Why Your Brain Craves Coffee

Why Your Brain Craves CoffeeFor a long time, the man has held us down. They used their science and medicine to tell is that ingesting coffee, or more accurately the caffeine in coffee, was bad.

Freddie Mercury drinking coffeeTimes they are a changing we no longer have to justify drinking coffee to anybody. Recent research carried out by many free-thinking independent medical professionals from universities and health care institutes has shown that actually, caffeine has many benefits to our bodies and minds.

The caffeine present in our daily coffee can help us to live longer, have more mental ability and focus, fight depression and even help us to lose weight. What’s not to love about the nation’s favorite drink?

Fed up of justifying your coffee freedom to the man? This infographic from Dripped Coffee gives use 13 reasons why our brains carve coffee.

Mind Readers Can Steal Your Info

Mind Readers Can Steal Your InfoBy now, most people have come to position that passwords suck. The momentum for alternate means of authentication is growing. Researchers are working on how to use biometrics for mainstream login activities. As I have pointed out there are number of emerging biometric techniques like; iris scans, facial recognition, or behavioral characteristics. All of these methods have flaws, which pose a problem for authentication non-repudiation.

Passwords suckIn a post at IEEE Spectrum, Megan Scudellari writes that Fingerprints can be stolen, iris scans spoofed, and facial recognition software fooled. In the wake of these flaws researchers have turned to brain waves as the next step in biometric identification. Biometric identification is any means by which a person can be uniquely identified by evaluating one or more distinguishing biological traits. Unique identifiers include fingerprints, hand geometry, earlobe geometry, retina and iris patterns, voice waves, DNA, and signatures.

The researchers are racing to prove how accurately and accessibly they can verify a person’s identity using electroencephalograph (EEG) data. An EEG is a test that detects electrical activity in the brain using electrodes attached to the scalp. The IEEE article explains that as your eyes skim over these pixels you are reading and turn them into meaningful words, your brain cells are flickering with a pattern of electrical activity that is unique to you. These unique patterns can be used like a password or biometric identification. In fact, researchers have taken to calling them “passthoughts”.

EEGUsing brainwaves to authenticate people goes back awhile. Back in 2012, I wrote about the Muse headband sensor which promised to “create a specific brainwave signature or a password they would never have to say out loud or type into a computer.” More recently, psychologists and engineers at Binghamton University in New York achieved 100 percent accuracy at identifying individuals using with brain waves captured with a skullcap with 30 electrodes. Scientists at the University of California at Berkeley have adapted a set of earbud sensors that worked with 80 percent accuracy.

The problem is our brains don’t produce a single, clear signal that can be checked like a fingerprint. The article says our brains emit a messy, vibrant symphony of personal information, including one’s emotional state, learning ability, and personality traits. The author contends that as EEG technology become cheaper, portable, and more ubiquitous—not only for identity authentication, but in apps, games, and more— there’s a high likelihood that someone will tap into that concerto of information for malicious purposes. Abdul Serwadda, a cyber security researcher at Texas Tech University told Spectrum;

If you have these apps, you don’t know what the app is reading from your brain or what [the app’s creators are] going to use that information for, but you do know they’re going to have a lot of information

The Texas Tech team performed experiments to see if they could glean sensitive personal information from brain data captured by two popular EEG-based authentication systems. Surprise, surprise: they were able to capture sensitive personal information from brain data.

Capture sensitive personal information from brain data

Mr. Serwadda presented his results at the IEEE International Conference on Biometrics. The Texas Tech researchers examined EEG-based authentication systems that claimed high levels of authentication accuracy. One system examined was the Berkley model; and the second was based on the Binghamton model. The article explains that these EEG-based authentication systems utilize specific features, or markers, of brain activity to identify a person, like isolating the melody of a specific orchestra instrument to identify a song.

Isolating the melodyThe researchers wanted to see if those markers also contained sensitive personal information—in this case, a tendency for alcoholism. They ran old EEG scans which included alcoholics and non-alcoholics through the systems. Using the brain wave data, they were able to accurately identify 25% of the alcoholics in the sample. That’s 25% of people who just lost their privacy. Mr. Serwadda said;

We weren’t surprised, because we know the brain signal is so rich in information … But it is scary. [Wearable brain measurement] is an application that’s just about to go mainstream, and you can infer a lot of information about users.

The researcher said that malicious third parties could mine brain data to make inferences about learning disabilities, mental illnesses, and more. He told Spectrum, “Imagine if you made these things public, and insurance companies became aware of them … It would be terrible.”

