Design requirement R4.3: Authenticity checks
Another often disregarded requirement for a complete trust chain is that sharing or selling KYC documents among customers must be prevented. The customer needs to be able to convince the bank that the KYC-related documents that they present were not stolen, sold, or shared. We call this requirement authenticity checks, meaning that the identity of the customer and their connection with the documents must have a high level of assurance even if the customer is not present at a branch and no video call is held.
