Key selling point in one sentence: Package PDFs into local HTML, store on USB drives or NAS – each opening requires lightning-fast authorization from the server, ensuring confidentiality and revocability.
| Traditional Approach | Pain Points | Offline Version Solution |
|---|---|---|
| Full Upload to Cloud Drives | Data remains with third parties, high compliance pressure | Files remain only in your hands or internal network |
| Pure Local Encryption | Out of control once sent, cannot be revoked | Each opening requires verification, can be locked at any time |
| Professional DRM Platform | Complex deployment, high costs | One-click HTML generation, affordable for individuals |
PDFs are encapsulated into a single HTML, easily copied to USB drives / private NAS.
Background-level handshake upon opening: verifies reading code, remaining uses, expiration date. Disconnection → direct refusal to launch.
Read Code: View only; Encode: Replace files, add uses. Retain a "regret button" while sharing files.
Each verification request records IP, time, clear at a glance in the background – who has viewed, when it ended, one-click export to CSV.
| Industry / Occasion | Specific Use |
|---|---|
| Hardware Manufacturing Delivery | Package blueprints into HTML to accompany equipment on-site; customer's computer has no internet? Bring your own portable Wi-Fi router to emit a one-time hotspot for verification. |
| Legal and Auditing | Lawyers submit due diligence materials, limit to 5 uses with reading code; after the audit, "terminate authorization" with one click in the background using encoding. |
| Exhibition / Training | Distribute product white papers via USB drive, automatically cache pages after initial verification, can still browse offline for 24 hours after leaving the exhibition hall. |
| University Research | Internally exchange draft papers, files remain on the school's server; external collaborators can scan the QR code for temporary verification to view. |
Upload PDF → Complete encapsulation within 30 seconds.
Number of views, expiration date, whether to lock IP / region.
Get Project_X_Spec.html + simultaneously generate access/edit codes & QR code.
Tips: Write the version number clearly in the file name to facilitate the other party's browser tab display and reduce misreading.
Non-Printable / Disable Copying: Browser-level disabling of print menus, right-click, and shortcuts.
Dynamic Watermark: Automatically overlays date + IP when opened, screenshots can also trace the source.
HTTPS Verification Channel: Authorization handshake uses an encrypted channel to prevent man-in-the-middle tampering.
One-Time Reading Mode: Deduct uses upon opening, invalidates when the window is closed, preventing screenshots and background streaming.
| Item | Description |
|---|---|
| Cost | Personal & small team version is permanently free; ultra-high concurrency can be upgraded to a paid plan (billed by verification count, almost 1% of the cost of traditional DRM). |
| Deployment | No server or local software required; the browser is the reader. |
| Update | If there are new features, re-upload the original PDF to get the new version of HTML; the old package is not affected. |
