可逆式資料隱藏是目前被廣泛應用於保護影像的方法之一。後續有學者將浮水印的概念應用於資料庫中，以達到所有權保護或竄改證明。資訊安全管理系統(ISMS)最新版指引ISO 27002:2022中，也針對資料庫內敏感資料增加相關控制措施。為了確保資料的機密性與完整性，本論文改良直方圖位移技術，利用關聯式資料庫的欄位進行資料保護。透過嵌入影像或保護訊號，可以針對原始資料進行保護:當資料遭揭露時，非經授權者無法得知原始資料；當資料遭非法異動時，可以取出事先藏入之浮水印來宣告資料的所有權，或透過保護機制來偵測遭竄改之資料，並可無失真還原其餘資料。
根據實驗結果本論文之方法確實具有可行性。除了針對目前可逆式資料庫浮水印強韌性不足的缺點進行改善，另可提供公司或政府機構的資料庫資料保護上，符合ISO 27001:2022資料遮罩相關規範。

Reversible data hiding is currently one of the most widely used method to protect images. Some scholars applied watermarks to databases to achieve ownership protection or tamper proof. The ISO 27002:2022 also adds security controls about sensitive data in the database.
In order to ensure the confidentiality and integrity, the proposed approach is to improve the histogram shifting to protect the relational databases by embedding images or protecting signals. When the data is disclosed, the original data cannot be known; when the data are illegally altered, the watermark hidden in advance can be taken out to declare the ownership of the data, or the tampered data can be detected through a protection mechanism, and the restoring the rest of the data without distortion.
According to the experimental results, the proposed approach is indeed feasible. It can improve the shortcomings of the current reversible database watermarks. It can also provide companies or government with database data protection that complies with ISO 27001:2022 data mask related specification.
