For a second year in a row, senior computer science major John Harakas, of Wilton, presented at Eastern Connecticut State University's CREATE (Celebrating Research Excellence and Artistic Talent at Eastern) Conference on April 21.

CREATE is the university's academic year-end showcase, where students of all majors presented professional posters, live music, dance performances, artwork, photography, documentaries and panel discussions.

At the second annual conference, Harakas gave an oral presentation called "Analyzing Keyboard Vibrations Recorded by Mobile Devices.”

"The explosion of affordable computing has packed mobile devices with sensors that observe our physical environment,” said Harakas, “with each subsequent generation of devices becoming increasingly accurate.”

"One field of computer security focuses on side-channels,” he said, “in which information leaked from the physical surroundings can be used as an attack vector.”

Harakas said this research “explored methods of keystroke recovery using an Android device accelerometer with a sampling rate of 100Hz” and “the low sampling rate posed a tremendous challenge in determining if the recorded vibrations contained enough information to uniquely identify keystrokes."

During the one-day conference, the student center crawled with artistic and scholarly activity. Students in professional attire addressed their peers, faculty and family. In the cafe, ensembles performed; in the theatre, student-produced documentaries were shown; in the Betty R. Tipton Room, aisles of posters depicting scientific research were displayed; across the hall, a gallery-worth of paintings lined the walls; and on the ground floor, panel discussions and oral presentations about the humanities took place.

His presentation was one of approximately 250 student presentations, exhibits and demonstrations featured at this year’s conference, attended by parents, friends, alumni, corporate representatives, faculty and staff.
