探討畫中畫印刷複製技術，對創作藝術品的真偽之影響

Effects of the Authenticity ofSteganography and PrintingReproduction Technology on CreativeArt

本研究探討從常見畫中畫隱藏技術中，選鬥雞眼立體法（隨機點立體法）、隱形油墨、紅外線隱藏技術、半色調隱藏技術四種方法，完成檔案製作後以數位印刷機印刷，印刷完後再將印刷品掃描再印刷，本研究主要是比較分析四種隱藏技術原檔印刷與掃描檔印刷後，隱藏資訊是否保留或產生變異，以此做為藝術畫複製印刷真偽之鑑定，經實驗結果隨機點立體法隱藏效果與半色調隱藏效果經掃描後都保留隱藏資訊，隱形油墨隱藏效果及紅外線隱藏效果經掃描後，隱藏資訊會消失不見，在不以增加額外成本考量上建議採用紅外線隱藏技術及半色調隱藏技術。

In this study, the four methods of painted in paintinghidden method.Invisible ink, infrared, and halftone hiddentechnology, the completion of archives printing, After theprinting scan is printed, this study is mainly comparableto analysis of the four hidden technical, original printingand copy printing authentic identification，Experimentalresults, Invisible ink, infrared hidden technology hiddeninformation will appear,SIRDS and halftone hiddentechnology hidden information will disappear, withoutincreasing additional cost consideration, adoption Infraredhidden technology and halftone hidden technology.
