Meanwhile, we have to see that some illegal manufacturers make large amount of fake and shoddy commodities flooding in the sale chain of market in order to obtain high profits. It has caused the country, the enterprise and the consumers suffered serious losses. This paper combined the algorithm thought of Data Encryption Standard (DES) with two-dimensional (2D) bar codes technology, applied in keeping secret and forgery-proof of product sales management, overcame the shortcomings that the information of ordinary two-dimensional bar codes is easy to be deciphered and duplicated, improved the security and the reliability of the information of two-dimensional bar codes, provided the powerful technical support for enterprise cracking down on fake and shoddy commodities.
