Tokyo, February 1, 2023 --- D.A.Consortium Inc. (DAC) is pleased to announce that AudienceOne ID^®(*1), an integrated ID technology for digital targeting services on AudienceOne^®, a DMP developed and provided by DAC, will begin linkage with ID5 ID, an ID solution provided by ID5 (headquarters: United Kingdom; Co-founder and CEO: Mathieu Roche). With this, advertisers will be able to increase the volume of users who can be identified without relying on cookies. In addition, advertisers will be able to deliver ads via ID5 ID using third-party data owned by AudienceOne^®, thereby enabling advertisers, ad agencies, media companies and solution vendors to continue to deliver ads effectively and efficiently even in a post-cookie era.

With the rising demand for web-based user privacy protection, countries around the world are formulating laws and regulations related to data gathering and utilization. With increasingly strict regulations on the use of cookies, which are widely used for conventional targeted advertising and ad effectiveness measurements, there is a pressing need to develop post-cookie era alternative technologies and methodologies for the future of digital marketing.

To respond to these challenges, DAC develops and provides a wide range of solutions for a post-cookie era. For example, DAC offers a first-party data utilization platform　for ad effect measurements called WISE Transformer(*2). For audience data utilization, DAC developed an integrated ID technology for its DMP, AudienceOne^® and a targeted digital advertising delivery service. To further enhance its services, DAC has decided to link with ID5 ID.

■The effect of linking AudienceOne ID^® with ID5 ID
ID5 ID is a next-generation universal identifier that recognizes user-authorized user IDs on a wide variety of devices without using conventional user identification methods, such as third-party cookies or mobile ad IDs (MAID). ID5 ID features both the ability to protect userdata and highly accurate user identification. By linking ID5 ID with AudienceOne ID^® user information on hobbies and interests, advertisers, media companies and DSP/SSP operators can fulfill their campaign goals and communicate with users based on their interests as they have in the past.

１．Enhanced ID solution functions for a post-cookie era
Adding ID5 ID to the ID generation logic of AudienceOne^® ID, the integrated ID technology of AudienceOne^®, enhances post-cookie ID solutions functions, for example, by increasing the volume of users who can be identified without relying on cookies and other tools.

２．Seamless linkage with ID5 ID-compatible solutions
Solutions that are compatible with ID5 ID, such as Magnite, PubMatic and other SSPs, as well as MediaMath, The Trade Desk, Criteo and other DSPs, can be seamlessly linked. As a first step, we will link with the DSP, MediaMath (*3).

３．Ability to use third-party data associated with AudienceOne ID^®
Through ID5 ID, clients can access third-party data owned by AudienceOne^® and communicate with users based on interests, hobbies and other attributes. This function enables communication that links this data with the attributes of users associated with AudienceOne^® ID.

■Comment from Joanna Burton, Chief Strategy Officer (CSO), ID5
“At ID5, we are committed to providing a new and improved addressability infrastructure to empower all digital advertising players to thrive without traditional identifiers. Our partnership with AudienceOne signifies another positive step towards achieving this goal at a global scale," said Joanna Burton, Chief Strategy Officer at ID5. "We look forward to our continued work with AudienceOne, enabling them to maintain a valuable service for their advertiser clients even after third-party cookies are gone.”

DAC will continue to actively enhance its AudienceOne^® services and provide optimal solutions to promote our client companies’ marketing activities.
