Biometric systems have become increasingly popular for user authentication andidentification across various domains, including smartphones, laptops, financial services,healthcare, and security. These systems offer enhanced security and quickaccess to data, aiming to address the challenges associated with passwords and pins.However, achieving a method that provides a 100% guarantee in all fields and for alldevices remains a challenge. To explore user perceptions on the acceptance of biometricsystems, an online survey was conducted with 99 participants from diversebackgrounds, education levels, ages, and countries. The survey focused on understandingusers’ acceptance of biometric systems based on their experiences and perspectives.Additionally, it aimed to investigate whether demographic factors, suchas age, education, and background, influence user acceptance. The study also comparedthe preferred authentication technique among users with findings from previousstudies. The survey results supported previous research, showing that fingerprinttechnology is the most recommended and preferred method for user authentication,followed by facial recognition. This study sheds light on the growing adoption ofbiometric systems to overcome password-related issues and provides valuable insightsinto user preferences for authentication and identification methods.

An era in which transactions and communication are quick and easy owing to fast-growing IT technology has commenced nowadays. Because of the extensive use of IT and its wide distribution, it is easy to access private information. Implementing more stringent computer security processes is vital to shielding this data from unlawful penetration, a never-ending battle. Data and service integrity, availability, and confidentiality are the three pillars upon which computer security stands. Password authentication is the key defense mechanism used among the systems battling security loopholes. This research selected a systematic literature review (SLR) to collect up-to-date data on different password security authentication mechanisms. A detailed review of the previous work isdone to gather all existing authentication techniques from the current literature and compare and select them for use in different settings. The result revealed the usages, benefits, and drawbacks of discovered password security and authentication methods. In the end, a framework is proposed to enhance the security of password systems.

No / Security is a function of the trust that is associated with the active variables in a system. Thus, the human factor being the most critical element in security systems, the security perimeter could be defined in relation to the human trust level. Trust level could be measured via positive identification of the person/device on the other side of the interaction medium, using various authentication schemes; location-based being one of the latest. As for the location-based services, the identity of a customer remains hazy as long as his location is unknown; he virtually remains a ghost in the air, with implications on trust. This paper reviews the various location-based authentication techniques with a focus on the role that GPS could play in optimising this authentication approach. It advocates the urgent need to make all transmission devices GPS-compliant as a way forward, despite the privacy issues that might arise.
