What is IntelliGrade?

In 2021 we launched IntelliGrade. IntelliGrade is a powerful tool that enables our analysts to accurately grade child sexual abuse images and videos, while automatically generating unique hashes (digital fingerprints) which are used to identify and eliminate these images wherever they appear.

What makes IntelliGrade different from other technology, is that it allows us to enrich these hashes with additional contextual metadata.

A key benefit of this enrichment process is that hashes generated by IntelliGrade are compatible with child sexual abuse laws and classifications in the UK, US, Canada, Australia, New Zealand and the Interpol Baseline standard.

This means we can provide a dataset of hashes of child sexual abuse imagery which is compatible with multiple legal jurisdictions around the world. And just like the hashes that we’ve been creating since 2016, the IntelliGrade hashes are also created in various formats including PhotoDNA, SHA1, SHA256 and MD5.

At the end of 2021, the total number of unique IntelliGrade hashes was 335,215.
