Abstract [sv]

Under de senaste åren har den mobila tekniken i stort sett helt gått över till smartphones. Smartphones är i princip mer datorer än telefoner, som vi alltid bär med oss och som innehåller allt mer känslig information. Detta medför att kraven på säkerheten kring enheten ökar. Detta arbete undersöker om det är möjligt att finna en ny metod att låta användaren autentisera sig på, som är säkrare än de som är vedertagna idag, men samtidigt har liknande nivå av användbarhet. Vår idé, som vi arbetar med under namnet Colour a Symbol, baseras på att kombinera symboler och färger i par. För att utveckla idén skapade vi en funktionell prototyp, som sedan utvärderadesmed hjälp av en mindre testgrupp. Empirin visar på att Colour a Symbol har en god användbarhet, om än något för lång inloggningstid. Idéer för att förbättra inloggningstiden presenteras. Teoretiskt sett så är Colour a Symbol säkrare än exempelvis pinkod, men testgruppen var inte tillräckligt stor för att kunna bedöma den praktiska lösenordsrymden. Utformning av symboltema påverkar även förmodligen i hög grad den praktiska lösenordsrymden. Vår slutsats är att idén har en klar potential, men att det behövs ytterligare studier för att finslipa den.

Abstract [en]

During the past years mobile technology has moved almost entirely to smartphones. Smartphones are in essence more computers than phones, which we always carry with us and that contain ever more sensitive information. This requires that the level of security around the device increases. This study strives to find a new method of authenticating users, that is more secure than those that are established today, but at the same time has a similar level of usability. Our idea, which we work with under the name Colour a Symbol, is based upon making combinations of symbols and colours in pairs. In order to develop the idea we created a functional prototype, that was evaluated by a smaller test group. The empirical data implies that Colour a Symbol has good usability, if only a little too long login time. Ideas as to shorten the login time are suggested. Theoretically, Colour a Symbol is more secure than for an example pincode, but the test group was not large enough to estimate the practical password space. Design of the symbol theme probably also affects the practical password space to a high degree. Our conclusion is that the idea has clear potential, but that further studies are needed to fine-tune it.
