Abstract: A network-based system is described for generating a digital data object mosaic. The system comprises: a data storage device for storing data objects; a network-accessible data server implementing a data object sharing platform comprising a sharing interface for presenting the data objects as visual representations; and a network connection for accessing the platform. The sharing interface comprises a digital mosaic for display in a user interface, the digital mosaic comprising a pre-selected background image and selectable tiles, at least some of which being associated with a data object, the association with a given selectable tile being indicated by a visual representation of an associated data object on the given selectable tile. The data object sharing platform accepts data objects from a given user in association with a specific selectable tile, and wherein subsequent selection of the specific selectable tile by a user provides access to the associated data object.
