Google chrome updates nytimes2/16/2023 Google has not revealed the accuracy of this AI technology. It is not clear what technology was used to identify CSAM in the reported cases. Google also notes that content identified as CSAM by its machine learning technology is “then confirmed by our specialist review teams”. Google made technology available for free to NGOs and its industry partners at the time of the announcement. The advantage here is that you can find content that might not be part of the hashed database. The technology relies on machine learning and deep neural networks for image processing. It notes that these “machine learning classifiers can discover never-before-seen CSAM”. If a similar hash is found for another photo or video, then it likely is CSAM, and the content in question is flagged.īut Google also deploys machine learning tools to search for CSAM, and it had first announced this back in 2018. What hash matching does is that the company does not store the CSAM itself, but a value or hash that represents the image, video or content in question. Companies like Microsoft, Facebook, Apple also deploy similar techniques. Google is not the only one using this hash matching technology. Basically, every time Google detects an image potentially identified as CSAM, it is assigned a hash or numeric value, and then it is matched against an earlier hash from an existing database. This particular API can also be used by other NGOs, companies to find CSAM by matching it against Google’s databases. CSAI Match is technology deployed on YouTube to fight videos of child abuse, and can spot “re-uploads of previously identified child sexual abuse material in videos,” according to Google. The first technology is hash matching, and this includes YouTube’s CSAI (Child Sexual Abuse Imagery) match technology. Remember, your Google account is linked to all these services. This applies to photos, videos, and files you might upload on Google Drive, Google Photos, etc. But it is primarily using two main technologies to scan and tag CSAM.
