The encryption algorithm of commodity production number for data encryption is proposed

which is based on double chaotic map system..In the encryption process

After we take the two-dimensional logistic map and Henon map together for the number of commodity production of scrambling encryption

we obtained the anti-counterfeit of commodity.Meanwhile

the performances under the double chaotic map are analyzed.Utilize the pseudo-randomness and initial value sensitivity and ergodicity characteristic of the double chaos map

The results show that double chaotic map have the good properties of cryptographic.which makes constructing algorithm more complex

key space of algorithm will be bigger and its harder to break into this cryptosystem

As a result

the goods process of commodity circulation have a stronger function of anti-counterfeiting.
