Abstract: A privacy-aware federated stress detection system (100) for adaptive incentive-based wearable healthcare learning is disclosed. The system (100) comprises a multi-modal bio-signal acquisition subsystem (102) configured to capture physiological and/or behavioural data associated with a user, and a data pre-processing module (104) configured to pre-process captured physiological signals for downstream analysis. A state estimation module (106) generates a local client state indicative of stress estimation, utility contribution, and privacy sensitivity, while a client state generator (108) generates composite client data. A privacy-preserving type encoder (110) encodes the composite data into a compressed privacy-preserving type signal for secure transmission to a central server. A server inference engine (112), an incentive score calculator (114), a contract engine (116), and a client selector (118) perform adaptive client scoring, contract assignment, and burden-aware client selection.
