Abstract

This invention provides a trade system of contribution articles, which enables information gathered by many people to be efficiently used in the mass media such as a newspaper or a magazine. First, the contributor photographs an image of an accident or the like using a contributor terminal 7. Besides, position verification information of the accident locale is acquired from a position verification authentication server 3. Then, the image information of the accident or the like and the position verification information are registered into a contribution market server 13 by the contribution terminal 7. A person in charge at the mass medium operates a mass medium terminal 11 to access to the contribution market server 13, and finds out articles for which purchase priority is to be acquired. For example, when knocking down the purchase priority by the auction, the contribution market server 13 extracts an investigator in the vicinity of the locale of the accident or the like for the corroborative investigation, and transmits them to the mass medium terminal 11. The investigation request is transmitted to an investigator terminal 9 of the investigator. If there is no problem in the corroborative investigation, a purchase procedure is carried out. Incidentally, the contributor can set a condition concerning a selling destination and/or a sum of money, and according to that, a successful bid is determined.
