Of course, using steganography to communicate greatly reduces the risk of information leakage. 2. Only receiver can detect. 4) The secret can be in the form of a text or in the form of an image(i.e Hiding Text inside an Image or hiding Image inside an Image)-----Advantage Over Cryptography 1) The advantage of steganography over cryptography alone is that the intended secret message does not attract attention to itself as an object of scrutiny. It can also be defined as the study of invisible communication that is used to hide the existence of the communicated data in such a way that it remains confidential. Cryptography is the science of writing in secret code and is an ancient art[14] .Cryptography is necessary when communicating over any untrusted medium, which includes just about any network, particularly . Benefits of Steganography The main advantage of steganography is that it is easy to relay a message clandestinely without the knowledge of a third party. In this paper, the secret image is hidden in cover image using combination of LSB and DCT techniques. steganography and cryptography. In this paper, we present a novel image steganography method which is based on color palette transformation in color space. STEGAN-O-GRAPHY. INTRODUCTION Steganography and cryptography are both used to ensure data confidentiality. FB, outguess, stenghile and jstey are some of the algorithms used in steganography projects. • Avoiding communication in well-known forms greatly reduces the risk of information being leaked in transit. Steganography Seminar and PPT with pdf report: The term steganography is taken from the Greek language and it means the covered writing, it is an art of hiding the data within the innocuous carriers.In broad explanation, the steganography is mainly used for hiding the information within the images. Steganography Vs Cryptography 1024 Words | 5 Pages. The purpose of steganography is covert communication-to hide the existence of a message from a third party. A growing interest in the topic can be related to the many advantages that follow the use of a video file for hiding contents. Steganography has a huge advantage over standard cryptographic methods. Steganography has a critical advantage over cryptography: In cryptography, you know the secret message is there, only its content is concealed; in steganography, the existence of the secret . [1] Video Steganography. Classical Cryptography is independent of the medium of transmission, and hence can be used to transmit highly sensitive data over long distances. 1.1 A Brief Introduction to Steganography Steganography is the embedding of messages within an innocuous cover work in a way which can not be detected1 by anyone without access to the appropriate steganographic key. steganography techniques are increased by embedding multiple bits in a particular region selected either based on some image attributes or by Human Visual Perception. The obvious advantage of steganography is that you can hide a secret message in another message, be it text, image, audio, or whatever media you decide to hide your secret in. Steganography is done through various methods where some bit of image, video or other multimedia is replaced with plain text to create the ciphertext or . While these two processes are often performed separately, they can also be combined together to gain the advantages that come from both fields.If you wanted to hide the fact that communication was taking place, but also protect the message in case it was discovered, you could first encrypt it and then conceal it with steganography. are used . Often, using encryption might identify the sender or receiver as somebody with something to hide. The synopsis is also highlights the advantages of transform domain techniques over spatial domain and embed data in DWT domain. CHAPTER 1 INTRODUCTION Steganography, from the Greek.
