Yet existing DRM technology exists following deficiency:
1) user experience is relatively poor.User's complicated operation needs to install other extra software; Shielded digital resource is portable poor, and the user can not be transplanted to the resource of legal purchase other platform and use; The user can only browse but and can't process and use shielded audio and video resources, can not satisfy user's demand in actual use.
2) security is not high, protects and the imbalance competition that cracks.The Protector needs all information of safeguard protection digital resource and sends channel, and the cracker only need to break through one side in the protection system, obtains the copy of source file just so that the inefficacy of whole protection system.
3) versatility is not high.Dissimilar digital resource has different protected modes, provides the manufacturer of DRM numerous, so that the whole market falls apart.
