In this paper, a novel and efficient authorization and authentication Digital Rights Management (DRM) s chema is proposed firstly for secure multimedia delivery, then based on the sche ma, a real-time digital signature algorithm built on Elliptic Curve Cryptograph y (ECC) is adopted for fast authentication and verification of licensing managem ent, thus secure multimedia delivery via TCP/RTP can efficiently work with real -time transaction response and high Quality of Service (QoS) . Performance eval uations manifest the proposed schema is secure, available for real-time media s tream authentication and authorization without much effected of QoS. The propose d schema is not only available for Client/Server media service but can be easily extended to P2P and broadcasting network for trusted rights management.展开更多

Methods The relevant literature was searched, and the differences of licensed pharmacists system at home and abroad were compared. Results and Conclusion By comparison, it is found that there are obvious differences in the management system, access system and continuing education of licensed pharmacists between China and foreign countries. In order to improve the system of licensed pharmacists in China, the supervision of licensed pharmacists should be strengthened by introducing relevant laws and regulations as soon as possible. Besides, the admittance criteria of licensed pharmacists should be enhanced, and the continuing education system of licensed pharmacists should be optimized as well.展开更多
