| Outline of Final Research Achievements |
In an effort to achieve the protection of copyrights, privacy, and authenticity of digital images simultaneously, we studied a hybrid method with data hiding and block-permutation-based encryption in this research. Additionally, we also improved the accuracy for detection of the tampered area by a multiple information hiding technique and focused on effective key derivation schemes.
