Computers are really, really good at recognizing faces… For people who don’t want to be found, or just enjoy the previously unquestioned ability to travel without being tracked, facial recognition poses a risk. As a solution, Japan’s National Institute of Informatics (NIII) created glasses that make faces unreadable to machines.

I sometimes wonder, How much data am I generating? Meaning: how much data do I generate just sitting there in a chair, doing nothing except exist as a cell within any number of global spreadsheets and also as a mineable nugget lodged within global memory storage systems — inside the Cloud, I suppose. (Yay Cloud!)
“Let’s post our credit card numbers and even those pesky CSV codes on the back. (Better yet, let’s just do away with credit cards altogether because, at the end of that day, it’s just a bank taking on the risk that you’ll pay back a loan.) Let’s post our social security numbers and our driver’s licenses. Let’s post everything. Overnight, the incentives to steal your data are wiped off the face of the earth. The dark databases are worth zero.”
Last year, my personal credit cards and banks were breached five times. Last week, another personal breach. Each time, I was informed by email and snail mail, a new credit card or bank account was issued, and I bought more monitoring for my credit or, in the case of one of the breaches, the company that was breached bought additional monitoring. About the fourth time, I started wondering why our industry doesn’t do something else. The traditional IT security model is dead, but we just keep propping up the body. Hope has become our strategy in the cyber security war. Read more
The National Security Agency knows Edward Snowden disclosed many of its innermost secrets when he revealed how aggressive its surveillance tactics are. What it doesn’t know is just how much information the whistleblower took with him when he left.
For all of its ability to track our telecommunications, the NSA seemingly has little clue exactly what documents, or even how many documents, Snowden gave to the media. Like most large organizations, the NSA had tools in place to track who accessed what data and when. But Snowden, a system administrator, apparently was able to cover his tracks by deleting or modifying the log files that tracked that access. Read more
We’ve suspected it all along—that Skynet, the massive program that brings about world destruction in the Terminator movies, was just a fictionalization of a real program in the hands of the US government. And now it’s confirmed—at least in name.
As The Intercept reports today, the NSA does have a program called Skynet. But unlike the autonomous, self-aware computerized defense system in Terminator that goes rogue and launches a nuclear attack that destroys most of humanity, this one is a surveillance program that uses phone metadata to track the location and call activities of suspected terrorists. A journalist for Al Jazeera reportedly became one of its targets after he was placed on a terrorist watch list. Read more

It’s taken close to half a decade. But WikiLeaks is back in the business of accepting truly anonymous leaks.
On Friday, the secret-spilling group announced that it has finally relaunched a beta version of its leak submission system, a file-upload site that runs on the anonymity software Tor to allow uploaders to share documents and tips while protecting their identity from any network eavesdropper, and even from WikiLeaks itself. The relaunch of that page—which in the past served as the core of WikiLeaks’ transparency mission—comes four and a half years after WikiLeaks’ last submission system went down amid infighting between WikiLeaks’ leaders and several of its disenchanted staffers.

Dozens of smartphone apps collect so much location data that their publishers can plot users’ comings and goings in detail, a forthcoming peer-reviewed study found.
Computer scientists at Carnegie Mellon University concluded that a dozen or so popular Android apps collected device location – GPS coordinates accurate to within 50 meters – an average 6,200 times, or roughly every three minutes, per participant over a two-week study period.
The research comes at a time of increasing concern about electronic privacy. A 2014 Pew survey found that more than 90 percent of Americans feel they’ve lost control over personal data. While savvy users understand that using mobile devices entails some privacy tradeoffs – for example, a navigation app will reveal their location to the app’s publisher – most don’t realize the extent to which such information is collected and distributed, the researchers said.

Bitcoin as a cryptocurrency has had its moments of strength and weakness. The technology behind bitcoins, however, is a different story. While skeptics don’t expect a lot from Bitcoin as an alternative currency because of its volatility, they do have high hopes for the technological innovation that powers it, believing that it can be further developed to create something much powerful than Bitcoin itself.
To those who know Bitcoin as a great way of transacting online, but don’t completely understand its dynamics, it’s time to get acquainted with the cryptocurrency’s mathematical wonders that make anonymous, faster, and cheaper transactions of moving funds on the internet possible.
Most of us know that Bitcoin uses the SHA-256 hashing algorithm, but hashing serves a different function and purpose from that of digital signatures. Hashing actually provides proof that a message has not been changed because running the same hash always generates similar result.
Any message, regardless of the size can go into a hash function where the algorithm breaks it down, combines the parts, and “digests” it until it makes a fixed-length outcome called “digest”. However, a good hashing algorithm possesses some critical characteristics, in which the same message always produces the same result, as mentioned above, and it only works in one direction.
This means that even the smallest change creates a completely different digest. This is called the “avalanche effect”. Also, the chances of generating the same digest from a transformed message are a tad rare. This is called “collision resistance”.
Such nature of Bitcoin’s hash function makes it impossible to change records and transactions once they have been documented. As soon as the hashes are hashed together within the blockchain, counterfeiting records of transactions is no way near possible.
Then there’s the technology of wallet software. This is where people store bitcoins and use for making transactions. The wallet system is set in which users are prohibited from spending the same units twice (double-spending) by checking new transactions against the blockchain and against other new transactions to ensure the same units are not being cited more than once.
Though this system was established to avoid fraudulent activities and has proven to be an effective one, it also became an ideal scenario for hacking attacks on a Bitcoin exchange that aim to steal bitcoins. It’s because once bitcoins are lost, they’re gone for good and there’s no way of reclaiming them, especially that cryptocurrency usage is not covered by the central government and other intermediary parties like banks. Nonetheless, it’s not totally the Bitcoin’s fault; it’s the Bitcoin exchanges’ security measures.
