Mobile phones are becoming increasingly sophisticated, enabling consumers to access more services and generate more data. However, the current PIN and password protection capabilities available on mobile phones are often misused resulting insufficient protection of the information stored within mobile phones. Image-based authentication (IBA) leverages the human ability to recognize graphics better than recalling a sequence of strings and results have shown increased pass-image memorability among users. In this paper, the performance results and user opinions of two IBA techniques, Picture Password and Awase-E, will be compared alongside PIN and password as control techniques. In summary, of the data on authentication speed and success rate were collected but results indicate that Awase-E is possibly a superior technique which is more preferred by users.
