# Find out where your images have been scraped > Source: > Published: 2026-08-26 22:45:55+00:00 Add as many images or works of art as you want. We generate a one-way fingerprint for each image, we do not retain or store your images. Lantern regularly scans newly-released AI training datasets. We fingerprint all images in these training datasets and match them against our database of your known works. If your work appears in an AI training dataset, we’ll send you an email with the work included and a link to the AI dataset, so you can submit a takedown notice. No, Lantern does not retain a copy of your art by default. Instead, we create a one-way fingerprint of your art. This identifier lets us search for your work in datasets, but cannot be used to reconstruct your art. You can optionally choose to allow Lantern to retain a small thumbnail of your work for a better dashboard experience. Lantern automatically scans the AI websites Hugging Face and ModelScope for new datasets. We also can manually add datasets to our index, if you are aware of a new dataset that is not on Hugging Face/ModelScope please send us a message and we can ingest it. Lantern uses the open-source [PDQ](https://github.com/facebook/ThreatExchange/tree/main/pdq) fingerprinting algorithm to generate fingerprints for your images (no images are sent to external servers), inspired by PhotoDNA and similar databases. We regularly ingest new publicly-available AI training datasets and notify you when your work appears. Lantern will provide you with a link to the source dataset. There, you can submit a takedown/DMCA notice. (TODO link to guide for how to submit notices on HF/MS). Lantern does not automatically submit takedowns for you, you must submit these yourself. While we aim to search most publicly-available AI training datasets, large companies like OpenAI, Google, and Anthropic use their own internal datasets rather than sets published on platforms such as Hugging Face. So Lantern is an attempt to notify you when your work appears in a publicly-available dataset, it is impossible to scan internal training datasets. Lantern is free to use, with generous watchlist limits to prevent abuse. Please message us on Discord if you need to scan more works.
