Abstract:	The wet paper codes method provides a good data embedding technique for secret data delivery. The WPC method applies matrix multiplications to determine modification locations in order to conceal secret data into a cover image. However, the WPC method is not suitable for low power computation environments. The proposed method applies pixel segmentation and exclusive-OR operation to achieve the goal of secret data delivery with lower computation cost than WPC's method. The recipient can successfully extract secret data from a stego image without knowing the locations of modified pixels. The experimental results show that the proposed method has larger embedding capacity than the WPC method with good visual quality. © 2009 IEEE.
