Due to advancements in technology, digital images are widely used in various applications like medical field, military communication, remote sensing, etc. These images may contain sensitive and confidential information. Therefore, images are required to be protected from unauthorized access. Many image protection techniques have been proposed in past years. The most common technique to protect the images is encryption. In this technique, a secret key and an encryption algorithm are used to change the plain image into an encrypted image. The encrypted image looks like a noisy image and can easily attracts the attacker's attention. If image gets captured and stacked, sensitive information can be revealed. In this regard, Visually Meaningful Encrypted Image (VMEI) technique is developed, which initially encrypts the original image and then hides it into a reference image. The final encrypted image looks like a normal image. Hence, VMEI technique provides more security as compared to simple image encryption techniques. Therefore, a systematic survey on existing VMEI techniques is presented in this paper. The VMEI techniques are divided into different categories based on their characteristics. Moreover, this paper elaborates and investigates the improvements and analyses performed on VMEI techniques based on various evaluation parameters. These evaluation parameters are divided into different categories such as security attacks, encryption key attacks, quality analysis, and noise attacks. Finally, this paper discusses the potential applications and the future challenges of VMEI techniques.

“…However, when phase masks are considered as secret keys in the traditional Fourier transform-based DRPE, images containing plaintext contours can be retrieved using conventional attacks such as known-plaintext attack. To address this issue, traditional DRPE has been further extended to different domains including fractional Fourier domain [2][3][4] , Fresnel domain 5,6 , and rotator domain 7,8 . Thus, the key-space size can be greatly increased, which makes DRPE more complex and secure.…”

An optical image encryption method is proposed based on Fourier single-pixel imaging and iterated phase retrieval algorithm. First, a binary barcode image containing two groups of horizontal strips is randomly generated and used as the target image in the single-pixel imaging process. Second, considering the barcode image as the amplitude constraint, the original plaintext image is encoded to two phase-only masks using a designed phase retrieval algorithm in Fresnel domain, and these masks are applied as secret keys. Finally, the barcode image is encrypted to a series of measurements using two-step phase shift Fourier single-pixel imaging as the ciphertext. Differing other methods, the original image is not directly imaged and encoded into the ciphertext. Even the ciphertext is obtained by a cracker, only the barcode image may be further discovered. Due to two phase-only masks as secret keys, the security level of the cryptosystem can be enhanced greatly. The simulated results verify the feasibility of the proposed method, and this work provides an effective alternative for the related research.

“…Among them, the double random phase encoding (DRPE) provided a new research perspective, with which a noisy ciphertext can be obtained by encrypting a plaintext image along with two statistically independent random phase-only masks. In order to enhance the ability to resist some common attacks, DRPE has been applied in various domains, including Gyrator domain [ [5] , [6] , [7] ], Fresnel domain [ 8 , 9 ], fractional Fourier domain [ [10] , [11] , [12] ], and so on. Furthermore, various methods based on different kinds of optical theories and technologies, such as fractional Mellin transform [ 13 ], interference [ 14 , 15 ], transport of intensity equation [ 16 ], hologram [ 17 , 18 ], data container [ 19 ], iterative algorithm [ 20 , 21 ], photon-counting [ 22 ], monocular depth rendering [ 23 ], holography [ 24 ], image denoising [ 25 ], single-pixel imaging [ 26 ], and binary tree-sliced pattern [ 27 ], have been reported in recent years.…”
