數位浮水印（Digital Watermark）技術是指用信號處理的方法在數位化的多媒體資料中嵌入隱蔽的標記，這種標記通常是不可見的，只有通過專用的檢測器或閱讀器才能提取。隨著數位浮水印技術的發展，數位浮水印的應用領域也得到了擴展，數字浮水印的基本應用領域是版權保護、隱藏標識、認證和安全不可見通信。本研究主要是以頻率域的數位圖像訊號處理技術為基礎，在MATLAB環境下，通過系統程式設計的方式，建立並實現基於DCT演算法的數位浮水印加密檢測驗證系統。該系統設計主要包含數位浮水印的嵌入與提取，模擬結果驗證分析，數位浮水印演算法具有有效性、可靠性、抗攻擊性、強韌性和不可見性，能夠為數位媒體資訊在防偽、防篡改、認證、保障資料安全和完整性等方面提供有效的技術保障

Digital watermark technology refers to the use of signal processing methods to embed hidden marks in digital multimedia materials, which are usually invisible and can only be extracted by special detectors or readers. With the development of digital watermarking technology, the application fields of digital watermarking have also been expanded. The basic application fields of digital watermarking are copyright protection, hidden identification, authentication and secure invisible communication. This research is mainly based on the digital image signal processing technology in the frequency domain. In the MATLAB environment, through the method of system programming, a digital watermark encryption detection and verification system based on DCT algorithm is established and realized. The design of the system mainly includes the embedding and extraction of digital watermarks, the verification and analysis of simulation results. Provide effective technical guarantees in terms of anti-counterfeiting, anti-tampering, authentication, and data security and integrity.
