This paper presents a method of information hiding based on the digital-position information, bringing forward an augmented identity matrix and a definite arithmetic upon it. In this method, if the single digital-position information is used, embedding efficiency can achieve m when n = 2m -1. And if the multi-digital-position information is used, data embedding rate can almost reach 1 when n is big enough, with the condition of an unchanged embedding efficiency. So more information can be hided in the host information with same bits and it can be used in stream multimedia, hidings with great information, etc. The proposed method with low computing complexity can be realized easily. Satisfying experimental results are gained on PC and LAN
