A data file in a server apparatus is accessed through the network from the client apparatus and cached in the temporary storage, and the data file cached in the temporary storage is obtainable by the read apparatus for human recognition of the content of the data file. The read apparatus is not capable of at least one of printing and saving as. The present invention also provides a method of accessing a copy-prevented encrypted data file from a server apparatus. The system and method improve data file transmission security and decrease the possibility of copying and decrypting the data file.
