Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current email systems face significant security concerns, including virus attacks and spam, and lack effective tracking and compliance features, making them inadequate for secure communication and data protection, especially in corporate settings.
Innovation Solution
A secure email system that employs a server-based architecture 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 messaging, metadata management, and message control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional e-mail systems are used, then ease of operation is maintained, but security and reliability are compromised due to virus attacks and spam
Solution Approach 1:
The patent introduces a server-based intermediary system that sits between senders and recipients. The server receives emails, performs security scanning, and distributes cleaned copies to recipients. This mediator handles the security complexity centrally while keeping recipient operations simple - they just receive emails without needing to configure security settings or manage antivirus software locally.
Solution Approach 2:
The patent extracts the security scanning and virus detection functions from individual recipient systems and consolidates them on a centralized server. This removes the burden of security management from end users while maintaining comprehensive security checking. The server handles all security-related operations, leaving recipients with a simplified experience of just receiving and reading emails.
2Reliability
If multi-layered protection methods are added to stop spam and viruses, then security is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple security functions (virus scanning, spam filtering, content analysis) into a single centralized server system. Instead of having separate security layers on each client device, all protection mechanisms are combined in one location, reducing overall system complexity while maintaining comprehensive security coverage.
Solution Approach 2:
The centralized server acts as an intermediary that consolidates all security operations. By placing multiple protection layers in one intermediary system rather than distributing them across many client devices, the patent reduces the complexity burden on individual systems while maintaining robust multi-layered security.
3Reliability
If encryption methods like PKI are implemented, then security is improved, but ease of operation deteriorates due to manual key management requirements
Solution Approach 1:
The patent implements automatic key management where the server system handles encryption and decryption operations without requiring user intervention. Users simply send and receive emails; the server automatically manages cryptographic keys, performs encryption of sensitive content, and handles decryption for authorized recipients. This eliminates the need for users to manually generate, exchange, or manage cryptographic key pairs.
Solution Approach 2:
The server acts as an intermediary that manages all cryptographic operations. Instead of users directly handling complex encryption and key management, the server intermediary automatically performs these functions in the background, transparently securing email content while keeping user operations simple.
4Reliability
If tracking capabilities are added to e-mail systems, then reliability and compliance are improved, but device complexity increases
Solution Approach 1:
The server acts as an intermediary that automatically tracks all email transactions including delivery status, reading status, forwarding, and printing. By centralizing tracking functions on the server rather than implementing them in client applications, the patent achieves comprehensive message tracking while keeping user devices simple and unchanged.
Solution Approach 2:
The system implements automatic feedback mechanisms where the server continuously monitors and records email transaction status. Tracking information is automatically generated and maintained without user input, providing reliable compliance data while requiring no additional complexity from user systems. Users simply receive emails; the server handles all tracking and reporting automatically.

AI summary
An e-mail system is disclosed that overcomes many deficiencies of, but is backward compatible with, existing e-mail systems. An exemplary method for communicating e-mail messages includes receiving an e-mail message from a sender addressed to a recipient, receiving a request for access to the e-mail message from an e-mail client associated with the recipient, and providing the e-mail client with access to the e-mail message. The method further includes receiving a navigation notification indicating a navigation away from the e-mail message followed by a navigation return to the e-mail message, and in response, withholding access to the e-mail message by the e-mail client, and providing the e-mail client with a message placeholder.
