Corona 19 minimizes face-to-face contact, and online untact platforms are emerging in the medical sector. However, there are potential risks of medicine expiration, medicine misuse, and responsible materials management for secure delivery. In this paper, we investigate three key functional requirements for online pharmacy, and design the blockchain based online pharmacy to meet the requirements. To protect the patient''s privacy and to ensure tamper-free traceability, we incorporate the multi-level access authentication scheme for each participant (governments, medical circles, and patients). We show that our system guarantees patient’s privacy without further system modification.
