摘要: A verification picture generation method and device, a server, which belong to the technical field of computers. According method, by way generating first noise point on codes in some regions an initial second backgrounds other regions, points cannot be filtered machine through simple algorithms, so that difficulty for recognize is increased, risk cracking reduced, thereby having relatively high anti-cracking capability.
