Abstract
Systems and methods are provided to facilitate distribution and synchronization of digital objects between a plurality of computing devices. In an embodiment, a master file catalog is maintained at a central server. As updates are made to digital object(s) on devices associated with the central server, file catalogs are forwarded to the master catalog which is updated accordingly. The master catalog can then be reviewed to facilitate file sharing in a peer-to-peer manner between the devices. In another embodiment, one-way hash pairings are created when a digital object is created/modified. Received hash pairings can be analyzed to facilitate determination of whether two extants of a digital object are the same or different. Utilizing one-way hash pairings enable sensitive information regarding a digital object to remain secure, and sensitive information (and digital objects) is only shared between authenticated devices.
