Abstract: A living body search system includes an unmanned moving body and a server. The body includes: a camera; image data processing for retrieving image data; moving means; and communicating. The server includes: a database configured to record therein search data; and notifies a client. The body and the server are connected to each other through a communication network. The system includes individuals in the image data wherein individual identification information records the database to determine whether the candidate object in the image data is a searched-for object. The system registers, in the server, searched-for data provided in advance from the client. The system compares image data retrieved from the camera with the individual identification information to perform individual recognition. When the image data matches the individual identification information, the system determines that the object has been found. Then, the system notifies the client that the searched-for object has been found.
