US 7,647,504 B2 · Method and system for efficiently retrieving secured data by securely pre-processing provided access information

Abstract

A method and system for efficiently retrieving secured data by securely pre-processing provided access information, provides data store security based on a single piece of access information, which is generally public, such as the proper name of a business or individual that is used to retrieve mailing address information. The access information is hashed for access to a secured data store and efficient access and low data storage for permutations of input access information are provided by verifying the presence of an entry for the hashed access information in a look-up table. If an entry is found, the data store is accessed using the hashed access information, but if an entry is not found, another look-up table corresponding to another information type may be tried or the input access information permuted and retried.

Claims18

Dependent claims

A method, implemented by a computing system, for retrieving secured data from a secured data store, comprising:

receiving access information from an inquiry source, said received access information being part of a data store inquiry;
extracting a type-independent portion of said received access information from said received access information;
hashing said type-independent portion of said received access information to produce a hashed result;
determining whether or not an entry corresponding to said hashed result is present in a look-up table;
in response to determining that said entry corresponding to said hashed result is present in said look-up table, retrieving said secured data corresponding to said received access information from said secured data store using said type-independent portion of said received access information and a secure retrieval algorithm associated with said secured data store;
and
transmitting information from said retrieved secured data to said inquiry source.

4 more elements

A computer system comprising a processor for executing program instructions and a memory coupled to said processor for storing program instructions and data, wherein said program instructions comprise program instructions for:

receiving access information, said received access information being part of a data store inquiry;
extracting a type-independent portion of said received access information from said received access information;
hashing said type-independent portion of said received access information to produce a hashed result;
determining whether or not an entry corresponding to said hashed result is present in a look-up table;
and
in response to determining that said entry corresponding to said hashed result is present in said look-up table, retrieving secured data corresponding to said received access information from a secured data store using said type-independent portion of said received access information and a secure retrieval algorithm associated with said secured data;
and
transmitting information from said retrieved secured data in response to said data store inquiry.

5 more elements

A computer program product comprising a tangible media encoding program instructions for execution within a general-purpose computer system, wherein said program instructions comprise program instructions for:

receiving access information, said received access information being part of a data store inquiry;
extracting a type-independent portion of said received access information from said received access information;
hashing said type-independent portion of said received access information to produce a hashed result;
determining whether or not an entry corresponding to said hashed result is present in a look-up table;
in response to determining that said entry corresponding to said hashed result is present in said look-up table, retrieving secured data corresponding to said received access information from a secured data store using said type-independent portion of said received access information and a secure retrieval algorithm associated with said secured data store;
and
transmitting information from said retrieved secured data in response to said data store inquiry.
