Lensless Optical Encryption of Multilevel Digital Data Containers Using Spatially Incoherent Illumination

Abstract

The necessity of the correction of errors emerging during the optical encryption process led to the extensive use of data containers such as QR codes. However, due to specifics of optical encryption, QR codes are not very well suited for the task, which results in low error correction capabilities in optical experiments mainly due to easily breakable QR code’s service elements and byte data structure. In this paper, we present optical implementation of information optical encryption system utilizing new multilevel customizable digital data containers with high data density. The results of optical experiments demonstrate efficient error correction capabilities of the new data container.

“…Chen et al [20] proposed an exciting optical image encryption method based on spatial nonlinear optics, which realized the high degree of freedom to explore and apply light and provided new research prospects for the development of optical encryption for the protection of information in various optical structures and optical materials. Cheremkhin et al [21] proposed the optical implementation of an information optical encryption system using a new multi-level customizable digital data container with high data density, which has efficient error correction ability. Kumar et al [22] propose two-dimensional XORor-logic manipulation of beams carrying optical vortex arrays, which brings new possibilities for high-dimensional data processing, cryptography, and computing.…”

“…Image encryption based on neural networks and cellular automata has a large key space and good noise resistance because of the nonlinear or self-organizing nature of the encryption system. In addition, there are image encryption algorithms based on DNA [7][8][9][10][11], RNA [12][13][14][15][16], image selectivity [17], optical encryption system [18][19][20][21][22] and random grid [23][24][25][26][27] visualization.…”
