Traditional　centralized　digital　copyright　protection　is　weak　in　security　and　difficult　to　manage.　In　order　to　protect　digital　assets　from　unauthorized　use　and　to　solve　the　centralized　regulatory　challenges,　blockchain　technology　is　used　to　enhance　the　protection　of　digital　works　copyrights.　This　paper　proposed　a　digital　works　copyright　protection　architecture　based　on　the　Consortium　Blockchain,　and　elaborate　on　the　security　problems　and　solutions　faced　by　the　architecture.　Moreover,　the　Diffie-Hellman　algorithm　is　improved　based　on　the　Shamir　algorithm　to　make　it　more　suitable　for　the　characteristics　of　blockchain.　Finally,　a　smart　contract　is　written　according　to　the　characteristics　and　process　of　digital　copyright　protection,　and　a　Fabric-based　digital　copyright　protection　solution　is　implemented.　The　feasibility　and　effectiveness　of　using　blockchain　for　digital　copyright　protection　proposed　in　this　paper　are　proved　through　experiments,　Furthermore,　the　extensibility　of　the　solution　is　discussed.　©　2021,　Springer　Nature　Singapore　Pte　Ltd.
