Abstract:

Digital Steganography is a method used to embed secret message in digital images. Attackers make use of steganographic method for the purpose of transmitting malicious messages. In this paper, we proposed active warden method by using Prewitt filter on the input image to highlight the edge locations. Then the Discrete Spring Transform (DST) is applied on the filtered image to relocate the pixel location so that secret message cannot be recovered. This method is a generic method since it is independent of the steganography algorithms used and it does not require any training sets. We have compared our results with the existing system which used Sobel filter and curve length method. Our experimental results concluded that Prewitt was able to destroy the message to larger extent than by using Sobel filter and curve length method. Bit error rate (BER) and PSNR was used to measure the performance of our system. Our method was able to preserve the perceptual quality of the image.
