AN ENCRYPTED TRANSMISSION METHOD AND EQUIPMENT SYSTEM FOR PREVENTING COPYING THE DATA RESOURCE

摘要

An encrypted transmission method and equipment system are provided. The method includes the following steps: a client equipment sends a file downloading request of the data file to a network server; the network server transmits a corresponding invoke request to a data server; the data server transmits the corresponding data file to the network server; after making a third layer encryption to the data, the network server transmits the encrypted data file to the client equipment via the network; after receiving the data file, the client equipment decodes the data file. The said equipment system includes a network end equipment and a client end equipment, wherein the said client end equipment includes a decode device and a reader; the said network end equipment includes an encrypt device and a data file storage, the said encrypt device encrypts the file, and transmits the encrypt key to the client end equipment. This invention advances the transmission security of the data file effectively and decreases the possibility that the data file is copied and decoded.
