| Abstract: | Firstly,information encryption and hiding techniques are briefly presented and a new method that optimizes information encryption technique is put forward.In the method,the secret information is hided with unique encryption key and first compressed then hided.Furthermore,a kind of easy information embedding algorithm is designed and infor-mation hiding and resuming processes are completely introduced.Finally,this paper completes a system of hiding com-pressed information in image.The system proves that the method of hiding compressed information in image is effective and practical. |
