An action-based authentication scheme for children Jan Edson S. Garcia. 2011. v, 31 leaves col. ill. + 1 CD-ROM (4 3/4 in.) Undergraduate student project (B.S. Computer Engineering)--University of the Philippines, Diliman. Recent trends show an increase in usage of mobile devices in business and home environments. With these devices getting more integrated into the lives of many people, great security concern arises. However, these devices continue to use passwords or Personal Identification Number (PIN) which are not suitable for touch screen displays they feature and are proven to be unsafe, tedious to use, and hard to recall. In this project, development of a new authentication scheme that will take advantage of touch technology was started using action-based state transition. This authentication scheme can be used with minimal reading skills. Using image manipulation instead of text input, we tried to address the usability and recall difficulties present with existing authentication schemes. Deployment with college students shows high level of interest among testers and approval of the testers for the scheme as a viable replacement for text-based passwords. Testing results with children show a 95.23% accuracy rate for the action-based scheme compared to text-based password's 85.71%, and an overall improvement in password input speed. Authentication.
