Google Improves Data Privacy Via ‘Confidential Matching’
Google added encryption to a core advertising product intended to secure an advertiser's customer information during a time when more data is being used to serve personalized ads. The technology, turned on by default, also ensures transparency into a product’s code and the ability to receive proof -- known as “attestation” -- that data is processed as intended. It is the first time the technology -- which Google calls confidential computing -- has been used in Google's advertising products, but the company plans to bring it to more products over time.
