摘要：

This　paper　presents　a　novel　color　medical　image　authentication　scheme　based　on　QR　Factorization　and　Dual　Pseudorandom　Circular　Chain　(DPCC).　The　red　component　and　the　green　component　of　the　color　image　possess　more　brightness　than　the　blue　one,　so　QR　Factorization　values　of　the　red　component　and　the　green　component　are　used　to　be　the　initial　values　of　logistic　mapping　to　generate　two　watermarks.　Then,　the　Least　Significant　Bit　(LSB)　plane　of　blue　component　by　the　watermarks　is　replaced　according　to　DPCC.　Experimental　results　show　that　the　proposed　algorithm　is　sensitive　to　malicious　attacks　on　the　watermarked　image,　and　can　localize　the　tampered　region　accurately.　©2009　IEEE.
