Chaotic Map Based Random Image Steganography Using LSB Technique
Steganography play an important role to transfer secret data over insecure network. Moreover digital images are taken as a cover to communicate the sensitive data. One of the simplest approach of embedding the secret data into cover image is Least Significant Bit (LSB) method. This paper aims to propose a new symmetric key based image hiding technique. Pseudo random keys are generated by using ...
متن کاملSLSB: Improving the Steganographic Algorithm LSB
This paper presents a novel steganographic algorithm based on the spatial domain: Selected Least Significant Bits (SLSB). It works with the least significant bits of one of the pixel color components in the image and changes them according to the message’s bits to hide. The rest of bits in the pixel color component selected are also changed in order get the nearest color to the original one in ...
متن کاملA New Steganographic Algorithm Based on Multi Directional PVD and Modified LSB
Steganographic techniques can be utilized to conceal data within digital images with small or invisible changes in the perceived appearance of the image. Generally, five main objectives are used to assess the performance of steganographic algorithms which include embedding capacity, imperceptibility, security, robustness and complexity. However, steganographic algorithms hardly take all of thes...
متن کاملA steganographic method for digital images with four-pixel differencing and modified LSB substitution
To improve the embedding capacity and provide an imperceptible visual quality, a novel steganographic method based on four-pixel differencing and modified least significant bit (LSB) substitution is presented. The average difference value of a four-pixel block is exploited to classify the block as a smooth area or an edge area. Secret data are hidden into each pixel by the k-bit modified LSB su...
متن کاملImage Sterilization to Prevent LSB-based Steganographic Transmission
Sterilization is a very popular word used in biomedical testing (like removal of all microorganisms on surface of an article or in fluid using appropriate chemical products). Motivated by this biological analogy, we, for the first time, introduce the concept of sterilization of an image, i.e., removing any steganographic information embedded in the image. Experimental results show that our tech...
