However, information is communicated over an open channel. An attacker may intercept, replay, or modify this information. Therefore, many authentication schemes are proposed to provide secure communication for TMIS. Recently, Yu et al proposed a privacy-preserving authentication scheme in the Internet of Medical Things(IoMT)-enabled TMIS environments. They emphasize that their scheme is resistant to various attacks and ensures anonymity. Unfortunately, this paper demonstrates that Yu et al's scheme is vulnerable to impersonation attacks, replay attacks, and tracking attacks and cannot mutually authenticate. To overcome the shortcomings of Yu et al's scheme, we mainly improve the authentication and key agreement process and propose a corresponding improved scheme. We also compare the improved scheme with several existing authentication schemes in terms of security and computational efficiency.展开更多

Sources of information： The reference articles were mainly selected from the CNKI, Wanfang Database, PubMed, Science Direct and other resources. Following a systematic, comprehensive search of databases, a total of 1 062 qualitative, quantitative or mixed studies were initially selected; after careful review and screening, 45 studies were coded and analysed. Inclusion criteria： The articles were selected using the words ＂diabetic＂, ＂type 2 diabetes＂, ＂telecare, telenursing, remote care or telernedicine＂, ＂outcomes or effect＂ and ＂influencing factors＂. Type 2 diabetic who were intervened by electronic equipment are included. The patients who just have typel diabetes are excluded, and those who were treated without using electronic equipment also are excluded. Results： Telecare produces positive results with a variety of outcomes, such as an improvement in the overall status of patients with type 2 diabetes, making full use of the medical staff resources and promoting the popularity of the hospital remotely; however, the factors which may prevent the development of telecare are various. Conclusions： Telecare has a positive effect in all aspects. With the development of technology and gradual changes in the people＇ s concept of e-health, telecare may have a brilliant future and may play a more important role in promoting human health.展开更多

Nowadays, there are several techniques that attempt to address this problem by 3D mapping with a high computational cost. This paper describes software algorithms that can detect the persons in the scene and analyze different actions and gestures in real time. The motivation of this paper is to create a system for thetele-assistance of elderly, which could be used as early warning monitor for anomalous events like falls or excessively long periods of inactivity. We use a method for foreg-round-background segmentation and create a feature vectorfor discriminating and tracking several people in the scene. Finally, a simple real-time histogram based algorithm is described for discriminating gestures and body positions through a K-Means clustering.展开更多
