Biometrics based Steganography using Circular Folding in DWT Domain
Steganography is the art and science of hiding or embedding data in a transmission medium. The goal of steganography is to hide an information message inside a harmless cover medium in such a way that it is not possible even to detect that there is a secret message. In this paper, the object oriented steganography is based on biometrics. Data is embedded into some regions of the skin and not to...
متن کاملBiometrics Security using Steganography
A biometric system is at risk to a variety of attacks. These attacks are intended to either avoid the security afforded by the system or to put off the normal functioning of the system. Various risks have been discovered while using biometric system. Proper use of cryptography greatly reduces the risks in biometric systems as the hackers have to find both secret key and template. It is notified...
متن کاملLiterature Survey on DWT Based Image Steganography
Steganography is the science of secure communication which has received much attention from the scientific community recently. The four main objectives of steganography are: Indefectibility, Security, embedding payload, and Robustness. However, steganography can protect data by hiding it in a cover object but using it alone may not guarantee total security. Thus, the use of encryption in stegan...
متن کاملA DWT Based Approach for Image Steganography
In this paper we propose a new steganography technique which embeds the secret messages in frequency domain. According to diferent users’ demands on the embedding capacity and image quality, the proposed algorithm is divided into two modes and 5 cases. Unlike the space domain approaches, secret messages are embedded in the high frequency coefficients resulted from Discrete Wavelet Transform. Co...
متن کاملA New Hybrid Method for Colored Image Steganography Based On DWT
Data transmission security has become an extremely important field of research. Steganography is an art of hiding information in image, audio and video files in a way that would meet the security requirements in the form of overt or covert. In this study, we propose a new hybrid steganography technique for color images that hide secret messages in the frequency domain of a cover image's blu...
