The number of people hiding their identity while surfing the web has risen in the past year.

Research shows that the level of “encrypted” internet activity has risen dramatically across the world, suggesting that millions of people have begun to use software that hides who they are while accessing the web.

According to Sandvine, the technology networking company, hidden internet traffic in peak hours in Europe has been up to 6.1 per cent of all web activities compared with about 1.5 per cent a year earlier. In North America encrypted traffic went up to 3.8 per cent from 2.3 per cent a year earlier, while in Latin America it jumped to almost 10.4 per cent from 1.8 per cent.

Experts said that the changes in online behavior were the result of exposure(曝光) about widespread internet spying by intelligence agencies, such as that exposed by Edward Snowden, the US National Security Agency whistleblower.

“It will be interesting to see how these trends develop,” said Ernesto Van der Sar, the pen-name used by the editor-in-chief of Torrentfreak.com, the website that first reported the figures. “In any case, it’s clear that internet services and their users are becoming more aware of their privacy online, which is generally a good development.”

Last week Sir Tim Berners-Lee, the British inventor of the web, defended the right of agencies to spy on the internet for law enforcement (强制实施) . He said, “We have to figure out how to balance that against rights.”
