TikTok trialling new ad-targeting tool with enhanced data privacy


TikTok is trialling a new ad-targeting tool that reportedly offers improved data privacy protection.

PrivacyGo operates like a data clean room, where separate parties can input multiple sets of data and find commonalities without sharing the original source.

Why we care. If PrivacyGo works as expected, this tool will provide marketers with deeper insights into who their target audience is, enabling them to make more efficient data-led decisions to improve campaign performance. The technology will also enhance TikTok’s ad-targeting capabilities, helping brands to reach the right people as well as previously untapped audiences. If TikTok is able to achieve these goals while adhering to evolving data privacy regulations, advertisers’ trust and confidence in the platform will inevitably increase, which will likely lead to more ad spend.

How it works. PrivacyGo functions by implementing a type of cryptography known as multi-party computation, or MPC, reports Business Insider. This technology is able to identify common audiences between multiple sets of data, while ensuring none of the parties have access to it. The US Government uses a similar approach to review census data, according to TikTok, and so the platform is hoping this will reassure officials that its data privacy protection is sufficient.

Why now? TikTok is still under investigation by the CFIUS over data privacy concerns and allegations it has been leaking data to the Chinese government. If the platform is found to be violating any data privacy regulations, it faces a full ban in the US. With that in mind, it’s little wonder TikTok is exploring different methods to improve its data privacy capabilities.
