Abstract: A system for interface and/or device user identity verification comprises a user device with a user interface and a camera, a system controller in communication with the user device and a databank. The databank comprises a stored image for each user as well as input command types associated therewith and requiring real time image identification. When a real time user command is inputted via the user interface and corresponds to a stored input command type, the stored image associated therewith is identified and a real time image of the real time user is captured via the camera. The system determines whether the captured image corresponds to the identified stored image. The real time input command is allowed to be executed if the captured image corresponds to the identified stored image and is prevented from being executed if the captured image does not correspond to the identified stored image.

Abstract: Apparatus and methods for extending functionality of memory controllers using a loopback mode for testing are disclosed herein. In one aspect, a processor-based device provides a memory access intercept circuit configured to receive a memory write request that is directed to and received by a memory controller. The memory access intercept circuit transmits proxy write data to the memory controller, and intercepts write data directed to the memory controller for the memory write request. The memory access intercept circuit stores the write data in a write data buffer, and, upon intercepting the proxy write data from the memory controller directed to a physical (PHY) interface circuit, retrieves the write data from the write data buffer and transmits the write data to the PHY interface circuit. The memory access intercept circuit subsequently receives, from the PHY interface circuit, loopback data, and stores the loopback data in a read data buffer.
