1. A device comprising: a computer-readable memory storing specific computer-executable instructions; and a processor in communication with the computer-readable memory, wherein the processor executes the specific computer-executable instructions to cause the device to at least: receive a feature signature for a known composite image; receive a prior authorization determination for the known composite image, the prior authorization determination indicating that the known composite image may be transmitted in response to a search request received from another electronic device by a catalog system; receive an input image to be authorized for transmission via the catalog system, the input image comprising a background image region, an underlying image region, and an overlaid image region being overlaid upon at least a portion of the underlying image region; remove the background image region from the input image; generate an input image feature signature indicative of a shape of an item shown in the underlying image region; determine that the input image feature signature matches the feature signature; and upon determining that the input feature signature matches the feature signature, authorize the input image for transmission via the catalog system based at least in part on the prior authorization determination for the known composite image.
