In this work the first tailor made data container for optical encryption is presented. The results demonstrate that this tailor made container presents larger noise tolerance and lower experimental requirements than QR codes in optical encryption. Therefore, a tailor made information container offers great potential for optical security techniques that were considered of limited practical application due to the presence of noise. Computer simulations and experimental results using the joint transform correlator encrypting architecture are presented to demonstrate the validity, advantages and applicability of the proposal.
