1. A method for verifying geographical descriptiveness of a media file, the method comprising:
- storing, in a first storage medium, a media file and data indicating an assigned geographical position for the media file;
sending said media file to a plurality of user terminals;
receiving, from each of the plurality of user terminals, data indicating a guessed geographical position with which the user of that user terminal associates said media file;
updating the assigned geographical position for the media file based on the guessed geographical positions received from each of the plurality of user terminals; and
determining whether said media file is indicative of a geographical position by;
either comparing the assigned geographical position with each guessed geographical position, or comparing the guessed geographical positions with one another; and
calculating a verification rating for the media file based on said comparison, the determination as to whether or not the media file is indicative of a geographical position being based on said verification rating, wherein the verification rating value is recalculated each time data indicating a guessed geographical position is received, the verification rating being recalculated as follows;

Abstract
The invention relates to a system for verifying geographical descriptiveness of a media file, such as a picture. The system comprises storage means adapted to store a media file, communication means adapted to send said media file to a plurality of user terminals, and to receive, from the user terminals, data indicating a guessed geographical position with which the user of each user terminal associates the media file. The system also comprises calculation means adapted to determine whether the media file is indicative of a geographical position based on the guessed geographical positions received from the plurality of user terminal.

15. A system for verifying geographical descriptiveness of a media file, wherein the system comprises:
-
a storage medium configured to store a media file and data indicating an assigned geographical position of the media file; a communication circuit configured to send said media file to a plurality of user terminals, and to receive, from each of the plurality of user terminals, data indicating a guessed geographical position with which the user of that user terminal associates said media file; and a calculation circuit configured to update the assigned geographical position for the media file based on the guessed geographical positions received from each of the plurality of user terminals, determine whether said media file is indicative of a geographical position by either comparing the assigned geographical position with each guessed geographical position, or comparing the guessed geographical positions with one another, and by calculating a verification rating for the media file based on said comparison, the determination as to whether or not the media file is indicative of a geographical position being based on said verification rating, wherein the calculation circuit is configured to recalculate the verification rating value each time data indicating a guessed geographical position is received, and wherein the calculation circuit is configured to recalculate the verification rating as follows; - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A computer program product comprising a non-transitory computer readable medium storing computer readable code that, when executed by a processor in a system comprising a storage medium storing at least one media file and data indicating an assigned geographical position of the media file and a communication circuit through which said system can communicate with user terminals connected thereto, causes the system to verify geographical descriptiveness of the media file, the computer readable code causing the system to:
-
send said media file to a plurality of user terminals; receive, from each of the plurality of user terminals, data indicating a guessed geographical position with which the user of that user terminal associates said media file; update the assigned geographical position for the media file based on the guessed geographical positions received from each of the plurality of user terminals; and determine whether said media file is indicative of a geographical position by; either comparing the assigned geographical position with each guessed geographical position, or comparing the guessed geographical positions with one another, and calculating a verification rating for the media file based on said comparison, the determination as to whether or not the media file is indicative of a geographical position being based on said verification rating, wherein the verification rating value is recalculated each time data indicating a guessed geographical position is received, the verification rating being recalculated as follows;
