In this paper we have proposed an LSB based data hiding method. Here, first cover image is encoded by LBP based method (call as ELBP). In ELBP method, a 3 x 3 block is encoded by k bits (1 aek ae9) respect to the central pixel. For data hiding purpose, the cover image is encoded by ELBP then r (1 aer < k) bits are embedded into each neighbor pixel by replacing least r bits of the encoded stream and then modified pixel is processed by OPAP method to improve the quality of the stego image. Proposed method gives high quality stego images with higher embedding rate compare to the state-of-the-art methods. The security of the proposed data hiding method is tested against the attacks like RS steganalysis and Chi-square attack and these methods fail to detect hidden data.