IOActive senior consultant Alejandro Hernández told The Register  that dangerous vulnerabilities exist in EEG kits. EEG’s security problems are depressingly familiar results of bad software design, Hernández said. EEG devices are vulnerable to man-in-the-middle attacks, as well as less-severe application vulnerabilities and ordinary crashes. Mr. Hernández says.

… some applications send the raw brain waves to another remote endpoint using the TCP/IP protocol, that by design doesn’t include security, and therefore this kind of traffic is prone to common network attacks such as man-in-the-middle where an attacker would be able to intercept and modify the EEG data sent.

The IOActive consultant found that components like the acquisition device, middleware, and endpoints lack authentication meaning an attacker can connect to a remote TCP port and steal raw EEG data. That same flaw lets attacks pull off the more dangerous reply attacks.

Unfortunately, the researchers do not have a solution for how to secure such information—though in the study, compromising a little on authentication accuracy did reduce the ability to detect who was an alcoholic. Mr. Serwadda hopes other research teams will now take privacy, and not just accuracy, into account when optimizing such systems. Professor Serwadda concludes, “We have to prepare for the movement of brain wave [assessment] into our daily lives.”


Given the willingness of apps developers to sell share any info to any third party and the unwillingness of the public to take even basic steps to secure their info online, everyone’s deepest personal information can be hacked in the future.

Another problem with passthoughts UC Berkeley’s John Chuang identifies that stress, mood, alcohol, caffeine, medicine, and mental fatigue could change the electrical signals that are generated.

Despite advances in logging in with your mind, there might always be a need for an old-fashioned eight-plus character phrase with no spaces. “Passwords will never go away,” says Berkeley’s Chuang. He reasons that for a computer, a typed password may be the easiest way to verify identity, while a finger swipe may be best for a touch screen.

But we need to think beyond those to future devices—wearables, for instance—for which there will be neither a keyboard nor a touch screen. “For each device, we must figure out what are the most natural, intuitive ways to tell the device that we are who we are,” Professor Chuang says. Going directly to the brain seems like an obvious choice.

Emoji Passcodes Replace PIN at ATM

Emoji Passcodes Replace PIN at ATMFollowers of the Bach Seat know that passwords are evil. I have written about dumb passwords again, again and again. Now a firm in the UK wants us to replace out ATM PINs with Emoji passcodes. The Verge brings us the latest theory to get users to use passwords better than “123456,” “password,” and “12345678.” EMOJI. Yes those Japanese pictographs that anybody over 15 loves to hate. 

EMOJI KNEE HIGH SOCKSSince most users just don’t care about their passwords Intelligent Environments, a UK firm that makes digital banking software, has created what it’s calling the “world’s first emoji-only passcode,” offering a choice of 44 emoji that can be used to create a four-character PIN. The company told the Verge the 44 emoji can create 3,498,308 possible permutations for non-repeating emoji passcodes, compared to just 7,290 for traditional non-repeating PIN.

The firm believes that everyone loves emoji, so why not replace those pesky digits emoji?  Intelligent Environments is betting that forcing people to use emoji instead of numbers would also stop them choosing PINs based on memorable events — birthdays and weddings for example — that might be easily guessed. The comany quotes Tony Buzan, inventor of the Mind Map technique who, adds that the idea “plays to humans’ extraordinary ability to remember pictures, which is anchored in our evolutionary history.” Memory expert Buzan explains, “Forgetting passwords is because the brain doesn’t work digitally or verbally. It works imagistically.”

TPassword dresshe author points out while it is a clever idea, certainly, but don’t get too excited yet: it’s not the first PIN replacement we’ve seen, and implementing these ideas is always far more difficult than just coming up with them. Intelligent Environments’ press release is also little too heavy on the hyperbole (it claims that “64 percent of millennials regularly communicate only using emojis” — really? Only using emoji?) and a little too light on actual industry support. Intelligent Environments’ managing director David Webber told BBC News that the company hadn’t patented the idea, meaning any bank that wants to introduce emoji PIN codes can do so. Although, there’s always the chance that security wouldn’t be increased as everyone picked what is objectively the best emoji passcode ever: four smiling poops.

There is some research that says this makes sense. But then there is the problem of getting systems to accept the emoji PIN. There are still web-sites out there that can’t handle a passphrase of more than 12 text characters, what is it going to do with emoji? Also remember that there are still lots of ATM’s out there quietly running Microsoft’s Windows XP operating system more than two years after Redmond stopped updating the software.

The kids think they are so cool with their newfangled emoji. What about old-school?
