A communication system includes: an image acquisition terminal to obtain a captured image, the captured image including at least one object that is captured with an imaging unit; a distributed data processing terminal to display the captured image; and a centralized data processing server connected with the distributed data processing terminal through a network. The image acquisition terminal includes: an object detector to detect the object in the captured image to generate a partial image that is a part of the captured image having the detected object; and a first transmitter to transmit the partial image to the distributed data processing terminal as data to be verified. The distributed data processing terminal includes: a second transmitter to transmit the data to be verified that is received from the image acquisition terminal, and verification data that is registered, respectively, to the centralized data processing server, the verification data being an image representing a specific object. The centralized data processing server includes: a verification unit to verify the data to be verified, using the verification data that is received from the distributed data processing terminal, to generate a verification result; and a third transmitter to transmit the verification result to the distributed data processing terminal, to cause the distributed data processing terminal to display information based on the verification result with the captured image.
