The advocacy group has started an online petition that people can sign to show their support for the bill. The American Civil Liberties Union, Privacy Rights Clearinghouse and other consumer groups also back the bill.
California Assembly member Bonnie Lowenthal (D-Long Beach) introduced the measure earlier this year as an update to a state law passed in 2003. The bill would update the existing law's definition of personal information, so companies would have to disclose whether they have collected data on people's location information, purchasing history and sexual orientation, among other details. It would also expand the current law's scope so the measure would require companies to disclose which data brokers, online advertisers and other Web entities they share people's information with.
"Today, our personal data is everywhere – we share it when using mobile phone apps, search engines and websites like Facebook and Twitter. Companies buy and sell it for profit. As technology advances, so should our consumer protections," Lowenthal said in a statement when she introduced the measure in February.
EFF's Reitman also added in the blog post that the proposed "law mimics the rights of data access already available to users in Europe, which means that most of the big tech companies should already have systems in place to facilitate user access."
The bill is expected to be heard in the California State Assembly's Judiciary Committee later this month.
