Structured phase mask.Advanced technologies such as artificial intelligence, big data, cloud computing, and the Internet of Things have changed the digital landscape, providing many new and exciting opportunities. However, they also provide ever-shifting gateways for information theft or misuse. Staying ahead requires the development of innovative and responsive security measures, and recent advances in optical technology have positioned it as a promising alternative to digital cryptography. Optical Cryptosystems introduces the subject of optical cryptography and provides up-to-date coverage of optical security schemes. Optical principles, approaches, and algorithms are discussed as well as applications, including image/data encryption-decryption, watermarking, image/data hiding, and authentication verification. This book also includes MATLAB[reg] codes, enabling students and research professionals to carry out exercises and develop newer methods of image/data security and authentication.Postgraduate students, researchers, and educators in the area of information security and optical cryptography.Also available in print.Mode of access: World Wide Web.System requirements: Adobe Acrobat Reader, EPUB reader, or Kindle reader.Dr Naveen Kumar Nishchal is currently an associate professor in the Department of Physics at the Indian Institute of Technology (IIT) Patna. He joined IIT Patna in December 2008. Dr Nishchal received his PhD degree in physics from IIT Delhi in 2005. His research interests include optical information processing, image encryption, watermarking, digital holography, interferometry, correlation based optical pattern recognition, and fractional Fourier transform-based signal processing. He is a senior member of OSA, SPIE and life fellow of Optical Society of India. He is a life member of Indian Science Congress Association and Lasers and Spectroscopy Society of India. He has authored or co-authored 60 peer-reviewed international journal papers, two book chapters, and 150 papers in various conferences/seminars/symposia.Title from PDF title page (viewed on January 6, 2020).
