The system consists of a Java applet to collect raw keystroke data over the Internet, a feature extractor, and pattern classifiers to make identification or authentication decisions. Experiments on more than 100 participants investigated two input modes\u00e2\u20ac\u201dcopy and free-text\u00e2\u20ac\u201dand two keyboard types\u00e2\u20ac\u201ddesktop and laptop. The system can accurately identify or authenticate individuals if the same type of keyboard is used to produce the enrollment and questioned input samples. Longitudinal experiments quantified performance degradation over intervals of several weeks and two years. Additional experiments investigated the system\u00e2\u20ac\u2122s hierarchical model, parameter settings, assumptions, and sufficiency of enrollment samples and input-text length. Although evaluated on input texts up to 650 keystrokes, the authors found that input of 300 keystrokes, roughly four lines of text, is sufficient for the important applications described.<\/p>","DOI":"10.4018\/jisp.2010010103","type":"journal-article","created":{"date-parts":[[2010,4,19]],"date-time":"2010-04-19T23:03:07Z","timestamp":1271718187000},"page":"32-60","source":"Crossref","is-referenced-by-count":25,"title":["A Keystroke Biometric Systemfor Long-Text Input"],"prefix":"10.4018","volume":"4","author":[{"given":"Charles C.","family":"Tappert","sequence":"first","affiliation":[{"name":"Pace University, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sung-Hyuk","family":"Cha","sequence":"additional","affiliation":[{"name":"Pace University, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mary","family":"Villani","sequence":"additional","affiliation":[{"name":"Pace University, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert S.","family":"Zack","sequence":"additional","affiliation":[{"name":"Pace University, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2432","reference":[{"key":"jisp.2010010103-0","unstructured":"AdmitOne Security Inc.
