Abstract: The present invention provides a DRM method and system for supporting offline sharing of digital resources. When a client applies for joining in a domain, the client sends its own device information to a server, and obtains feature data of the domain by receiving a sharing certificate sent by the server. Wherein, the sharing certificate is created by encrypting the feature data of the domain by using the equipment information of the client as a cipher. The client decrypts the sharing certificate by using its own equipment information to obtain the feature data. Since the feature data has already been obtained in the procedure of applying for joining the domain, a client is able to use the digital resources by using the feature data even if the client cannot connect to network, thus, an advantage of supporting offline sharing of digital resources is achieved.
