Abstract: ABSTRACT: Title: System and Method for Cryptographic Invalidation of Transaction-Bound Identity Tokens Based on Verified Output Hash The present disclosure proposes systems and methods for lifecycle management of identity transaction tokens associated with authorized computational transactions. The output-hash-bound identity transaction token revocation system (100) comprises a computing device (102) having a processor (104) and memory (106). The processor (104) executes plurality of modules (108) for issuing and associating an identity transaction token with an authorized transaction, verifying transaction completion through a cryptographic completion attestation, validating a task output, and invalidating the token upon successful verification. The plurality of modules (108) comprises an authorization-service module (110), transaction-association module (112), completion-attestation receiving module (114), attestation-verification module (116), completion-state verification module (118), output-hash verification module (120), and token-invalidation module (122). The system (100) rejects subsequent presentation of an invalidated token and prevents unverified or mismatched completion indications from causing token invalidation.
