Κλειδώνετε το Android σας με κάποιο σχέδιο πάνω στο πληκτρολόγιο; Αναφέρουμε συχνά τους codeς πρόσβασης, επισημαίνοντας την αναγκαιότητα χρήσης κωδικών μεγάλων σε μέγεθος που περιέχουν ασυνήθιστους χαρακτήρες. Κωδικοί πρόσβασης του τύπου “12345” ή “password”, είναι εύκολα προβλέψιμοι και, συνεπώς, δεν σας προστατεύουν.
Αποδεικνύεται όμως ότι και το χαρακτηριστικό ασφαλείας του Android που δεν uses passwords but the "painting" of a shape on the device's keys is just as predictable as common passwords.
Marte Løge, a Norwegian University's Science and Technology graduate, analyzed 4.000's plans for this Android lock and found that 77% of these were predictable starting from one of the four corners.
As Ars Technica says, the researcher also found that 44% of participants started their plans from the upper left corner. Loge presented her findings in detail at the PasswordsCon conference held in Las Vegas.
As it emerged from study of the researcher the virtual patterns created by the participants and by extension most people are four nodes. Patterns with eight knots were less popular.
Interestingly, about 10% of motifs using nodes connect letters like M or N, and usually represent another important or a child's user.
Loge, although her research was the first to deal with this specific Android lock, proved that the best practice for locking it is not to start from a corner.
For better results you can use intersections and as many nodes as possible.
