A server and method are provided for determining a matching score related to users of wearable camera systems. In one implementation, a server determines a matching score related to users of wearable camera systems. Each wearable camera system is configured to capture images from an environment of a corresponding user and produce image data from the captured images. At least one processing device associated with the server may be programmed to receive image data from the wearable camera systems. The processing device may further determine a value of a matching score related to at least two users of the wearable camera systems. The value of the matching score may be based on the image data received from the wearable camera systems. The value of the matching score may indicate a level of exposure of the two users to similar visual details in their environments.
