Dual-Authentication Document Delivery via Separate Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods of electronic document transmission lack security, as emails with links to sensitive documents are easily compromised during relay through multiple servers and are often stored by these servers, leading to unintended access.
Innovation Solution
A dual-authentication system using two different communication paths, where a sender transmits information through a network, requiring recipients to access two separate messages with distinct authentication codes to access the document, ensuring secure delivery and avoiding third-party storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional email transmission is used to send document links, then ease of operation is improved, but security is worsened due to relay through multiple servers and storage by third parties
Solution Approach 1:
The authentication process is segmented into multiple independent steps: first authentication via email message, second authentication via separate authorization code. This segmentation ensures that even if one channel is compromised, the document remains protected, resolving the security issue while maintaining operational simplicity through automated multi-factor authentication.
Solution Approach 2:
A server acts as an intermediary between the sender and recipient, managing the secure transmission process. The server sends the document link through email and separately provides authorization codes through messaging services, preventing direct exposure of sensitive information and eliminating third-party storage risks while maintaining ease of use.
2Reliability
If multiple authentication systems are implemented, then security is improved, but device complexity is worsened
Solution Approach 1:
The system uses universal communication channels (email and messaging services) that users already have access to, rather than requiring specialized authentication hardware or software. This multi-functional approach leverages existing infrastructure to provide enhanced security without increasing device complexity or requiring users to learn new systems.
3Ease of operation
If documents are relayed through multiple servers, then ease of operation is improved, but loss of information is worsened due to unauthorized access and archiving
Solution Approach 1:
The system discards traditional email-based document sharing by not attaching or linking directly to documents in emails. Instead, it provides only authorization codes that temporarily grant access. The actual document remains with the sender, and access is recovered only through proper authentication, preventing unauthorized archiving while maintaining transmission ease.
Data Source
AI summary
The secure electronic document delivery system enables a sender to identify file information and recipient information to be sent to a recipient. The system utilizes an authentication system requiring access to two different authentication messages, both access to electronic mail and access to a message sent to the recipient's phone. The two authentication messages are transmitted via two different communication paths thus requiring the recipient to access two different types of communications. Without accessing both messages, the recipient cannot access the document identified by the sender.
