Technology Overview: Secure Encrypted QR Code Generation

Overview

Qryptal Secure encrypted QR code technology is designed to make any document tamper-proof & instantly verifiable by any third party in a unique server-less architecture.

Secure Encrypted QR Code Generation | Electronic Authentication with App

The essential workflow for deploying Qryptal is to integrate with the Qryptal Generator API. The Qryptal Secure QR Code can be generated and seamlessly added to your documents to enable easy validation.
Sample Document with Qryptal Code

For validation, end-users can install the Document Validator App. You can try the following steps to install it on your mobile phone:

On your mobile, visit verify.demobank.in and follow one of these 3 methods :
(a) Click on the Use Camera button to scan the code directly using the browser camera or
(b) Upload Image/PDF file button to upload the image or PDF file containing the code or
(c) Install the app
After the app has been installed, scan the code above

The organisation’s private key digitally signs the secure QR code. The keys are generated initially as part of the setup. The mobile App and the web validation mechanism uses the organisation’s public key to validate the digital signature. Further, the entire code is explicitly compressed to create the smallest possible QR Code size. Contact us to learn more about this

REST API

The Qryptal Generator offers a REST API which can be called from almost any programming language/system.

You can sign up for free to try the API.

2 Types of Qryptal Secure QR Codes

Qryptal Secure QR Codes are of two types:

Primary Data Codes (PDC): These are self- contained codes which encapsulate all the information within the code itself. The recommended capacity of these codes is about 2,000 characters – large enough for a textual bank account statement like the sample given above.
Extended Data Codes (EDC): These codes can also contain attachments like images and PDF files. The attachments are encrypted and stored as BLOBS in object-store. The decryption key and their fingerprints are stored within the QR. This prevents any subsequent tampering of the codes.
Both the codes can be revoked or chained with a new code.
