Filed:

Appl. No.:

09/167393

Andrew V. Sutherland - Concord MA

Assignee:

The Escher Group, Ltd. - Cambridge MA

International Classification:

G07B 1700

US Classification:

705 62, 705408, 705410

Abstract:

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.

International Classification:

US Classification:

709203, 709220, 709226, 711162

Abstract:

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.

US Classification:

705 11, 705406, 705407, 705409, 705401, 705404, 705411, 705330

Abstract:

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.

International Classification:

G06F007/00

US Classification:

709/001000, 709/100000

Abstract:

A method and apparatus for linking data objects and physical objects of various kinds for a user is described. A particularly useful application of such linkage associates a user identifier with one or more physical addresses to which the user wishes to direct the delivery of the physical objects. Different types of objects may be directed to the same or different addresses, and the association can be changed partly or wholly by the user when desired.

Abstract:

A system and method of processing instructions may comprise an application processing domain (APD) and a metadata processing domain (MTD). The APD may comprise an application processor executing instructions and providing related information to the MTD. The MTD may comprise a tag processing unit (TPU) having a cache of policy-based rules enforced by the MTD. The TPU may determine, based on policies being enforced and metadata tags and operands associated with the instructions, that the instructions are allowed to execute (i.e., are valid). The TPU may write, if the instructions are valid, the metadata tags to a queue. The queue may (i) receive operation output information from the application processing domain, (ii) receive, from the TPU, the metadata tags, (iii) output, responsive to receiving the metadata tags, resulting information indicative of the operation output information and the metadata tags; and (iv) permit the resulting information to be written to memory.
