Authenticating interface element interactions

An access control system is provided for preventing implicit granting access to privacy-related functions on an electronic device. Software-based events that grant access to device functions may be verified by confirming that the software event corresponds to a hardware input event. The verification prevents replacement of user interface inputs that can be used to fraudulently grant access to a particular function. 提供一种用于防止暗中准予对电子设备上的隐私相关功能的访问的访问控制系统。准予对设备功能的访问的基于软件的事件可通过确认该软件事件与硬件输入事件相对应来校验。该校验防止可用于欺诈地准予对特定功能的访问的用户界面输入的顶替。
