Behavioral biometrics tools identify users with keystroke dynamics, signature verification, voice recognition, and gesture recognition. These technologies compare a profile of the users against a database created with contextual information, including physiological, cognitive, and contextual traits. Institutions of higher education, governments, and financial institutions use these technologies to enhance the security of their cloud services. This, in turn, will create lucrative opportunities for industry leaders.
To address the behavioral biometrics market, a researcher at Rensselaer Polytechnic Institute has developed their own system for authenticating fonts based on keystrokes called "Digital Penmanship". Their tool only displays emoticons and/or pre-agreed upon fonts (i.e., Times New Roman Font 12 or Arial Bold 10) if a user passes a keystroke challenge. Whereas other proctoring tools only provide authentication certainty to proctors, the RPI system could give certainty to test takers that their online exam is not compromised by malware. As long as students see questions in the correct font, they can be assured their exam and connection is secure. By establishing a two-way data exchange, key loggers can gain greater trust from students.
