A Comprehensive Review About Image Encryption Methods

Harran Üniversitesi Mühendislik Dergisi, 2022

In today's technology world, data security has a great importance. Because each data type has its own characteristics, there are various methods of providing this security. The main subject of this study is the security of image data which are more complex structures than text data. Using traditional encryption methods alone to ensure security in image data types can create security weaknesses. For this reason, nowadays, some traditional methods are combined with each other or different methods to encrypt image data. In this study, 131 articles were examined and image encryption methods were classified according to the traditional methods, some new methods or combinations of some methods, that they contain. Studies on both colored and gray level images have been handled together. Finally, the images used in the articles were compared with each other in many ways and the results were presented graphically.

A Novel Encryption Method for Image Security

Image encryption is one of the most methods of information hiding. A novel secure encryption method for image hiding is presented in this paper. The proposed method provides good confusion and diffusion properties that ensures high security due to mixing the two Boolean operations: XOR and Rotation that are done on the bits of the pixels in the image. This method is implemented by firstly doing a sequential XOR operation on all the bits of pixels in the image, and secondly makes a circular rotate right of these bits. These two operations are repeated many times during the encryption phase. The security and performance of the proposed encryption method have been evaluated by applying it on images and analyze the recorded results using key space analysis, key sensitivity analysis, and statistical analysis. The performance experiments show that the proposed method is promising to use effectively in wide fields of image encryption.

A Survey Paper on Image Encryption Techniques

IJSRD, 2013

Security is an important issue in digital data transmission and storage. The security can be provided by image encryption. Encryption is one of the ways to provide high security when images are transmitted over the network. Image encryption techniques scrambled the pixels of the image and decrease the correlation among the pixels, so that we will get lower correlation among the pixel and get the encrypted image which is hard to understand. There are so many different image encryption techniques available to protect confidential image data from unauthorized access. Image encryption techniques which provide transmission of digital images in more secure way. Encryptions algorithms that are good for textual data may not be suitable for multimedia data because images contain large data. This paper present survey of various encryption methods with its advantages and disadvantages.

A Novel Method for Encryption of Images based on Displacement of RGB Pixels

2017

In today’s world, security of information has become a crucial part of every aspect of human-life, when data is transferred through internet. Due to the transmission of information through network, unauthorized access is possible. Image Encryption is one of the techniques to protect the images over the internet. This can be possible by displacement of RGB pixels of an image. Encryption can prevent a third party from understanding the data during the transmission. This paper sets out to contribute to the general body of knowledge in the area of cryptography application and by developing a RD algorithm for image encryption by shifting the RGB pixel values. The algorithm ultimately makes it possible for encryption and decryption of the images based on the RGB pixel. The algorithm was implemented using JAVA.

A Survey on Existing Image Encryption Techniques

In today's technical World people always concern with security of data before sending it over the internet. Security of data provides protection to data from unauthorized access. There is large no. of algorithms are available to secure the data. Cryptography plays a key role in data security. In modern cryptographic system encryption techniques are most widely in use. It provides security to data so that it can be used in confidential area like military, net banking, online transactions, medical, scientific etc. In this paper we mainly focus on some existing encryption techniques. Every technique comes with its good and bad features. It gives a brief review to researcher to choose a particular type of encryption scheme for some selected type of data so that it can be efficient and more secure.

In the present world when whole web is now coming on from text data to multimedia data, one of the major security concerns is the protection of this multimedia data. Image, which covers the highest percentage of the multimedia data, its protection is very important. This can be achieved by Image encryption. There are so many different techniques should be used to protect confidential image data from unauthorized access. In this paper, I had done the literature review on existing work which is used different techniques for image encryption from 1999 to 2011 and also given general introduction about cryptography and encryption.

Review of Image Encryption using Different Techniques

Academic journal of Nawroz University, 2022

Encryption is one of the measures that ensure the security of images used in various fields such as military understanding, secure clinical imaging offices, Internet and intranet media, electronic banking, and individual association images such as Facebook, WhatsApp, Twitter, etc. On this huge number of images that are sent in a free and open link either during selection or messaging; Then their security ends up being a central need in individual insurance organizations and the arrangement. This article audits and summarizes various image encryption systems to further develop advanced image encryption strategies that operate with expanded flexibility and security.

An Efficient and Highly Secure Technique to Encrypt and Decrypt Color Images

Engineering, Technology & Applied Science Research

Digital color images are considered as the most widely used data. They are exchanged frequently on the internet and via email, so an efficient and highly secure method of color image encryption and decryption is needed. Different methods of encryption-decryption are used, but most of them suffer from low efficiency or low-security level or both. In this paper, an efficient and highly secure method of encryption-decryption will be proposed, tested, and implemented. The efficiency parameters will be calculated and compared with other methods’ parameters to prove the efficiency of the proposed method.

A new encryption algorithm for image cryptosystems

Journal of Systems and Software, 2001

There are two major dierences of the characteristics of the text data and image data. One dierence is that the size of image data is usually much larger than that of text data. The other is that plain data rarely permit loss when a compression technique is used, but image data do. In this paper, we design an ecient cryptosystem for images. Our method is based on vector quantization, which is one of the popular image compression techniques. Our method can achieve the following two goals. One goal is to design a high security image cryptosystem. The other goal is to reduce computational complexity of the encryption and decryption algorithms. Ó
