SYSTEMS AND METHODS FOR IDENTIFYING AND CHARACTERIZING CLIENT DEVICES
First Claim
1. A method operable in one or more computers for determining information about a requesting client device, the one or more computers comprising circuitry forming one or more processors and a memory storing instructions to be executed by the one or more processors to perform the method, the method comprising:
- at a first computer of the one or more computers, performing an offline configuration process comprising;
creating an index that associates each of a plurality of tokens with one or more known client devices, and creating a lexicon file of tokens used in the index, wherein the index and the lexicon file are established prior to a request for content from a client device;
send the index and the lexicon file to a second computer of the one or more computers to be stored in the second computer;
at the second computer;
receiving the request for content from a client device, the request including information about the client device;
generating one or more tokens from the information in the request, based on the lexicon file;
identifying the client device as a particular one of the one or more known client devices, based on a comparison of the one or more tokens generated from the information in the request and the index;
wherein the identification step comprises;
(i) scoring the one or more known client devices, said scoring comprising;
matching a particular token from the information in the request to a token associated with a known client device in the index, wherein the occurrence of said match increases the score of the associated known client device;
(ii) identifying the client device as the highest-scoring known client device relative to others of the one or more known client devices.

Abstract
The teachings herein generally relate to client-server communications and the delivery of content over computer networks to clients, and provide improved methods, systems, and apparatus for identifying and/or characterizing client devices that are requesting content from a server. For example, based on information sent in a client device'"'"'s request for content, a web server modified in accordance with the teachings hereof can identify a set of characteristics associated with that client device. Such characteristics might include the model name of the client device, the screen dimensions of the client device, information about the particular operating system or browser name/version it is running, content formats it is capable of consuming, and so on. The web server can use this information to modify and customize its response for the given client device.

9. A system, comprising:
-
a first computer that has circuitry forming one or more processors and memory storing instructions to be executed by the one or more processors, the first computer operative upon execution of the instructions to perform an offline configuration process that comprises;
create an index that associates each of a plurality of tokens with one or more known client devices, and create a lexicon file of tokens used in the index, wherein the index and the lexicon file are established prior to a request for content from a client device;send the index and the lexicon file to a second computer; the second computer having circuitry forming one or more processors and memory storing instructions to be executed by the one or more processors, the second computer operative upon execution of the instructions to; (i) receive the request for content from a client device, the request including information about the client device; (ii) generate one or more tokens from the information in the request, based on the lexicon file; (iii) identify the client device as a particular one of the one or more known client devices, based on a comparison of the one or more tokens generated from the information in the request and the index. wherein the second computer identifies the client device as a particular one of the one or more known client devices by; (a) scoring the one or more known client devices, said scoring comprising matching a particular token from the information in the request to a token associated with a known client device in the index, wherein the occurrence of said match increases the score of the associated known client device; (b) identifying the client device as the highest-scoring known client device relative to others of the one or more known client devices. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
