Abstract
Images captured for components of a device are monitored for changes by evaluating a first region of interest in the images. Periodically, a command is sent to the device to move one or more of the components to a known position or state. A certain component or set of components associated with being moved based on the command is evaluated in a second region of interest in the images to determine if the corresponding component or set of components is in the known position or state within the images. When the corresponding component or set of components is not identified from the images in the known position or state, a security alert is raised for the device and security operations are processed on the host device.

(canceled)
A method comprising:
- causing a peripheral to move a component of the peripheral to a known position;
- comparing a determined position of the component as depicted in a real-time image against the known position;
- and
- performing a security action when the comparing indicated the determined position of the component depicted in the real-time image is not the known position for the component.
A method, comprising:
- instructing a component of a peripheral to move from a current state to a designated state;
- obtaining a real-time image of the peripheral once the peripheral confirms moving to the designated state;
- determining a replay attack is in progress on the peripheral when the real-time image does not depict the component in the designated state;
- and
- processing a security operation when the replay attack is determined to be in progress.
A system, comprising:
- a processor;
- memory coupled to the processor;
- and
- the processor configured to perform operations comprising:
- instructing a component of a peripheral to move from a current state to a designated state;
- obtaining a real-time image of the peripheral once the peripheral confirms moving to the designated state;
- determining a replay attack is in progress on the peripheral when the real-time image does not depict the component in the designated state;
- and
- processing a security operation when the replay attack is determined to be in progress
