Adds an invisible, per-buyer fingerprint to each download—no DRM.
Highlights
* DRM-free: Buyers get normal PDFs/images.
* Per-buyer fingerprints: Embedded at download time.
* Screenshot-resilient: Survives common transforms (marking PDFs; detecting PDFs & images).
* Privacy-aware: Marking happens server-side on your store. The plugin calls the InkDNA API from the server and writes a temporary marked copy locally.
* Works with Woo downloadable products (no catalog changes).
This plugin uses a fixed InkDNA API base endpoint: https://ashtonx24-inkdna.hf.space
External services
This plugin connects to your InkDNA API from the server.
Service host
– https://ashtonx24-inkdna.hf.space (API base)
What is sent (server API)
– For local product files: POST /mark with the PDF file as multipart/form-data.
– For remote product URLs: POST /mark/url with JSON body { "url": "<source pdf url>" }.
– Headers on both requests: X-Order-Id (the WooCommerce order ID) and X-API-Key (set in Settings InkDNA).
When it is sent
– Only when a buyer initiates a download. The store server calls the InkDNA API, receives a fingerprinted PDF, stores it temporarily under wp-content/uploads/inkdna-fingerprinted-downloads/, and serves that local file to the buyer.
What returns
– A fingerprinted (marked) PDF, unique per order.

설치
- Upload the ZIP and Activate the plugin.
- Go to Settings InkDNA and set:
- API Key (the key assigned/created for your shop)
- API Base (default https://ashtonx24-inkdna.hf.space) and your API Key. The plugin performs server-side marking on download.
- In WooCommerce, create a Downloadable product and attach a PDF.
- Place a test order and download. Each download is uniquely fingerprinted via the InkDNA loader + API.
FAQ
-
Do I need an InkDNA account?
-
Yes — you or your tenant must have an InkDNA tenant and API Key. The plugin requires that API Key to enable stamping.
-
What file types are supported?
-
Marking: PDFs
Detecting: PDFs and images (PNG/JPEG) — handled outside WordPress (see “How do I verify a leak?”). -
File size limits?
-
Server defaults typically allow ~25–100 MB (configurable). WordPress/PHP upload limits may also apply.
-
Is this DRM?
-
No. Files remain standard PDFs/images. We embed a robust, invisible fingerprint so you can attribute leaks even after edits/screenshots.
-
Does this store my files or customer data?
-
The plugin stores a temporary, per-order fingerprinted PDF under wp-content/uploads/inkdna-fingerprinted-downloads/ in order to serve the download. No API keys are exposed to the browser.
-
How do I verify a leak?
-
Use the Verify page at your InkDNA endpoint (e.g.,
/verify.html) or the hosted verification tool documented at https://inkdnafingerprint.com/docs. Upload the suspect file and review the signed evidence JSON. -
Caching/CDN?
-
Do not CDN-cache the API responses; each PDF is unique per buyer. Re-downloads use the local marked copy cached by the plugin in
/wp-content/uploads/inkdna-fingerprinted-downloads/. -
Do I have to send an Order ID?
-
Yes. The fingerprint is bound to the order identifier. If omitted at marking time, later verification can still estimate but won’t be provable to a specific purchase.
