WebJul 6, 2024 · The purpose of steganography is to conceal and deceive. It is a form of covert communication and can involve the use of any medium to hide messages. It’s not a form of cryptography, because it doesn’t involve scrambling data or using a key. Instead, it is a form of data hiding and can be executed in clever ways. WebMar 1, 2024 · This Spotlight provides a brief overview of the field and highlights some of the key technical results in optical encryption systems. It opens with a historical review of steganography, watermarking, and some of the classical cryptographic methods: the Data Encryption Standard, Advanced Encryption Standard, and RSA algorithm. WebThe security of ghost steganography is enhanced by applying the RSA asymmetric cryptography into the intensity signals encoding process. • This work can extend the GI applications into the steganography region, and also can enrich the knowledge of symmetric-asymmetric optical cryptography. tealight mum makinesi
