Abstract In Modification Direction Exploiting algorithm (EMD) exists binary information and multi-band data conversion redundancy problem, this paper proposed a new improved parallel algorithm. In this paper, we change the original EMD algorithm imbed function, and introduce the random safety parameter to improve the security of the algorithm. When 2n is equal to an integer power of 2, the algorithm does not have redundancy of data conversion problem, it can achieve the maximum theory embedding rate and the theory embedding efficiency. This algorithm utilizes multi-core parallel computing to improve operational efficiency. Therefore, the application of algorithm is more flexible and more efficient.
