Information Hiding using Least Significant Bit Steganography and Blowfish Algorithm
Security is the most challenging aspects in the World Wide Web. In present time information sharing and transfer has increased exponentially. So to find out best solution this is providing necessary protection of our data against malicious attacks from intruders. Cryptography and Steganography are the two major techniques for secret communication. Cryptography converts information from its orig...
متن کاملInformation Hiding Using Least Significant Bit Steganography and Cryptography
Steganalysis is the art of detecting the message's existence and blockading the covert communication. Various steganography techniques have been proposed in literature. The Least Significant Bit (LSB) steganography is one such technique in which least significant bit of the image is replaced with data bit. As this method is vulnerable to steganalysis so as to make it more secure we encrypt the ...
متن کاملEnhancing the Least Significant Bit (LSB) Algorithm for Steganography
Various Steganography algorithms have been proposed and implemented for hiding the existence of data in a cover object starting from the algorithms that work in transform domain to the ones that work in spatial domain, such as Least Significant Bit (LSB), which uses the three colours (RED, GREEN and BLUE) present in an image. Three colours are present in the pixel of an image, therefore, this p...
متن کاملAn Enhanced Least Significant Bit Steganography Technique
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 ...
متن کاملOffensive Algorithm for Hiding and Extracting Information Using Image Steganography
In this paper we will study the various image based steganographic techniques for information hiding, analyze the problem in them and will propose a novel steganographic algorithm namely ‘An offensive algorithm for hiding and extracting information using Image Steganography’ for hiding information within the spatial domain of 24-bit color image and as well as extracting it. The motivation for t...
