Secure services and hardware on a mobile device are disabled if it is detected that software in the untrusted domain, such as the operating system, has been hacked or tampered with. Mobile devices often have rich, unprotected operating systems which are vulnerable to hacking, especially from execution of one or more apps. These apps are separated from secure services on the device, such as e-wallet services, NFC functionality, camera, enterprise access, and the like, and the present invention ensures that tampering with code in the untrusted domain or operating system does not affect these and other secure services. If tampering in the untrusted space is detected, the secure services and possible hardware on the device are shutdown or disabled. The extent of this disablement may depend on various factors, such as use of the device, type of device, context in which device is used (e.g., military, enterprise). |
