Abstract: A computing device may provide a credential related to a service. Responsive to a validation of the credential, an identification of the service may be added to a contact listing associated with the computing device. Thereafter, a user of the computing device may select the service from the contact listing in order to upload a content object to the service. Similarly, the user of the computing device may select one or more peer devices from the contact listing. Responsive to the peer device selections, the content object may be transmitted to the one or more peer devices.

Abstract: A method for handling meta data of media objects, comprising creating a media object at a mobile electronic device, obtaining at least one rule defining modifications for positional data relating to at least one geographical area, determining positional data relating to the current geographical position of said mobile electronic device, applying said at least one rule to said positional data to derive positional meta data if said positional data relate to said at least one geographical area, deriving positional meta data from said determined positional data if said determined positional data do not relate to said at least one geographical area, and associating said positional meta data with said media object. An electronic device capable of performing the method is also provided.
