providing information that the product is not genuine.
