Analysis of LSB based image steganography techniques
But practical implementation of the definition is not feasible, so pragmatic approach would be to make the algorithm as strong as possible. Steganography is most widely formulated in terms of the prisoner’s problem where Alice and Bob are two inmates who wish to communicate in order to hatch an escape plan. However, all communication between them is examined by the warden, Wendy, who will put t...
متن کاملChaotic 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 کاملAn Image Inpainting Technique Based on the Fast Marching Method
Digital inpainting provides a means for reconstruction of small damaged portions of an image. Although the inpainting basics are straightforward, most inpainting techniques published in the literature are complex to understand and implement. We present here a new algorithm for digital inpainting based on the fast marching method for level set applications. Our algorithm is very simple to implem...
متن کاملLSB Based Audio Steganography Using Pattern Matching
Security of the digital information is becoming primary concern prior to transmitting the information itself via some media. Information security means protecting information and information systems from unauthorized access, use, disclosure, disruption, modification or destruction. In this proposed method, the carrier file and the secret message are taken into audio format and a pattern matchin...
متن کاملSegmentation Using Fast Marching Method
The paper deals with a novel segmentation technique applicable to colour video sequences. The algorithm uses Fast Marching Method for automatic extraction of semantic objects from natural colour video sequences by joint motion and colour analysis. The algorithm handles background in the same way as other objects, thus it does not need global motion compensation. The number of control parameters...
