Abstract

The invention relates to a significance area protection method based on an encryption image with visual meaning. The method is characterized in that a significance area is extracted via low-level feature of an image; a proper encryption scheme, which is designed by utilizing a chaotic encryption technology and / or an optical encryption technology, is used to preprocess the extracted significance area; and a random natural image is selected as a reference image, and the pre-encrypted image is converted into the encryption image with visual meaning. Key data of the image can be protected effectively.
