Abstract: A computer-implemented method of collecting data, the method including: collecting pieces of metadata associated with pieces of image data from a plurality of moving objects that hold the pieces of image data; and determining, when a specific piece of metadata that satisfies a condition is found in the collected pieces of metadata, based on information for making collected numbers of the pieces of image data close to be an equalized value and a map that manages the collected numbers in a mesh shape, whether to request transmission of a specific piece of image data with which the specific piece of metadata is associated to a specific moving object from which the specific piece of metadata is collected.

Abstract: An information processing apparatus includes a memory and a processor coupled to the memory. The memory is configured to store therein information in association with a specific service. The information specifies another service called in response to a request for using the specific service. The processor is configured to receive a request for using a first service provided by a server. The processor is configured to acquire information stored in the memory in association with the first service. The processor is configured to notify the server of the acquired information together with the received request.
