In contrast to traditional electronic books, augmented reality books provide readers with the chance to explore supplementary information or multimedia content associated with the material they are reading. Unlike typical electronic books, augmented books encompass a wider range of content levels. This highlights the necessity for a specialized authentication framework designed to handle the diverse levels of content found in augmented books. Within this paper, we introduce an innovative, object-based, multi-level content authentication framework crafted to meet practical requirements. Its purpose is to aid lawful users in confirming the legitimacy of the augmented books they are perusing, effectively distinguishing between legally copyrighted editions and pirated reproductions. Finally, the conventional LSB substitution method is employed to demonstrate the functionality and applicability of our proposed object-oriented, multi-level content authentication framework.
