minus-squarevrighter@discuss.tchncs.delinkfedilinkarrow-up7·3 个月前because of the “perceptual” part. A normal hash has the property that it produces wildly different hashes for even the tiniest of changes in the file. Perceptual hashing flips that requirement on its head, and therefore makes finding a suitable hash function much harder.
