Amino Acids and Biogenic AminesGS to PVCS is proved and shown by means of giving theoretical analysis and conducting some specific schemes. The relationship between codebook and computational complexity are analyzed for PVCS and RGS. Furthermore, the contrast of PVCS is no less than the one of RGS under the same access structure, which is shown by experimental results.

What Sustains Life? An Overview,imate performance when both the investigator and the forger have complete information. Finally, for a more practical scenario that one of the parties has incomplete information, a Bayesian game is introduced and the ultimate performance is compared with that of complete information game.

0302-9743 l-Forensics and Watermarking, IWDW 2013, held in Auckland, New Zealand, during October 2013. The 24 full and 13 poster papers, presented together with 2 abstracts, were carefully reviewed and selected from 55 submissions. The papers are organized in topical sections on steganography and steganalysis

Cheating Immune Block-Based Progressive Visual Cryptography which any two dishonest participants might collude together to tamper their image blocks shared with other honest participants. Also, they can impersonate an honest participant to force other honest participants to reconstruct the wrong secret. In this paper, we solve the cheating problem and propose a cheating immune (2, .)-BPVCS.

Bitspotting: Detecting Optimal Adaptive Steganographyher to consider all positions. We give defining formulas for each player’s best response strategy and minimax strategy; and we present additional structural constraints on the game’s equilibria. For the special case of length-two binary sequences, we compute explicit equilibria and provide numerical

Improved Algorithm of Edge Adaptive Image Steganography Based on LSB Matching Revisited Algorithmr. Experimental results demonstrate that our improved EAMR (I-EAMR) can efficiently defeat the targeted steganalyzer presented by Tan .. [.]. Furthermore, it can still preserve the statistics of the carrier image well enough to resist today’s blind steganalyzers.
