Novel steganographic method based on jig swap puzzle images

چکیده
bstract. A new steganographic method for data hiding in jig swap uzzle images is proposed. First, a color image is taken as input and ivided into blocks. Second, each block is rearranged to a new poition according to the secret data and a stegokey. The resulting mage is a perfect jig swap puzzle. The original image is needed for xtracting the secret data. Under the assumption that the receiver nd the sender share some common images, the receiver can exract the secret data from the jig swap puzzle image. We also resent a scenario for secret data transmission based on an online ig swap puzzle. Experimental results show that the proposed ethod is undetectable and robust under lossy image compression nd format conversion. 2009 SPIE and IS&T. DOI: 10.1117/1.3073979

Clustering-Based, Fully Automated Mixed-Bag Jigsaw Puzzle Solving
The jig swap puzzle is a variant of traditional jigsaw puzzles, wherein all pieces are equal-sized squares that must be placed adjacent to one another to reconstruct an original, unknown image. This paper proposes an agglomerative hierarchical clustering-based solver that can simultaneously reconstruct multiple, mixed jig swap puzzles. Our solver requires no additional information beyond an uno...
متن کاملA Novel Technique for Steganography Method Based on Improved Genetic Algorithm Optimization in Spatial Domain
This paper devotes itself to the study of secret message delivery using cover image and introduces a novel steganographic technique based on genetic algorithm to find a near-optimum structure for the pair-wise least-significant-bit (LSB) matching scheme. A survey of the related literatures shows that the LSB matching method developed by Mielikainen, employs a binary function to reduce the numbe...
متن کاملEncryption based LSB Steganography Technique for Digital Images and Text Data
Digital steganography is the art and science of hiding communications; a steganographic system thus embeds secret data in public cover media so as not to arouse an eavesdropper’s suspicion. A steganographic system has two main aspects: steganographic capacity and imperceptibility. However, these two characteristics are at odds with each other. Furthermore, it is quite difficult to increase the ...
متن کاملRamses: a Visual Steganographic System
Steganography is the art of “secret communication”. Its goal is to transmit a message (information) hidden inside another visible message. The typical visible message used in many steganographic systems is a digital image and the embedded message is usually hidden by working in the Fourier domain. In this paper we present Ramses, a novel approach to the steganography based on the Puzzle Image M...
