Secure Message Lifecycle Management Using Off-Chain Storage and Blockchain-Anchored Event Records

Resumen de: AU2026200240A1

Abstract A computer-implemented method for managing secure message content is described. Message content associated with a message is received and stored in an off-chain content store. A payload identifier is generated that uniquely identifies the content independently of its physical storage location, and a first cryptographic hash of the stored content is computed. An off-chain mapping store holds a mapping record keyed by the payload identifier, including location data for retrieving the content and the first hash. A message event item including the payload identifier, the first hash and message lifecycle data is serialised into a canonical representation, hashed to obtain an event hash, and immutably anchored on a blockchain. Upon a subsequent access request, the associated message event item is re- serialised and verified against the blockchain event hash before the payload identifier is used to locate and retrieve the content. A third hash of the retrieved content is compared with the first hash to decide whether to release or withhold the content. Abstract an b s t r a c t a n g o C) an a n : o
