The article describes how to create a blind signature on the documents submitted text-graphic lot graded images based on the matrix affine ciphers. We propose a matrix algorithm for creating signatures, mathematical models and formulas for the matrix transformations including cryptographic encryption and decryption. The procedures and programs generating matrix of keys and the encryption and decryption algorithms for the simulation results demonstrated a blind signature on the specific dimension of the images 704Х572 pixel in the software environment MathCad
