Replace Your Password With Brainwaves? Yes, Really


Replace Your Password With Brainwaves? Yes, Really - It sounds like something straight out of science fiction, but someday you may be able to access your computer just by thinking.


Professor John Chuang with the Neurosky MindSet brainwave sensor.Researchers at the UC Berkeley School of Information claim that computer brainwave-based authentication is an effective and secure substitution for manually entered passwords. 

By using sensors to register electroencephalograms, or brainwave measurements, computers can recognize brainwaves and allow you to access your accounts via what the researchers call "pass-thoughts" rather than by typing a code consisting of letters, numbers and other characters. 

With companies like Google and Microsoft reportedly looking for new ways to improve their password security systems, brainwave authentication may present opportunities. 

In conducting their experiments, professor John Chuang and engineering and computer science student Charles Wang used the Neurosky MindSet, a $199 brainwave-reading headset connected to a computer with Bluetooth technology. 

Study participants were asked to wear the headset and perform seven mental tasks. In the first three, participants all did the same thing, such as focusing on their breathing or imagining moving a finger up and down. 

The other four tasks were customized. For example, participants were asked to visualize a repetitive motion from a sport of their choice or concentrate on any one thing for 10 seconds.

In total, the tasks provided enough information to authenticate the individual user, according to the study. 

This isn't the first time that using brainwaves has been proposed as a replacement for passwords. But until now, the technology needed to authenticate brainwaves has been expensive and invasive. 

With highly effective, low-cost EEG sensors, though, the idea doesn't seem so far-fetched. Aside from the small sensor, the headset that the researchers used in their experiment was no different than than a Bluetooth headset. ( CNBC )

Can You Guess What's the Worst Password to Have?


Can You Guess What's the Worst Password to Have? - Occasionally I'm forced to change my password to access financial and benefits information. It's a pain, requiring me to memorize something new, but I'm glad I have to do it. An easy password is the online equivalent of leaving your front door open or running into a store with your car running.

How easy are some passwords? As easy as "123123"…literally. 

SplashData has released the list of worst passwords of 2012, and "123123" is #16 on the list of 25. 

Most surprising, the number one bad password is…"password". 

Really? 

I can only assume someone using "password" as his or her password is: 

Brilliant, because no identity thief would ever suspect something so obvious. 

Stupid, because identity thieves know better. 

Has nothing worth stealing. 

SplashData has added some passwords to its list for the first time: "welcome", "jesus", "ninja", "mustang", and my favorite, "password1". That extra digit will show 'em! 

Certain passwords are moving up and down the list compared to last year. The password "football" has moved up five spots to #20, while the ironic password "trustno1" has dropped three points to #12, after a lot of people realized they really should trust no one. ( CNBC )

SIx Ways to Protect Your Work Computer


SIx Ways to Protect Your Work Computer - A group of hackers claims to have stolen the IDs of 12 million Apple devices from an FBI laptop. Possibly yours.

These IDs are like serial numbers for iPads and iPhones – except they’re also linked to personal information, including cell phone numbers, addresses, user names, and other details that could be used for identity theft.

The FBI has denied both the theft and having the data in the first place. A company called Blue Toad that makes apps and digital platforms later claimed it was the one hacked. But wherever the data came from, hackers leaked what they claim are 1 million of those IDs, stripped of the personal data. You can find out if your device number was leaked at The Next Web. (They also tell you how to locate your number – it’s in iTunes.)

Muslim's Articles

It’s not clear how the data was stolen – if the hackers were telling the truth about the method but not the source, then they exploited an outdated piece of software on an employee’s laptop. They could do the same to yours.

And there are easier ways a hacker can access your computer that not enough people think about. A recent CareerBuilder survey of more than 3,800 workers found a majority don’t lock up their laptop when away from their desk. Some freely shared their passwords and made other silly mistakes. Here’s what you can do to protect your computer (including your personal device)…

1. Use a complex password

Enable a log-in password on your computer if it doesn’t already have one. Make sure it’s not one you use elsewhere and not one you’ve shared with anyone else. The survey reports 27 percent have heard a co-worker give out a password – and 12 percent admitted to keeping the password written down nearby. Not smart, since your co-worker could be an identity thief.

The best passwords are long, contain special characters or nonconsecutive numbers, and either don’t use real words or are several words nonsensically chained together, something like: “wrenchsqueeze3ightmonkeyyel!0w.”

2. Maintain updated software

Nine percent of those surveyed admitted to downloading a virus at work. If your employer doesn’t provide antivirus software – or if it stinks – try Microsoft Security Essentials. It’s free and good. (Mac users, try Avast!)

Keep the program and your system up to date to avoid new security vulnerabilities. Also make sure you’re using a firewall. PCs and Macs both come with built-in firewall software.

Also keep any Web browser plug-ins you need for work – such as Java, Flash, and Adobe Reader – up to date. It’s a chore, but that’s exactly why hackers target them. CSO, a security and risk management publication, says these exploits can have high success rates because “users are not deploying the available security updates in a timely fashion.” If you can avoid using Java altogether, you should – lately it’s a hacker favorite.

3. Avoid suspicious links, websites, and attachments

Take extra care to avoid clicking sensational headlines on social media, and watch your typing: Going to appple.com instead of apple.com could put you at risk of a virus. Hackers snatch up these “typosquatter” domains you might accidentally visit. Also avoid opening email attachments from people you don’t know – because 18 percent said they did this or visited an unsecure website.

4. Prevent physical theft

Protecting your files online is important, but so is making sure somebody doesn’t walk off with the computer while you’re in the bathroom – 1 in 20 workers surveyed experienced such a theft. So get a laptop security cable (less than $15) and use it when you’re away from the computer. And don’t leave the laptop in your car.

5. Get tracking software

Get permission from your boss or IT guy to install software that can locate your laptop if it gets stolen – and possibly identify the thief through its webcam. There’s a free (or for multiple devices, cheap) program called Prey that works for most major operating systems. Check out this funny story I did about a guy who used it to catch a laptop thief from hundreds of miles away.

6. Separate personal and professional

The survey mentioned earlier found 48 percent had company info on their laptops, and 27 percent had client information. That might be unavoidable – but 18 percent also had personal financial details and other information – which is an unnecessary risk. Keep those files on your personal home computer or a removable hard drive. ( Money Talks News )
