Paper Abstract

The distribution of the encrypted information at the output of an encoding system is of major concern. When the encrypted information is conveyed to the final user, the finite size of the recording medium affects the quality of the encoded information. In this case, we face possible information degradation when recovering. In the present contribution we focus our attention on the finite size of the recorder medium in an actual experimental situation. In order to improve the quality of the decrypted data, we study the role that both the scattering element size of the masks and the input object size play in the encrypting system. Therefore, we analyze the optimal spatial distribution of the encoded information at the output of a 4f encrypting system. We present examples that support our proposal.
