Healthcare management using blockchain technology refers to the use of blockchain to improve the efficiency, security and privacy of healthcare data management. Blockchain enables the creation of a decentralized, tamper-proof database that can be shared among healthcare providers, patients, and other stakeholders. This can enhance the coordination and sharing of healthcare data, streamline the administrative processes, reduce costs, and improve patient outcomes. This abstract provides an overview of healthcare management using blockchain, highlighting its benefits and challenges, as well as its potential applications in healthcare. The major reason that paves way for the exploration of blockchain in health care management is its capabilities to secure the information’s from cyber-attacks, fraud, and unauthorized access and allow an equitable and transparent data management without the need for a central authority or intermediary, making sure that patients have greater control over their own data. This method can also enable the secure exchange of health data between different healthcare systems and providers, promoting interoperability and improving patient care, by removing the need for intermediaries, blockchain can help streamline the administrative processes, reducing costs and improving the efficiency of healthcare delivery and tracking of medical products and devices throughout the supply chain, helping to prevent counterfeiting and ensuring patient safety. Overall, the use of blockchain in healthcare management has the potential to improve the quality of care, reduce costs, and increase patient satisfaction. However, there are also challenges to be addressed, such as regulatory compliance, interoperability, and scalability.
With the major growth in roadways, there is a raise in the number of toll booths. These toll booths have lengthy queues, the time consumed in paying cash and returning change causes additional delay. In this paper, a system uses Radio Frequency Identification (RFID) technology, ARM LPC2148, GSM, relay and computer host. RFID is used to obtain the vehicle number. RFID card with unique id is mounted on every vehicle, data contain on the card is examined by the RFID scanner placed at the toll gate. If the vehicle belongs to authorized person or registered, fixed money is automatically deducted from the owners account, message will be send to registered mobile number and automatically toll gate is opened. In this project Rs.50 is deducted for car and Rs.100 is deducted for bus. If the account balance becomes insufficient then buzzer is alarmed, message will be sent to the owner that she/he has insufficient balance and should use manual toll payment. If the vehicle belongs to higher officials such as VIP, police, army, ministers or ambulance the toll gate is opened automatically and the amount is not deducted. For upcoming situation all vehicle information that passes the toll will be stored. Stolen vehicle directory is also present, if the card number of the vehicle matches then buzzer is alarmed, message will be sent to the registered police station, amount is deducted from owner's account and gate is opened. The advantage is that message is sent both to the owner and police station. Coding is done in Embedded C. This system eliminate the manual cash handling, reduces traffic congestion and help in lesser fuel utilization. This makes automatic toll collection more convenient for the public use.
