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