InkDNA – Fingerprinted Downloads

Screenshots

Developer docs: https://inkdnafingerprint.com/docs 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.
