Nonetheless, a video being shared broadly on WhatsApp and different social media networks warns folks in opposition to utilizing it.
The clip claims fraudsters can use the pictures to take high-quality copies of their fingerprints, which they then use to hack into their telephones and accounts to steal their cash and information.
However how well-founded are the claims?
Merely put, it is technically attainable however impossible in apply.
Hackers might in concept extract copies of our fingerprints from the selfies we put up on-line, however solely in very particular situations, based on Sarah Morris, professor of digital forensics on the College of Southampton.

“With most telephones, getting that degree of decision from holding your hand up once you’re fairly faraway from the digital camera goes to be actually, actually tough,” she added.
Frank Breitinger, affiliate professor of digital forensic science and investigation on the College of Lausanne, got here to an analogous conclusion.
“You will get delicate data from photos which can be of fine high quality however in any other case it is arduous,” he stated. “Even you probably have it, reusing this information is even more durable.”
He famous many social media platforms additionally cut back the picture and video high quality after they log on, which acts as a further defend that may assist cease our information from being stolen.

Biometric information is normally saved regionally, resembling in your telephone, so hackers would usually want entry to the bodily machine as nicely to realize entry.
“Even you probably have this fingerprint, it isn’t that you simply simply take this image and submit it to a financial institution,” stated Breitinger. “There’s nonetheless much more that must be completed.”
“Let’s assume you wish to hack into my telephone which is protected with my fingerpint: You continue to want my telephone,” he added, explaining that hackers would want to bodily replicate the picture into one thing that may be positioned on their finger.
“Most sensors are adequate to detect if one thing is useless,” he stated.
To apply good cybersecurity, specialists counsel being conscious of the backgrounds and data you would possibly by accident share in your photos.
