Facebook, Microsoft, Twitter and YouTube are coming together to help curb the spread of terrorist content online. There is no place for content that promotes terrorism on our hosted consumer services. When alerted, we take swift action against this kind of content in accordance with our respective policies.
Starting today, we commit to the creation of a shared industry database of “hashes” — unique digital “fingerprints” — for violent terrorist imagery or terrorist recruitment videos or images that we have removed from our services. By sharing this information with each other, we may use the shared hashes to help identify potential terrorist content on our respective hosted consumer platforms. We hope this collaboration will lead to greater efficiency as we continue to enforce our policies to help curb the pressing global issue of terrorist content online.
Our companies will begin sharing hashes of the most extreme and egregious terrorist images and videos we have removed from our services — content most likely to violate all of our respective companies’ content policies. Participating companies can add hashes of terrorist images or videos that are identified on one of our platforms to the database. Other participating companies can then use those hashes to identify such content on their services, review against their respective policies and definitions, and remove matching content as appropriate.
As we continue to collaborate and share best practices, each company will independently determine what image and video hashes to contribute to the shared database. No personally identifiable information will be shared, and matching content will not be automatically removed. Each company will continue to apply its own policies and definitions of terrorist content when deciding whether to remove content when a match to a shared hash is found. And each company will continue to apply its practice of transparency and review for any government requests, as well as retain its own appeal process for removal decisions and grievances. As part of this collaboration, we will all focus on how to involve additional companies in the future.
Throughout this collaboration, we are committed to protecting our users’ privacy and their ability to express themselves freely and safely on our platforms. We also seek to engage with the wider community of interested stakeholders in a transparent, thoughtful and responsible way as we further our shared objective to prevent the spread of terrorist content online while respecting human rights.
