DigiTrust

Former industry consortium initiative for universal ID, now defunct

DigiTrust was a non-profit consortium initiative launched in 2017 to create a universal user ID solution for the digital advertising industry. The initiative aimed to address the fragmentation caused by third-party cookie restrictions and provide a privacy-compliant alternative for user identification across the web. DigiTrust operated as an industry utility, offering a standardized framework for publishers and advertisers to recognize users while maintaining transparency and user control over data sharing. The consortium was backed by major industry players and operated under a governance model designed to ensure neutrality and privacy protection. DigiTrust's technology provided a consistent identifier that could be used across participating publishers and platforms, reducing the need for cookie syncing and improving advertising efficiency. However, the initiative was ultimately shut down in 2020 following IAB Tech Lab's acquisition of the technology, with the decision influenced by evolving privacy regulations and browser changes that made third-party identifier solutions increasingly challenging to maintain.
