BIOMETRICS SECURITY

Biometrics includes the study ofmethods for uniquely recognizinghumans based upon one or more

intrinsic physical or behavioral traitssuch as eye iris, voice tones, palmprint, face outline...

Biometric Technologies fill the role ofanalyzing and measuring uniquebiological properties in order to

produce unique identifications which is

Explanation of the terms

Face Detection: locating the face inthe photo or video and removingunnecessary details on the

background.

Feature Extraction: extracting facialcharacteristics needed for recognition.

Feature Match: comparing scannedinformation with database to decide ifitmatches some users face. If the

face matched, the ID of the

Influences of variedlighting

As introduced, the basis algorithmshave not worked well when there arechanges in lighting .

In the latest performancemeasurement report of facerecognition algorithms, the result was

only good when the lighting did notchange.

Influences of imagecapturing devices

The algorithms applied to testedenvironments where the database inuse was limited and the images had

high resolutions while the majority ofcameras produced by the threes havelow resolution (the highest is only 1.3

Megapixel, and the lowest is 0.3Megapixel).


14/15

Influences of ImageProcessing

One special point we found out whenstudying those algorithms is that all ofthem work with images that have

already been digitalized and gonethrough image Processing.

Consequently, we think that this is the

weakest security spot in facerecognition systems generally andaccess control system of the three

vendors particularly.
