Enhancing Information Security and Privacy by Combining Biometrics with Cryptography

Abstract

Securing information during its storage and transmission is an important and widely addressed issue. Generally, cryptographic techniques are used for information security. In cryptography, the general idea is to transform the information during a phase called encryption, before being stored or transmitted, based on a secret key. This secret key is required in order to retrieve the information from the transformed data during decryption. These secret keys are generally too long for a user to remember, and therefore, need to be stored somewhere. The drawback of cryptography is that these keys are not strongly linked to the user identity. In order to strengthen the link between the user identity and his cryptographic keys, biometrics is combined with cryptography. iii I would like to thank Ashish Gupta for his help, support, and encouragement throughout my stay here. I also thank Dr. Sandoche Balakrishnan, Dr. Mahendiran Prathaban, and Dr. Manoj Panda for making my stay in France easier. I also thank my friends Bhushan Patil, Baghyesh Patil, Dhiraj Magare, and Bapusaheb Chavan for their help during various stages of my career. I also thank my friends Avinash, Yogesh, Prashant, Chandra, and Dipak for the emotional support. Finally, I owe whatever I am to my parents Mr. Ganesh and Mrs. Mangala Kanade, and also to other members of my family, my grandmother Triveni, brothers Deepak and Ajay, sisters-in-law Savita and Snehal, nephews Dhruv and Avaneesh, and niece Krutika. Their constant support and sacrifices have made this thesis possible.

Revocable Crypto-Biometric Key Regeneration Using Face Biometrics, Fuzzy Commitment, and a Cohort Bit Selection Process

“…In addition, in the case the key is compromised, the user will not be able to create a new one. Thus, to ensure that the regeneration scheme is revocable, we used the shuffling scheme proposed by [24].…”

“…To protect template data, we adopt the shuffling scheme introduced by Kanade et al in Ref. [24]. This scheme employs a binary shuffling key, which due to its length, is either securely stored on a dedicated token or derived through a password-based mechanism.…”

“…In the context of our application, namely, crypto-biometric key regeneration, we have opted for a block size of "1", rather than "7" employed in [24]. This choice provides two primary advantages.…”

A Critical Examination of Shielding the Cyberspace: A Review on the Role of Ai in Cyber Security

“…Though they are good to some extent, traditional security tools are not strong enough to cope with the creative strategies of cyber hooligans. Hence, integrating AI technology has been considered an essential solution to the advanced threats emerging in the dynamic context, helping to identify the targets more precisely within a timely manner and even react to the threats in a quicker and real-time approach [2]. The positive sides of AI in the cybersecurity sector are undeniable; however, AI carries a plethora of challenges and ethical concerns, which calls for an unstinted examination.…”

“…AI cybersecurity will be more effective in countering cyber crimes as long as the network of cybersecurity mechanisms is -from organizations to jurisdictions-duly deliberated and critically analyzed concerning their potentials and risks surrounding the approach. AI systems, especially algorithmic machine learning-based ones, can issue-based data screening, detecting patterns and anomalies that may reflect malicious actions of cyber-threats in a wide range [2,3]. AI-based cybersecurity solutions equipped with humans' cyber abilities have proven to be effective in fighting against malware and phishing and detecting unauthorized intrusion attempts more than that contributed to the height of digital infrastructure.…”
