Method and system for compiling a multi-source database of composite investor-specific data records with no disclosure of investor identity

摘要

A system and method are disclosed for compiling a database of investor-related data by gathering and linking customer-specific data records from multiple unaffiliated financial institutions, where such data records are coded in such a manner that the database compiler is enabled to link, across data providers and/or time periods, data records that pertain to the same investor without being provided any information that reveals the identity of any investor.

1. A method of compiling a computerized database of anonymized investor-specific financial data received from a plurality of data providers, the method comprising:
inputting, using a computer and from each data provider, a set of data comprising:
investor-specific financial data maintained by the data provider pertaining to a plurality of investors, andwith respect to each investor, a surrogate investor code that is associated with the investor-specific financial data pertaining to that investor,
wherein the surrogate investor code corresponds to a single value of an investor identifier maintained by the data provider in association with that investor-specific financial data,wherein the surrogate investor codes inputted from all data providers correspond to values of the same investor identifier,wherein each distinct value of the investor identifier represents a distinct investor,wherein the set of data from each data provider does not disclose the values of the investor identifier, andwherein the surrogate investor code inputted from a data provider that corresponds to a particular value of the investor identifier is different from the surrogate investor codes inputted from other data providers that correspond to that value of the investor identifier; determining, using a computer and based upon a data-matching mechanism, which surrogate investor codes correspond to the same value of the investor identifier,
wherein the data-matching mechanism does not disclose the values of the investor identifier; and linking in the database, using a computer, investor-specific financial data inputted in association with surrogate investor codes that correspond to the same value of the investor identifier.
