Cloud Data Storage Confidentiality Using Steganography and Visual Cryptography: A Review

Cloud computing security has emerged as one of the most significant trends in the information technology (IT) sector, and it is currently widely used in that sector, particularly with the growth of information in the cloud. The security of data stored in the cloud, and when it is transferred between users and servers, is very important. secure communication and data transfer can be achieved through the use of steganography and visual cryptography. It is one of the most important technologies for securing data and authenticating it so that only the sender and the receiver can be aware of the hidden information as well as transmitting it. In contrast, visual cryptography is a cryptographic technology that encrypts data. By having these two different branches, it is difficult for an attacker to compromise the data's confidentiality. The purpose of this paper is to review several steganography and visual cryptography that have been proposed to improve cloud security and make it more secure against cyberattacks and eavesdropping. The primary goal of this study is to investigate the capabilities of secured data, which are frequently employed by researchers. Additionally, each secured data domain's advantages and disadvantages are investigated. In order to strengthen the security mechanisms, this research concludes that visual cryptography approaches could be combined with steganography and cloud computing in the secured data realm.
