The Google Drive Risk Report by Metomic reveals that 40.2% of the documents stored in the cloud storage without any security protection contain sensitive data. This calls for the prioritization of security without removing convenience when sharing files.
New approaches, like using QR code for PDF file sharing, are employed by organizations nowadays as they directly store the documents and can be protected with passwords.
An even more secure PDF QR code does not just simplify access and manage who gets in, but also control for how long and under what conditions. This all boils down to the kind of PDF QR code generator applied.
To help you find the most secure one out of the thousands, let’s explore the most reliable QR code generator for PDF you can count on for document-sharing.
What makes a file QR code truly secure?
File QR codes are convenient for sharing documents. But like other methods, QR codes will not be secure if you use a random PDF QR code generator with no security compliance at all.
Even when QR codes are not inherently unsafe, malicious actors are able to use them for unauthorized data access and hacking of a software or system. This can happen if you’re not careful enough when creating or scanning one.
This is why the generator matters a lot. They not only keep your data and documents safe but also protect the information of the people you share it with.
Secure QR code generators typically have features such as:
Two-factor Authentication: Requires two different kinds of identification to access your account and data.
End-to-end Encryption: Third parties, even the software, cannot access your data when transferred from one device or system to another.
Secure Servers: Employs robust security protocols and best practices to ensure the safe transmission of communications and data across the Internet.
Security Certifications: Certified to have data privacy and security standards in place.
Password Protection: Ensures only those with the password can access the file.
Expiry Dates: Gives you control over how far your codes go after distribution.
Download Limits: Allows you to restrict downloads after your file has reached the intended audience.
Tools that offer dynamic QR codes are considered more secure as they allow the editing of links in cases of breach or unauthorized access.
