Introduction:
Due to fast growth of Internet applications, digitized data becomes more and more popular. Because of the property of digitized data, easy to duplicate and modify, the researches of information security become prosperous.
The techniques of cryptography and steganography are usually used in privacy communication.
The term of Steganography comes from the Greek words, ‘stegano’ and ‘graphia’, and means “covered writing” which is usually interpreted to mean hiding information in other information.
Existing System
Microsoft PowerPoint is a ubiquitous presentation program and widely used by businesspeople, researchers, and educators
Animations are applied on text, images, or other elements and appear on a slide at timed intervals or with a mouse click.
Disadvantages
Message is hard to recover if image is subject to attack such as translation and rotation
Significant damage to picture appearance. Message difficult to recover.
Relatively easy to detect, as our project has shown.
Image is distorted. Message easily lost if picture subject to compression such as JPEG.
Conclusion
In this presentation, we have proposed a steganography method to show the performance of the proposed method.
In contrast to other steganography methods, our method does not distort the PowerPoint file and can naturally hide information.
