PRIVACY PRESERVING USER PERSONALIZATION USING NOISY RANKING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240346178 titled 'PRIVACY PRESERVING USER PERSONALIZATION USING NOISY RANKING

The system described in the patent application tracks website usage while protecting user privacy by aggregating data across multiple users and websites. This aggregated data preserves individual user privacy by allowing access to information relevant to a specific user without revealing what was collected from that user.

• Aggregates website usage data of multiple users across multiple websites
• Preserves individual user privacy by aggregating data in a way that hides the source of the information
• Uses trusted execution environment computing hardware to aggregate user-specific data while maintaining privacy
• Applies differential privacy techniques to ensure that aggregated information does not reveal specific details about a user's website usage history
• Enables scenarios that would typically rely on third-party cookies while maintaining user privacy

Potential Applications: - Online advertising targeting - Website analytics - User behavior analysis

Problems Solved: - Protecting user privacy while tracking website usage - Preserving individual user data in aggregated information

Benefits: - Enhanced user privacy protection - More accurate website usage tracking - Compliance with privacy regulations

Commercial Applications: Title: Enhanced User Privacy System for Website Usage Tracking This technology can be used in online advertising, website analytics companies, and any platform that tracks user behavior online.

Questions about the technology: 1. How does this system ensure user privacy while tracking website usage? 2. What are the potential implications of using this technology in online advertising targeting?

Frequently Updated Research: Stay updated on advancements in differential privacy techniques and trusted execution environment computing hardware to enhance the system's capabilities.

Original Abstract Submitted

disclosed is a system that tracks website usage without compromising user privacy. the system aggregates website usage data of multiple users across multiple websites. website usage data is aggregated in a way that preserves each individual user's privacy. specifically, information relevant to a particular user may be obtained from the aggregated information without exposing what was actually collected from that user. in some configurations, user-specific website usage data is aggregated using trusted execution environment computing hardware. this ensures that privacy is preserved while user-specific data is transferred to and processed by the system. the trusted execution environment applies differential privacy techniques to ensure that use of the aggregated information does not reveal actual information about a user's website usage history. in this way, privacy is maintained while still enabling many of the scenarios that would otherwise rely on third-party cookies.
