The authors have already proposed a data embedding method based on the phase modulation of sampling lattice. Considering the diversity of the image information, the trade-off property between the robustness of the embedded data and the image quality is desired to be closely controllable. In our method, the degradation of image quality is minimal even when additional data can be embedded. Also, the trade-off property above-mentioned can easily and continuously be controlled with a single parameter. Furthermore, since the original image is required as a reference signal for decoding, decoding and falsifying the additional information by a third party is made very difficult by concealing the original image. This paper discusses the decoding error rate for still image for the three kinds of the encoding signal processing methods used in our method. As a result, we conclude that the band-limited interpolation and cubic spline interpolation give better performance, compared with the bi-linear interpolation.
