Abstract
A method for linking data using permanent tokens is disclosed. The tokens may be used to link data pertaining to a consumer, a business, an address, an occupancy, or a household. The tokens are created in a central repository, which maintains an identification class for each entity. The identification class contains all available information concerning the entity. The tokens may be applied to a data storage system to allow real-time construction of a total customer view. The tokens may also be used to link the data storage system to a repository, such that the total customer view contains all available information concerning the customer. The total customer view may be used to formulate a response to customer input, such as a purchase or access to an Internet web page maintained by the data owner. By matching tokens instead of names and addresses, potential ambiguities and erroneous duplicates are eliminated. Data updates may be performed incrementally, and may be pushed from the repository to the data owner as new information is received.
