Abstract

A novel system and method for accessing data stored in a secure or tamperproof storage device in a wireless communication device is provided. The wireless communication device may include a biometric sensor for capturing a biometric sample of the user. The captured biometric sample may be compared to known biometric samples of users stored in a memory device of the wireless communication device. If the captured biometric sample matches one of the known biometric samples, the user is allowed access to the tamperproof storage device for a preset amount of time. The user may delete existing data, add new data, modify existing data or view existing data stored in the tamperproof storage device.
