Abstract
Conventional authentication schemes that use fragile watermarks can often lead to irreversible image distortion. Therefore, reversible authentication (RA) schemes, which do not lead to the introduction of distortion, have become increasingly popular. However, existing RA schemes need the help of third-party services for tamper localization or content recovery, and hence are not completely blind, which may result in inconvenience and insecurity of the authentication procedure. Motivated by this issue, a new RA scheme is proposed using the prediction-error expansion and compressed sensing reconstruction techniques. The proposed scheme achieves basic authentication in a reversible way, and implements tamper localization and content recovery without any third-party dependency. Experimental results demonstrate the proposed scheme has better performance compared to other state-of-the-art RA schemes.
