The invention discloses a method and a system for digital copyright protection. According to the method and the system, a copyright protection policy is firstly set through a copyright data protection processing device, a common data file is encrypted by a key and then converted into the data file under copyright protection; an inquiry is then initiated according to copyright data ID of the data file under copyright protection through an authorized file generating device in order to obtain the key and the protection policy, and a user characteristic code is used to encrypt the key and the protection policy to obtain an authorized file; through an authorized file application device, the keys and the protection policy in the authorized file are restored to a key plaintext and a protection policy plaintext which can be directly used by a copyright data protection application device; and in the end, the decrypted and restored copyright data is transmitted to an application system through the copyright data protection application device and an application system interface. By means of the method and the system, the breaking of attackers can be effectively prevented in order to realize the protection for digital copyright.
Description
