International Journal of Scientific Research in Science, Engineering and Technology, 2022

Digital images are crucial in many areas, including online communication, multimedia systems, medical imaging, and military communications. Color images are being stored and transmitted over the internet and wireless networks in large amounts and thus it is necessary to protect them from any unauthorized user access. Cryptography is the art of codifying messages, so that the messages become unreadable, this way it plays a vital role in the field of security of data. There are several Cryptographic Algorithms to encrypt and decrypt Images. This paper aims to Encrypt and Decrypt Images based on RSA Algorithm providing Authentication and using Image Hash functions for additional Security and Integrity of images. This project also makes sure the Image retains its quality and is not corrupted even after decryption.

A Study and Modified Key Based Image Encryption using RSA Algorithm

Now a day's data security is one of key issue in information security whether it is image, audio, text etc. We are sharing image files for many causes like identity information, medical diagnosis, and study on space related issues so while we do transfer images there should be some defensive security mechanism in order to stand against vulnerably attacks on image data. There exists various techniques in cryptography for encryption of images. In this paper we studied various image encryption methods and proposed a more secured Encryption with incorporating RSA algorithm in Password key generation and we have passed same key in consecutive steps of bit rotation, extended hill cipher, modified vernam cipher, modified MSA algorithm in order to improve security of password key as well as Image encryption method.

Visual Cryptography with RSA Algorithm for Color Image

International Journal of Engineering & Technology, 2018

RSA algorithm founded by Rivest, Shamir and Adleman is an algorithm that based on the use of factorization of a significant number to its factor, and the element must be the prime number. Factorization used to find the private key. In this paper, the RSA algorithm will be used in a visual cryptographic to encrypt and decrypt a color image. The test will conduct with five different photos. Assessment performed using Structural similarity (SSIM) to compare the matrix value of the initial image with the decrypted image. SSIM generates a value of 1 on all pictures. The proves that the Matrix Value in the initial and after decoded images has the same amount. The image decryption will worsen; can be seen from the smaller SSIM value.

Color Image Encryption for Secure Transfer over Internet: A survey

International Research Journal of Engineering and Technology (IRJET) , 2017

With the tremendous and rapid growth of information interchange through internet transmission, information security has become a major issue to deal with. As because images are being used more in business and industrial process, military and medical and also in scientific researches, it has become the important factor to protect the confidential image data from unwanted access or intruders. Because of development of technology, the hacking techniques, and attacks are also becoming more and more intelligent. As a result, traditional approaches of image encryption are failing to be a good competitor with the attackers. Image encryption has been a wide area of research field. The protection of image data is more important because it contains maximum features of a person or thing. Image encryption is employed to protect an image from unauthorized access and increase image security over internet. Nowadays Internet is used for transmitting and storing huge amount of information. Since the internet has many loopholes and several scopes of hacking or being attacked by intruders. So, our personal and private image need to be protected during transmission over internet. Researches have done satisfactory numbers of researches and developed lots of image encryption algorithms till now. In this paper, we illustrated a brief survey of some significant works regarding image encryption techniques in different domains and our main perspective will be to come up with a better solution to make images more secure in the future.

Data security and protection is one of the most common technologies used in the field of computer science. This is because of its great importance in all fields related to daily life, whether political, economic, and other aspects change. In this research paper, a new intelligent system that concentrates on image and text encryption and decryption is proposed. Furthermore, the image recognition rate is increased. In this paper, the Rivest Shamir Adleman 3 key (RSA3k) algorithm is used but in a new technique to encrypt and decrypt text.

An Advance Approach of Image Encryption using AES, Genetic Algorithm and RSA Algorithm

In current scenario the entire world is moving towards digital communication for fast and better communication. But in this a problem rises with security i.e. when we have to store information (either data or image) at any casual location or transmit information through internet. As internet is an open transmission medium, security of data becomes very important. To defend our information from piracy or from hacking we use a technique and i.e. known as Encryption Technique. In this paper, we use image as information and use an advance approach of well-known encryption techniques like AES, Genetic Algorithm, and RSA algorithm to encrypt it and keep our information safe from hackers or intruders making it highly difficult and time consuming to decipher the image without using the key.
