Each of a first portion and a second portion of data is selected. Each of the first portion and the second portion of data are in the human-readable format and capable of being converted from a human-readable format to an electronically readable format. The first portion of data is encrypted and stored in a first electronically readable medium and the second portion of data is encrypted and stored in a second electronically readable medium, wherein the first electronically readable medium does not match with the second electronically readable medium. Each of the first portion and the second electronically readable medium is incorporated into the printed publication. The first portion of data is read from the first electronically readable medium using a first data reading device without removing the first electronically readable medium from the printed publication. The second portion of data is read from the second electronically readable medium using a second data reading device without removing the second electronically readable medium from the printed publication. |
