DESCRIPTION:KYC sits on a paradox: regulators demand strong identity proofs
 \, but every byte of identity data a service stores becomes a permanent br
 each surface. The traditional answer: collect documents\, run checks\, fil
 e them away\, turns every KYC provider into a high-value target and every 
 user into a permanent disclosure.\n\nThis talk walks through an alternativ
 e pipeline now running in zkKYC field\, where a stack of well-chosen crypt
 ographic primitives composes into a system that proves claims about a user
 : their passport is valid\, they are over 18\, they are the same person wh
 o registered last month\, without the server ever seeing their identity da
 ta. The journey spans device-bound keys\, encrypted identity storage\, gov
 ernment-signed document chains\, biometric commitments\, zero-knowledge pr
 oofs\, and authenticated claim delivery but the goal throughout is to show
  how these pieces fit together\, not to dwell on any single one.\n\nDesign
 ed for engineers and product folks alike\, the talk explains each primitiv
 e at a high level (no math)\, focuses on system design and uses architectu
 re diagrams throughout. By the end\, you will follow how the same passport
  scan that validates a user's age also produces a server-blind\, unlinkabl
 e proof — and why this is starting to look like the only sustainable way
  to do identity at scale.\n\nTakeaways: a vocabulary for evaluating privac
 y-preserving identity systems\, a concrete reference architecture\, and an
  honest list of open problems (biometric revocation\, post-quantum SNARKs\
 , deduplication without linkability) this design has not yet solved.
