A collection of Trust & Safety tools from Meta for fighting digital harms, including perceptual hashing algorithms (PDQ for images, TMK and vPDQ for video) and a Python library/CLI for content scanning and signal exchange. It also includes the Hasher-Matcher-Actioner, a deployable content moderation platform for AWS, and reference examples for Meta's ThreatExchange API.

Use cases

• detect reposts of known harmful images
• match videos against a database of known content hashes
• share threat signals between platforms
• scan uploaded media for CSAM or non-consensual imagery
• deploy a content moderation hash-matching service
• query and publish threat intelligence via Meta's ThreatExchange API

When to choose

• you need perceptual hashing of images or videos for content moderation
• you want to participate in hash-sharing programs like StopNCII or NCMEC
• you need a ready-to-deploy hash-and-match platform on AWS
• you want reference implementations for the ThreatExchange API

When to avoid

• you need general-purpose cryptographic hashing or malware detection
• you want a turnkey moderation solution without operating your own infrastructure
• your use case is unrelated to media hash matching or threat signal exchange
