Towards a User Identification Framework for Mobile Devices

Due to the high percentage of mobile devices thefts and the financial loss that it causes, this paper aims to develop an inexpensive framework to identify a user to his/her mobile device. In case the user is not successfully identified the mobile devices´ manager blocks the device completely, avoiding use of any service, including calls, browsing the Internet, sending SMS and accessing personal data, such as contacts, last calls made and received, among others. Experiments using PDAs are presented to demonstrate the feasibility of this project.
