Global Document Type Identifier (GDTI)

The Global Document Type Identifier can be used by companies to identify documents, including the class or type of each document.

In cases where companies require identification of individual documents, an optional alphanumeric serial number can be included in the GDTI.

The term “document” is applied broadly to cover any official or private paper that infers a right (a proof of ownership) or obligation (notification or call for military service) upon the bearer, or a diploma or certificate.

Such documents typically require recording of the appropriate information contained on the document. Examples of the kind of documents that could benefit from a GDTI are physical documents such as certificates, invoices, driving licenses, and electronic documents such as digital images, EDI messages.

The GDTI can be encoded in a bar code or printed directly on the document. Companies can use the GDTI as a method of identification and registration of documents and related events.

They can also use the GDTI for information retrieval, document tracking, and electronic archiving.

One specific application is the prevention of fraud and document falsification; for example, assigning a GDTI to each diploma or certificate that is then linked to a central registry.
