Cloud-based user authentication with geo-temporal queries on smartphones

Content Provider ACM Digital Library
Author Choi, Brian J. Choi, Seonho Sun, Kun
Abstract Smartphones are becoming more and more important in our daily life and carrying massive private data. Without a user authentication mechanism, an adversary may easily access all the sensitive information, such as contacts, messages, photos, credit card information and passwords. Therefore, a number of authentication techniques have been proposed and developed for mobile devices. Some of the most commonly used techniques include conventional password based scheme, pattern-based scheme, physiological biometric based techniques, etc. In this paper we focus on designing and developing an authentication scheme utilizing a series of geo-temporal queries for user authentication on smart phones. The basic idea is to use past knowledge on geographic and temporal (or geo-temporal) contextual perspectives to authenticate the user who wants to unlock the smart phone. On Android 4.3, we build a prototype App, which provides user authentication to unlock a Samsung Galaxy S4 smartphone with low power consumption.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
