Rather than searching for the holy grail of steganography, this paper presents the basis for development of a tool kit for creating and exploiting hidden channels within the standard design of network communications protocols. The Alice and Bob analogy, derived from cryptology, is used to present network protocols in a way that more clearly defines the problem. Descriptions of typical hidden ch...

Voice over IP (VOIP) is an upcoming technology that enables voice communication through the Internet. Packet-based network link shared between different connections, which give rise to interaction between various traffic types. This paper focus is on improving the data embedding capacity of steganography in low bit rate audio streams encoded by G711 source codec and to overcome the packet loss ...

Steganography is the science of communicating in the hidden manner. This paper presents a robust and secured Image Steganography method capable of embedding high volume of text information in digital cover-image without incurring any perceptual distortion. The method is based on compression and encryption. In order to achieve high capacity, dictionary based lossless compression techniques are u...

Abstract: In [4], we had proposed a new technique for secret communication of a digital image through a network exposed to attackers by combining two popular information security techniques: Cryptography and Steganography. We used a modified version of AES for encryption which uses a key stream generator (W7) and four techniques for steganography (one in spatial and three in frequency domain) w...

in this paper, a faster method for embedding cryptographic information in the image ispresented by expressing the concept of latent prints (steganography). data is encrypted bytwo methods before embedding to increase reliability. then they are embedded into the imageby a button, a method has been expressed to reduce potential noise impact on the wayinformation is encoded.

Steganography is one of the methods of secret communication that hides the existence of hidden message. It can be defined as the study of invisible communication that usually deals with the ways of hiding the existence of the communicated message. The hidden message may be text, image, audio, video, etc. The files can be a cover image after inserting the message into the cover image using a ste...

Authentication mechanisms are at the forefront of defending world from various types cybercrime. Steganography can serve as an authentication solution through use a digital signature embedded in carrier object to ensure integrity and simultaneously lighten burden metadata management. Nevertheless, despite being generally imperceptible human sensory systems, any degree steganographic distortion ...

Steganography is a technique for the secure transmission of data over the network. In this process, the secret information is transmitted by hiding this behind a signal or image or video. Steganography can be a solution which makes it possible to send news and information without being censored and without the fear of the messages being intercepted and traced back to us. In this process, the se...

Message transmission through internet as medium, is becoming increasingly popular. Hence issues like information security are becoming more relevant than earlier. This necessitates for a secure communication method to transmit messages via internet. Steganography is the science of communicating secret data in several multimedia carriers like audio, text, video or image. A modified technique to ...

Steganographic techniques allow users to covertly transmit information, hiding the existence of the communication itself. These can be used in several scenarios ranging from evading censorship to discreetly extracting sensitive information from an organization. In this paper, we consider the problem of using steganography through a widely used network protocol (i.e. HTTP). We analyze the stegan...
