In this paper, a data hiding algorithm based on PLHaar transform is proposed. The PLHaar transform maps an n-bit integer to another n-bit integer, and it guarantees no underflow/overflow to occur. Secret information is embedded into the LSB's of the PLHaar transform coefficients. Although the proposed algorithm has a slight decline in the quality of the stego audio compared with the algorithm based on Haar transform, it can recover the embedded secret information correctly without any additional operation.
