WASHINGTON >> The Trump administration is hoping Congress can come up with a new set of national rules governing how companies can use consumers’ data that finds a balance between “privacy and prosperity.”

But it will be tricky to reconcile the concerns of privacy advocates who want people to have more control over the usage of their personal data — where they’ve been, what they view, who their friends are —and the powerful companies that mine it for profit.

Senior executives from AT&T, Amazon, Apple, Google, Twitter and Charter Communications are scheduled to testify at the hearing, amid increasing anxiety over safeguarding consumers’ data online and recent scandals that have stoked outrage among users and politicians.

Sen. John Thune, a South Dakota Republican who heads the Senate Commerce Committee, opened Wednesday’s hearing by saying there’s a strong desire by both Republicans and Democrats for a new data privacy law.

But the approach being pondered by policymakers and pushed by the internet industry leans toward a relatively light government touch. That’s in contrast to stricter EU rules that took effect in May.

An early move in President Donald Trump’s tenure set the tone on data privacy. He signed a bill into law in April 2017 that allows internet providers to sell information about their customers’ browsing habits. The legislation scrapped Obama-era online privacy rules aimed at giving consumers more control over how broadband companies like AT&T, Comcast and Verizon share that information.

Allie Bohm, policy counsel at the consumer group Public Knowledge, says examples abound of companies not only using the data to market products but also to profile consumers and restrict who sees their offerings: African Americans not getting access to ads for housing, minorities and older people excluded from seeing job postings.

The companies “aren’t going to tell that story” to the Senate panel, she said. “These companies make their money off consumer data.”

What is needed, privacy advocates maintain, is legislation to govern the entire “life cycle” of consumers’ data: how it’s collected, used, kept, shared and sold.

Meanwhile, regulators elsewhere have started to act.

The 28-nation European Union put in strict new rules this spring that require companies to justify why they’re collecting and using personal data gleaned from phones, apps and visited websites. Companies also must give EU users the ability to access and delete data, and to object to data use under one of the claimed reasons.

A similar law in California will compel companies to tell customers upon request what personal data they’ve collected, why it was collected and what types of third parties have received it. Companies will be able to offer discounts to customers who allow their data to be sold and to charge those who opt out a reasonable amount, based on how much the company makes selling the information.

Andrew DeVore, Amazon’s vice president and associate general counsel, told the Senate panel today that it should consider the “possible unintended consequences” of California’s approach. For instance, he says the state law defines personal information too broadly such that it could include all data.

The California law doesn’t take effect until 2020 and applies only to California consumers, but it could have fallout effects on other states. And it’s strong enough to have rattled Big Tech, which is seeking a federal data-privacy law that would be more lenient toward the industry.

“A national privacy framework should be consistent throughout all states, pre-empting state consumer-privacy and data security laws,” the Internet Association said in a recent statement. The group represents about 40 big internet and tech companies, spanning Airbnb and Amazon to Zillow. “A strong national baseline creates clear rules for companies.”

The Trump White House said this summer that the administration is working on it, meeting with companies and other interested parties. Thune’s pronouncement and one from a White House official stress that a balance should be struck in any new legislation — between government supervision and technological advancement.

The goal is a policy “that is the appropriate balance between privacy and prosperity,” White House spokeswoman Lindsay Walters said. “We look forward to working with Congress on a legislative solution.”
