![]() “Even if they can observe you, the advantage of gesture is it would take them time and practice to replicate it,” he says. Nasir Memon, a professor of computer science and engineering at New York University who has conducted similar research in the lab, says that while making a password-entry system more tolerant of variations in the shape you swipe opens up avenues for attack, the subtleness of the speed and pressure when using your hand to enter a shape also makes it hard for a hacker to imitate. One possible way to limit bad guys from breaking such passwords may lie with the threshold that must be set for how precisely a person needs to swipe his gesture on the screen to get into a given account-in real-world applications, Lindqvist says, you could tweak these thresholds based on how secure you want an account to be (although, presumably, that could also make it frustrating to users with sausage fingers). Typing Fingers uses a completely new approach to teach the efficient touch-typing (ten-fingers) system. What’s not yet clear is whether it could become easier for a hacker to crack gesture-based passwords if they were more commonly used. Since a lot of these errors happened soon after they made their passwords, and they dropped off over time, researchers think it indicates that getting accustomed to these kinds of passwords will take time.īut Lindqvist says the gestures can be more secure than text passwords, since they can be more randomized, and it’s easy to generate tons of text-based passwords with a computer that can be used to hack into people’s online accounts. ![]() The gesture-password group did make almost twice as many errors in inputting their passwords, however. Typing Tournament is the complete 10-finger typing course for ages 6 to adult. You can measure your typing skills, improve your typing speed and compare your results with your friends. This time, they wanted to see what would happen when people actually tried them on their phones while going about their days as usual, so they had a group of 91 study participants use their own smartphones over two weeks with an app that occasionally prompted them to log into fake accounts (two different ones during the first week, and six during the second week). Typing Test - 10fastfingers offers a free online Typing Speed Test Game in multiple languages. The research comes two years after Lindqvist and his colleagues started investigating the use of gestures for authentication on tablet touch screens in the lab. Free-form passwords you draw with your fingers can be faster than typing passwords and as easy to remember, say researchers at Rutgers University and Aalto University. He co-authored a paper detailing the work that will be presented in May at the ACM-CHI computer-human interaction conference in San Jose, California. ![]() “These gestures really present an alternative to smartphone authentication because they are fast to create and also fast to use,” says Janne Lindqvist, an assistant professor of electrical and computer engineering at Rutgers. ![]()
