India jumped into the BlackBerry controversy Thursday by demanding that Research in Motion allow Indian law enforcement access to Blackberry Enterprise Service and Blackberry Messenger Service data by Aug. 31.
If RIM refuses, the country will "take steps to block these two services from the network," India's Ministry of Home Affairs said in a statement.
India wants its law enforcement agencies to have access to the information traveling via BES and BBM for surveillance purposes. The country already has access to BlackBerry voice, text, and Internet services, the ministry said.
"Although RIM cannot disclose confidential regulatory discussions that take place with any government, RIM assures its customers that it genuinely tries to be as cooperative as possible with governments in the spirit of supporting legal and national security requirements, while also preserving the lawful needs of citizens and corporations," RIM said in a statement.
RIM said it has "drawn a firm line" and insisted that any carriers that provide BlackBerry services adhere to four basic principles: the carriers' capabilities be limited to the strict context of lawful access and national security requirements; the carriers' capabilities must be technology and vendor neutral; no changes will be made to the security architecture for BlackBerry Enterprise Server customer since; and RIM maintains a consistent global standard for lawful access requirements that does not include special deals for specific countries.
India is just the latest country to threaten to shut down BlackBerry services. Earlier this month, the United Arab Emirates said it would block BlackBerry services by Oct. 11 over similar concerns. Saudi Arabia followed suit several days later, promising to shut down service by Aug. 6, but officials relented this week, and said they would allow BlackBerry services to remain while talks continued.
At issue is the encrypted network over which BlackBerry data travels. After the announcement from the UAE, RIM said it offers one BlackBerry enterprise solution to all its customers, and does not favor one country's government over another.
"The BlackBerry enterprise solution was designed to preclude RIM, or any third party, from reading encrypted information under any circumstances since RIM does not store or have access to the encrypted data," RIM said at the time. "RIM cannot accommodate any request for a copy of a customer's encryption key, since at no time does RIM, or any wireless network operator or any third party, ever possess a copy of the key. This means that customers of the BlackBerry enterprise solution can maintain confidence in the integrity of the security architecture without fear of compromise."
Twitter on Thursday unveiled its "tweet" button, which will let users share links on Twitter directly from the Web site they are visiting. About one-quarter of all tweets include a link, but sharing those links can sometimes be complex, Twitter spokeswoman Carolyn Penner wrote in a blog post.
"Copying and pasting, link shortening, and bouncing between browser tabs just to share a link in a Tweet is too much work," Penner wrote. To simplify the process, Web site owners can now add a few lines of code to their pages for quick tweeting. When a user clicks on the "tweet" button, a pop-up box will appear. The Web site URL will already be shortened, so all a user has to do is add a message and click "tweet." It will be sent to a user's Twitter feed automatically, and that user can continue browsing. Twitter has also incorporated its follow suggestion feature into the tweet button. After a user sends off a tweet, Twitter will suggest a few people it thinks you might want to follow. Select those people or just click out of the box.
Twitter said the tweet button can be added to sites of all sizes – from recreational bloggers to major media organizations. More than 30 sites will start using the tweet button on Thursday, including CNN.com, Hulu, Gawker Media, The Onion, and USA Today.
"It only takes a few lines of code," Penner wrote. "The tweet Button will help publishers grow traffic and increase their Twitter following." For those wondering how this offering differs from the "retweet" buttons that already populate many Web sites, that was a feature produced by third-party company TweetMeme. Going forward, Penner said Twitter will be working with Tweetmeme and incorporating its "retweet" button into the tweet button.
"What does this mean? Firstly we will be assisting Twitter with the technical challenges involved with the button and secondly we will be working even more closely in the future on delivering real-time curation of the Twitter Firehose," TweetMeme founder and CEO Nick Halstead wrote in a blog post.
The partnership will result in the launch of new TweetMeme products, Halstead said, the first of which he unveiled Thursday. DataSift will give developers "the ability to leverage cloud computing to build very precise streams of data from the millions and millions of tweets sent every day," he wrote.

As physician-guided robots routinely operate on patients at most major hospitals, the next generation robot could eliminate a surprising element from that scenario -- the doctor.
Feasibility studies conducted by Duke University bioengineers have demonstrated that a robot -- without any human assistance -- can locate a man-made, or phantom, lesion in simulated human organs, guide a device to the lesion and take multiple samples during a single session. The researchers believe that as the technology is further developed, autonomous robots could some day perform many more simple surgical tasks. "Earlier this year we demonstrated that a robot directed by artificial intelligence can on its own locate simulated calcifications and cysts in simulated breast tissue with high repeatability and accuracy," said Kaicheng Liang, a former student in the laboratory of Stephen Smith, director of the Duke University Ultrasound Transducer Group at the Pratt School of Engineering and senior member of the research team. "Now we have shown that the robot can sample up to eight different spots in simulated human prostate tissue."
The results of the Duke research appear in the current issue of the journal Ultrasonic Imaging. An earlier study reported in the January issue of the journal Ultrasound in Medicine and Biology described the Duke team's results on simulated breast tissue. In both experiments, whole turkey breasts were used. Raw turkey breasts are commonly used in medical research because the tissue closely resembles that of humans in texture and density, and appear similar when scanned by ultrasound.
The Duke team combined a "souped-up" version of an existing robot arm with an ultrasound system of its own design. The ultrasound serves as the robot's "eyes" by collecting data from its scan and locating its target. The robot is "controlled" not by a physician, but by an artificial intelligence program that takes the real-time 3-D information, processes it and gives the robot specific commands to perform. The robot arm has a mechanical "hand" that can manipulate the same biopsy plunger device that physicians use to reach a lesion and take samples. In the latest series of experiments, the robot guided the plunger to eight different locations on the simulated prostate tissue in 93 percent of its attempts. This is important because multiple samples can also determine the extent of any lesion, Smith said.
Smith believes that routine medical procedures, such as biopsies in other tissues in the body, will be performed in the future with minimal human guidance, and at greater convenience and less cost to patients.
An important challenge to be overcome is the speed of data acquisition and processing, though the researchers are confident that faster processors and better algorithms will address that issue. To be clinically useful, all of the robot's actions would need to be in real time, the researchers said.
"One of the beauties of this system is that all of the hardware components are already on the market," Smith said. "We believe that this is the first step in showing that with some modifications, systems like this can be built without having to develop a new technology from scratch." Advances in ultrasound technology have made these latest experiments possible, the researchers said, by generating detailed, 3-D, moving images in real-time. The Duke team has a long track record of modifying traditional 2-D ultrasound -- like that used to image babies in utero -- into the more advanced 3-D scans. The Duke lab invented the technique in 1991.
"We're now testing the robot on a human mannequin seated at the examining table whose breast is constrained in a stiff bra cup," Smith said. "The breast is composed of turkey breast tissue with an embedded grape to simulate a lesion. Our next step is to move to an excised human breast." The research in Smith's lab is supported by the National Institutes of Health. Other members of the team were Edward Light and A.J. Roberts from Duke, and Daniel von Allmen from Cincinnati Children's Hospital Medical Center.
