Encrypted Email Relay With Reply Redaction and Audit Proof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing email systems lack the ability to ensure secure and private transmission of messages, as well as the means to verify and record such transmission, which is necessary for compliance with data privacy regulations like HIPAA and GDPR, and to prevent insecure replies that expose sensitive information.
Innovation Solution
A system that provides end-to-end encryption with automated record-keeping, allowing senders to ensure secure transmission and recipients to verify the encryption status, while also offering redaction options for replies to maintain privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If standard email transmission protocols (SMTP, ESMTP, HTTP, HTTPS) are used, then ease of operation is improved, but security and privacy of transmitted information deteriorates
Solution Approach 1:
The patent introduces an intermediary encryption layer between the sender and recipient. The encryption service provider acts as a mediator that receives the plaintext message, encrypts it, and delivers the ciphertext to the recipient. This intermediary process maintains ease of use for users while ensuring security through automated encryption without requiring users to manually configure security settings or understand cryptographic protocols.
Solution Approach 2:
The system implements self-service encryption where the encryption and decryption processes are automatically performed by the system without requiring user intervention. The sender's email client automatically encrypts messages before transmission, and the recipient's client automatically decrypts them upon receipt. This self-service mechanism maintains ease of operation while ensuring consistent security application.
2Reliability
If encryption methods are implemented to protect sensitive information, then security is improved, but ease of operation deteriorates due to user complexity
Solution Approach 1:
The encryption system operates as a self-service mechanism where the email client automatically handles encryption and decryption without requiring user configuration or intervention. Users simply compose and send emails as usual, and the system transparently applies encryption protocols, maintaining ease of use while ensuring security.
Solution Approach 2:
The patent implements a universal encryption solution that works across different email clients and platforms. The encryption service provides a standardized interface that can be integrated into various email systems (Outlook, Gmail, Apple Mail, etc.), allowing the same encryption methodology to be applied universally without requiring users to learn different procedures for different systems.
3Reliability
If secure transmission methods are used, then privacy compliance is improved, but device complexity increases due to additional encryption infrastructure
Solution Approach 1:
The patent introduces an intermediary encryption service that handles the complexity of encryption infrastructure externally. Rather than requiring each email server or client to implement and maintain complex encryption systems, the intermediary service centralizes the cryptographic operations, reducing device complexity at the user end while ensuring compliance through standardized encryption protocols.
Solution Approach 2:
The encryption system performs self-service by automatically managing key generation, exchange, and management without requiring manual configuration or complex infrastructure setup. The system autonomously handles the cryptographic lifecycle, reducing the burden on system administrators and users while maintaining compliance with privacy regulations.
4Reliability
If encryption and record-keeping systems are implemented, then ability to demonstrate compliance is improved, but device complexity and operational overhead increase
Solution Approach 1:
The system implements self-service compliance reporting by automatically generating and maintaining audit trails of encrypted transmissions. The encryption service autonomously records encryption events, key usage, and transmission metadata, and can automatically produce compliance reports for regulatory review, eliminating the need for manual compliance tracking and reducing operational overhead.
Solution Approach 2:
The patent incorporates feedback mechanisms where the encryption system automatically provides confirmation to users and regulators that encryption was successfully applied. The system generates automated audit logs and compliance certificates that feed back into the organizational compliance framework, providing verifiable evidence of secure transmission without requiring manual verification processes.

AI summary
A system for processing a received email having redacted content, and/or where the message content has been reformatted, encrypted and recorded as encrypted, and where the message header is parsed to determine the security level of the message, storing the security level in a database, and forwarding a secure and/or redacted message to an intended recipient.
