Abstract: According to the storage format and features of icon and bitmap resource, a new information hiding scheme based on PE resource is proposed. The scheme utilizes the imperceptibility of Portable Executable(PE) file to embed secret information into PE resources datum by applying information hiding algorithms. As a result, it enhances the information imperceptibility and capacity. In addition, a new palette redundant color allocating algorithm is proposed, which can improve the embedding capacity of information hiding algorithms based on palette color redundancy.

Key words: Portable Executable(PE) file, information hiding, Least Significant Bit(LSB) algorithm
