Researchers have warned people to use patterns to unlock you phones.In new study its much easier to remember the pattern then a PIN code, but you can protect yourself by switching from pattern lock code to PIN code and increase the PIN code length from 5 to 6 digits.

The researchers additionally thought of single and multiple views for the offender and 2 totally different hand positions for the victim – single-handed thumb input and two-handed index-finger input.

The study found that four-length patterns with visible lines were way easier to crack, as a results of shoulder water sport than the other sort of unlocking authentication they tested.

“We realize that PINs square measure the foremost secure to shoulder water sport attacks, and whereas each varieties of pattern input square measure poor, patterns while not lines provides larger security,” the researchers, from us academy and therefore the University of Maryland, said.

“The length of the input conjointly has associate degree impact; longer authentication is safer to shoulder water sport. in addition, if the assailant has multiple-views of the authentication, the attacker’s performance is greatly improved.”

In tests, 10.8 per cent of six-digit PINs were cracked when one observation. This figure rose to twenty six.5 per cent when 2 observations. 64.2 per cent of six-length patterns with tracing lines, meanwhile, were cracked when one observation. This rose to seventy nine.9 per cent after two observations.35.3 per cent of six-length patterns while not tracing lines were cracked when one viewing, rising to fifty two.1 per cent when 2 viewings.

“Shorter patterns were even more vulnerable,” the researchers, UN agency added that even people who use fingerprint or face-scanning technology to unlock their phones ought to be cautious of their findings.

“Biometrics could be a promising advancement in mobile authentication, however they’ll be thought of a re-authenticate or a secondary-authentication device as a user continues to be needed to own a PIN or pattern that they enter rather ofttimes as a result of environmental impacts (e.g., wet hands),”.

“There are best-known to be high false negatives rates related to life science. Further, users with life science typically opt for weaker PINs as compared to those while not, suggesting that the classical unlock authentication remains a vital attack vector going forward.”

A separate study revealed earlier this year found that the bulk of lock patterns may be cracked inside 5 tries.
