The article presents additional options for development of the previously described method [3] of covertly transmitting a QR code using steganography, which may be required for delivery of information related to the transportation process and other tasks solved in transport. In particular, a new detailed option of application of different mathematical methods used in various scientific fields (for example, multi-grid method for difference approximation of the Dirichlet boundary-value problem for the Poisson equation with a high degree of accuracy) was proposed. An effective iterative formula was constructed for cases of complex sources distribution. The method reduces the number of iterations and the likelihood of an error when restoring the original and allows to create a respective application software.
