Abstract: A method is provided for authenticating a device in a system having a blockchain. The method includes executing a one-side authentication of the device. The results of the one-side authentication are submitted to the blockchain at a first blockchain node of a plurality of blockchain nodes. The one-side authentication is later verified at a second blockchain node of the plurality of blockchain nodes. The device may be a tag in a radio frequency identification (RFID) system.

Abstract: Various embodiments relate to a method of producing a machine learning model with a fingerprint that maps an input value to an output label, including: selecting a set of extra input values, wherein the set of extra input values does not intersect with a set of training labeled input values for the machine learning model; selecting a first set of artificially encoded output label values corresponding to each of the extra input values in the set of extra input values, wherein the first set of artificially encoded output label values are selected to indicate the fingerprint of a first machine learning model; and training the machine learning model using a combination of the extra input values with associated first set of artificially encoded output values and the set of training labeled input values to produce the first learning model with the fingerprint.

Abstract: A portion of a reprogrammable storage device is used to implement permanent data storage. The storage device includes a plurality of electrically erasable memory elements and a controller. The plurality of electrically erasable memory elements are configured to store data. Each memory element is programmable a number of write cycles before reaching a write failure state. The controller is coupled to the plurality of memory elements. The controller includes a receiver and a write engine. The receiver receives an instruction to drive a selected memory element to the write failure state. The write engine repeatedly writes a data value, in a plurality of write operations, to the selected memory element until the write failure state of the selected memory element is established.
