-------------------------------------------------------------------ABSTRACT-----------------------------------------------------------------Data hiding is the art of embedding data into digital media in a way such that the existence of data remains concealed from everyone except the intended recipient. In this paper, we discuss the various Least Significant Bit (LSB) data hiding techniques. We ...
Digital watermarking has attained a position of overwhelming interest in image processing research as a new method of protecting multimedia content from unauthorized copying, as the informal transmission and manipulation of digital data creates intimidation for inventors and providers. This paper presents a new watermarking system employing five bit LSB strategy for copyright protection of imag...
Video Steganography to embed Image is an art and science of hiding images by embedding images within the video file, seemingly harmless images. An encrypted image or files may still hide information using steganography, so even if the encrypted file is deciphered, the hidden message is not seen. The LSB approach is used along with the MaskingFiltering and Transformations techniques to hide the ...
A wide range of steganography techniques has been described in this paper. Beside the evaluation of embedding parameters for the existing techniques, two problems -weaknessesof substitution techniques are investigated which if they could be solved, the large capacity strengthof substitution techniques would be practical. Furthermore, a novel, principled approach to resolve the problems is prese...
This paper is an extension of our work on stego key search for JPEG images published at EI SPIE in 2004. We provide a more general theoretical description of the methodology, apply our approach to the spatial domain, and add a method that determines the stego key from multiple images. We show that in the spatial domain the stego key search can be made significantly more efficient by working wit...
Security is the main concern in today’s world due to the rapid growth of information technology. In this research work, the steganographic is the method or process in which the useful information or data, concealing into another form such as image, text, audio and video. The main concern in this work is to provide the confidentiality, availability, integrity and authenticity of information. In ...
In this paper a novel steganographic method has been proposed to improve the security of embedded data with high capacity and imperceptible visual quality, the proposed method is based on four-pixel block differencing, modified LSB substitution and Knights tour. Secret data is embedded randomly using knights tour in each 8×8 pixels block of cover image and n-bit modified LSB substitution has be...
Data hiding is the art of hiding data for various purposes such as; to maintain private data, secure confidential data and so on. There are lots of techniques used for data hiding and the well known technique is the Steganography. Steganography is one of the most powerful techniques to conceal the existence of hidden secret data inside a cover object. Images are the most popular cover medium us...
In recent years, due to the powerful abilities to deal with highly complex tasks, the artificial neural networks (ANNs) have been studied in the hope of achieving human-like performance in many applications. Since the ANNs have the ability to approximate complex functions from observations, it is straightforward to consider the ANNs for steganography. In this paper, we aim to implement the well...
This paper proposes an improved LSB(least Significant bit) based Steganography technique for images imparting better information security .It presents an embedding algorithm for hiding encrypted messages in nonadjacent and random pixel locations in edges and smooth areas of images. It first encrypts the secret message, and detects edges in the cover-image using improved edge detection filter. M...
