Latest Patents

One of Kim's latest patents is titled "Temperature-profiled device fingerprint generation and authentication from power-up states of static cells." This invention outlines a method, system, and computer program product for generating device fingerprints and authenticating devices. The process utilizes the initial states of internal storage cells after multiple power cycles at various device temperatures to create a unique device fingerprint. The fingerprint consists of pairs of expected values for each internal storage cell, along with the probability that each cell will assume its expected value. Notably, storage cells with expected values that vary across different temperatures may be excluded from the fingerprint. The authentication of a device is achieved through a similarity algorithm that compares the expected values from a known fingerprint with the power-up values from an unknown device, using the probability for each cell to compute a similarity measure.
