Email Privacy Enforcement via Tracking Code Removal

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional email systems fail to effectively protect user privacy from tracking codes embedded in email messages, allowing senders to monitor recipient interactions without consent.

Innovation Solution

An email system equipped with privacy enforcement circuitry that analyzes incoming and outgoing emails for tracking codes, modifies or removes them, and caches external content to prevent tracking, ensuring user privacy without requiring client-side modifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If tracking codes are embedded in email messages to monitor recipient interactions, then sender ability to track engagement is improved, but recipient privacy is compromised

Engineering Contradiction:

Improvetracking capabilityVSAvoidprivacy violation

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The system extracts tracking codes from email messages by scanning the message content and identifying tracking code suspects based on characteristics such as transparency, size, and URL patterns. The extracted tracking codes are then removed or replaced with dummy tracking codes that do not provide actual tracking capability, thereby eliminating the privacy violation while maintaining the email's functional integrity

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The email system acts as an intermediary between the sender and recipient by intercepting emails, analyzing their content for tracking codes, and modifying them before delivery. This intermediary function allows the system to protect recipient privacy by removing tracking codes without requiring any changes to the recipient's email client or software

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If privacy enforcement circuitry scans and modifies emails to remove tracking codes, then recipient privacy is protected, but email processing complexity increases

Engineering Contradiction:

Improveprivacy protectionVSAvoidprocessing complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The system performs preliminary scanning of email messages during the email reception process, before the emails are delivered to recipients. By identifying and removing tracking codes at this early stage, the system prevents tracking violations without requiring complex real-time analysis or client-side processing, thereby protecting privacy while maintaining reasonable processing complexity

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system replaces manual or client-side tracking prevention mechanisms with a centralized server-side solution. Instead of requiring recipients to install and configure privacy protection software on their devices, the email system itself performs the tracking code removal, simplifying the overall system architecture while effective protecting privacy

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Object-affected harmful factors

If tracking codes are removed or replaced before email delivery, then recipient privacy is enhanced, but sender tracking capability is reduced

Engineering Contradiction:

Improveprivacy securityVSAvoidtracking data

Core Design Contradiction:

Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The system converts potentially harmful tracking codes into beneficial privacy protection mechanisms by replacing them with dummy tracking codes. These dummy codes appear to be functional tracking codes but actually provide no tracking capability, thereby eliminating the harmful effect while maintaining the appearance of normal email functionality

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

A message handling system comprising connection handler circuitry, message parser circuitry, message modification circuitry, message processing circuitry, and content caching circuitry, wherein the message parser circuitry is operable to extract header(s) and/or content of a received message. The message modification circuitry is operable to generate a modified message by inserting, into the message, an HTML tag comprising a first unique uniform resource locator (URL). The connection handler circuitry is operable to send the modified message to a device that handles messages for the recipient. The message processing circuitry is operable to analyze the one or more headers and/or content. The message processing circuitry is operable to determine which image of a plurality of images to serve in response to a request containing the first unique URL, wherein the determination is based on the analysis of the one or more headers and/or content. The content caching circuitry is operable to serve the determined image.
