HEADSUP: Ofcom *tonight* to announce demand for apps, websites to deploy “hash matching” (i.e. client-side scanning, fuzzy matching) of uploaded images “to protect children”

privacy impact: logfiles of fuzzy-matching hash databases become long-term surveillance pipeline to retrospectively track whistleblower leak images, Snowden 2.0, etc; plus enabling censorship of arbitrary content.

Later on, I realised this technology could also be used to fuzzily compare texts to determine if they look similar, I tested this technology in #Diaphora as a mean to determine if two pseudo-codes are 'similar' by comparing the 3 fuzzy hashes #DeepToad calculates and it turns out it worked much better than other approaches I tested (and better than expected!) so, finally I integrated it into the public version of Diaphora.
