Western governments need to restore public trust in the internet following revelations of online surveillance made by former US intelligence operative Edward Snowden, according to Microsoft.
The technology company's vice president Brad Smith said:

We obviously all want to live in a secure world but we all want to live in a world as well where security is balanced with personal freedom and privacy.
We recognise that information technology is a powerful tool for individuals but people won't use technology they don't trust. In our view governments have put that trust at risk. Governments need to help restore it.
Google says that intelligence gathering techniques used by the US and other governments are putting web users' online security at risk.
The online giant's senior vice president Ken Walker said: "We have invested so much in encryption and the fight for transparency around government requests for information.
"That's undermined when you have wholesale collection of data done in secret without independent oversight by many governments around the world," Walker told the BBC Radio 4 Today programme.
Eight of the world's largest technology firms are to publish an open letter to US President Barack Obama today calling for greater regulation of online data collection by intelligence agencies, the Guardian reports.
Apple, Google, Microsoft, Facebook, Yahoo, LinkedIn, Twitter and AOL have all thrown their weight behind a package of reforms being debated in Congress.
They warn that the ongoing disclosures by former intelligence analyst Edward Snowden risk undermining public "trust in the internet," the Guardian reports.
"The balance in many countries has tipped too far in favour of the state and away from the rights of the individual – rights that are enshrined in our constitution,” the letter reportedly says.
The announcement of small business grants for high speed broadband coincides with the Small Business Saturday initiative promoting the firms Mr Cameron described as the "lifeblood of our economy".
– Prime Minister David Cameron
Up to £3,000 of broadband vouchers for small business in these cities is not only a massive boost for growth in the UK, but also has the potential to bring China to Cardiff, Brazil to Bristol and the Emirates to Edinburgh in an increased export market.
To do that we are working on a complete overhaul of the UK's infrastructure; high speed broadband is a vital part of this. And on Small Business Saturday, what better way to support small businesses - the lifeblood of our economy - than to help kit them out for the 21st century.
Small businesses in 10 cities across the UK will be able to apply for grants to install high speed broadband as part of a £100 million scheme to boost growth and exports.
Firms in Belfast, Salford, Portsmouth, Cardiff, Derby, Bristol, Edinburgh, Newport, London and Manchester will be able to access grants worth up to £3,000 to improve their connections, with the scheme due to be extended to 12 more cities next year.
Prime Minister David Cameron said he wanted to give firms the ability to set up or locate anywhere in the UK.

We are today announcing the closure of a further 62 stores across the United Kingdom and a further 427 jobs as part of the effective phased closure as announced on 28 November.
Unfortunately we have still not received any acceptable offers so as a result we may be forced to close the remaining 91 stores affecting 808 employees.
Social media users who knowingly break court orders by posting prohibited information online, such as the identities of James Bulger's killers, can "easily" be prosecuted, a legal expert has warned.
Joshua Rozenberg explained: "If you can show that somebody knew that there was a court order in force, as this man last week, who was very nearly sent to prison - in the end he got a suspended sentence and a hefty financial penalty.
"But if you know that there is a order saying you can't publish a picture of Jon Venables, then it is obviously more easy for the Attorney General to prosecute you."
Careless tweets have landed a host of celebrities in trouble in the past with comedian Alan Davies, Sir Bob Geldof's daughter Peaches and Sally Bercow all finding themselves in legal difficulties due to their online posts.
