BRUSSELS >> The head of Apple today endorsed tough privacy laws for both Europe and the U.S. and renewed the technology giant’s commitment to protecting personal data, which he warned was being “weaponized” against users.

Speaking at an international conference on data privacy, Apple CEO Tim Cook applauded European Union authorities for bringing in a strict new data privacy law this year and said the iPhone maker fully supports a U.S. federal privacy law.

Cook’s remarks, along with comments due later from Google and Facebook top bosses, in the European Union’s home base in Brussels, underscore how the U.S. tech giants are jostling to curry favor in the region as regulators tighten their scrutiny.

Data protection has become a major political issue worldwide, and European regulators have led the charge in setting new rules for the big internet companies. The EU’s new laws on data privacy require companies to change the way they do business in the region, and a number of headline-grabbing data breaches have raised public awareness of the issue.

“In many jurisdictions, regulators are asking tough questions. It is time for rest of the world, including my home country, to follow your lead,” Cook said.

“We in Apple are in full support of a comprehensive federal privacy law in the United States,” he said, to applause from hundreds of privacy officials from more than 70 countries.

In the U.S., California is moving to put in regulations similar to the EU’s strict rules by 2020 and other states are mulling more aggressive laws. That’s rattled the big tech companies, which are pushing for a federal law that would treat them more leniently.

Cook warned that technology’s promise to drive breakthroughs that benefit humanity is at risk of being overshadowed by the harm it can cause by deepening division and spreading false information. He said the trade in personal information “has exploded into a data industrial complex.”

“Our own information, from the everyday to the deeply personal, is being weaponized against us with military efficiency,” he said.

Cook’s appearance seems set to one-up his tech rivals and show off his company’s credentials in data privacy, which has become a weak point for both Facebook and Google.

“With the spotlight shining as directly as it is, Apple have the opportunity to show that they are the leading player and they are taking up the mantle,” said Ben Robson, a lawyer at Oury Clark specializing in data privacy. Cook’s appearance “is going to have good currency,” with officials, he added.

Facebook CEO Mark Zuckerberg and Google head Sundar Pichai were scheduled to address by video the annual meeting of global data privacy chiefs. Only Cook, who has been outspoken on protecting user privacy, attended in person.

He has repeatedly said that privacy is a “fundamental human right” and vowed his company wouldn’t sell ads based on customer data the way companies like Facebook do.

His speech comes a week after the iPhone maker unveiled expanded privacy protection measures for people in the U.S., Canada, Australia and New Zealand, including allowing them to download all personal data held by Apple through a new website and letting users make corrections. European users already had access to this feature after the continent’s General Data Protection Regulation, or GDPR, took effect in May. Apple plans to expand it worldwide.

The International Conference of Data Protection and Privacy Commissioners, held in a different city every year, normally attracts little attention but its Brussels venue this year takes on symbolic meaning as EU officials ratchet up their tech regulation efforts.

The 28-nation EU took on global leadership of the issue when it beefed up data privacy regulations by launching GDPR. The new rules require companies to justify the collection and use of personal data gleaned from phones, apps and visited websites. They must also give EU users the ability to access and delete data, and to object to data use.

GDPR also allows for big fines benchmarked to revenue, which for big tech companies could amount to billions of dollars.

In the first big test of the new rules, Ireland’s data protection commission, which is a lead authority for Europe as many big tech firms are based in the country, is investigating Facebook after a data breach let hackers access nearly 30 million accounts, including 3 million for EU users. Separately, the bloc’s consumer protection chief has warned Facebook it could face sanctions for being slow to clarify the fine print in its terms of service concerning what happens to user data. And the EU competition chief has opened a preliminary investigation of Amazon over how it uses data from merchants.

Google, meanwhile, shut down its Plus social network this month after revealing it had a flaw that could have exposed personal information of up to half a million people. It’s also fighting a European order that it extend “right to be forgotten” rules to its search engines globally, in a battle pitting privacy concerns against the public’s right to know.
