| This article which is based on the analysis of field of Information Security and the research of field of Digital Image Processing, try to develop a system to score Encode Images'robust. With Agility Method and Extreme Programming, we successfully develop an experimental system to score Encode Images.In field of Information Security, encode and decode are always a contradiction. Because code is a positive direction procedure, which is lower difficult and resource is more abundant, developer is less qualified. And because decode is a reverse direction procedure, which is more difficult and need more technique and experience, decoders are always advanced developer. In this condition, there is a big gap between encoder and decoder, maybe hard encode but easy decode.The new of this article is: do not think from algorithm but from to build a expert system to help the developer who are not skilled in this field, to flatten the big gap between encoder and decoder, to lower the development's cost.Under the comprehensive research and generalization of Digital Image Processing, we got the general procedure about Digital Image Processing. Based on the general procedure, following the Agile Method and Extreme Programming, applying the recursive procedure composed by require analyze,framework design,coding, finally we got a experimental,stable,opened score platform. We checked the theory by practice.We used this system to check some representative images on the web, we could got a conclusion that most encode images is easy to decode. Without right theory they can't build a robust encoded image. And through thorough experiments by this platform I have concluded such points: single alpha encoded is useless, we must encode all characters as whole; confusion points are useless, we must use confusion lines which look like stroke; enlarge base of character such as Chinese Character, not only digital number and alpha. |
