Abstract

Nowadays with the proliferation of readily available image content, image hiding has become a topic of very importance. In many applications, it is desirable to embed identifying images for authentication. This paper presents a novel digital image-hiding scheme based on blending technology in the frequency domain. The digital image blending is first introduced, and then the concept of digital image blending is generalized to the DCT domain. The properties of DCT blending are also studied. With these properties of the DCT blending, a novel digital image-hiding scheme is presented. The experimental results show that the scheme can be expediently realized and it is robust in a certain extent. The scheme also can be used in digital watermarking.
