Wikipedia
Hash collision
In computer science, a hash collision or hash clash is when two pieces of data in a hash table share the same hash value. The hash value in this case is derived from a hash function which takes a data input and returns a fixed length of bits.Although hash algorithms have been created with the intent of being collision resistant, they can still sometimes map different data to the same hash (by virtue of the pigeonhole principle). Malicious users can take advantage of this to mimic, access, or alter data.Due to the possible negative applications of hash collisions in data management and computer security (in particular, cryptographic hash functions), collision avoidance has become an important topic in computer security.
The New Hacker's Dictionary
hash collision
[from the techspeak] (var.: hash clash) When used of people, signifies a confusion in associative memory or imagination, especially a persistent one (see thinko). True story: One of us [ESR] was once on the phone with a friend about to move out to Berkeley. When asked what he expected Berkeley to be like, the friend replied: “Well, I have this mental picture of naked women throwing Molotov cocktails, but I think that's just a collision in my hash tables.” Compare hash bucket.
