| Abstract: | DES algorithm puts safety of all in keyword.It is a perfect method to realize bar code encrpytion which has low cost and simple algorithm etc. Based on DES encrpytion techniques, the system for the generation and automatic identification of two-dimensional bar code PDF417 was designed. The use of encrpytion technology effectively prevents the information from being stolen and changed, it has the effect of encryption and avoiding forgery and overcomes the shortcomings of information deposited on the normal two-dimensional bar code which can easily uncovered and copied and improvs the safety and reliability. Therefore it can greatly meet the special information safety requirement of regions. |
