    Abstract: In one aspect, an example method includes (i) obtaining video that depicts an area across multiple frames of the video, wherein the area is part of a scene of the video, and wherein the area is suitable for having an object inserted therein; (ii) detecting the area within the obtained video and determining area characteristic data associated with the detected area; (iii) determining scene attribute data associated with the scene; (iv) using at least the determined area characteristic data and the determined scene attribute data as a basis to select an object from among a set of multiple candidate objects; (v) inserting into the detected area the selected object to generate video that is a modified version of the obtained video; and (vi) outputting for presentation the generated video.

    Abstract: A physical camera provenance scoring system issues challenges to a source of video imagery that purports to include a physical camera. The challenges may include requests for camera metadata, requests to change camera parameters, requests to deploy specific camera capabilities, and requests for video imagery. The challenges are designed to elicit responses that can be used to determine a likelihood score that video imagery was captured by a physical camera as opposed to a virtual camera being deployed in an injection attack. The responses may be input to a machine classifier trained on imagery of known provenance to generate the likelihood score. The score may depend on the consistency of responsive camera metadata with received imagery, the behavior and end state of the video source in response to sequences of challenges, the ability of the video source to execute challenges, and the timing and computational load associated with challenge execution.
