Secure Email Verification Service Using Hash-Based Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The proliferation of unsolicited bulk email (SPAM) continues to pose a significant challenge, consuming network resources and potentially carrying malware, with existing solutions often failing to distinguish between legitimate and illegitimate messages effectively.
Innovation Solution
A secure email verification service that generates and verifies unique user identifiers through hashing, ensuring the integrity and authenticity of email messages by embedding a hash value within the message, which is compared upon receipt to verify its authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If key exchange methods are used to establish trust relationships, then sender and recipient security is improved, but system complexity increases due to key management requirements
Solution Approach 1:
The patent introduces a verification service as an intermediary that generates and manages verification values on behalf of senders. Instead of direct key exchange between sender and recipient, the verification service acts as a trusted mediator that both parties can rely on, eliminating the complexity of direct key management while maintaining security.
Solution Approach 2:
The verification service automatically generates verification values and manages the verification process without requiring manual key exchange or management by users. The system performs self-service by autonomously creating, distributing, and validating verification values, reducing the burden on end users.
2Difficulty of detecting and measuring
If algorithm-based SPAM identification is used, then SPAM detection capability is improved, but legitimate messages are incorrectly blocked reducing reliability
Solution Approach 1:
The verification value is generated and attached to the email message before it is sent. This preliminary action ensures that the verification mechanism is in place before the message reaches the recipient, allowing for accurate verification without interfering with legitimate message delivery. The verification service prepares everything in advance, avoiding last-minute algorithmic decisions that could block legitimate messages.
3Loss of energy
If message limiting approaches are used to reduce SPAM, then network resource consumption is improved, but legitimate email communications are impacted reducing productivity
Solution Approach 1:
Instead of applying blanket message limits to all users, the patent applies verification selectively to individual messages based on their verification status. Each message is evaluated locally based on whether it contains a valid verification value, allowing legitimate communications to proceed without artificial limits while still protecting against SPAM.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach effectively reduces the impact of SPAM by ensuring only authentic messages are delivered, minimizing the risk of malware and resource consumption, while eliminating the need for complex algorithms and digital signing processes.
Implementation Method 1
The secure email verification service can generate a hash of the user identifier, the global time indicator, the message-specific data, and/or other data to obtain a hash value
Data Source
AI summary
Concepts and technologies are disclosed herein for providing and using a secure email verification service. A processor can receive verification data and identify a user identifier associated with a sender identifier included in the verification data. The processor can generate a hash value of the user identifier, a global time indicator, and message-specific data; and send the hash value to the sender device. The processor can receive a verification package that comprises the hash value and a recipient device version of the verification data and generate a new hash value of the user identifier and the recipient device version of the verification data. The processor can compare the new hash value to the hash value to determine if the email message should be verified.
