A Lightweight Quantum Blockchain-Based Framework to Protect Patients Private Medical Information

Electronic medical information is becoming increasingly popular. Electronic medical information includes sensitive and private information. The medical information must be protected from intruders during the communication with patients. During the exchange of information, blockchain technology can secure information from intruders. There are several traditional methods for protecting electronic medical information. These approaches can communicate data accurately but are vulnerable to collective and coherent attacks. These protocols also require higher communication and computation costs. This study proposes a Lightweight Quantum Blockchain-based Framework to safeguard patient medical information across multiple hospitals. This framework can withstand quantum computer attacks. Additionally, the proposed protocol requires less communication and computation costs as compared to the existing protocols.
