The analysis of fingerprints for matching purposes generally requires the comparison

The analysis of fingerprints for matching purposes generally requires the comparison

of several features of the print pattern. These include patterns, which are aggregate characteristics of ridges, and minutia points, which are unique features found within the patterns.

The major Minutia features of fingerprint ridges are: ridge ending, bifurcation, and short

ridge (or dot). The ridge ending is the point at which a ridge terminates. Bifurcations are points at which a single ridge splits into two ridges. Short ridges (or dots) are ridges which are significantly shorter than the average ridge length on the fingerprint. Minutiae and patterns are very important in the analysis of fingerprints since no two fingers have been shown to be identical.

Facial Recognition : Techniques Traditional Some facial recognition algorithms identify facial

Facial Recognition : Techniques

Traditional
Some facial recognition algorithms identify facial features by extracting landmarks,

or features, from an image of the subject's face, for example, the relative position, size, and/or shape of the eyes, nose, cheekbones, and jaw. These features are then used to search for other images with matching features.
3-D Recognition
This technique uses 3D sensors to capture information about the shape of a face. This information is then used to identify distinctive features on the surface of a face, such as the contour of the eye sockets, nose, and chin.
One advantage of 3D facial recognition is that it is not affected by changes in lighting like other techniques. It can also identify a face from a range of viewing angles.
Skin Texture Analysis
Another emerging trend uses the visual details of the skin, as captured in standard digital or scanned images. This technique, called skin texture analysis, turns the unique lines, patterns, and spots apparent in a person’s skin into a mathematical space. Increases performance by 20 to 25 percent.

Retina Scanning

Analysis of layer of blood vessels at the back of

the eye
Typical system: low-intensity light source and an optical coupler; the user needs to remove glasses, keep the eye focused on the light, 15 seconds
Applications:
High-end security: military etc.
Used for authentication and identification purposes
Слайд 15

The human retina is a thin tissue composed of neural cells

The human retina is a thin tissue composed of neural cells that is located in the posterior

portion of the eye. Because of the complex structure of the capillaries that supply the retina with blood, each person's retina is unique. The network of blood vessels in the retina is so complex that even identical twins do not share a similar pattern.
A biometric identifier known as a retinal scan is used to map the unique patterns of a person's retina. The blood vessels within the retina absorb light more readily than the surrounding tissue and are easily identified with appropriate lighting. A retinal scan is performed by casting an unperceived beam of low-energy infrared light into a person’s eye as they look through the scanner's eyepiece. This beam of light traces a standardized path on the retina. Because retinal blood vessels are more absorbent of this light than the rest of the eye, the amount of reflection varies during the scan. The pattern of variations is converted to computer code and stored in a database.

Customer authentication for service calls
Слайд 18

Verification versus Identification There are two major applications of speaker recognition

Verification versus Identification
There are two major applications of speaker recognition technologies and methodologies.

If the speaker claims to be of a certain identity and the voice is used to verify this claim, this is called verification or authentication. On the other hand, identification is the task of determining an unknown speaker's identity. In a sense speaker verification is a 1:1 match where one speaker's voice is matched to one template (also called a "voice print" or "voice model") whereas speaker identification is a 1:N match where the voice is compared against N templates.
Variants of Speaker Recognition
Each speaker recognition system has two phases: Enrollment and verification. During enrollment, the speaker's voice is recorded and typically a number of features are extracted to form a voice print, template, or model. In the verification phase, a speech sample or "utterance" is compared against a previously created voice print. For identification systems, the utterance is compared against multiple voice prints in order to determine the best match(es) while verification systems compare an utterance against a single voice print. Because of the process involved, verification is faster than identification.

Signature Recognition

Signature recognition is a behavioural biometric. It can be operated in two

different ways:
Static: In this mode, users write their signature on paper, digitize it through an optical scanner or a camera, and the biometric system recognizes the signature analyzing its shape. This group is also known as “off-line”.
Dynamic: In this mode, users write their signature in a digitizing tablet, which acquires the signature in real time. Another possibility is the acquisition by means of stylus-operated PDAs. Dynamic recognition is also known as “on-line”.
Applications
Access to documents
Execution of contracts
Banking services

The information gathered from The BITE project is helpful to understand

the scope of how employees view biometric technology and their concerns of ethics and privacy.
99.51% surveyed feel the general public is not clearly or poorly informed of biometrics
82.09% feel that biometrics can potentially used to discriminate against ethnic/cultural/racial/religious groups
86.26% feel biometrics should not be permitted to use information to create its own profile of the individual’s habits and activities
