 In both Android and iOS platforms, there are native and third-party solutions to check application integrity, such as [iOS App Attest](https://developer.apple.com/documentation/devicecheck/establishing-your-app-s-integrity), and [Android Play Integrity](https://developer.android.com/google/play/integrity). It's the application developer’s responsibility to incorporate the integrity check feature and respond promptly to potential hacks.
 
 Azure liveness detection implements safeguards against untrustworthy runtime environments. The liveness detection SDK provides a digest of its liveness detection service calls, which can be passed to the application integrity APIs.
