Gadgetwise Blog: Q&A: Using Skype or FaceTime

Does Skype work on an iPad for video calls, and, if so, does it have any advantages over Apple’s FaceTime system?

Skype, now owned by Microsoft, does have an app for the iPad. You can find instructions for getting started with it on the Skype site.

One of the biggest advantages Skype has over Apple’s FaceTime app is that you can make audio and video calls to other Skype users around the world on more types of hardware. This includes calling Windows and Mac computers, Android devices, Windows Phone handsets and even certain Skype-enabled televisions and Blu-ray players. Skype-to-Skype calls are free, and for a bit of money, you can call regular telephone numbers.

In comparison, Apple’s FaceTime app is also free for one-to-one video calls, but it only works on certain Apple-made products. These include camera-equipped iOS devices made within the past few years and Macs running OS X 10.6 and later. Still, because it is integrated into the operating system, FaceTime can be a little easier to set up and use if you plan to chat only with people carrying Apple gear.

Video and audio quality in both apps may vary based on network and data traffic issues, especially if you are calling over a 3G or 4G cellular connection instead of Wi-Fi. Since both apps are free for video calls, there is nothing stopping you from using both as you need them — or even adding Google Plus Hangouts into the mix if you are a member there, too.

Special Report: Technology and Innovation: Microsoft Inherits Sticky Data Collection Issues From Skype

BARCELONA — When Microsoft, the world’s largest software maker, bought Skype in May 2011 for $8.5 billion, it acquired not only the technology behind the world’s dominant Internet voice and video service, but a connection with more than 250 million active users.

But perhaps what Microsoft did not anticipate when it made the purchase was that it would inherit the delicate privacy aspects of Skype’s business, including its billions of encrypted, peer-to-peer Internet conversations.

Those conversations, and the access Microsoft grants to them, are now the focus of a lobbying campaign by 50 digital rights groups and dozens of individuals.

In a letter sent in January, the group asked Microsoft to disclose what data it collected from Skype users and whether that data was passed on — whether to potential advertisers or to law enforcement agencies conducting criminal investigations.

The group, a collection of Internet activists from around the world that includes the Electronic Frontier Foundation, Reporters Without Borders and Zwiebelfreunde, a German university group, called on Microsoft to begin publishing regular transparency reports listing the requests made by government agencies for Skype client information around the world.

Amid the pressure, there are signs that Microsoft may be preparing to relent and publish what are known as transparency reports, which disclose the level of government requests for information. Google has provided the reports since 2010. Since then, Twitter and LinkedIn, among others, have moved toward offering regular reports — but not Microsoft.

Besides public disclosures, said Eva Galperin, a global policy analyst at the Electronic Frontier Foundation, the group also wanted to know the location of Skype’s headquarters — whether in Luxembourg, as it was before it was acquired by Microsoft, or at Microsoft’s base in Redmond, Washington.

The location is important, Ms. Galperin said, because if Skype’s headquarters are in the United States, Microsoft and Skype would be required to comply with requests made by U.S. intelligence services under Calea, the Communications Assistance for Law Enforcement Act, which gives agencies easier access to monitor data from online businesses like Skype.

Internet activists in countries with authoritarian regimes also need to know whether their Skype conversations, once considered a hack-proof way of avoiding government phone wiretaps because of the peer-to-peer nature of the exchanges, are still secure, she said.

“What we know right now is that we don’t know,” said Paul Bernal, a lawyer and professor of technology, intellectual property and media law at the University of East Anglia in Norwich, England, one of 61 individuals who also signed the open letter to Microsoft.

“We need to know how Microsoft and Skype cooperate with law enforcement and others around the world,” Mr. Bernal said. “People living under authoritarian regimes need to know what kinds of personal risks they are taking when using Skype.”

Dominic Carr, a Microsoft spokesman in Redmond, said that Skype’s headquarters, even after the purchase, remained in Luxembourg and the company was subject to laws of Luxembourg and the European Union, not the United States.

