Q넘버 (Qnumb3r)

[Introducing Qnumb3r]
Easy and safe two-channel authentication that allows authentication with just one touch without input


[main function]
Is an old certification a good one? As times change, certification must also change.
Easier and safer authentication without input, a new standard for 2-channel authentication!
Be the first to adopt Qnumber (Qnumb3r).
Advanced service competitiveness.

※ One-touch authentication
Unlike existing authentication methods that require multiple user actions, such as entering 6-digit numbers or text, authentication is done with just one touch, and since it is a touch method rather than input, incorrect input does not occur.

※ Question and answer method
The Q number can only be authenticated by a registered device, and since it is a question-and-answer method, reliable non-repudiation is possible. Additionally, it is safe from vulnerabilities that existing OTPs have, such as brute force attacks and interception.

※ Quantum-resistant cryptography (PQC) applied
Existing communication encryption methods (SSL/TLS, etc.) are known to have vulnerabilities, but Q Number is double-encrypted with QSafeE2E, which uses quantum-resistant encryption, to provide strong security.


[Required access rights]
- Notification: Required for authentication requests, identity verification, etc.
- Camera: Required for service application and backup.
※ If you do not agree, subscription to and use of the service will be restricted.
