If you’re disappointed with big data, you’re not paying attention. There has been a backlash lately against big data.
From O’Reilly Media to the New Yorker, from Nassim Taleb to Kate Crawford, everyone is treating big data like a piñata. Gartner has dropped it into the “trough of disillusionment.” I call B.S. on all of it. It might be provocative to call into question one of the hottest tech movements in generations, but it’s not really fair. Physical unclonable function. History[edit] Early references about systems that exploit the physical properties of disordered systems for authentication purposes date back to Bauder in 1983[1] and Simmons in 1984.[2][3] Naccache and Frémanteau provided an authentication scheme in 1992 for memory cards.[4] The terms POWF (physical one-way function) and PUF (physical unclonable function) were coined in 2001[5] and 2002,[6] the latter publication describing the first integrated PUF where unlike PUFs based on optics, the measurement circuitry and the PUF are integrated onto the same electrical circuit (and fabricated on silicon).
From 2010 onwards till 2013, PUF gained attention in the smartcard market as a promising way to provide “silicon fingerprints”, creating cryptographic keys that are unique to individual smartcards.[7][8] Concept[edit] PUFs depend on the uniqueness of their physical microstructure. This microstructure depends on random physical factors introduced during manufacturing.
