The current security on mobile phones is often limited to the Personal Identification Number (PIN) which is a secret-knowledge technique. Studies highlighted the drawbacks of such a method. The technologies on such devices are likely to evolve fast. As an example, a lot of handsets enable online banking or shopping nowadays, which can involve the storage or processing of sensitive data. The security on such devices should be effective to prevent impostors to use them. This study proposes an enhanced technique for authentication on Smartphone using keystroke analysis. Results of a practical evaluation are presented based upon the entry of a password which can be either number or character-based. The findings reveal the technique employed is not yet ready to be deployed on the market as the performance rates are relatively poor. However, it suggests that this biometric technique could be utilised on a mobile device as the processing requirements of the algorithms used are low. Furthermore, this study collected the participants’ thoughts and reactions about the system which were interesting to discuss.
