One of the issues that arise in the text steganography is the capacity of hiding secret bit. Focusing in Arabic text steganography we propose a sharp-edges method to encounter the issue. This new method will hide the secret bits in the sharp-edges for each character in the Arabic text document. The main processes involved are identifying sharp-edges in the cover-text, secret message preparation...

High transmission efficiency, low resource occupancy and intelligible meaning make text message as the most commonly used type of media in our daily communication. Text steganography, an information hiding technology based on text message, has been a new exploring research in recent years. Due to the restriction of redundant information as well as its alterability in manual operation, text mess...

ABSTRACTThis paper presents a method of hiding the text message watermark into audio. This hiding technique is called amplitude modification in low bit encoding. The message embedded into higher LSB layers to increase the robustness. The technique is implemented in matlab since it is a language for data analysis and numerical computation. This proposed scheme includes dynamic coding approach fo...

Reversible Data hiding is a process of hiding information into a cover image. There are various techniques used for hiding secret data. Audio, video, image, text, and picture can be used as a cover medium in data hiding. In images, Reversible Data Hiding (RDH) is a method which is very helpful in the recovery of original cover after the inserted message is extracted. This vital method is broadl...

Steganography is an art of hiding the information without any change in the external appearance of the cover object. Cryptography is a technique to make the information unreadable for unauthorized users. Making the data unreadable and hiding it, will make the data highly secure. Image steganography allows the user to hide a large amount of data inside an image. On transmission side Steganograph...
