In network steganography methods based on packet length, the length of the packets is used as a carrier for exchanging secret messages. Existing methods in this area are vulnerable against detections due to abnormal network traffic behaviors. The main goal of this paper is to propose a method which has great resistance to network traffic detections. In the first proposed method, the sender embe...
Image watermarking refers to the process of embedding an authentication message, called watermark, into the host image to uniquely identify the ownership. In this paper a novel, intelligent, scalable, robust wavelet-based watermarking approach is proposed. The proposed approach employs a genetic algorithm to find nearly optimal positions to insert watermark. The embedding positions coded as chr...
This paper presents a new stenographic scheme based on matrix embedding using BCH syndrome coding. The proposed method embeds massage into cover by changing some coefficients of cover. In this paper defining a number :::as char:::acteristic of the syndrome, which is invariant with respect to the cyclic shift, we propose a new embedding algorithm base on BCH syndrome coding, without finding ro...
