Abstract-This paper presents a Secured Wireless Sensor

monitors human health, activities, and shares information among doctors, care-givers, clinics, and pharmacies in the Cloud, so that users can have better care with low cost. SC3 incorporates various technologies with novel ideas including; sensor networks, Cloud computing security, and activities recognition.1 I. MOTIVATION AND PROPOSED ARCHITECTURE In recent years, Wireless Sensor Networks (WSNs) have been employed to monitor human health and provide life care services. Existing life care systems simply monitor human health and rely on a centralized server to store and process sensed data, leading to a high cost of system maintenance, yet with limited services and low performance. For instance, Korea u-Care System for a Solitary Senior Citizen (SSC) monitors human health at home and provide limited services like 24 hours×365 days safety monitoring services for a SSC, emergency-connection services, and information sharing services. In this paper, we propose a Secured WSN-integrated Cloud computing for u-Life Care (SC3) which monitors not only human health but also human activities to provide low-cost, high-quality care service to users
