Review on Different Chaotic Based Image Encryption Techniques

2014

In present times, Due to the rapidly growth of digital and multimedia applications, more multimedia data are developed and transmitted through the networks in ,art, entertainment, advertising, education, training and commercial areas, which may have important information that should not be accessed by the general users. Therefore issue of protecting the confidentiality, integrity, security, privacy as well as the authenticity of images has become an important issue for communication and storage of images. In recent years, various encryption techniques are developed and applied to protect the confidential images from unauthorized users. This paper has a review on the aspects and existing different image encryption techniques based on chaos to design an image cryptosystem. In this paper, first a general introduction given for cryptography and images encryption and followed by discussion of different chaotic based image encryption techniques and related works for each technique reviewe...

Chaos Image Encryption Methods: A Survey Study

Bulletin of Electrical Engineering and Informatics, 2017

With increasing dependence on communications over internet and networks, secure data transmission is coming under threat. One of the best solutions to ensure secure data transmissions is encryption. Multiple forms of data, such as text, audio, image, and video can be digitally transmitted, nowadays images being the most popular and old encryption techniques such as: AES,DES,RSA etc., show low security level when used for image encryption. This problem was resolved by using of chaos encryption which is an acceptable form of encryption for image data. The sensitivity to initial conditions and control parameters make chaos encryption suitable for image applications. This study discusses various chaos encryption techniques.

A Review of Image Encryption Using Chaos based Techniques

2017

In open communication network, it is utmost crucial to keep sensitive information protected from becoming vulnerable to unauthorized access. Encryption process provides high security to the digital data content. Chaos theory has been broadly serviceable for encrypting image due to its multiple features. The discrete chaotic cryptographic system approaches are established on block and stream encryption schemes. If these two are combined the security level is significantly advanced. Chaos is used for expanding confusion and diffusion in images. Chaotic map gives benefits of large key space and high level security. In this paper, the survey of various chaos-based image encrypting techniques is done based on existing works. The paper also lays emphasis on the methodology of different techniques in detail.

Design and Implementation of Image Encryption using Chaos Theory

Due to the rise in the use of internet facility for data/information transmission, the data must be kept secured. The data to be transferred can also be an images. So that images being transmitted through the internet must also be kept much secured for gaining the trust from the users. The image encryption can be performed through many ways. The proposed method of image encryption is by mapping with the chaotic maps provided as chaos theory. The original image will be divided in to different blocks, then permute and diffuse separately at the pixel level of each block. Finally combine and diffuse the permuted image as a cipher image. The proposed method also experimented and tested to reach the current need of image encryption to maintain the security among the users.

Image Encryption Techniques Using Chaotic Schemes: A Review

2010

Cryptography is about communication in the presence of an adversary. It encompasses many problems like encryption, authentication, and key distribution to name a few. The field of modern cryptography provides a theoretical foundation based on which one can understand what exactly these problems are, how to evaluate protocols that purport to solve them and how to build protocols in whose security one can have confidence. Advanced digital technologies have made multimedia data widely available. Recently, multimedia applications become common in practice and thus security of multimedia data has become main concern. The basic issues pertaining to the problem of encryption has been discussed and also a survey on image encryption techniques based on chaotic schemes has been dealt in the present communication. The chaotic image encryption can be developed by using properties of chaos including deterministic dynamics, unpredictable behavior and non-linear transform. This concept leads to te...

PROTECTION OF IMAGE OVER INTERNET USING DIFFERENT CHAOTIC ENCRYPTION METHOD: A SURVEY

AGU International Journal of Engineering & Technology , 2017

Image security is a very important area for today's research fields. It is essential so that any data violation and corruption can be prevented. Due to the marvelous growth of information technology, security of image has become a major concern. Encryption is one of the ways to ensure high security for images. Image encryption plays an important role in the field of image security. Most of the image encryption techniques have some security and performance issues. In recent years, encryption technology has been developed quickly and many image encryption methods have been used to secure image from unauthorized access. Lots of image encryption algorithm has been executed in previous researches. The chaos based cryptographic algorithms have suggested some new and efficient ways to develop secure image encryption techniques. In this paper we will analyze some of the chaotic image encryption methods used randomly for image security in order to find out a better solution form the previous results.

An Image Encryption and Decryption using Chaos Algorithm

In a well-developed digital world, security plays a key role in transmission of images. To overcome these challenges Encryption and Decryption techniques need to be applied. In this paper we have applied the chaotic encryption and chaotic decryption on an image by doing pixel shuffling and using chaotic maps. Chaotic nature i.e., randomness property is present in both Henon map and Arnold cat map. Pseudorandom values generation plays an important key role in Henon maps and iteratively pixel shuffling is done in Arnold cat map. A sorting Technique is followed on key values produced by Henon map. By using those sorted positions, shuffle the pixel values generated by Arnold cat map iteratively. In this way the images are provided with high security for confidential transmission.
