Image Watermarking Using LSB (Least Significant Bit)
With the rapid development and wide use of Internet, information transmission faces a big challenge of security. People need a safe and secured way to transmit information. Digital watermarking is a technique of data hiding, which provide security of data. This paper presents a watermarking technique which least significant bits (LSB), its steps and its process with matlab images.
متن کاملAn Efficient Method for Image and Audio Steganography using Least Significant Bit (LSB) Substitution
In order to improve the data hiding in all types of multimedia data formats such as image and audio and to make hidden message imperceptible, a novel method for steganography is introduced in this paper. It is based on Least Significant Bit (LSB) manipulation and inclusion of redundant noise as secret key in the message. This method is applied to data hiding in images. For data hiding in audio,...
متن کاملComparison of fingerprint enhancement techniques through Mean Square Error and Peak-Signal to Noise Ratio
Abstract— In the fingerprint recognition system the main goal of the fingerprint enhancement algorithm is to reduce the noise present in the image. There are several factors that affect the quality of the acquired fingerprint image viz. presence of scars, variations of the pressure between the finger and acquisition sensor, worn artifacts, and environmental conditions during acquisition process...
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 کاملLsb Modification Based Steganography Using Digital Image System by Transform Algorithm
Steganography is the science that deals with conveying secret information by embedding into the cover object invisibly. In steganography, only the authorized party is aware of the existence of the hidden message to achieve secret communication. The image file is mostly used cover medium amongst various digital files such as image, text, audio and video. The proposed idea of this research work i...
