摘要
A method of encryption features the steps of first encrypting a message and then hiding (embedding) it within a digital image carrier. This is accomplished by only slightly changing the gray levels of the image carrier. The changes are imperceptible to the human eye, because they appear as random thermal noise that is commonly present in digitized images.
