摘要Lin and Lee proposed a document protection scheme which utilized a meaningful document to
cover the secret document. Although some researchers extended and improved their scheme, the main
drawbacks of Lin and Lee’s scheme are still left unsolved. The aim of our study is to propose a new document
protection scheme to solve these drawbacks. Instead of encoding the secret codes into index numbers, we
generate the cipher message through a series of comparisons between cheating codes and the logic operator
XOR. Compared with other studies, ours have the following advantages: firstly, the selection of the cheating
document needs not to be restricted to the character set of the secret document; secondly, the length of the
encoded file is the same as that of the secret document; thirdly, the codes of the cipher message are almost
uniformly distributed so is difficult to analyze without the key; fourthly, with the help of inner codes, our
scheme is applicable to documents in any languages; finally, our scheme performs efficiently and is easy to
implement.
