Abstract: The information surrounding the manufacturing of a product is called a manufacturing context. The manufacturing context of a product provides details about the source and quality of raw material together with the detail of manufacturing and quality assurance throughout the manufacturing process. A product identifier is a unique identifier generated from a manufacturing context to uniquely identify one or more products manufactured under the same condition. Information about a retailer and its environment is called a retailer context. A retailer identifier is a unique identifier that identifies a retailer context. A product's authenticity context is comprised of the authenticity of a product and the authenticity of a retailer. The production identifier and the retailer identifier are made available to consumers at the point of sale so that the authenticity context can be determined.

Abstract: A virtual online document management system wherein an original document is broken down into logical pages before uploading into the document repository in a network environment. Each logical page is converted into a separate electronic image file. Each logical page is an addressable unit within the computer's storage. A virtual document consists of a sequence of pointers to the corresponding logical pages. These virtual documents can also be organized into virtual folders, again by the use of a sequence of pointers. The pointers to the logical pages that designate the virtual documents and the virtual folders are maintained in a computer software program practicing the disclosed method. The user operates on the logical pages with the program to create new virtual documents, retrieve the pages over the network, and to aggregate virtual documents to form virtual folders.
