Abstract: With the increase in the number of elderly people in the world, the problem of population aging has gradually become prominent. People are paying more and more attention to the elderly, and medical supplies for the elderly have also attracted great attention. At present, various intelligent medical boxes have appeared in the domestic and foreign markets. These medicine boxes mainly include functions such as setting time, reminding to take medicine regularly, and SMS notification service. This project designed an intelligent medicine box, which is based on 80C51 single-chip microcomputer, loaded with infrared on-beam sensor, three-axis acceleration sensor, short message module, and Bluetooth module. The main functions of the system include intelligent detection module, timing reminder function, short message notification module and anti-fall detection module. On the one hand, the intelligent system can monitor and remind the elderly to take medications in time. On the other hand, it can also monitor the personal safety of the elderly alone at home. This is different from the current intelligent medical box on the market and is also the highlight of the system.

Abstract: Blockchain is now widely used in various industries due to its openness, transparency, autonomy, imtamability, decentralization, and traceability. With the wide application of blockchain technology, its security problems have also brought significant challenges, seriously affecting the implementation of blockchain applications. Data on the traditional blockchain is open to the entire network node. The update operation of data records is also transparent, accompanied by the leakage of user information. Although blockchain has the characteristics of anonymity and privacy, with its development, it has not been easy to meet users' needs. How to effectively protect user data privacy, realize data sharing on the blockchain, and ensure the security of data integrity, transmission efficiency, storage efficiency, and application is very important to break through the bottleneck of the development of blockchain technology and promote its application. This paper proposes a traffic data resource access control scheme based on blockchain technology by combining the attribute encryption access control system based on ciphertext strategy based on blockchain's distributed ledger technology and the openness and imtamability it brings. In this scheme, the task of attribute encryption is to ensure the security involved in the process of plaintext and ciphertext conversion and the efficiency of data sharing, and to implement a one-to-many access sharing policy, to enhance the safety of the access sharing system and improve the efficiency of the access control module. This paper introduces the access control mechanism from two aspects of system architecture and the access sharing process. Then the attribute encryption mechanism is designed. The design process includes symbol description, primary structure, algorithm design idea and algorithm construction. Finally, the functionality and security of the access control mechanism are analysed.
