DETAIL ANALYSIS OF IRIS SCANNING

Iris scan takes about 30sec & 2sec for

verificationA camera located at about 3 feet focuses on &scans iris from one sideThis scan is converted into a template

Only phase information is used for recognizingiris as amplitude information is depends onextraneous factors

ADVANTAGES OF IRIS SCANNING

Iris pattern posses high degree of

randomness,variability & uniquenessPatterns are apparently stable throughout lifeEncoding & decision making are tractableImage analysis & encoding time : 1secSearch period : 100000 iris codes/sec

DISADVANTAGES OF IRIS SCANNING

Small target (1cm) to acquire from a distance(1m)Located behind a curved, wet, reflecting surfaceObscured by eyelashes,lenses,reflections

Partially occluded by eyelids, often droppingIllumination should not be visible or bright
