| Popis: |
The use of digital image in a variety of disciplines has skyrocketed, particularly in multimedia, medicine, and social media. The integrity and confidentiality of digital images communicated over the internet can be jeopardized by a variety of security threats. As a result, the content of these digital images must be preserved at all costs for a variety of domain-specific applications. Visual cryptography scheme (VCs) is an image-based approach to encrypt the secret image in such a way, and human visual system (HVS) can be used to decrypt the image. The core concepts of visual cryptography and applications of several visual cryptography schemes are covered in this chapter. The authors describe a unique reversible data hiding method for protecting secret shares using a covering subset and recovering the secret image using an overlaying technique. This chapter also covers a comparative analysis of 2-out-of-n and 3-out-of-n visual cryptography schemes. |
