Peter Nicholas Biddle (born December 22, 1966) joined Microsoft in 1990. Biddle was one of the first authors to describe the darknet, a founder of SDMI, CPTWG, and TCPA, an early technical evangelist for DVD and DVR, the founding father of Microsoft’s Next-Generation Secure Computing Base (NGSCB, aka Palladium) initiative, and was responsible for starting Microsoft's Hypervisor development efforts.
In 1998, Biddle was the first person to ever publicly demonstrate real-time consumer DVR using an inexpensive MPEG2 HW encoder, at WinHEC. Biddle was the author of “The Biddle Diagram” on page 13 in the SDMI spec, which enabled the playback of “unknown” (e.g., potentially pirated) content on SDMI-compliant players, and was a vocal proponent within SDMI for the external validation of digital watermarking.
Biddle is a member of the Biddle family and is a descendant of Nicholas Biddle. He built and led the engineering team that shipped BitLocker Drive Encryption, a TPM-rooted disk encryption for Windows Vista, and he lives in Seattle.
