Uniform User Identifier Generation via Access Set Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining unique user identifiers across multiple websites are insecure due to reliance on third-party central servers, making user data vulnerable to security intrusions and complicating data exchange between websites.
Innovation Solution
A system and process that generates a uniform user identifier by analyzing access requests from visiting users, using combinations of header field elements and network address identifiers to determine the lowest information loss rate, allowing websites to identify and exchange user data without relying on third-party servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a third-party central server is used to generate unique user identifiers, then user identification across websites is achieved, but user data security deteriorates due to vulnerability to security intrusions
Solution Approach 1:
The patent extracts the user identification function from the third-party central server and implements it locally at each website. Each website independently generates and manages its own user identifiers using cryptographic algorithms, eliminating the need to send user data to external servers and thereby removing the security vulnerability associated with third-party involvement.
Solution Approach 2:
The patent introduces a cryptographic hash algorithm as an intermediary mechanism that enables secure user identification without requiring direct communication with a central server. The hash algorithm processes user data locally to generate identifiers that can be exchanged between websites without exposing sensitive information, acting as a secure mediator that eliminates the need for trusted third parties.
2Adaptability or versatility
If user data is exchanged among websites to provide personalized products, then user experience is improved, but data security risk increases due to potential security intrusions
Solution Approach 1:
The patent creates a cryptographic copy of user identification data that can be exchanged between websites without transferring the actual sensitive user information. Each website generates a hashed version of the user identifier that preserves the ability to recognize and personalize for the user while eliminating the security risk of exposing raw user data during exchanges.
Solution Approach 2:
The patent transforms user identification data from its original sensitive form into a cryptographic hash representation. This parameter change converts the data into a form that maintains its identification functionality while removing the security vulnerability, allowing websites to exchange and use the data for personalization without risking exposure of sensitive information.
