| Sumario: | Internet world is characterized by many users among which are crackers and thieves. Hence, the need for a secured system to safely exchange confidential information among users across the web is required. Of such tool is steganography that simply hides the user information under other kind of information such as image so that no one suspects that a sensitive data is being transferred. This paper presents a steganography scheme with an improved capacity and enhanced security by compressing the information before embedding it under an image. This is done by encoding the message before embedding it in the blue object of the cover image components (pixels). To prove this scheme, several testing are performed and results are compared. |
