Little-known CCPA provision could be a game changer, Global Privacy Control advocates believe

An obscure provision in the California Consumer Privacy Act (CCPA) could be the key to effective data sharing opt-outs, according to some privacy experts.  The rule gives consumers the right opt-out from data sales through a “global privacy control” which would automatically apply to all Web sites they visit.  Privacy advocates including the CEO of DuckDuckGo believe compliance can be achieved with a signal sent by browsers alerting websites of a user’s opt-out preference. Unlike previous Do Not Track efforts, this would have the force of law, at least in California.  DuckDuckGo and other browser companies have been building the signal into their products and project that 40 million users will be sending it in the near future.
