Seal overlapping detecting and processing method under situation of multi-person concurrent signatures

The invention relates to a seal overlapping detecting and processing method under the situation of multi-person concurrent signatures. The method includes the steps that a server parses the current seal information so as to obtain the position information of a current seal, the length of the current seal and the width of the current seal; the server parses a current newest signature file so as to obtain the position information of all existing seals, the length of all the existing seals and the width of all the existing seals in the current newest signature file; the server judges whether the currently received seal is overlapped with the existing seals or not according to the position information of the existing seals located in front of and behind the current seal after ordering is conducted; if yes, the position of the current seal is transferred, if not, the process is ended and exited. By the adoption of the seal overlapping detecting and processing method under the situation of multi-person concurrent signatures, the overlapped seals in the multi-person signatures can be recognized and moved to a blank signature region to achieve seal separation.
