Considering that binary texts featured complicated texture and weak immunity, the problem of how to embed the watermark into the binary text is investigated and a new algorithm that combines DWT (Discrete Wavelet Transform) and DCT (Discrete Cosine Transform) domain is proposed in this paper.

Aiming at the binary text image’s characteristics of simple pixel, complex texture and bad immunity of information con-cealment, a digital watermarking embedment location choosing method has been put forward based upon compatible roughness class.
