WebNeuralHash is a perceptual hash function that uses a neural network. Images are resized to 360x360 and passed through a neural network to produce a 128-dimensional feature vector. Then, the vector is projected onto R^96 using a 128x96 "seed" matrix. Finally, to produce a 96-bit hash, the 96-dimensional vector is thresholded: negative entries ...

WebA Hash Collision Attack is an attempt to find two input strings of a hash function that produce the same hash result. Because hash functions have infinite input length and a predefined output length, there is inevitably going to be the possibility of two different inputs that produce the same output hash. If two separate inputs produce the same hash … WebThe hash function’s properties should match Git’s needs (e.g. Git requires collision and 2nd preimage resistance and does not require length extension resistance). As a tiebreaker, the hash should be fast to compute (fortunately many contenders are faster than SHA-1). caged bird with blood on the bars
