DAA

DAA is an acronym that can refer to several unrelated entities in technology, data governance, and transportation. Notable uses include Digital Advertising Alliance, Direct Anonymous Attestation, Data Access Agreement, and the Dublin Airport Authority’s branding.

In digital advertising, the Digital Advertising Alliance (DAA) is a coalition of advertising and marketing associations in the United States that promotes privacy and responsible online advertising practices. It administers a self-regulatory program for online behavioral advertising and provides consumer opt-out tools and resources, such as the DAA Choices mechanism.

In cryptography and hardware security, Direct Anonymous Attestation (DAA) is a protocol developed by the Trusted Computing Group. It enables privacy-preserving attestation of trusted devices by allowing a platform to prove it possesses a valid credential without disclosing its identity. DAA is associated with trusted platform modules (TPM) and is relevant for secure attestation in cloud and hardware environments.

In data sharing and research governance, a Data Access Agreement (DAA) is a contract governing access to and use of data between organizations. A DAA typically outlines the purpose of data use, permitted operations, data security measures, retention and destruction timelines, publication restrictions, and compliance with privacy laws such as the GDPR or HIPAA.

In transportation, daa refers to the Dublin Airport Authority, a state-owned organization that operates Dublin Airport in Ireland. The brand has been styled as daa in contemporary branding, while the legal entity remains involved in airport infrastructure and operations.
