"If reelected, British Prime Minister David Cameron would consider banning messaging apps like Snapchat and WhatsApp, if they don't make their data available to intelligence agencies, he said Monday."

"With news that the 15 million Twitter users in the UK can now be targeted at individual postcode levels, the micro-blogging platform is selling its advertising opportunities as ultra-geographically precise, and therefore ultra-cost effective. "The key benefit of geo-targeting is that it enables advertisers, or in this case political parties, the ability to reach users in specific regions, metropolitan areas and now postcodes," Twitter said in a blog post. "

"Rutgers University's new program also uses a "behavior observation tool," which monitors student browser activity throughout an active session. While this feature is intended to prevent students from using the Internet to cheat on exams, the power that this grants instructors is extremely invasive. If a student accidentally leaves a personal or embarrassing website in their browser during an online course, a ProctorTrack instructor might stumble upon their activity."

"Selling data is as yet a small part of Twitter's overall income - $70m out of a total of $1.3bn last year, with the lion's share of cash coming from advertising, but the social network has big plans to increase that. Its acquisition of Chris Moody's analytics company Gnip for $130m last April is a sign of that intent. Google and Facebook have built their businesses around sharing data, but their control of our private and public information has become a source of huge controversy. "

"Luckily for the kid, it was only a single tweet. Had several students gotten together to form a study group, they might have been prosecuted for felony interference with a business model and gotten the death penalty. Do you suppose Pearson has hidden microphones set up around the schools so they can also listen in and see if students discuss the tests during lunch? I ask because that is basically the offline version of the student's infraction."

"Pearson is apparently monitoring social media, to detect signs of cheating during exams. That's insanely creepy, and a horrible violation. "And for those who think "Well, its Twitter, its public", remember this: So is walking down the street. But is it OK for the government to monitor us with street surveillance cameras and send us fines for not crossing with the crosswalk?" via Pearson Caught Spying On Students. Big Brother Is Here. "

"America's National Security Agency gathers unfathomable mountains of Internet communications from fiber optic taps and other means, but it says it only retains and searches the communications of "targeted" individuals who've done something suspicious. Guess what? If you read Boing Boing, you've been targeted."

"The NSA uses laughably sloppy tools for deciding whether a target is a "US person" (a person in the USA, or an American citizen abroad). For example, people whose address books contain foreign persons are presumed by some analysts to be foreign. Likewise, people who post in "foreign" languages (the US has no official state language) are presumed by some analysts to be non-US persons."

"A new algorithm, however, is attempting to identify specific syndromes much sooner by screening photos for characteristic facial features associated with specific genetic conditions, such as Down's syndrome, Progeria, and Fragile X syndrome."

"Jimmy Wales said it was dangerous to have companies decide what should and should not be allowed to appear on the internet. His comments came after the bosses of the leading search engines met the heads of European data watchdogs on Thursday."

Scary but if we are not careful - could be true in the future - "Existing properties will be required to install them over a four-year period. These would supply real-time images of terrorists, criminals and paedophiles at any time of day and night. Any disconnection of a camera would immediately alert the police as prima facie evidence of wrongdoing. I have held talks with the industry on whether the cameras should be in bathrooms and bedrooms. It would clearly be nonsensical to exclude them, as terrorists and paedophiles often make use of these rooms."

"A story on the site of the Japanese broadcaster NHK shows how this is playing out in the world of social networks. Online criticism of the behavior of the President of South Korea following the sinking of the ferry MV Sewol prompted the government to set up a team to monitor online activity. That, in its turn, has led people to seek what the NHK article calls "cyber-asylum" -- online safety through the use of foreign mobile messaging services, which aren't spied on so easily by the South Korean authorities. According to the NHK article: Many users have switched [from the hugely-popular home-grown product KakaoTalk] to a German chat app called Telegram. It had 50,000 users in early September. Now 2 million people have signed up."

"But the bigger problem with things like public tweets is that no-one knows what information can be derived from them, either now or in the future. I write as a data analyst who's done a fair bit of work with this kind of material. What follows are a few techniques that aren't at all obvious to the average Twitter user. They go far beyond reading the surface text (or metadata) of an individual tweet. And these are just some of the techniques currently used to mine this data, ethically or unethically, legally or illegally."

"Graduated top of your class in Ghana and managed to land a place on an MBA at Oxford? Then you're heading for a salary high enough to make repaying your student loan a cinch - especially if half your Facebook followers are from McKinsey. At least, this is the kind of calculation being made by private funders stepping into the increasingly complex and competitive student loans market."

""Many predicted at the outset that Google would simply agree to most requests for removal to save time and money," said Barron. "That hasn't happened - 60% of removal requests have been rejected. Every single request is considered by our teams and there is no automation. If their judgment is challenged by the publisher we will reconsider and, if a mistake has been made, we will reinstate." "

"Teatreneu's administrators found an ingenious solution: partnering with the advertising agency Cyranos McCann, they fitted the back of every seat with fancy tablets that can analyse facial expressions. Under the new model, visitors enter the club for free but have to pay 30 cents for every laugh recognised by the tablet - with a cap of €24 (or 80 laughs) per show. A mobile app makes it easier to complete the payment; the overall ticket prices have reportedly gone up by €6. As a bonus, you can also share your smiling selfie with friends: the path from funny to viral has never been shorter."

"Now, the number of combinations of these columns grows exponentially with the number of columns. So if you have many, many columns-and we do in modern databases-you'll get up into millions and millions of attributes for each person. Now, if I start allowing myself to look at all of the combinations of these features-if you live in Beijing, and you ride bike to work, and you work in a certain job, and are a certain age-what's the probability you will have a certain disease or you will like my advertisement? Now I'm getting combinations of millions of attributes, and the number of such combinations is exponential; it gets to be the size of the number of atoms in the universe."

"While 77% of shoppers in a recent study by Opinion Lab said in-store tracking is unacceptable, 61% also responded that they expect to be compensated with cost-saving discounts if they're tracked. How stores sell in-store tracking to shoppers and highlight its benefits is where one of the next major battles of retail will be fought, Kilcourse says. "

"Going from small data analytics to Big Data analytics or to predictive and prescriptive analytics is trickier. Expanding in both dimensions is human capital intensive, requiring talented data scientists. A McKinsey report (2011) estimates that by 2018, there will be a shortage of 140,000 to 190,000 workers with "deep analytical" experience and a further 1.5 million data-literate managers in the US. Technology giants such as Google, Facebook and Amazon, and large investment banks and top hedge funds can afford such employees, however even now the competition is fierce, as is evidenced by the ongoing talent war in Silicon Valley. The data scientist is indeed a sexy job in the 21st century."

"Shodan is a search engine for the Internet of Things, scanning the public Internet for devices communicating on ports and over protocols that are commonly used by IoT devices. By feeding it the right parameters -- Real Time Streaming Protocol (RTSP, port 554) -- you can find innumerable publicly shared webcams, ranging from CCTVs that oversee marijuana grow-ops and many, many baby-monitors.
