Since the beginning of time, humans have had secrets, and individuals have always been curious to learn about them. People transmit digital data to convey secret information in a variety of methods, such as text messages, secret images, and email conversations as internet technology advances. A concrete instance of a cryptography technique is visual cryptography, which allows secret images to be encrypted and decrypted by the human vision without making use of computers. Many researchers have surveyed the secret sharing schemes with factors like pixel expansion, computational complexity, threshold security, contrast and quantity of secret images. This chapter presents a survey on review and performance evaluation of several visual secret sharing schemes. Moreover, the basic overview of methods which adopt the concept of quantum cryptography with secret sharing schemes are presented with comparative study of recent research trends.
