The DRM client system comprises at least one application plug-in module, for generating a DRM client processing request according to a user's request or an external application system's request; and a DRM information processing module for receiving digital data and decrypting the received digital data, in response to the DRM client processing request from the application plug-in module, wherein the DRM information processing module determines and selects a DRM rule to be adopted according to the contents of the DRM client processing request and the digital data and executes a corresponding decryption operation on the digital data according to the selected DRM rules. According to the present invention, a uniform DRM platform can be provided for all existing DRM systems and enables any application systems to have DRM functions through the DRM client system (the uniform DRM platform) and the method thereof according to the present invention.
