Abstract: 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.
