| 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. |
