由於數位技術的蓬勃發展，各種多媒體之著作，如音樂、電影、照片，隨著數位化與嵌入式系統的進步而散播快速，然而伴隨而來的是著作內容保護不易。多創意內容被數位化且形成可攜式的產品，如MP3隨身聽、掌上型數位電視、數位相框、電子書。但是在種種創作中，藝術繪畫之內容保護隨著高密度液晶螢幕之發展，數位藝術繪畫之保護亦漸形重要。
本論文結合二階層H.264無失真影像壓縮、基於直方圖的可回復式資料隱藏、以及可回復式可見式浮水印等技術，結合浮水印、資料隱藏、影像壓縮等理論技術以保護數位藝術繪畫，並於德州儀器DM6446 單系統晶片系統(SoC)實現數位畫框系統，不僅達到可攜，強調無失真地呈現，同時也達到保護數位內容的效果。

Under the fast development in digital technology, multimedia content creations, such as music, movies , and photos, which were hard to duplicate and deliver in the past, become easier to be distributed and played due to digitalization and the invention of system on chip (SoC). However, this trend also introduces the problem in protecting digital contents in personal MP3 player, handheld video player, digital photo album, and electronic book. Furthermore, the protection of digital art paintings also become more important when the high density LCD displayers are successfully developed.
In this thesis, we integrate two-layer H.264 lossless image compression, histogram-based data hiding, and recoverable watermarking techniques to design a protected lossless digital painting system. In the same time, we realize this digital painting system on TI DM6446 DVEVM. With the proposed system, we achieve a portable, lossless, and low cost digital painting display system, which can effectively protect the content of digital arts.
