This study concerns on the steganography in MS Excel document and proposes a new steganographic method hiding information efficiently by text-rotation technique. The proposed method is implemented by slightly rotating the angle of the text inside the cell to reduce the visible detection of the embedded information. Measuring the text angle of the cells retrieves the secret information. Experiments for different threshold in the algorithm are presented and the results show the proposed method not only has a good imperceptibility but also achieve high embedding rate while most of cells in Excel document are short in length.]]>Provos, N. and P.
