Referral URL Tracking for Encrypted Content Sharing Chains

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing communication platforms, particularly personal messaging services, hinder effective tracking of content sharing due to end-to-end encryption and private channels, making it difficult to monitor sharing activities and referral chains.

Innovation Solution

A tracking server system that dynamically tracks content sharing by generating unique referral identifiers and URLs, storing referral chains in a data structure, and using requester identifiers to track and analyze sharing patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If end-to-end encryption is implemented in personal messaging services, then user privacy and security are improved, but the ability to track content sharing and referral chains deteriorates

Engineering Contradiction:

Improveuser privacy and securityVSAvoidtracking data

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The system segments the tracking function from the encrypted messaging service by introducing a separate tracking server that operates independently. The tracking server receives referral URLs with embedded tracking identifiers, allowing it to monitor content sharing without decrypting actual messages. This segmentation enables simultaneous maintenance of encryption for privacy and tracking for analytics.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The tracking server acts as an intermediary between users and the content sharing network. It receives and processes referral URLs containing tracking identifiers, building referral chains without accessing the encrypted content of messages. This intermediary approach allows tracking functionality while preserving end-to-end encryption of actual communications.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If private channels are implemented in personal messaging services, then user confidentiality is improved, but the accessibility of sharing data to third parties deteriorates

Engineering Contradiction:

Improveuser confidentialityVSAvoiddata accessibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system separates confidential messaging channels from public tracking channels. Private messaging services maintain their encrypted, private channels for actual communication, while the tracking server operates on public channels to collect and analyze referral URL data. This segmentation allows both confidentiality and data accessibility to coexist.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The tracking server serves as a public intermediary that collects sharing data without accessing private channels. It processes referral URLs that are shared publicly or semi-publicly, building referral chain information while leaving the actual private messaging channels inaccessible to third parties. This resolves the contradiction by providing data accessibility through the intermediary without compromising channel privacy.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Loss of information

If referral tracking is implemented in encrypted messaging networks, then content sharing visibility is improved, but the complexity of the tracking system deteriorates

Engineering Contradiction:

Improvecontent sharing visibilityVSAvoidtracking system complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The system extracts only the essential tracking elements (referral URLs with embedded identifiers) from the complex encrypted messaging environment. By focusing solely on tracking these specific URL elements rather than attempting to monitor all messaging activities, the system achieves content sharing visibility while keeping the tracking implementation relatively simple and targeted.

Inventive Principle:

Principle #2Taking out (Extraction)

4Measurement precision

If dynamic referral identifier generation is implemented, then tracking precision is improved, but the computational overhead deteriorates

Engineering Contradiction:

Improvetracking precisionVSAvoidcomputational overhead

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary actions by pre-generating and embedding unique referral identifiers in URLs before content is shared. This allows tracking to occur passively when URLs are accessed, rather than requiring complex real-time analysis of encrypted messages. The computational work is done in advance during URL generation, reducing ongoing computational overhead while maintaining high tracking precision.

AI summary

A tracking server may receive, from a requester, a content request for accessing a content element on a content server. The content request includes a request Uniform Resource Locator (“URL”) with at least a content identifier specifying the requested content element on the content server, and a request referral identifier. If the content identifier does not refer to a content element provided on the content server, an error response is sent. If the content identifier refers to a content element provided on the content server, a new and unique referral identifier associated with the content request is generated. Further, a new and unique referral URL for the content request is generated as a response URL comprising the received content identifier and the newly generated unique referral identifier. The requested content element is then served to the requester under the response URL.
