In order to prevent any impersonation the invigilators checks candidates admit card and attendance sheet against the appearance of the candidate. However this is not a full proof system of checking impersonation.
The photograph of candidates are already available with us. There can be some online software which can match the candidate’s photograph against the candidate appearing for the examination.
A web camera may be paced at the entrance of the examination center which will first read the barcoded roll no. from admit card and than read the physical face of the candidate and match it against that centers registered candidates. The software will give match or mismatch or percentage result of matching.
