The challenge
Your valuable creations and private materials—from designs and webcomics to private photos and educational materials—can be easily copied and shared by recipients. On top of that, even AI can steal your materials. This directly impacts your profits, your ownership rights, and your privacy. While you need to prevent this unauthorized sharing, forcing recipients to install complex Enterprise Digital Rights Management (EDRM) software is difficult for everyone.
The Digital Coating (Dico) difference
Digital Coating makes strong security simple. Traditional security is often hard to use, and solutions that are easy aren't very strong. We’ve solved that by providing top-level protection that’s designed for the general public, making it both powerful and incredibly easy to use.
Advanced defense for your digital content
Secure your creations and private files
Protected without extra software
01. Zero-client security "Seamless business security without any installation." Securely view documents directly in any web browser without the need for dedicated software. Remove technical friction and build trust with partners through a hassle-free viewing experience.
02. Remote content control "Stay in control, even after your files are sent." Instantly revoke access permissions in real-time, even for files already delivered. Prevent unauthorized sharing by automatically locking access to the first browser used. Set expiration dates for files to self-destruct or lock automatically after a specific period.
03. Advanced anti-leakage technology "Ironclad protection against recipient misuse and AI bots." Blocks all screen capture and automated AI scraping attempts. Even if files are downloaded, they remain securely encrypted and inaccessible without authorized permission. To prevent external capture attempts, our specialized filters make photography extremely difficult, while dynamic watermarks serve as a powerful deterrent against unauthorized leaks.
04. Granular tracking "Identify the digital footprints of your data." Track exactly how many times your files were opened with detailed access logs. Maintain full transparency by monitoring real-time access history, including timestamps and connection details.

Dico vs General Image/PDF DRMs
Feature
General image/PDF DRM solutions
Digital Coating (Dico)
Viewer installation req
Required. Usually needs a dedicated viewer program to be installed.
Not required. Can be viewed directly in a standard web browser (Chrome, Safari, Edge, etc.).
DRM operation method
Encryption and permissions (editing, printing, copying restrictions) are embedded directly within the file itself. The viewer interprets the file and enforces security policies.
The file exists in an encrypted form on the server. DICO's in-browser viewer decrypts it in real-time within the browser's memory and renders it as pixels on the screen. Instead of direct file download, a secure viewing link controls the access environment.
File distribution method
The encrypted file itself is downloaded/distributed to the user.
The file is not directly downloaded. Users receive a secure 'viewing link' and access it via a web browser.
