FAQ - Protect Your Documents with Tamper-Proof Digital Signatures and QR Codes

Qryptal Secure QR Code technology is a unique solution that enables physical or electronic documents to be tamper-proof and instantly verifiable by any third party. It generates a highly secure digital signature with embedded data placed on the document as a QR Code, which can be easily verified by scanning the code with a smartphone app or a web validation mechanism. This serverless solution is built on PKI and has a key size equivalent to 3072 bits, making it highly secure. It can be used offline and with both electronic and physical documents while also protecting the privacy and confidentiality of the customer and institution. Two main types of Qryptal Secure QR Codes are Primary Data Codes (PDCs) and Extended Data Codes (EDCs), the former can work offline while the latter can be revoked or chained with a new code and can carry any amount of data. Qryptal Secure QR Code technology is easy to use, with a simple workflow for integrating with the Qryptal Generator API and installing the Document Validator App.

Q: What is Qryptal Secure QR Code technology?

A: Qryptal Secure QR code technology makes physical or electronic documents tamper-proof and instantly verifiable by any third party using a unique server-less architecture. It generates a highly secure digital signature with embedded data placed on the document as a QR Code, which can be easily verified by scanning the code with a smartphone app.

Q: What are the benefits of using Qryptal Secure QR Code technology?

A: Some benefits include server-less architecture for easy scalability and virtually maintenance-free operation, high security based on PKI with a key size equivalent to 3072 bits, offline verification that does not require network connectivity, ability to work with both electronic and physical documents, and protection of privacy and confidentiality.

Q: How do I generate and use Qryptal Secure QR Codes?

A: To generate Qryptal Secure QR Codes, you can integrate with the Qryptal Generator API. The codes can then be easily added to your documents to enable validation. To validate the codes, end-users can install the Document Validator App on their mobile phone. This can be done via web validation as well by visiting the issuer’s verification domain (for example : verify.demobank.in) and following the prompts to either scan the code using the browser camera or upload an image or PDF file containing the code. There is also an option to download and install the app on this page.

Q: What are Primary Data Codes and Extended Data Codes in Qryptal Secure QR Codes?

A: Primary Data Codes (PDCs) are self-contained codes that encapsulate all the information within the code, with a recommended capacity of around 2,000 characters. Extended Data Codes (EDCs) can also contain encrypted attachments, such as images and PDF files, which are stored as encrypted blobs in an object store such as Amazon s3 or Azure cloud storage. Their decryption key and fingerprints are stored within the QR code to prevent tampering. EDC QR codes can be revoked or chained with a new code.

Q: How can I learn more about Qryptal Secure QR Code technology?

A: The best way to understand this technology is to sign up for a free trial account on www.qryptal.com . You can also contact Qryptal (email : info@qryptal.com ) for more information.

Q: How does the Qryptal Secure QR Code solution work?

A: The Qryptal Secure QR Code solution generates a highly secure digital signature with embedded data placed on the document as a QR Code. This code can be easily verified by scanning it with the Document Validator App on a smartphone. The organization’s private key digitally signs the secure QR code, and the mobile app and web validation mechanism use the organization’s public key to validate the digital signature. The entire code is also explicitly compressed to create the smallest possible QR Code size.

Q: Is the Qryptal Secure QR Code solution secure?

A: Yes, the Qryptal Secure QR Code solution is highly secure. It is based on PKI (Public Key Infrastructure) with a key size equivalent to 3072 bits, which is much more secure than typical internet banking. In addition, the entire code is explicitly compressed with Qryptal’s proprietary algorithm to create the smallest possible QR Code size.

Q: Can the Qryptal Secure QR Code solution be used offline?

A: Yes, the Qryptal Secure QR Code solution (PDC codes) can be used offline since it is self-contained and does not require any network connectivity to validate the information. It can be used anytime and anywhere, including in secure air-gapped environments.

Q: Can the Qryptal Secure QR Code solution be used with electronic and physical documents?

A: Yes, the Qryptal Secure QR Code solution can be used with electronic and physical documents. It is designed to work with both types of documents, and the secure QR Code can be generated digitally and then placed on both the physical and electronic versions of the document as needed. Both the printed copy and the electronic format of the original document will carry the same level of security and can be easily verified.

Q: Does the Qryptal Secure QR Code solution protect privacy and confidentiality?

A: Yes, the Qryptal Secure QR Code solution helps to safeguard and protect the privacy and confidentiality of both the customer and the institution in a logical and uncomplicated manner.
