Taking advantages of transparent encrypt, which is based on the windows file system filter driver, the file trajectory is tracing as follows: the file is unable to be accessed once the tracing file is taken out of the working security domain.

The tracing system will record all information about the operations on the file, besides log of the submission to the server. According to the processes above, the file trajectory is tracing on time, and hence can put an end to the dangerous operations. It is convenient to analyze and audit the results.
