C3P Flashcards
What is C3P?
national charity dedicated to the personal safety of all children.
Our goal is to
reduce the sexual abuse and exploitation of children,
assist in the location of missing children, and
prevent child victimization through a number of programs, services, and resources for Canadian families, educators, child-serving organizations, law enforcement, and other parties.
What is Arachnid?
In January 2017, C3P established Project Arachnid — a web platform designed to detect known images of child sexual
abuse material (CSAM) and issue removal notices to electronic service providers (ESPs) where possible.
How does Arachnid work?
Project Arachnid detects Child Sexual Abuse Material (CSAM) by crawling specific publicly accessible URLs reported to Cybertip.ca, as well as URLs on the clear and dark web known to host such content.
When media (images, videos, or archive files) are detected at a URL, the system compares the digital fingerprint of the media with a database of fingerprints from previously verified content.
If a match is found, a takedown notice is automatically sent to the content administrator or hosting provider.
Project Arachnid re-crawls the offending URL every 24 hours, sending additional notices until the content is removed. The system processes tens of thousands of images per second, surpassing traditional methods of identifying harmful material.
The fingerprints in the database primarily come from assessments by C3P analysts, other child protection organizations, and law enforcement agencies both in Canada and internationally.