Luxembourg, like other E.U. countries, has mutual assistance pacts and other legal mechanisms that permit companies like Microsoft to share information with foreign law enforcement agencies in continuing investigations. The purchase of Skype by Microsoft has not changed the ability of law enforcement to gain access to Skype data, Mark Gillett, a corporate vice president responsible for Skype engineering and operations, wrote in a blog post.

According to Microsoft’s published privacy policy, three types of information are generated by Skype: personally identifiable information on users; nonidentifiable information; and the actual contents of Skype-to-Skype audio and video conversations.

Syria Rebels Find Skype Useful, but Dangers Lurk

When Syria’s Internet service disappeared Thursday, government officials first blamed rebel attacks. Activist groups blamed the government and viewed the blackout as a sign that troops would violently clamp down on rebels.

But having dealt with periodic outages for more than a year, the opposition had anticipated a full shutdown of Syria’s Internet service providers. To prepare, they have spent months smuggling communications equipment like mobile handsets and portable satellite phones into the country.

“We’re very well equipped here,” said Albaraa Abdul Rahman, 27, an activist in Saqba, a poor suburb 20 minutes outside Damascus. He said he was in touch with an expert in Homs who helped connect his office and 10 others like it in and around Damascus.

Using the connection, the activists in Saqba talked to rebel fighters on Skype and relayed to overseas activists details about clashes with government forces. A video showed the rebels’ bare-bones room, four battery backups that could power a laptop for eight hours and a generator set up on a balcony.

For months, rebels fighting to overthrow President Bashar al-Assad have used Skype, a peer-to-peer Internet communication system, to organize and talk to outside news organizations and activists. A few days ago, Jad al-Yamani, an activist in Homs, sent a message to rebel fighters that tanks were moving toward a government checkpoint.

He notified the other fighters so that they could go observe the checkpoint. “Through Skype you know how the army moves or can stop it,” Mr. Yamani said.

On Friday, Dawoud Sleiman, 39, a member of the antigovernment Ahrar al-Shamal Battalion, part of the Free Syrian Army, reached out to other members of the rebel group. They were set up at the government’s Wadi Aldaif military base in Idlib, a province near the Turkish border that has seen heavy fighting, and connected to Skype via satellite Internet service.

Mr. Sleiman, who is based in Turkey, said the Free Syrian Army stopped using cellphone networks and land lines months ago and instead relies almost entirely on Skype. “Brigade members communicate through the hand-held devices,” he said.

This week rebels posted an announcement via Skype that called for the arrest of the head of intelligence in Idlib, who is accused of killing five rebels. “A big financial prize will be offered to anyone who brings the head of this guy,” the message read. “One of our brothers abroad has donated the cash.”

If the uprisings in Tunisia and Egypt were Twitter Revolutions, then Syria is becoming the Skype Rebellion. To get around a near-nationwide Internet shutdown, rebels have armed themselves with mobile satellite phones and dial-up modems.

In many cases, relatives and supporters living outside Syria bought the equipment and had it smuggled in, mostly through Lebanon and Turkey.

That equipment has allowed the rebels to continue to communicate almost entirely via Skype with little interruption, despite the blackout. “How the government used its weapons against the revolution, that is how activists use Skype,” Mr. Abdul Rahman said.

“We haven’t seen any interruption in the way Skype is being used,” said David Clinch, an editorial director of Storyful, a group that verifies social media posts for news organizations, including The New York Times (Mr. Clinch has served as a consultant for Skype).

Mr. Assad, who once fashioned himself as a reformer and the father of Syria’s Internet, has largely left the country’s access intact during the 20-month struggle with rebels. The government appeared to abandon that strategy on Thursday, when most citizens lost access. Some Syrians could still get online using service from Turkey. On Friday, Syrian officials blamed technical problems for the cutoff.

The shutdown is only the latest tactic in the escalating technology war waged in Arab Spring countries.

But several technology experts warned that the use of the Internet by rebels in Syria, even those relying on Skype, could leave them vulnerable to government surveillance.
