Message Recall System Using Cryptographic Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing message recall technologies face challenges in verifying the authenticity of the sender and ensuring the reliability and security of the recall process, especially when operating across administrative domains, leading to potential premature or malicious recalls.
Innovation Solution
The implementation of a messaging system that uses unique recall, secret, and tracking identifiers (R, S, T) generated through cryptographic hash functions to authenticate and authorize recall requests, ensuring that only authorized users can initiate recall operations, and employing a hold time to increase the likelihood of successful recalls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional message recall methods are used, then the recall operation can be initiated by the sender, but the authenticity of the sender cannot be verified reliably
Solution Approach 1:
The system performs preliminary authentication by embedding cryptographic identifiers (recall identifier, secret identifier, tracking identifier) in the message before transmission. These identifiers are generated in advance and attached to the message, enabling verification of the sender's authenticity when recall is requested, without requiring complex real-time verification systems.
Solution Approach 2:
The patent introduces cryptographic identifiers as intermediaries between the sender and the recall verification system. The recall identifier, secret identifier, and tracking identifier act as mediators that carry authentication information through the message lifecycle, allowing the receiving system to verify sender authenticity without direct complex interaction with the original sender.
2Reliability
If message recall is implemented without proper verification, then the recall operation is simple to perform, but the recall may be premature or malicious
Solution Approach 1:
The system embeds cryptographic verification identifiers (recall identifier, secret identifier, tracking identifier) in the message before transmission. When recall is requested, these pre-existing identifiers enable automatic verification of the requester's authority, ensuring secure recall operations without requiring complex real-time authentication procedures from the user.
Solution Approach 2:
The message itself carries all necessary authentication information through its cryptographic identifiers. The system uses these embedded identifiers to automatically verify the authenticity of recall requests without requiring external verification mechanisms, making the secure recall process both reliable and operationally simple.
3Reliability
If cryptographic identifiers are embedded in messages, then sender verification and authorized recall are enabled, but the system complexity increases
Solution Approach 1:
The authentication system is segmented into three distinct cryptographic identifiers: recall identifier, secret identifier, and tracking identifier. Each identifier serves a specific function in the verification process, dividing the complex authentication mechanism into manageable, specialized components that can be independently generated, transmitted, and verified.
Solution Approach 2:
The cryptographic identifier system serves multiple functions simultaneously: the recall identifier enables message identification and recall initiation, the secret identifier provides authentication verification, and the tracking identifier monitors message delivery status. This multi-functionality reduces the need for separate verification systems while maintaining high security standards.

AI summary
The present disclosure provides a method and system for enabling the recall of messages. As an example, the method comprises receiving a message, where the message is created by a sender and configured to be sent to a recipient. The method further comprises identifying a first identifier for the message. The first identifier is configured to verify the sender of the message and enable a recall operation for the message. The recall operation results in the recall of the message, and the recall of the message involves cancelling the transmission of the message to the recipient or deleting the message.
