Account Aggregator framework requires Financial Information Providers to share customer financial data only on valid consent artefacts with digital signing. FIPs in the securities markets must share specified financial information only upon receipt and verification of a valid electronic consent artefact from the customer via an AA, digitally sign and transmit that information in real time, implement interfaces to authenticate consent artefacts, verify digital signatures, maintain logs of sharing requests and adopt published technical specifications and IT safeguards to ensure secure, scalable data flows to AAs.
