Steganography An Art of Hiding Data
In today’s world the art of sending & displaying the hidden information especially in public places, has received more attention and faced many challenges. Therefore, different methods have been proposed so far for hiding information in different cover media. In this paper a method for hiding of information on the billboard display is presented. It is well known that encryption provides secure ...
متن کاملSteganography- A Data Hiding Technique
Steganography is the art of hiding information and an effort to conceal the existence of the embedded information. It serves as a better way of securing message than cryptography which only conceals the content of the message not the existence of the message. Original message is being hidden within a carrier such that the changes so occurred in the carrier are not observable. In this paper we w...
متن کاملLSB Steganography Based Reversible Data Hiding
-This paper introduces a new, principled approach to least significant bit (LSB) steganography in digital signals such as images. It is shown that privacy protection of medical images with information using histogram shifting based reversible data hiding.First of all, the patient’s privacies need to be preserved.Therefore, embedding secret data into the medical images would be one of the useful...
متن کاملData Hiding: Steganography and Copyright Marking
Communicating in secure way is, in general, synonymous of encrypting the traffic, but this is not really true in practice. If a person wants to comunicate a secret to another one is better hiding the message in an innocuos object as a mp3, mpeg and a jpg. This paper presents an overview of information hiding in general, steganography and copyright marking in particular. Several techniques to hi...
متن کاملAdaptive Image Steganography by Reversible Data Hiding
An adaptive steganographic scheme is proposed in this paper. The adaptive quantization embedder is introduced and employed by block-wised fashion. We also constructed contrast-correlation distortion metric to optimally choose quantization steps for image blocks to guarantee more data being embedded in busy areas. Different form existing methods, our scheme embeds the AQE parameters together wit...
