Designing an Efficient Image Encryption-Then-Compression System via Prediction Error Clustering - Video

In the wake of Edward Snowdens revelations about the NSA collecting massive amounts of user meta-data, many people went in search of safer, more secure ways to use the internet anonymously. Once thought to be something only used by the tech-savvy, increased interest in end-to-end e-mail encryption has prompted both Google and Yahoo to develop user-friendly versions of the protocol that would, in theory, make personal messages exceedingly difficult to intercept.

GeeksPhone, a Spanish hardware manufacturer, and Silent Circle, U.S. communication firm, promise to provide the same kind of privacy with Blackphone, the first fully encrypted smartphone meant for the average consumer. While technically an Android device, Blackphone runs a forked version of the operating system called PrivatOS that rids the phone of any and all connections to Googles servers.

Encrypting e-mail is effective, but requires that both the sender and recipient of a message use the same specific encryption protocol to maintain privacy. Blackphone, for all of the protection that it provides, cuts users off from most of the serviceslike games, maps, and other functionsso as to make sure that there are absolutely no gaps through which information might be extracted.

The Onion Router also known as Tor, a browser designed keep users entirely anonymous, is something of a happy medium, and the NSA is actively trying to scare people away from it. Tor guides its internet traffic through complex networks of layered encryption that hide a computers physical location and make it nearly impossible to monitor the IP addresses that it visits.

Post-Snowden, Tor saw a substantial increase in the number of people using its browser and network, undoubtedly in-part due to privacy concerns. Documents published by The Guardian revealed that the NSA were actively engaged with attempting to infiltrate Tors network, and considered the browser to be the king of high-secure, low-latency anonymity. Following widespread, successful-attempts at tracking Tor users activity, the FBI openly admitted to exploiting a loophole in Tors infrastructure as a part of a larger operation in pursuit of a child pornography ring.

Authorities have justified their pushes into the anonymous internet, asserting that by and large, much of Tors traffic is related to illegal activities, but that seems to be changing. Richard David James, better known by his stage name Aphex Twin, is a fixture in the electronic music scene. Earlier this week James announced his latest album using a website that could only be accessed using Tor, drawing in a significant number of pageviews in a single day.

The attention, says Tor executive director Andrew Lewman, is both a blessing and a curse. While Tors network was able to handle the 133,000 visits that Aphex Twin drew, he doubts whether it could withstand the kinds of gargantuan traffic that Facebook sees on a daily basis. Tor users, comparatively speaking, are rarea fact that Lewman asserts is what makes them targets for governmental organizations.

Its been co-opted by GCHQ and the NSA that if youre using Tor, you must be a criminal, Lewman explained to The Guardian. I know the NSA and GCHQ want you to believe that Tor users are already suspect, because, you know, god forbid who would want their privacy online, they must be terrorists.

Proponents of Tor and other forms of ubiquitous encryption have called for the public to adopt the technologies on a larger scale, logic stating that if everyone is using encryption, then no one can be singled out for it. Rather than adopting the small, experimental proofs of concept like Tor, Lewman says, true privacy on the internet will come when internet juggernauts like Facebook, Twitter, and Google incorporate the technology into their platforms, making them the standard rather than the exception.

As governments invade privacy, tools for encryption grow more popular

This week, MacNN forum-goers discuss a wide range of topics including encryption software, consistent crashes, and how to cool down a hot Mac. One Fresh-Faced Recruit was wondering if there was some kind of one-click encryption solution that could encrypt a file before it is uploaded to cloud storage, and decrypt it when it is needed again. Moderator "Rumor" reported their third crash in one day, and was hoping fellow forum goers could help troubleshoot and get to the root cause of this problem.

Useful tips on how to deal with a problematic MagSafe charger connection can be found in the thread titled "can't get the charge plug to stay connected charge-wise," where one Senior User had their problem resolved. In a post started by "chasg" earlier this month, forum-goers continue to discuss ways to determine what might be making an iMac run hot, and how to fix it. Yesterday, "rotuts" was asking fellow forum-goers if anyone had any opinions on Apple's USB DVD drive, wondering if they should use their $100 Apple credit on something else instead.
