Private Domain Email Routing for Spam Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The openness of the Internet makes email addresses public, leading to issues with spam, viruses, and malware, as existing encryption solutions primarily focus on protecting email content rather than addresses, leaving them vulnerable to exploitation.
Innovation Solution
Implementing private domain addresses that are routable within a private domain, using encryption techniques such as RSA and PGP to ensure that both email content and addresses remain private, creating a secure communication environment similar to a gated community.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encryption is used to protect email content, then message privacy is improved, but email addresses remain public and vulnerable to spam and viruses
Solution Approach 1:
The patent segments the email address into two parts: a public portion for routing and a private portion for actual delivery. The private email address is divided into a public identifier and a private component that is only revealed to authorized recipients, separating the routing function from the delivery function to prevent spam while maintaining privacy.
Solution Approach 2:
The patent introduces a private domain controller as an intermediary between the public internet and private email delivery. This controller manages the translation between public and private address components, acting as a mediator that enables secure delivery without exposing private address information to the public internet.
2Reliability
If a pull email system is used with encrypted connections, then security is improved, but user convenience deteriorates as users must log in to receive email
Solution Approach 1:
The patent implements self-service by allowing the email system to automatically translate and route messages using the private domain controller without requiring user authentication for each message reception. The system serves itself by managing the encryption and routing automatically, eliminating the need for users to manually log in while maintaining security.
3Productivity
If standard email addresses are made public for push email delivery, then delivery reliability is improved, but address security deteriorates making users vulnerable to spoofing and phishing
Solution Approach 1:
The patent applies local quality by making different portions of the email address have different properties: the public portion is visible and routable on the internet, while the private portion is hidden and only accessible within the private domain. This creates a localized privacy boundary where address information is exposed only where necessary for routing, protecting users from spoofing while maintaining delivery capability.

AI summary
Methods and apparatuses for private electronic information exchange are described herein. In one embodiment, when electronic information is received to be delivered to a recipient, the electronic information is transmitted over an electronic network with a private routing address. The private routing address is routable within a private domain, which is a subset of the electronic network. Other methods and apparatuses are also described.
