Multi-Channel Verification Code Segmentation for Secure Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user identity verification methods lack strong security protection and are vulnerable to document leaks, as verification codes sent over single channels can be easily intercepted by unauthorized parties.
Innovation Solution
A method involving sending and receiving information over different transmission channels, where recovered security data is generated and used to authenticate users, ensuring that only authorized users can access confidential information by decrypting protected documents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If verification code is sent over a single transmission channel, then the verification process is simple and fast, but the security protection is weak and vulnerable to interception
Solution Approach 1:
The verification code is divided into multiple segments and sent through different transmission channels (e.g., SMS, email, push notification). Each channel carries a portion of the complete verification code, so that intercepting one channel does not compromise the entire verification process. This segmentation approach directly addresses the security weakness while maintaining manageable system complexity.
Solution Approach 2:
The system introduces an intermediary mechanism that collects verification code segments from multiple channels, validates them, and reconstructs the complete verification code. This intermediary layer enhances security by ensuring all segments are properly verified before granting access, while abstracting the complexity from the user experience.
2Reliability
If multiple transmission channels are used for verification, then security protection is enhanced, but the verification process becomes more complex
Solution Approach 1:
The system merges multiple verification code segments received from different transmission channels into a single complete verification code. This combining process happens automatically in the background, allowing the user to interact with a single unified verification flow despite multiple channels being involved, thus maintaining ease of operation while enhancing security.
Solution Approach 2:
The system automatically manages the collection, validation, and combination of verification code segments from multiple channels without requiring manual user intervention. The user simply receives the verification prompt and inputs the code, while the system handles the complex multi-channel coordination in the background, preserving operational simplicity.
3Reliability
If verification code is sent through one channel, then the process is quick and straightforward, but it is vulnerable to document leaks
Solution Approach 1:
The system performs preliminary actions by pre-configuring multiple transmission channels and establishing the segmentation scheme before the verification process begins. This preparation ensures that when verification is needed, the multi-channel process can execute efficiently without significant time penalty, while providing enhanced document security through the distributed verification approach.
Data Source
AI summary
Verification of a data recipient is disclosed, including: sending, to a server, a request for requested information, wherein the request includes identifying information associated with a user; receiving, from the server, at least two pieces of information over different transmission channels; sending, to the server, recovered security data that is generated based at least in part on the at least two pieces of information, wherein the server is configured to determine whether the recovered security data matches stored security data; receiving, from the server, protected requested information associated with the request; and using the recovered security data to recover unprotected requested information based at least in part on the protected requested information.
