In　this　paper　we　propose　a　new　method　that　could　reveal　some　traces　that　were　left　in　the　tampered　digital　images　without　using　watermarking　technique.　Our　method　is　based　on　detecting　the　presence　of　feather　operation,　which　is　particularly　useful　to　create　a　smooth　transition　between　the　selected　region　and　its　surroundings.　The　similarity　of　pixel　neighborhood　is　used　as　weight　coefficient　to　modulate　local　entropy　value.　The　forged　region　can　be　determined　by　the　value　of　weighted　local　entropy　precisely.　Results　of　experiments　on　tampered　images　will　be　given.
