英文摘要：

A Parallel Least Significant Bit（PLSB） algorithm is proposed, which realizes the embedding and ex-tracting of the QR code watermark. The image data is divided into blocks and the tasks are shared by the com-piling and guiding instruction of Open MP, which realizes the parallelization of computing process. The QR codeimage embedded in the watermark method has a better security verification function and is suitable for saving inthe electronic form. The time cost of the parallel processing method is about 1/3 less than that of the traditionalserial algorithm.
