## Summary

With the development of Internet of Things (IoT) technologies in recent years, there has been a significant increase in the deployment of smart devices in various environments. These devices aim to enhance the quality of human life in a cost-efficient manner. One crucial application of IoT technology is the implementation of smart homes for elder healthcare. These homes not only enable elders' health to be monitored and taken care of effectively but also provide them with a comfortable and independent living environment. However, despite the numerous benefits offered by smart homes for elder healthcare, there is a potential risk to elders' privacy due to non-fully protected network communication. In this paper, the authors present a Privacy Deduction Scheme (PDS) that demonstrates how elders' privacy can be substantially exposed through eavesdropping on sensor traffic from a smart home. The PDS utilizes deductions made from an attacker's perspective to identify elders' movement activities and speculate on sensor locations within the smart home. By analyzing real sensor datasets from smart homes, the experimental results showcase the effectiveness of PDS in deducing and disclosing elders' privacy. This research highlights the importance of protecting elders' privacy within smart homes as malicious attackers could exploit this information to endanger both their well-being and property. The findings emphasize the need for enhanced security measures in IoT-based applications for elder healthcare to ensure that sensitive data remains confidential and secure.
