Self-Erasing Proxy Network for Low-Latency Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for maintaining data privacy in communication systems, such as TOR and Vuvuzela, introduce long latency and limitations in request frequency due to the need for complex routing and cover traffic, which compromise efficiency and user experience.
Innovation Solution
A proxy network with self-erasing processing elements, including ingress and egress containers, that temporarily store and forward data requests between servers, erasing all involved processing elements after completing their task to reduce latency and enhance security without requiring additional cover traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If TOR or Vuvuzela networks are used to protect data privacy through complex routing and cover traffic, then data privacy is improved, but communication latency increases significantly
Solution Approach 1:
The patent implements self-erasing processing elements (SEPEs) that automatically delete themselves and all associated data after completing a single request-response cycle. These disposable computational entities provide strong privacy protection without requiring persistent infrastructure, thereby reducing latency compared to traditional multi-hop routing systems like TOR.
Solution Approach 2:
The patent extracts the privacy-protection function from complex multi-server routing architectures and concentrates it into single-hop SEPEs. By removing unnecessary intermediate servers and cover traffic mechanisms, the system achieves privacy protection with minimal latency overhead.
2Reliability
If TOR or Vuvuzela networks implement complex routing protocols with cover traffic, then traffic analysis resistance is improved, but request frequency is limited due to long latency
Solution Approach 1:
Self-erasing processing elements enable high request frequency by completing each request in a single hop and then automatically deleting themselves. This disposable approach eliminates the need to wait for long-lived servers to become available again, allowing continuous rapid request initiation.
Solution Approach 2:
The patent removes cover traffic requirements by extracting the privacy function into SEPEs that inherently protect through their self-destruct nature. This eliminates the latency overhead associated with generating and processing cover traffic, enabling immediate request initiation.
3Productivity
If processing elements persist in the network to handle multiple requests, then system efficiency is improved, but security is compromised due to potential threats like remote access Trojans and zombie armies
Solution Approach 1:
The patent resolves this contradiction by making processing elements disposable rather than persistent. Each SEPE handles exactly one request and then self-destructs, eliminating the security risks of persistent systems while maintaining efficiency through automated resource management. The system spawns new SEPEs for each request, ensuring fresh, uncompromised processing entities.
Solution Approach 2:
The patent implements automatic discarding of processing elements after use, with the understanding that computational resources are recovered and reused for new SEPEs. This cycle of creation, use, and destruction maintains both security and efficiency without requiring persistent vulnerable infrastructure.

AI summary
Systems and methods are provided for maintaining data privacy in a communication system. The method includes: providing a proxy network which creates a plurality of ingress processing elements and a plurality of egress processing elements, wherein the ingress processing elements and the egress processing elements each include at least a private processing unit and a private memory area; receiving a request at a selected ingress processing element from a first server; routing the request from the selected ingress processing element to a selected egress processing element; forwarding the request from the selected egress processing element to a second server; and erasing both the selected ingress processing element and the selected egress processing element.
