At VeryPDF, we understand how critical it is to protect your intellectual property, especially when it comes to distributing eBooks and other valuable digital content. Our DRM Protector solution is designed to give you control, security, and flexibility—all while providing a user-friendly experience for your customers.
In this blog post, we’ll address some of the most common questions from our users about DRM protection for eBooks, covering topics like anti-screenshot features, encryption standards, subscription plans, and device restrictions.
1️⃣ Anti-Screenshot Protection: How It Works and Customization Options
Question:
The program closes quickly with a black background—this is useful for preventing screen captures, but it closes too fast. Can this time be extended? Also, is it possible to display a dynamic watermark with customer details (like IP address, email, and name) to discourage unauthorized photography?
Our Response:
The black-screen feature is intentionally designed to prevent screen captures. If we extend the black-screen duration, it may reduce its effectiveness in preventing screenshots. However, we understand the need for a balance between security and user experience. If you prefer, we can add an option to disable the black screen entirely—this will make reading more convenient for your customers.
As for watermarks, yes, we can embed dynamic, non-removable watermarks that display information like the customer’s IP address, email, and name, both on the screen and permanently within the PDF. This is an excellent way to deter photography with a phone or camera.
Once you subscribe, we can add this feature for you at no additional cost.
2️⃣ Encryption: 128-bit RC4 vs. 256-bit AES
Question:
Can I switch from 128-bit RC4 encryption to 256-bit AES? And can my developer set this up independently for our e-store?
Our Response:
Absolutely! You can enable 256-bit AES encryption by selecting the appropriate option on our online platform:
Go to https://drm.verypdf.com/online/ → Encryption → Enable PDF Encryption → Compatibility → Select “Acrobat 9.0 and later (256-bit AES).”
However, it’s important to note that 256-bit AES encryption is integrated into our DRM Protector system and cannot be separated for independent use. Could you clarify how you intend to use this functionality in your e-store? We’re happy to assist.
3️⃣ Subscription Plans: Monthly vs. Yearly
Question:
I’m considering starting with the monthly plan to test the software. If it works well, I’d like to pay for a full year. Do you provide a formal agreement or contract for annual use?
Our Response:
To streamline the purchasing process, we do not require a formal agreement or contract. You can simply subscribe directly from our website.
We recommend starting with our Starter plan at $99.95 per month. Once you’re satisfied, you can cancel the monthly plan and subscribe to the yearly plan. If you prefer, you’re also welcome to begin with an annual subscription from the start.
4️⃣ Integrating DRM Protection with Your eStore
Question:
I’d like to ensure every eBook sold through my e-store is automatically protected. I also need a way to send protected, permanent copies to libraries or organizations, and have control over device limits (e.g., max two devices per customer). Is this possible?
Our Response:
Yes! Here’s how we address your needs:
✅ Offline Access: Customers can download and read the protected eBook offline, not just online.
✅ Device Restrictions: Rather than relying on IP addresses (which can change when users travel), we lock the file to specific devices. For example, if you allow reading on two devices, the first two devices that open the PDF will be registered. The PDF will then be readable only on those two devices. This helps prevent sharing and unauthorized access.
✅ Auto-Destruction and Expiry: You can set a PDF to automatically expire and self-destruct after a set time period (e.g., 3, 6, or 12 months) or when tampering is detected.
✅ Manual Distribution Options: If you’d like to send protected copies (e.g., for libraries or promotional purposes), you can still manually generate and distribute them. The system supports both automated API workflows and manual workflows—the choice is yours.
✅ Dynamic Watermarks: We can embed watermarks that display the customer’s name, email, and other details directly on the document, deterring unauthorized sharing or photography.
5️⃣ Single-Page and Two-Page View Modes
Question:
Can my readers choose between single-page and two-page view modes, like in Adobe Reader?
Our Response:
Yes! We’re currently finalizing this feature in our Online PDF Viewer. Once it’s available, your protected eBooks will support both single-page and two-page view modes, offering your customers a more flexible reading experience.
This feature can be added to your subscription at no extra cost after purchase.
6️⃣ Clarifying API Functionality and Data Security
Question:
Does your API involve Artificial Intelligence? How can I be sure my content won’t be studied or copied by AI systems like ChatGPT?
Our Response:
No, our API is not an AI system. It is simply a tool for automating the PDF encryption and protection process—similar to a script that performs tasks automatically, instead of manually. Your content is not exposed to AI analysis, and we do not distribute or study your files.
7️⃣ Integration Guide for Your eStore Developer
Question:
Can you provide detailed instructions for my e-store developer to integrate your DRM solution, so that the system delivers protected copies automatically?
Our Response:
Absolutely. Your developer can find integration code samples and documentation on this page:
