This measures how close a biometric reading is to a prerecorded template

The question above has multiple choices;

a)      Hamming distance

b)      Match percentage

c)       Legacy amount 100.

d)      PDA reading

The answer is a) Hamming distance

Biometric authentications like other technologies are vulnerable to attacks such as spoofing and transmission. Binary template representations in recent research provide significant improvements in efficiency without compromising data accuracy for biometric modalities like iris, fingerprints, and palm prints.

Any binary biometric representation that uses hamming distance and converts it into a privacy preserving secure protocol comparison provides template protection.

the correct option is (d) vin label

vin stands for vehicle information number. this is a thin metallic plate attached to the engine of the vehicle and it includes all the important information which are related to the vehicle. it also provides the information whether the vehicle has been stolen or not because the replacement and alternation of vin number creates difference in the exact number printed on the vin and carved on the engine.
