A system and method for linking data objects and physical objects of various kinds to an identified user is described. The system provides to the identified user information relating to the delivery status of mail pieces directed to or sent by the user, and the user then tracks and traces the mail pieces. The system further provides to the identified user information relating to continued sessions through which the user provides to a postal service system information relating to mailing labels and postage.

A peer-to-peer storage system includes a storage coordinator that centrally manages distributed storage resources in accordance with system policies administered through a central administrative console. The storage resources, or 'nodes,' are otherwise unused portions of storage media, e.g., hard disks, that are included in the devices such as personal computers, workstations, laptops, file servers, and so forth, that are connected to a corporate computer network, and are thus otherwise available only individually to the respective devices. The storage coordinator assigns the nodes to various 'replication groups' and allocates the storage resources on each of the nodes in a given group to maintaining dynamically replicated versions of the group files. The storage nodes in a given group perform dynamic file replication and synchronization operations by communicating directly, that is, peer-to-peer, using a message-based protocol. The storage coordinator also manages distributed searches of file content on the network by selecting one node from each group to search through the associated group files. The selected nodes report the search results back to the storage coordinator, which organizes the results and provides them to the user. Thereafter, in response to a request for various files by the user, the storage coordinator instructs the nodes that are near neighbors of the user to provide the requested files. The storage coordinator thus ensures that the amount of the network bandwidth consumed by the search operation is minimized.

A system is disclosed for distributing postage over a public network in a manner that is secure in the case of third party interception, indicia for which can be efficiently printed by a postal customer on items to be mailed, and that facilitates authentication of the printed indicia. When the postal customer purchases postage from the postal service, the postal service provides information which the postal customer uses to generate pseudo-random numbers associated with the respective units of postage. When the postal customer prints an indicium for a respective unit, it appends the associated pseudo-random number, which the postal service uses to authenticate the indicium. The pseudo-random numbers are generated using a methodology by which the postal customer can generate pseudo-random numbers for units which have been purchased, but not for units which have not yet been purchased. Each indicium represents an amount of information which can be printed using a one-dimensional barcode, instead of two-dimensional barcodes required in other systems.
