class HardwareAcceleratedDetector(fallback: PiiDetector, modelHash: String? = null, mlTimeoutMs: Long = 200) : PiiDetector
Optional NNAPI-backed PII detector wrapper.
Wraps a PiiDetector with hardware acceleration. NNAPI is present on all supported devices (minSdk 33 > 27). Falls back to fallback if NNAPI is unavailable or model integrity checks fail.
Security:
Model integrity: SHA-256 hash verification before loading (NIST SI-7).
Sandboxed execution: model cannot access network or filesystem.
FedRAMP AC-4/SC-7: no data transmission, local-only inference.
This is an OPTIONAL companion artifact (kiosk-ops-sdk-ml), not part of core SDK. The core SDK ships RegexPiiDetector as the default.
