Embodiment Construction

[0014] The present invention introduces a file access system and its file access method, which can provide copyright protection for Internet information, which will be introduced in conjunction with specific drawings below.

[0015] figure 1 It is a structural schematic diagram of the file access system of the present invention. like figure 1 As shown, the system includes a client 100 and a file management center 200 , both of which are connected via the Internet 300 . The client 100 can be a desktop client or a mobile client, which further includes a random key generation module 102 , a random key storage module 104 , a decryption module 106 and a proxy processing module 108 . Wherein, the random key generation module 102 is a random number generator (random number generator), which is used to randomly generate a random key; the random key storage module 104 is used to store the generated random key, and the decryption module 106 further includes a second virtual A key gen...

Abstract

The invention relates to data communication and provides a file access system aiming at defect of unable to effectively protect internet information copyright of existing technology comprising client terminal, for randomly creating random key and store, transmitting data reading proxy embodying random key and access request; file management center, for receiving data reading proxy, searching and accessing file corresponding to access request, enciphering found file using dummy key created via random key, loading enciphered file in data reading proxy and transmitting to client terminal; clientterminal receiving data reading proxy, creating a dummy key through random key to decipher enciphered file. The invention also provides a file access method corresponding to the file access system. In present technical scheme, enciphered file is deciphered only when client requesting for the file uses, which guarantee non-authorized user can not use enciphered file and fully protect copyright.

Description

technical field [0001] The present invention relates to data communication, and more specifically relates to a file access system and a file access method thereof. Background technique [0002] The emergence of the Internet has accelerated the transmission of information and brought revolutionary changes to people's lives.
