DESCRIPTION:Self-Sovereign Identity promises a different way of proving who
  we are online: instead of relying on a central identity provider\, users 
 can hold verifiable credentials and decide what information to disclose.\n
 But how much information do we really need to reveal to prove something ab
 out ourselves?\nIn many digital interactions\, a verifier does not need to
  know our full identity. It may only need to know whether we are over 18\,
  authorised to access a service\, hold a valid qualification\, or possess 
 a non-revoked credential.\nThis talk explores how selective disclosure\, Z
 ero-Knowledge Proofs and cryptographic accumulators can support a shift fr
 om identity disclosure to proof-based verification. Instead of transferrin
 g personal data and protecting it afterwards\, users can prove that a requ
 irement is satisfied without revealing the underlying information.\nUsing 
 scenarios inspired by the TRUSTED project\, we discuss data minimisation\,
  unlinkability\, credential validity and revocation. We also look beyond c
 ryptography itself: even privacy-preserving credentials can still enable c
 orrelation\, metadata leakage or unnecessary identification if the wider i
 dentity flow is poorly designed.\nThe key question is therefore not only 
 “Can I prove who I am?”\, but “Can I prove what you need to know wit
 hout telling you who I am?”
