  • Scrambling method of the data files
    Patent number: 6829614
    Abstract: The data scrambler converts the original data files into the converted data files, respectively, while keeping the output produced by the receiver unchanged. The conversion may comprise dummy insertion, logical structure changing, tag name changing, element order changing, and value unit changing. If the input data files are XML and XSL files, each step also produces XML and XSL files. However, the produced files contain different data from the input XML and XSL files.
