Before revision:  To solve this dilemma, this paper develops a decentralized learning framework to enable proactive social care equipped with artificial intelligence and data protection. The proposed learning framework trains a secure local model for each user using their own datasets. Each user's device only shares its local model's parameters with the central model server without exposing any data, and the server integrates multiple users' models to learn a global data-free model .
