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.

New Approaches to Encrypt and Decrypt Data in Image using Cryptography and Steganography Algorithm

International Journal of Computer Applications, 2016

Nowadays, network has important roles for transferring data accurately and fast from source to a destination. The data is not secure enough to transfer highly confidential. The security of information has become one of the principle challenges of resource sharing with data communication over computer network. Cryptography and Steganography are two methods for protecting data from intruders while transferring over an open channel network. Cryptography is a method to encrypt data and steganography is the art and science of hiding secret message in a cover image. In this paper a Hash Least Significant Bit (H-LSB) with Affine cipher algorithm has been proposed for providing more security to data in a network environment. First we encrypt the data with the new cryptography algorithm and then embed in the image. Eight bits of the secret message are divided into 3, 3, 2 and embedding into the RGB pixels values of the cover image respectively. A hash function is used to select the particular position of insertion in LSB bits. This system allows a message sender to select keys to encrypt the secret message before embedding into the image and a receiver is used the keys to decrypt the message. Receiver can be decrypted the encrypt message with incorrect the keys but to a different form from the original message. This system has the ability to provide better security while transferring the secret message from one end to the other end in network environment.

A proposed model for text and image encryption using different techniques

TELKOMNIKA, 2022

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. The proposed technique relies on using square root of public key as private key. XOR operation for colored images encryption and decryption is performed. By calculating signal to noise ratio (PSNR), mean square error (MSE), and bit error rate (BER), the most important things that we address how to provide data security for large data based on encryption techniques and increase the security of multimedia data and texture date and address the problem of time and accuracy in image matching. the results show that the quality of images after decryption is good.

During storing and sharing, avoid third party access of data is the challenge one. Providing security of data is the clever work and art also. Many protection algorithms are used in recent years. Protection may be given of a data is converting the original in to some unknown form, signals, sketch etc., which is not understand by any one. Cryptography is the best technique of image data security. In Greek, 'crypto' refers 'hidden' and 'graphy' refers 'script'. Cryptography has two processes namely encryption and decryption. Encryption achieves the conversion by possessing a key of original data into unreadable form called encoding. Restoring of encrypted data in to original is decoding or decryption. Key, code or password is the vital role in cryptography. This paper presents the performance of encryption and decryption of an image using AES algorithm and tested on image and results are shown.

An Image Encryption Algorithm with XOR and S-box

2015

This new algorithm performs lossless image encryption by combining variable-length key-dependent XOR encryption with S-box substitution. This algorithm was implemented and tested by performing different permutations of XOR encryption and S-box substitution. Empirical analysis using different types of test images of different sizes showed that this new algorithm is effective and resistant to statistical attacks. The idea presented by this algorithm may be generalized to apply to input data other than images, and may be combined with other encryption methods.

Image Encryption & Decryption with Symmetric Key Cryptography using MATLAB

Any communication in the language that you and I speak—that is the human language, takes the form of plain text or clear text. That is, a message in plain text can be understood by anybody knowing the language as long as the message is not codified in any manner. So, now we have to use coding scheme to ensure that information is hidden from anyone for whom it is not intended, even those who can see the coded data. Cryptography is the art of achieving security by encoding messages to make them non-readable. Cryptography is the practice and study of hiding information. In modern times cryptography is considered a branch of both mathematics and computer science and is affiliated closely with information theory, computer security and engineering. Cryptography is used in applications present in technologically advanced societies; examples include the security of ATM cards, computer passwords and electronic commerce, which all depend on cryptography. There are two basic types of cryptography: Symmetric Key and Asymmetric Key. Symmetric key algorithms are the quickest and most commonly used type of encryption. Here, a single key is used for both encryption and decryption. There are few well-known symmetric key algorithms i.e. DES, RC2, RC4, IDEA etc. In this Project digital images encrypted and decrypted by using symmetric key cryptography using MATLAB.

A Robust Technique to Encrypt and Decrypt Confidential Data within Image

http://www.ijesi.org/, 2015

The rapid development of data transfer through the Internet made it easier to send the data accurate and faster to the destination. There are many transmission media to transfer the data to destination like e-mails; at the same time it may be easier to modify and misuse the valuable information through hacking. So, in order to transfer the data securely to the destination without any modifications, there are many approaches like cryptography and steganography. This paper deals with a new technique steganography to hide encrypted confidential data within images. Steganography is the art of hiding the fact that communication is taking place, by hiding information in other information. Many different carrier file formats can be used, but digital images are the most popular because of their frequency on the internet. For hiding secret information in images, there exist a large variety of steganography techniques. Some are more complex than others and all of them have respective strong and weak points. Different applications may require absolute invisibility of the secret information, while others require a large secret message to be hidden. This paper intends to give a brief idea about the new image steganographic approach that makes use of Least Significant Bit (LSB) algorithm for embedding the data into the bit map image.

International Journal of Advanced Computer Science and Applications

The emphasis of this work is image encoding based on permutation as well as changes that utilize Latin cube as well as Latin square image cipher meant for both color and gray images. Generally, multimedia data are transmitted in the network as well websites, numerous methods have been established for securing the information without any negotiation. Security of information in all the areas is required to ensure that the information sustains privacy, is presentable for recovery as well as governance purposes. These data can be secured by taking CIA (confidentiality, Integrity, and Availability) to realize information like confidentiality about the data that can be reserved as undisclosed from an illegal user of source, the integrity of the data is maintained unaffected for unauthorized font, availability of resources for official personal to retrieve data for access the information. Authentication of a person is by identification, conserving information and its validation of data. Implementing this authentication will store the data in the required format that is either exchanged or transmitted for the internet application. By breaching the misuse of data is can be protected for confidential as well as sensitive data. To achieve security and maintain confidentiality cryptographic methods are implemented.
