Abstract
A computer utilizes a matrix code to securely communicate information. To utilize the matrix code, the computer receives a scan of the matrix code, and identifies a first mask within a data region of the matrix code, wherein the first mask includes public user data, and identifies a second mask within the data region of the matrix code, wherein the second mask include private user data. The computer decodes the public user data and the private user data from the matrix code, and decrypts one or both of the public user data and the private user data. The computer also removes a distortion operation from the second mask, wherein removing the distortion operation includes reversing a transformation, rotation, skew, shear, reflection, or projection operation.
