In cryptography a blind signature, as introduced by David Chaum, is a form of digital signature in which the content of a message is disguised (blinded) before it is signed. The resulting blind signature can be publicly verified against the original, unblinded message in the manner of a regular digital signature. Blind signatures are typically employed in privacy-related protocols where the signe… WebBlinding is a concept in cryptography that allows a client to have a provider compute a mathematical function y = f ( x ), where the client provides an input x and retrieves the corresponding output y, but the provider would learn about neither x nor y.
