Abstract: The use of a magnetic particle based “PUF” (Physically Unclonable Function) disk, when read by magnetic sensor(s), as a positional encoder is described. It is often necessary to include a linear or rotary encoder within a device for tracking motor movements, or to enable a closed-loop control algorithm on the motor system. These randomly dispersed magnetic particle disks can be used as a positional encoder, where the speed of movement and the direction of movement may be monitored.

Abstract: Unique Physical Unclonable (PUF) function objects may be created by molding or extruding specialized particles creating a measurable physical characteristic over a surface. The magnetized particles form a unique measurable magnetic “fingerprint” based on the random size, position, polar rotation, magnetization level, particle density, etc., of the particles. PUF objects may also vary in other physical characteristics by having a mixture of magnetic, conductive (magnetic or nonmagnetic), optically reflective or shaped, varied densities or mechanical properties resulting in random reflection, diffusion, or absorption of acoustical energy particles in a matrix or binder. The present invention envisions sensing any of the characteristics.

Abstract: Magnetic PUFs (Physical Unclonable Function) may utilizes a single 3-axis Hall-effect sensor for enrollment. When a PUF is manufactured, a Hall-effect sensor is used to model the PUF disk and store that data where it may be accessed. This process is called “enrollment.” This invention improves upon the PUF implementation by introducing controlled variability into the enrollment, the reading of the PUF data from the Hall-effect sensors (the number and position of read sensors), the sampling method of the read sensor(s), and the processing of the PUF data.

Abstract: A physical unclonable function (“PUF”) object can be used to encode the geography or region in which device to which the PUF is attached may operate. Disclosed are two potential ways to regionalize a device using a PUF disk: placing the magnetic sensor at a different radius depending on the region or geography intended for sale; and altering the magnetic structure of the disk to magnetically encode the region into the sensor data.

Abstract: Unique physical unclonable function objects are created by molding pre-magnetized or post-magnetized particles into a resin. The particles form a unique physical “fingerprint” based on the random particle size, position, polar rotation, magnetization level, particle density, etc. This invention addresses devices for accurately measuring the physical fingerprint of a PUF, specifically including the X, Y, & Z components of the magnetic field at enough discrete points on the PUF to allow a confident recognition of the identification. A structural element to which a PUF tag is affixed is described that may be used to scan the PUF tag with a smartphone magnetometer by swiping the structural element along the side of the phone and controlling the position of the PUF tag with guides.

Abstract: A mobile computing device hosts an operating system and mobile applications. A provisioning application communicates with a secure element and near field communication (NFC) subsystem. It causes display of an interface for users to enter personal attributes for storage in the secure element. Users discriminately select items from their personal attributes for transmission to a third party recipient so only attributes relative to the third party are sent. Software, interfaces, methods, and apparatus typify the embodiments.
