Everything QR – Here are 6 questions to ask on Secure QR code

Why all QR codes are not the same

Today’s document security is way different and more advanced than options available a decade ago. Today, we live in a generation where robust & easy to deploy solutions are available with highly compressed digitally signed QR codes that can be validated on demand in a decentralized manner. These secure quick response codes have transformed the way businesses use QR codes for document security.

1. Created by authorised systems only

A secure QR is very different from a regular QR as it is digitally signed by the private key of the issuer and can only be created by their authorized systems/personnel. Hence a secure QR code cannot be tampered with or modified in an unauthorized manner. A regular QR, on the other hand, does not have any security and can be created and modified by anyone, thereby making this a wrong choice for most document security needs.

2. URL-less QR is Phishing proof

A regular QR code typically carries a URL and is highly vulnerable to phishing attacks. That’s why it is usually not recommended to have a URL inside the QR code. However, a good secure QR code can also support this option where the use case requires this capability.

3. Time tested Private-Key, Public-Key based security (PKI)

Another advantage of a secure QR code is that since a private key digitally signs the QR, it can only be read by a specific app/ QR reader/ or a validation mechanism with the corresponding public key. On the other hand, a regular QR is scanned by generic QR readers, which may capture sensitive personal data, which makes it a security and privacy risk.

4. Proprietary Compaction Algorithms

It is a good idea to use a proprietary algorithm that generates compact QR codes with high levels of security and information integrity compared to regular QR codes. Such a mechanism helps to generate a smaller and more secure QR code for a given amount of information. Qryptal for example has such a proprietary algorithm

5. Blockchain like Encryption

A secure QR technology has, in a way, combined QR Codes with blockchain-like encryption and digital signing to enable secure, centralized “truth” generation with decentralized validation in a scalable, cost-effective manner which has been commercially proven in multiple use cases.

6. Quick and efficient deployment

Though the QR code itself is based on open standards, those with extensive experience (e.g Qryptal) have built on it to provide security along with ease of use. Standards based architecture and running it as micro service, enables clients to do successful deployments exceptionally rapidly - in a matter of days.

Qryptal’s QR code solution has all the above features. With its technical expertise, Qryptal can help you implement this efficiently and successfully and keep pace with any changes to specs or requirements that may evolve with time. We are also able to deploy the solution at scale to take care of millions of codes that may be needed for different use cases.
