Dangers of the ‘V’

Do you often make the V sign(手势)when taking photos？You might want to do so less often from now on.

Experts(专家)say that it is possible to use the V sign to copy(复制)someone's fingerprints(指纹)．Someone could take your photo，zoom in (放大) on your fingers，and then use AI technology(人工智能技术)to copy your prints.

Does that mean you should not make the V sign in photos anymore？Not really.The fingerprints in your photos must be clear enough to copy.If the photo is taken from 1.5 meters or less away，it is possible to copy your prints.But if the photo is taken from over 3 meters away，your prints won't be clear enough to copy.The photos we put online are usually not clear enough to copy.But still，you should be careful.
