The invention relates to the technical field of information transmission, in particular to an information transmission verification method and system. The system firstly forms data information into acalculation information body; a plurality of n*m-order matrixes are formed; the n*m-order matrix and a preset line array are converted for multiple times to obtain a multi-level check code; the acquisition end sends the acquired data information and the multi-level check code to a receiving end; the receiving end also adopts a preset line array to carry out conversion for multiple times to obtaina corresponding multi-level check code; and the multi-level check code is compared with the multi-level check code of the acquisition end to find out error data. According to the information transmission verification method, deep mining analysis can be carried out on real-time data and historical data, the development and operation rules of all the data are mastered, planning of the data information is optimized, global control over the data information and optimal control over system resources are achieved, and the safety and reliability of the data information are improved.
