The device and method in order rendering to do the user data

摘要

This invention regards the device and method in order rendering to do the user data. In order inside PC with during transfer to offer the protection for the hacking of the data of high level, this method following to this invention, it is proposed. This method re-was encoded, using step and the said key data which receive with the user data and the key data which are encoded by drive 2 the step which decodes the said user data, using the re-encoding key, the said from step and the said drive 2 which re-encode the user data which is decoded the said the step which transmits with the user data and the said re-encoding key which re-are encoded, using the said re-encoding key for application unit 3, the said the step which decodes the user data which re-is encoded, the said the step which reproduces the user data which is decoded to the application data and the step which re-encodes the said application data, the saidThe application data the step which is transmitted to the said drive 2 from the said application unit 3, the step which decodes the application data which is encoded, the said the application data which is decoded the step which step, and the said application data which are transmitted to rendering unit 4 from the said drive 2 rendering is done is included.
