ImageNet contains naturally occurring NeuralHash collisions

SUMMARY NeuralHash, the perceptual hashing model behind Apple's client-side CSAM detection system, is designed so that two distinct images should never share the same 96-bit hash. A search through ImageNet uncovered two naturally occurring image pairs with identical NeuralHashes, independent of the adversarially crafted collisions researchers

Mitigating the Collision of Apple's CSAM NeuralHash

SUMMARY Researchers reverse-engineered Apple's NeuralHash model and demonstrated that adversarially crafted images could be made to share a hash with an unrelated target image, potentially flooding Apple's human review queue with false positives. Running the colliding image pairs through OpenAI's CLIP shows that

Choosing the Right Problem Statement

SUMMARY Before picking a model or sourcing images, defining a well-scoped problem statement is the step that determines whether a computer vision project succeeds. A good problem statement is specific (naming exact objects to detect), achievable (accounting for annotation feasibility and domain expertise), and measurable (informing deployment strategy and
