Abstract
Abstract A method and system for client/server communications in which stored user information controls revealed and delivered information. A client system is Communicatively coupled to a server through an intermediate system, which acts as a persona module. User information about a user on the client system is stored on the client system. Information about advertising information is stored on the server. The intermediate system receives information about user information from the client system and information about advertising information from the server. The intermediate system acts as a user's agent to filter out irrelevant advertisement material. The intermediate system can also function to customize the advertisements received by the client system from the server, but not returning information about the user's interest or preferences to the server. A user's privacy may be further protected if the information returned to a server is at least partially untruthful.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
143 words
A method of communications between a client system and a server communicatively coupled to the client system through an intermediate system, comprising the steps of: receiving information based on user information from the client system, at the intermediate system; receiving information based on advertising information from the server, at the intermediate system; comparing the information based on user information with the information based on advertising information, at the intermediate system; selecting relevant information by the intermediate system based upon the comparison; and transmitting the relevant information from the intermediate system to the client system, wherein the step of transmitting information based on user information comprises the steps of: generating a permutation function at the client system; generating a first result of the permutation function applied to a user interest vector, at the client system; and transmitting the first result to the intermediate system.
Claim 2
Independent Claim
143 words
A method of communications between a client system and a server communicatively coupled to the client system through an intermediate system, comprising the steps of: receiving information based on user information from the client system, at the intermediate system; receiving information based on advertising information from the server, at the intermediate system; comparing the information based on user information with the information based on advertising information, at the intermediate system; selecting relevant information by the intermediate system based upon the comparison; and transmitting the relevant information from the intermediate system to the client system, wherein the step of transmitting information based on user information comprises the steps of: generating a permutation function at the client system; generating a first result of the permutation function applied to a user interest vector, at the client system; and transmitting the first result to the intermediate system.
Claim 3
Dependent Claim
65 words
The method of claim 1 , wherein the step of transmitting information based on advertising information comprises the steps of: receiving the permutation function from the client system at the server; generating a second result of the permutation function applied to an advertising information signature vector relating to advertising information, at the server; transmitting the second result and the advertising information to the intermediate system.
Claim 4
Dependent Claim
28 words
The method of claim 2 , wherein the comparing step comprises the step of: generating a measure of the correlation of the first result and the second result.
Claim 5
Dependent Claim
40 words
The method of claim 3 , wherein the step of generating a measure of the correlation of the first result and the second result comprises the step of: generating an inner product of the first result and the second result.
Claim 6
Independent Claim
139 words
A system for facilitating communications between a coupled client system and a coupled server, comprising: a first receiver receiving information based on user information from the client system; a second receiver receiving information based on advertising information from the server; a selection device selecting relevant information based on a comparison of the information based on user information with the information based on advertising information; a transmitter transmitting the selected relevant information to the client system; a third receiver receiving a first result of a permutation function applied to a user interest vector from the client system; a fourth receiver receiving a second result of the permutation function applied to an advertising information signature vector relating to advertising information, from the server; and a device for generating a measure of the correlation of the first result and the second result.
Claim 7
Independent Claim
139 words
A system for facilitating communications between a coupled client system and a coupled server, comprising: a first receiver receiving information based on user information from the client system; a second receiver receiving information based on advertising information from the server; a selection device selecting relevant information based on a comparison of the information based on user information with the information based on advertising information; a transmitter transmitting the selected relevant information to the client system; a third receiver receiving a first result of a permutation function applied to a user interest vector from the client system; a fourth receiver receiving a second result of the permutation function applied to an advertising information signature vector relating to advertising information, from the server; and a device for generating a measure of the correlation of the first result and the second result.
Claim 8
Dependent Claim
