Description of Project ●Project is a continuation from last semester. ●Main objective of this project is usability studies to evaluate the acceptability and the ease-of-use of two or more biometric prototype systems. ●The evaluations were obtained through interviews and surveys. ●Conducted study, and analyzed the results. Recognition Technologies, Inc. will allow us to use their proprietary facial and speaker verification systems for these studies.

 How often do you access a website that requires a login?  How valuable and sensitive is the information that will be stored in this website?  Do you really want to remember yet another password (“YAP”) so should I use an existing one?  How quickly do you want to do any particular transaction on a website, so do I even care what my password is right now?

What is Multimodal Biometrics???? Biometrics refers to technologies that measure and analyze human body characteristics. Multimodal biometric authentication merge two or more of these factors for improved security. In this project, we will be experimenting with this type of authentication system designed by Dr. Beigi of Recognition Technologies, Inc.

How is voice recognition used in biometrics? Voice recognition technology utilizes the distinctive aspects of the voice to verify the identity of individuals. Can utilize any audio capture device – including phones and PC mics Dr. Beigi’s technology only uses about 8 secs of a spoken sentence (during enrollment the system records 60 secs of audio)

How does facial recognition work Recognition is performed by frontal portrait face detection and recognition, to be used as a biometric. Facial recognition (or face recognition) is a type of biometric software application that can identify a specific individual in a digital image by analyzing and comparing patterns. Facial recognition systems based on faceprints can quickly and accurately identify target individuals when the conditions are favorable. However, if the subject’s face is partially obscured or in profile rather than facing forward, or if the light is insufficient, the software is less reliable.

Product Assessment & Features

The Surveyors  Our Target was 200 responses  We sent the survey out to 400+ friends and family as well as posted on social media  It was also sent to fellow capstone students and DPS students  We were only able to get 104 responses back (which was more than double from last year)

Our Findings This Bar graph displays result when respondents were asked how convenient the audio and visual biometric verification system to be. The majority of the survey pool found the technology to be somewhat convenient (47%) followed by extremely convenient (30%) and neutral (17%). Based on the overview and evaluation of this system, we find that biometric verification is viewed to be convenient by the public. This Bar graph displays how secure the audio and visual biometric verification appeared to the surveyors. The majority found it to be secure with 49% followed by 32% rating it as being very secure. This is often the main topic when it comes to how secure this type of security can be and what it can be trusted with. By means of our audience showing that most of them believe it to be secure, it shows how willing society is in accepting and feeling comfortable with biometric verification.

Our Findings cont. When users were questioned on the perceived delay time between the biometric verification and the system granting access to the user, 56% did not feel there was a significant delay in the time, where the system was being a hindrance. However, 44% of the surveyors did find that there was a significant lag between the two sequences. During testing, it was determined that access was either granted or denied rather quickly but the actual perceived delay was caused by the mechanical door lock solenoid. This Bar graph displays the question of how much delay would be acceptable for a user to still adopt a biometric system. This chart shows surveyors would be ok having a delayed response for higher security. Most of the surveyors preferred lesser authentication times, however, for sensitive information such as medical records, border crossing and banking information some surveyors did prefer a slower and more robust authentication system.

Our Findings cont. The question was posed as to whether society was ready for the adoption of a biometric system. In the previous semester’s survey, the respondents were split equally 50/50 on this matter but interestingly, this year, acceptance grew with 68% of the users willing to switch from a user- password combination to a biometric authentication system The question was asked to the survey pool whether a biometric system was acceptable for use with children at home, school, home and school or not at all. The majority (56%) of respondents stated it was acceptable at home and school. 22% determined it was not an acceptable method for use with children.

Lastly The respondents also agreed that a biometric authentication system with or without a pin code was more desirable than the use of a username/password or no security in place as all with regards to ease-of-use, convenience and security

Final Thoughts and Interesting tidbits ●Threshold ○Can be raised and lowered ■At only 20% Jimmy and Manny were able to use each others pin/facial/audio ■At 45% they were not able to spoof the system ●Spoofing the System ○Not able to use recorded audio/video ○Mustache and other add-ons did throw the system off ○Background music and audio was not an issue during authentication

WHAT IS THE FUTURE OF BIOMETRICS The user is the password 68% of the surveyors felt we are ready to take on Biometrics – this is double the positive response from last semester. There are studies that suggests the top four biometrics preferences are due to the current technologies on cell phones, tablets and laptops which already integrates biometrics security technologies. Border crossing and international travel can be revolutionized by this technology
