Confidential computing is non-negotiable for senior safety tech because standard encryption fails during data processing, leaving biometric streams exposed. Health sensors generate continuous electrocardiogram (ECG), gait, and voice data, which constitute Protected Health Information (PHI) under HIPAA. Processing this data in traditional cloud environments, even with encryption-at-rest, requires decryption in memory, creating a critical attack surface. Secure enclave technologies, like those in AMD SEV or Intel SGX, perform computation on encrypted data, ensuring raw biometrics are never exposed, even to the cloud provider. This architecture is the only way to achieve true data sovereignty for sensitive elder care applications.
