A novel data embedding method using random pixels selecting

Data hiding is an effective technique in multimedia security. With regard to the fact that when carrying information, the data hiding algorithm was liable to be detected by statistical steganalysis tool, a novel data embedding method using random pixels selecting was proposed. This method embedded data by using multilevel histogram shifting technique. In the embedding process, random pixels in natural images were selected to be used to hide data. Therefore, the embedded data distributed in a more irregular manner and can better evade the detection of statistical steganalysis tool. Moreover, the proposed method obtained better stego image quality. In comparison to another similar work, the proposed method provided better security while offering low distortion. © 2013 Asian Network for Scientific Information.
