Secure Data Access in Cloud Environments Using Quantum Cryptography

Cloud computing has made storing and accessing data easier but keeping it secure is a big challenge nowadays. Traditional methods of ensuring data may not be strong enough in the future when powerful quantum computers become available. To solve this problem, this study uses quantum cryptography to protect data in the cloud environment. Quantum Key Distribution (QKD) creates secure keys by sending information using quantum particles like photons. Specifically, we use the BB84 protocol, a simple and reliable way to make secure keys that cannot be stolen without detection. To protect the data, we use the Quantum One Time pad (QOTP) for encryption and decryption, ensuring the data stays completely private. This study shows how these Quantum methods can be applied in cloud systems to provide a strong defense against hackers, even if they have access to quantum computers. The combination of QKD, BB84, and QOTP creates a safe and reliable way to keep data secure when it is stored or shared in the cloud. Using quantum cryptography, this paper provides a way to ensure data security now and in the future, making cloud computing safer for everyone to store their data securely and safely.

Encryption and encoding of facial images into quick response and high capacity color 2d code for biometric passport security system

In this thesis, a multimodal biometric, secure encrypted data and encrypted biometric encoded into the QR code-based biometric-passport authentication method is proposed for national security applications. Firstly, using the Extended Profile - Local Binary Patterns (EP-LBP), a Canny edge detector, and the Scale Invariant Feature Transform (SIFT) algorithm with Image File Information (IMFINFO) process, the facial mark size recognition is initially achieved. Secondly, by using the Active Shape Model (ASM) into Active Appearance Model (AAM) to follow the hand and infusion the hand geometry characteristics for verification and identification, hand geometry recognition is achieved. Thirdly, the encrypted biometric passport information that is publicly accessible is encoded into the QR code and inserted into the electronic passport to improve protection. Further, Personal information and biometric data are encrypted by applying the Advanced Encryption Standard (AES) and the Secure Hash Algorithm (SHA) 256 algorithm. It will enhance the biometric passport security system.
