“Problems with Current Security Systems” Primarily based on passwords or ID/swipe cards May be forgotten or lost Can easily be stolen by thief or hacker Not very cost efficient in long run

Statistics on Passwords Case Study: Telesis Community Credit Union Manages $1.2 billion in assets The vice president lead a team to run a network password cracker With in 30 seconds they identified 80% of most people passwords They then told employees to change their passwords and comply with password policies They were still able to identify 70% of the employees passwords http://www.computerworld.com/article/2556096/security0/biom etrics--getting-back-to-business.html

“Possible Solution” Biometric Sensing Better security Offers convenience Easy and safe to use Available for many applications More affordable than ever

“The Concept of Biometric Sensing” Derived from the Greek words bio, meaning life, and metric, meaning measure. Identify a persons physical and behavioral characteristics A transducer that changes the trait into a electronic signal Traits such as fingerprints, iris, face, voice, etc. Requires one type of sensor

Sensor measures or reads light, temperature , speed, electrical capacity and other energies to obtain these readings A few applications: HD cameras for facial recognition or a microphone for voice capture Some even designed to scan vein patterns

Types of Biometric Sensors Physiological Biometrics Face Fingerprint Hand Iris Scanning Vein Behavioral Biometrics Keystroke Signature Voice

Face: Capturing data for nodal points and the resulting data can be stored as a face print. Fingerprint: Records its features like arches, whorls and loops along with the outline of edges, minutiae and furrows. Hand: Examines palm-print, hand geometry or hand shape, finger-knuckle print, hand veins, etc. Iris Scanning: Based on single patterns in the region of ring shaped surrounding the pupil. Vein: Identifies the pattern of blood vessels Keystroke: Describes exactly when each key was pressed and released as a person is typing. Signature: Measure the pressure applied, stroke order and the speed. Voice: Properties – nasal tone, fundamental frequency, inflection, cadence.

Fingerprint Semiconductor sensors: prone to ESD Pros Cons Most commonly used Semiconductor sensors: low cost Optic sensors: high degree of stability and reliability Ultrasound sensors: precise and fraud-free Semiconductor sensors: prone to ESD Optic sensors: larger in size Ultrasound sensors: expensive to implement

Face Recognition Facial reconstruction surgery Pros Cons No contact needed, just picture or video Accurate and fast results Reliable matching Considered most accurate technology available today Facial reconstruction surgery Some businesses may not have video systems

Iris Scanning More individual characteristics than a fingerprint Pros Cons More individual characteristics than a fingerprint Almost 100% accurate Face scanners are not yet able to be as accurate as they should be Things such as contacts, tears, longer eyelashes or dark eyes can sometimes throw off the machine

Other Information Fingerprint Use a CMOS image sensor or CCD Solid state sensors work on transducer technology

“Current Biometric Technology” BIO-key SideSwipe a swipe fingerprint reader that operates on any Window device with a USB port Microsoft's new Biometric sign-in feature. Only scanner devices in the market to pass Microsoft’s security testing qualification process

NEXT Biometrics EcoID USB fingerprint reader Portable and small fingerprint reader Active thermal sensor from NEXT Biometrics Compatible with Android and Windows NEXT Biometrics On April 26th 2016 they launched the first fully flexible fingerprint sensor for smart cards NB-2023-S = Fingerprint are sensor module Its technology is tolerant against dirt, grease and varying environmental conditions. Large active area allowing intuitive user operation Application Examples: notebooks, tablets, time and attendance terminals, smart card readers

“Future Biometric Technology” The use of Biometrics in banks Biometrics in branch banking, internet/mobile banking, ATM’s Most likely remove the password and PIN system in banking Visa Europe Report

DNA recognition Earlobe Recognition It captures the unique features from the uncoded portion of the DNA sequence Finished image in known as the “Digital DNA Fingerprint” Earlobe Recognition Measuring the distances between the prominent landmarks of the ear Two specific techniques are being examined to create the Biometric Template PCA 3-D Analysis

Gait Recognition Study of ways people walk Known as Kinematics, study of motion Capture the features of a individuals stride such as angles lengths and speeds Two techniques Static shapes Dynamic shapes

Summary Current security systems are not reliable or efficient Biometric technology is superior Technology is advancing

Five Questions The different types of Biometric Sensing. Advantages and disadvantages of a couple types. Why companies are starting to transition into Biometric technology? How do these sensors obtain these readings? What does this technology offer that will prevent people from getting accounts stolen or hacked?
