Abstract

The present invention discloses a digital contents encoding and decoding system and the method thereof. The system and the method both adopt the device id of a content reader module, the account number of a user, and the data of the expiring date to real time encode digital contents. And when decoding, the reader module is used to decode the encoded digital contents into original digital contents with the device id, the account number and the time data at that instant. With the implementation of the invention, digital contents can be, safely and difficult to break, encoded and decoded in real time to effectively protect the digital contents from unauthorized approaching or acquiring.
