Variable length key based visual
This document proposes a variable length key-based visual cryptography scheme for encrypting color images. It involves encrypting the original image using a variable length symmetric key, generating shares of the encrypted image using random numbers, and decrypting the shares by stacking a minimum number of shares and applying the same encryption key. The proposed scheme aims to improve security over simple visual cryptography by using an encryption key and random number-based share generation, making the shares and encrypted image different from the original image. It is described as having less complex share generation than other techniques while providing security through the use of encryption and a variable length key.

7. 9589 1-pb
This document describes a new password authentication method that combines textual passwords with a modified cued click points technique for increased security. The method uses a special key display interface that breaks the user's password into a combination of four passwords plus three additional strings. These seven strings are then encrypted using a novel one-way encryption algorithm called One-time Data Division (ODD). This produces a 256-character encrypted password that is stored in the database for authentication. The encryption is complex and lossy, making the original password irrecoverable even by an administrator. The method aims to provide strong security while maintaining usability.
Security using image processing
Using image stitching and image steganography security can be provided to any image which has to be sent over the network or transferred using any electronic mode. There is a message and a secret image that has to be sent. The secret image is divided into parts.The first phase is the Encrypting Phase, which deals with the process of converting the actual secret message into ciphertext using the AES algorithm. In the second phase which is the Embedding Phase, the cipher text is embedded into any part of the secret image that is to be sent. Third phase is the Hiding Phase, where steganography is performed on the output image of Embedding Phase and other parts of the image where the parts are camouflaged by another image using least significant bit replacement. These individual parts are sent to the concerned receiver. At the receivers end decryption of Hiding phase and Embedding Phase takes place respectively. The parts obtained are stitched together using k nearest method. Using SIFT features the quality of the image is improved.

separable reversible data hiding in encrypted image
This document proposes a method for separable reversible data hiding in encrypted images. The method uses different keys for image encryption and data hiding, allowing the data and original image to be retrieved independently. This improves on existing systems that use the same key for encryption and data hiding, allowing anyone with the key to access both the hidden data and original image. The proposed method encrypts images with an encryption key, then hides data in the encrypted images with a separate data hiding key. Receivers with the data hiding key can retrieve the hidden data, and receivers with the encryption key can retrieve the original image, without extracting the hidden data.

G05124550
This document presents an optimized FPGA hardware implementation of public key cryptography using encryption and decryption. The implementation uses two keys - a public key for encryption that anyone can use, and a private key for decryption that only the intended recipient possesses. The design was tested on a Xilinx Virtex 5 FPGA. Encryption and decryption were shown to work correctly when the proper keys were used. Without the private key, decryption was not possible, demonstrating the security of the approach. Synthesis results showed the design utilizes FPGA resources efficiently compared to other related work.

This document discusses methods for encrypting and decrypting images using reversible data hiding and least significant bit algorithms with asymmetric cryptography. It proposes a method that reserves room in the image before encryption using histogram shift-based reversible data hiding and least significant bit algorithms with a public key cryptosystem. This allows data to be embedded in the encrypted image simply for the user. The embedded data and original image can then be extracted and recovered later without any loss of pixels or data. The method claims to embed more than ten times as much data as other techniques while maintaining image quality and restoration after encryption.

Image Cryptography using Nearest Prime Pixels
This document proposes a novel image cryptography method using nearest prime pixels for key generation. It begins by introducing image cryptography and its basic concepts. The proposed method first converts image pixels to digital values and finds the nearest prime pixel values. Keys are generated by taking the difference between original and nearest prime pixels. Encryption is done by XORing pixels with keys and reversing the results, which are stored column-wise in a matrix. Decryption retrieves the matrix rows and performs reverse operations to recover the original image. The method aims to improve security by using mixed row/column retrieval and complementary operations during encryption and decryption.
Biomedical image transmission based on Modified feistal algorithm
This document presents a high-performance hardware implementation of a biomedical image encryption system using a modified Feistal algorithm. The encryption algorithm is based on DES with a novel key scheduling technique. The encrypted images are unintelligible but have high clarity when decrypted. The system is implemented on an FPGA and achieves an encryption rate of 35.5 Gbit/s. It uses different keys each clock cycle, making the encrypted images very difficult to break.
secure Audio Data Transfer Over Internet Using Steganography
This document proposes a method for securely transferring audio data over the internet using steganography. It involves encrypting an audio/speech signal, generating a secret key, and hiding the encrypted signal in cover image files by modifying the least significant bits of pixels. The encryption is performed at the bit-level of the audio data to increase security. At the receiver end, the authorized person can decrypt the hidden audio by correctly entering the secret key. The goal is to develop a robust encryption algorithm that reshuffles and secretly arranges the audio signal bits within the cover image bits to achieve greater encryption strength. Various encryption techniques and literature on related work in audio steganography and cryptography are discussed.

