US President Barack Obama meets Internet bosses on Friday to discuss his latest plans to overhaul US spy agency surveillance practices which have infuriated the industry.

Obama was expected to meet company chiefs including Google executive chairman Eric Schmidt and Facebook founder Mark Zuckerberg who said last week he had called the president personally to express frustration with the vast online intelligence dragnets.

A White House official said the meeting was to continue Obama's "dialogue with them on the issues of privacy, technology, and intelligence."

The White House was expected to release the names of all of those at the meeting later.

The scope of the National Security Agency spying network, revealed in leaks to the media by fugitive intelligence contractor Edward Snowden, has sparked tensions between the administration and Silicon Valley.

Recent reports have spurred the concern, including allegations that the NSA imitated a Facebook server to inject malware into computers to expand its intelligence collection capacity.

The report by former Guardian reporter Glenn Greenwald said the NSA malware could collect data automatically from millions of computers worldwide.

Some Snowden documents suggest the NSA had access to servers of Facebook, Google and Yahoo.

The firms have strongly denied giving any access except under a legal requirement, and have said more transparency about the programs could reassure their customers.

Zuckerberg said in a Facebook post after speaking to Obama that he had expressed "frustration over the damage the government is creating for all of our future."

"Unfortunately, it seems like it will take a very long time for true full reform."

Obama introduced new guidelines for NSA programs in January but many of the proposed reforms are yet to be formulated by the agency itself and Congress.

Obama proposed ending the NSA's hoarding of bulk telephone metadata. Although he said the program must go on in some form, he was less specific about reforms on Internet surveillance.

The NSA and its supporters say the surveillance programs, which critics charge infringe civil liberties and the US constitution, are vital for tracing terror networks across the globe and thwarting attacks.
