摘要：

A　high-definition　digital　color　image　watermark　algorithm　based　on　QR　code　and　DWT　is　studied　in　this　paper.　The　basic　concept,　theoretical　framework　and　the　application　domain　of　the　digital　watermark　algorithm　is　introduced.　From　the　simulation　results,　this　algorithm　can　achieve　better　universality,　and　can　be　applied　to　most　of　the　color　images.　Watermarked　digital　works　can　achieved　better　quality,　and　the　embedded　watermark　is　difficult　to　be　detected.　In　addition,　the　extracted　two-dimensional　code　image　can　achieve　a　high　quality,　and　can　be　scanned　through　the　electronic　equipment　and　the　information　in　it　can　be　acquired.　©　2015　IEEE.
