Abstract

A test person is compared to a reference person by comparing detailed information regarding the configuration, capabilities and usage of computers—such as installed hardware devices, makes and models and firmware versions of such hardware devices, installed software, versions of installed software, and usage logs—used by the respective individuals. In effect, each person'"'"'s computer is considered a proxy for the person herself, representing countless purchasing, maintenance, pastime choices in the configuration and use of a thoroughly complex personal and professional tool.

Claims

1. A method for determining the similarity of a test person to a reference person, the method comprising:

receiving an accumulation of single reversible hashes that represent multiple items of system information pertaining to a test computer device that has been used by the test person, wherein each single reversible hash includes multiple reversible hashes of data elements representing characteristics of the test computer device, each characteristics selected from a group consisting essentially of;

a hardware component, a hardware configuration, a software component, a software configuration, and a usage of the test computer device;

parsing each single reversible hash into its constituent multiple reversible hashes;

parsing the constituent multiple reversible hashes;

initializing a correlation score representing a measure of correlation between the test computer device and a reference computer device associated with the reference person;

identifying, for each of the constituent multiple reversible hashes, one or more corresponding items of system information of the reference computer device, wherein the corresponding items each correspond to at least one of the data elements representing characteristics of the test computer device;

for each of the corresponding items;

comparing the corresponding item to the at least one of the data element to determine a degree of similarity between the corresponding item and the at least one data element; and

adjusting a correlation score according to the degree of similarity; and

determining a measure of similarity between the test person and the reference person according to the adjusted correlation score.

2. The method of claim 1 wherein identifying comprises:

determining that each of one or more predetermined device profile correlation rules applies to both (i) at least one of the data elements representing characteristics of the test computer device and (ii) at least one of the items of system information of a reference computer device.

3. The method of claim 2 wherein each of one or more predetermined device profile correlation rules specifies the degree of similarity between data elements and items of system information to which the predetermined device profile correlation rule applies.

4. The method of claim 2 wherein each of the one or more predetermined device profile correlation rules defines one or more data elements to which the predetermined device profile correlation rule applies by specifying a type of data element, a test value of a data element, and a test operation for comparison of the test value.

5. A computer system comprising:

at least one processor;

a computer readable medium that is operatively coupled to the processor;

network access circuitry that is operatively coupled to the processor; and

comparison logic (i) that executes at least in part in the processor from the computer readable medium and (ii) that, when executed, causes the computer system to determine the similarity of a test person to a reference person by at least;

sending logic to a test computer device that, when executed by the test computer device, generates one or more data elements representing characteristics of the test computer device;

receiving system information pertaining to the test computer device that has been used by the test person, wherein the system information includes the one or more data elements representing characteristics of the test computer device selected from a group consisting essentially of;

a hardware component, a hardware configuration, a software component, a software configuration, and a usage of the test computer device;

identifying one or more corresponding items of system information of a reference computer device used by the reference person, wherein the corresponding items each correspond to at least one of the data elements representing characteristics of the test computer device;

for each of the corresponding items;

comparing the corresponding item to the at least one data element to determine a degree of similarity between the corresponding item and the at least one data element; and

adjusting a correlation score according to the degree of similarity; and

determining a measure of similarity between the test person and the reference person according to the adjusted correlation score.
