Abstract: ABSTRACT SYSTEM AND METHOD FOR VPA-ANCHORED CRYPTOGRAPHIC VERIFICATION OF QR-BASED MERCHANT PAYMENT CODES WITH SIMILARITY-GATED ONBOARDING A merchant identity verification system (100) having a registry (106) maintaining an index of registered merchant identifiers and corresponding public keys, and a merchant device (102) configured to generate an asymmetric key pair and submit a proposed merchant identifier and a proposed display name to the registry (106) for registration. An onboarding engine (104) communicatively coupled to the registry (106) receives the proposed merchant identifier and display name, applies a homoglyph normalization function to produce normalized strings, decomposes the normalized strings into trigram sets, retrieves a bounded candidate set by computing a trigram-set Jaccard coefficient, computes a normalized Levenshtein edit distance between the normalized strings and each candidate, withholds issuance of a signing key pair and rejects registration when the edit distance meets or exceeds a similarity threshold, and upon the edit distance falling below the threshold admits a public key to the registry (106) indexed by the proposed merchant identifier.
