Professor Walter Arrighetti holds a Laurea in Electronics Engineering, a Ph.D. in Electromagnetism (multidisciplinary between mathematics, computer science and physics) and a PostDoc, all from University of Rome "La Sapienza", where he focused on high-performance computing (HPC) for field theories in fractal geometries. He is also a Certified Information Systems Security Professional (CISSP).
He joined Technicolor in 2008, where he specialized, with increasing responsibilities, in top-tier storage+computing infrastructure ―both on-premise and Cloud-based― for the post-production, VFX and localization of international full-feature films, mostly high-profilers from major film studios ― like The Hobbit trilogy, Iron Man 3, Harry Potter VII and Batman: DKR, just to name a few.
He was thus exposed to the onset and development of enterprise-grade technologies like SAN, Content Protection, 4K HDR HFR, SaaS/PaaS/IaaS, in the transition era from photochemical film to fully-digital, delocalized collaborative pipelines, for which he also holds 10 international/US Patents.
During 2014‒2017 he served as CTO for Frame by Frame Italia, that is now one of the leading postproduction boutiques in the country for theatrical and commercials, and was also the first Italian media-processing facility certified as NETFLIX Preferred Vendor.
Prof. Arrighetti currently works as digital transformation consultant for both for the Italian Government (AgID―Agency for Digital Italy, and Ministry of Internals), and for several Media & Entertainment companies, including standardization bodies which he cooperates in drafting new standards, like the Oscars®' ACES (Academy Color Encoding System) and SMPTE's Interoperable Master Format (IMF).
He specializes in Information Security (e.g. PKI-based electronic trust services), dematerialization/archival ICT technologies, and multimedia processing.
