Abstract In this paper, we present "MagiSign", a new user identification/authentication technique based on 3D magnetic signatures created in the space around a (mobile) device. The main idea is to influence magnetic (compass) sensor embedded in some mobile devices (e.g., iPhone 3GS, G1/2 Android) using a properly shaped magnet. The user draws 3D signatures in the 3D space around the device using a magnet (e.g., pen, rod, ring shaped). This is what we call as "3D Magnetic Signature". The temporal pattern of change in the magnetic field around the device is sensed and registered by the internally embedded magnetic sensor. For authentication/identification, new magnetic signature samples are compared with models created based on registered signatures. As the magnetic signature can be flexibly created in 3D space, it provides a wider choice for authentication. Unlike regular signatures, a hardcopy can not be easily generated resulting in higher security. "MagiSign" technique does not require expensive or complex hardware/algorithm, and does not imposemajor change in hardware or physical specifications of the device.It can be especially suitable for small mobile devices.
