Personnel serving in India's Central Armed Police Forces (CAPFs) such as the Central Reserve Police Force (CRPF), Border Security Force (BSF), and Indo-Tibetan Border Police (ITBP) operate under high-stress conditions characterized by extended deployments in hostile environments, frequent transfers, family separation, and irregular working hours [PS, RESEARCHED]. Existing stress identification mechanisms rely heavily on manual observation and self-reporting, which often fail due to severe social stigma, fear of career degradation, and delayed administrative recognition [PS, RESEARCHED]. This dossier presents RakshakMind (or Project KAVACH), a privacy-preserving, AI-powered predictive personnel stress and welfare monitoring platform designed specifically for uniformed services. The system integrates anonymized HR operational data (leave patterns, deployment history, duty schedules, transfer frequency) [PS] with voluntary mobile-based self-assessments [PS] and optional wearable biometric metrics [PS]. Utilizing an explainable machine learning architecture (XGBoost/LightGBM with SHAP values) and strict Differential Privacy safeguards, the platform predicts early indicators of burnout, depression, and severe psychological distress [PS, INFERENCE]. It delivers aggregated, actionable unit-level insights to Commanders [PS] while routing individual early-warning alerts strictly to authorized, non-commanding Welfare Officers and Psychiatrists [PS, INFERENCE], transforming reactive crisis response into a proactive, non-punitive welfare framework [PS].
