This paper focuses on data collection for keystroke biometric authentication studies. An experiment was performed on biometric keystroke characteristics of a person using a mobile device (nexus 5). Two types of input were collected--text and numeric entry from 10 different users. The purpose of the experiment was find ways to improve biometric security classification systems for future use, such as for the authentication of online test taking students and computer users. Included in the paper are brief literary reviews, followed by the methodology and results of the experiments that were carried out.
