Intermediary Email Security System with Automated Key Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current email systems face significant security concerns, including virus attacks and spam, and lack effective tracking and archiving capabilities, making them unsuitable for secure communication and compliance with regulations such as Sarbanes-Oxley and Health Insurance Portability and Accountability Act requirements.
Innovation Solution
A secure email system that uses a server-based approach with encryption and a client plug-in to intercept and manage emails, allowing secure storage, tracking, and retrieval of messages, while enabling features like private and public messaging, metadata management, and customizable encryption methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional email systems are used for communication, then ease of operation is maintained, but security against virus attacks and spam is compromised
Solution Approach 1:
The patent introduces an intermediary email security system that sits between the sender and recipient. The system intercepts emails at the server level, performs security scanning, and delivers cleaned emails to recipients. This intermediary layer maintains ease of operation for users while providing comprehensive security protection against viruses and spam.
Solution Approach 2:
The patent implements preliminary security scanning and filtering of emails before they reach the recipient's system. By performing virus scanning, spam filtering, and security checks in advance during the email delivery process, the system prevents malicious content from entering user systems while maintaining normal email operation for legitimate users.
2Reliability
If multi-layered protection methods are added to email systems, then security against spam and viruses is improved, but system complexity increases
Solution Approach 1:
The patent consolidates multiple security functions (virus scanning, spam filtering, content analysis) into a single intermediary email security system. Rather than adding separate complex protection layers at various points in the email infrastructure, the intermediary system provides comprehensive multi-layered protection through one centralized component, reducing overall system complexity while maintaining security effectiveness.
3Reliability
If email tracking and archiving capabilities are implemented, then compliance with regulations is improved, but loss of information through incomplete tracking is reduced
Solution Approach 1:
The patent implements comprehensive email tracking that provides feedback on the complete lifecycle of email messages. The system tracks emails from sending through delivery to archiving, maintaining detailed records of each stage. This feedback mechanism ensures complete tracking information is captured, enabling reliable compliance with retention and archiving requirements while preventing information loss about email provenance and delivery status.
4Reliability
If encryption is applied to email messages, then security is improved, but ease of operation deteriorates due to key management requirements
Solution Approach 1:
The patent implements automated key management where the email security system automatically generates, distributes, and manages encryption keys without requiring manual user intervention. The system handles key generation, secure distribution to authorized parties, key rotation, and expiration automatically. This self-service approach maintains strong encryption security while eliminating the operational burden of manual key management for users.

AI summary
An e-mail system is disclosed that overcomes many deficiencies of, but is backward compatible with, existing e-mail systems. Embodiments of the system may include various features, including but not limited to: (1) secure transfer of e-mail messages, without the need for users to replace existing e-mail clients or to change e-mail addresses; (2) tracking of all actions performed in connection with an e-mail transmission; (3) the ability for a recipient to view information about an e-mail message, optionally including information about how other addressees have responded to it, before deciding whether to retrieve the e-mail message; (4) the aggregation of entire e-mail conversations into a single threaded view; (5) the ability to include both private and public messages in a single e-mail communication; (6) sender control over downstream actions performed in connection with an e-mail message; (7) flexible control over cryptographic methods used to encrypt emails messages for storage.
