1. A method of compiling an electronic database of entity-specific information maintained by a plurality of unaffiliated institutions, comprising the steps of:
- providing each institution with a computer-based device that provides surrogate entity codes, wherein each surrogate entity code (i) corresponds to a unique value of entity identification information maintained by such institution, and (ii) is generated in such manner that no entity identification information can be derived from such surrogate entity code, and wherein the computer-based devices provide, with respect to any specific value of such entity identification information, surrogate entity codes that are different for each institution but all convertible to a common surrogate entity code;
receiving from each institution a set of data records, each of which contains information that pertains to a particular entity and is associated with a surrogate entity code, but which is otherwise free of entity identification information;
installing in the database the data records provided by the plurality of institutions; and
linking the data records at the entity-specific level by converting the different surrogate entity codes from the different institutions into common surrogate entity codes and then, with respect to each common surrogate entity code, logically associating all data records with which such common surrogate entity code is associated.

Abstract
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.
