A Steganography Implementation based on LSB & DCT
In recent years, Steganography and Steganalysis are two important areas of research that involve a number of applications. These two areas of research are important especially when reliable and secure information exchange is required. Steganography is an art of embedding information in a cover image without causing statistically significant variations to the cover image. Steganalysis is the tec...
متن کاملAn Analysis of LSB & DCT based Steganography
This paper presents analysis of Least Significant Bit (LSB) based Steganography and Discrete Cosine Transform (DCT) based Steganography. LSB based Steganography embed the text message in least significant bits of digital picture. Least significant bit (LSB) insertion is a common, simple approach to embedding information in a cover file. Unfortunately, it is vulnerable to even a small image mani...
متن کاملAn Optimized FPGA Implementation of LSB Replacement Steganography Using DWT
This work focuses on the image steganography with an image compression using Discrete Wavelet Transform (DWT) on FPGA Spartan III Evaluation Development Kit (EDK). Current trends support digital image files as the cover file to hide another digital file with secret message or data. At receiver side, using Inverse Discrete Wavelet transform, both original image as well as hidden data can be succ...
متن کاملAn Implementation of LSB Steganography Using DWT Technique
Steganography is the art or practice of concealing a message, image, or file within another message, image, or file. In steganography, there is a technique in which the least significant bit is modified to hide the secret message, known as the least significant bit (LSB) steganography. Least significant bit matching images are still not well detected, especially, at low embedding rate. In this ...
متن کاملData Security Using LSB & DCT Steganography In Images
Abstract Steganography is a technique of hiding information in digital media. In contrast to cryptography, it is not to keep others from knowing the hidden information but it is to keep others from thinking that the information even exists.In this paper, we propose a LSB & DCT-based steganographic method for hiding the data. Each bit of data is embedded by altering the least significant bit of ...
