Do you prefer to unlock your smartphone with four standard numbers or expressive symbols? Would it be easier and more fun for example to remember "🐱💦🎆🎌", or "1184"?
Smartphone users often use emoticons to express their moods and emotions in e-mail and text messages, and even there are those who communicate in full messages only with emoji. In 2015, a British company tried to use emoji rather than normal code in the bank's ATMs. But there was no formal study of their ease of use or safety compared to other methods, such as PINs.
To learn more, in the laboratory and in the real world, a team of researchers from the University of Technical University in Berlin, University of Ulm and University of Michigan, led by Lydia Kraus, developed EmojiAuth, a sign-in system based on emoticons for Android phones. How well do users understand their emoji? Can you be more secure, too? Or maybe it will be more fun?
Most smart phone users keep their screens locked and locked and need to open them several times a day. Many people use numerical codes, but research tells us that images are easier to memorize than numbers or letters. Numeric codes can also be made up of a few symbols: numbers from 0 to 9. Passwords can be created from a larger set of characters but typing them on smart phones is tricky. The use of emoticons, on the other hand, allows us to choose from more than 2,500 emoticons, which are more resistant to piracy and intrusion.
EmojiAuth is still under development, and once it is released, we will tell you the news.