This document proposes a system that combines visual cryptography and steganography to provide multiple levels of security. It aims to overcome the limitations of single-level hiding approaches. The proposed system first encrypts a secret message using RSA encryption and then hides the cipher text in an image using steganography. This stego image is transmitted along with a cover video. The receiver extracts the stego image from the video and decrypts the cipher text using their private key to retrieve the original secret message. The system implements visual cryptography to allow decryption through human vision without requiring any computation.
Secure Image Hiding Algorithm using Cryptography and Steganography
This document proposes a secure image hiding algorithm using cryptography and steganography. It first encrypts an image using the Blowfish encryption algorithm. Then, it hides the encrypted image in a video file using least significant bit (LSB) steganography. Blowfish was chosen for encryption due to its strong security and fast processing compared to other algorithms. LSB steganography in BMP images provides high invisibility and payload capacity. The proposed method provides two layers of security by encrypting the image before hiding it, making it difficult for unauthorized users to detect or extract the hidden information.

Video Encryption and Decryption with Authentication using Artificial Neural N...
Abstract :Multimedia data security is becoming important with the continuous increase of digital communications on internet. With the rapid development of various multimedia technologies, more and more multimedia data are generated and transmitted in the medical, commercial, and military fields, which may include some sensitive information which should not be accessed by or can only be partially exposed to the general users. . The encryption algorithms developed to secure text data are not suitable for multimedia application because of the large data size and real time constraint. Therefore, there is a great demand for secured data storage and transmission techniques. Information security has traditionally been ensured with data encryption and authentication techniques. The secrecy of communication is maintained by secret key exchange. In effect the strength of the algorithm depends solely on the length of the key. The presented work aims at secure video transmission using randomness in encryption algorithm, thereby creating more confusion to obtain the original data. The security of the original cipher has been enhanced by addition of impurities to misguide the cryptanalyst. Since the encryption process is one way function, the artificial neural networks are best suited for this purpose as they possess features like high security, no distortion and its ability to perform for non linear input-output characteristics, In the presented work the need for key exchange is also eliminated, which is otherwise a perquisite for most of the algorithms used today. The proposed work finds its application in medical imaging systems, military image database communication and confidential video conferencing, and similar such application. The results are obtained through the use of MATLAB 7.14.0 Keywords: Artificial Neural networks, Back propagation algorithm, video encryption and decryption, cipher and decipher.

Since the encryption process is one way function, the artificial neural networks are best suited for this purpose as they possess features like high security, no distortion and its ability to perform for non linear input-output characteristics, In the presented work the need for key exchange is also eliminated, which is otherwise a perquisite for most of the algorithms used today. The proposed work finds its application in medical imaging systems, military image database communication and confidential video conferencing, and similar such application. The results are obtained through the use of MATLAB 7.14.0 Keywords: Artificial Neural networks, Back propagation algorithm, video encryption and decryption, cipher and decipher.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

Picture arithmetic cryptosystem using symmetric key enhanced algorithm with legitimate pictures-abstract
- 1. PICTURE ARITHMETIC CRYPTOSYSTEMS USING SYMMETRIC KEY ENCHANCED ALGORITHM WITH LEGITIMATE PICTURES ABSTRACT The secret messages passed through network are hacked and algorithms are not efficient to the expected level. A powerful encryption technique is introduced and performs a large variety of generating keys to encrypt the message in the form of pictures. The arithmetic operations are performed over the picture key to make the technique even more powerful. First encryption is done with the help of vigenere cipher and the key is generated through picture. Second encryption is done with the help of newly designed 10x26 table and the key is generated from the first key. The decryption is done by the reverse of encryption process.
- 2. EXISTING SYSTEM The cryptographic systems use the key to encrypt messages in the form of text or string. Vigenere cipher can be broken using counting diagram.Total number of combinations required to break the system using counting diagram is very small. Large key size makes the system less efficient. The secret key to perform encryption is more reliable to attack because it is an easily recognizable format. PROPOSED SYSTEM The encryption of the message is done using the picture key which is difficult to break. Total number of combinations required to break the system exceeds hundred digit number and more with increase in number of pictures. The system performances increases with increase in key size. The system uses two main operations to make the key stronger. The first operation is LOCK-10(Logical Crypto Key)is performed over the secret code to get the picture sorting key.LOCK-10 involves 10 different operations and these are performed over the secret code to get the picture sorting key. The operation LOCK-10 can be performed in 10 factorial ways .The picture sorting key is obtained and the ‘N’ pictures are arranged in one of the ‘N’ factorial ways. The PACK(Picture Arithmetic Crypto Key) operation is performed over the picture key to get the first key. The second key is generated from the first key by performing LOCK-5 operation over the first key. The vigenere encryption is performed over the first key and encryption is performed over the second key with the help of 10x26 matrix. Increase in number of pictures used for ciphering, increases the system performance proportionally.
