Abstract

Proposes a method to embed a signature seal in a picture under an orthogonal wavelet transform. Three parts of a multi-resolution representation are expressed in a vector and are related to each other. The maximum and minimum values among the entries in the vector are obtained, and the absolute value of the difference between them is used for controlling the embedding of the seal. When the seal is needed, one can extract it from the picture. It is clear from the presented experimental results that the seal does not prevent one from seeing the picture comfortably. Therefore, it seems that this method could be used for signing one´s name in multimedia
