碩士 === 國防大學 === 資訊管理學系 === 104 === We present a steganographic method that involves disrupting cover image pixel sequences through pseudo-random sequences. Before embedded secret data into cover image. We used a synchronized virtual random number generator that creating a secret key at first. Next phase, we can obtain a new image pixel sequence calculating secret key by algorithm. At last, the cover image is rearranged through this sequence and hiding secret data in plaintexts through the pseudo least-significant-bit method. Comparing with other steganography methods differently that we proposed method is disrupting the original image pixel sequence with a new sequence before hiding cover image based on one-time secret key and have had new pixel location each time when hiding secret data. We applied seven standard images including Lena to implement by Matlab. The experimental results show that our method can embed amount of secret data that still maintaining visual quality of the stego-image and promoting stego-image security. Also, the stego-image can also against RS and SPA detection.
