A High Capacity Email Steganography Scheme using Dictionary

The main objective of steganography is to conceal a secret message within a cover-media in such a way that only the original receiver can discern the presence of the hidden message. The cover-media can be a text, email, audio, image, and video, which can be transmitted through a public channel, such as the Internet. By extending the use of email among Internet users, the provision of email steg...

Steganography Scheme Based on Reed-Muller Code with Improving Payload and Ability to Retrieval of Destroyed Data for Digital Images

In this paper, a new steganography scheme with high embedding payload and good visual quality is presented. Before embedding process, secret information is encoded as block using Reed-Muller error correction code. After data encoding and embedding into the low-order bits of host image, modulus function is used to increase visual quality of stego image. Since the proposed method is able to embed...

Detection of perturbed quantization (PQ) steganography based on empirical matrix

Perturbed Quantization (PQ) steganography scheme is almost undetectable with the current steganalysis methods. We present a new steganalysis method for detection of this data hiding algorithm. We show that the PQ method distorts the dependencies of DCT coefficient values; especially changes much lower than significant bit planes. For steganalysis of PQ, we propose features extraction from the e...

Multimedia based Steganography using PMM and M4M

In today’s highly digitalized world maintaining the secrecy of the secret data is a vital problem. Steganography is an emerging area which may be used for secure transmission of the digital data. It is the art and science of embedding data into different covers such that the data embedded is imperceptible. The covers that can be used cover all forms of digital multimedia object namely text, ima...
