The New York Times reports: When government officials came to Silicon Valley to demand easier ways for the world’s largest Internet companies to turn over user data as part of a secret surveillance program, the companies bristled. In the end, though, many cooperated at least a bit.

Twitter declined to make it easier for the government. But other companies were more compliant, according to people briefed on the negotiations. They opened discussions with national security officials about developing technical methods to more efficiently and securely share the personal data of foreign users in response to lawful government requests. And in some cases, they changed their computer systems to do so.

The negotiations shed a light on how Internet companies, increasingly at the center of people’s personal lives, interact with the spy agencies that look to their vast trove of information — e-mails, videos, online chats, photos and search queries — for intelligence. They illustrate how intricately the government and tech companies work together, and the depth of their behind-the-scenes transactions.

The companies that negotiated with the government include Google, which owns YouTube; Microsoft, which owns Hotmail and Skype; Yahoo; Facebook; AOL; Apple; and Paltalk, according to one of the people briefed on the discussions. The companies were legally required to share the data under the Foreign Intelligence Surveillance Act. People briefed on the discussions spoke on the condition of anonymity because they are prohibited by law from discussing the content of FISA requests or even acknowledging their existence.

In at least two cases, at Google and Facebook, one of the plans discussed was to build separate, secure portals, like a digital version of the secure physical rooms that have long existed for classified information, in some instances on company servers. Through these online rooms, the government would request data, companies would deposit it and the government would retrieve it, people briefed on the discussions said.

The negotiations have continued in recent months, as Martin E. Dempsey, chairman of the Joint Chiefs of Staff, traveled to Silicon Valley to meet with executives including those at Facebook, Microsoft, Google and Intel. Though the official purpose of those meetings was to discuss the future of the Internet, the conversations also touched on how the companies would collaborate with the government in its intelligence-gathering efforts, said a person who attended.

Twitter, Google and other companies have typically fought aggressively against requests they believe reach too far. Google, Microsoft and Twitter publish transparency reports detailing government requests for information, but these reports do not include FISA requests because they are not allowed to acknowledge them.

Yet since tech companies’ cooperation with the government was revealed Thursday, tech executives have been performing a familiar dance, expressing outrage at the extent of the government’s power to access personal data and calling for more transparency, while at the same time heaping praise upon the president as he visited Silicon Valley.

Even as the White House scrambled to defend its online surveillance, President Obama was mingling with donors at the Silicon Valley home of Mike McCue, Flipboard’s chief, eating dinner at the opulent home of Vinod Khosla, the venture capitalist, and cracking jokes about Mr. Khosla’s big, shaggy dogs.

The Guardian reports: At the end of the first day of the his summit with the Chinese premier Xi Jinping in California, the president described disclosures about the National Security Agency’s access to telephone and internet data as “a very limited issue”.

However in comments that appeared more emollient than his remarks earlier in the day, when he criticised “leaks” and “hype” in the media, Obama tried to deflect criticism, saying internet privacy posed “broad implications for our society”. He said privacy concerns also related to private corporations, which he said collect more data than the federal government.
