Survey and Analysis of Android Authentication Using App Locker

Android Smart phones have gained immense popularity over the years and is undoubtedly more popular than other operating system phones. Following the similar lines android wear was introduced. Steadily android wear is making its way into our daily lives. It helps keep track of the sleep you have, helps you reach fitness goals, keeps track of phone and helps users have easy authentication. Due to the usage of smart lock which enables phone to be unlocked as long as connected to the android wear, this leads to almost no security on both the ends as android wear before Android 5.0 has no lock. We aim to produce the existing authentication methods in android phones and wear and the threats that plague both kinds of devices. As authentication is one of the major building blocks of security, through research we aim at designing a system for android phones which will be able to protect the sensitive data on devices which will be at risk through smart lock using encryption techniques. In this proposed system, the user would be able to decide which applications are needed to be secured when he is using smart lock. This application will enable lock for those user chosen applications as soon as the smart phone device is connected to android wear and similarly disables the lock when connection is disabled between the devices and communication between devices is made secure using encryption algorithms. This application does not interfere with easy phone authentication which users demand but it makes sure data is protected and users are authenticated with the help of multiple authentication layering

Enhanced three-factor security protocol for consumer USB mass storage devices

The Universal Serial Bus (USB) is an extremely popular interface standard for computer peripheral connections and is widely used in consumer Mass Storage Devices (MSDs). While current consumer USB MSDs provide relatively high transmission speed and are convenient to carry, the use of USB MSDs has been prohibited in many commercial and everyday environments primarily due to security concerns. Security protocols have been previously proposed and a recent approach for the USB MSDs is to utilize multi-factor authentication. This paper proposes significant enhancements to the three-factor control protocol that now makes it secure under many types of attacks including the password guessing attack, the denial-of-service attack, and the replay attack. The proposed solution is presented with a rigorous security analysis and practical computational cost analysis to demonstrate the usefulness of this new security protocol for consumer USB MSDs

Secure and Privacy Enhanced Gait Authentication on Smart Phone

Smart environments established by the development of mobile technology have brought vast benefits to human being. However, authentication mechanisms on portable smart devices, particularly conventional biometric based approaches, still remain security and privacy concerns. These traditional systems are mostly based on pattern recognition and machine learning algorithms, wherein original biometric templates or extracted features are stored under unconcealed form for performing matching with a new biometric sample in the authentication phase. In this paper, we propose a novel gait based authentication using biometric cryptosystem to enhance the system security and user privacy on the smart phone. Extracted gait features are merely used to biometrically encrypt a cryptographic key which is acted as the authentication factor. Gait signals are acquired by using an inertial sensor named accelerometer in the mobile device and error correcting codes are adopted to deal with the natural variation of gait measurements. We evaluate our proposed system on a dataset consisting of gait samples of 34 volunteers. We achieved the lowest false acceptance rate (FAR) and false rejection rate (FRR) of 3.92% and 11.76%, respectively, in terms of key length of 50 bits
