Abstract: <P>PROBLEM TO BE SOLVED: To provide a method of hiding data which improves confidentiality and which can bring close to the quality of an image of a display of an original image before embedding as much as possible, even if it is the case that the amount of data of a key image is large.  <P>SOLUTION: Multi-band original data are pretreated, and a reversible wavelet transformation of each principal component data after the pretreatment is performed to at least one. The key data are embedded to the high frequency component of the principal component data after the reversible wavelet transformation, a congruence quadrature wavelet inverse transformation of the principal component data is performed after embedding the key data, and the principal component inverse transformation is performed and the multi-band data for circulation is formed. Accordingly, the original data are divided into the principal component data for every energy. Principal component data embedding key data can be selected. While being unable to know to which the principal component data key data are embedded from the viewpoint of a third person but being able to raise confidentiality, and as contrasted with the original data, the quality of image can be maintained by embedding the key data to appropriate principal component data.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
