A Phone That Reads Your Fingerprint, Ctd

A reader writes:

Your post quotes another article that states thumbprints are “convenient and, at least in theory, uncrackable.” Uncrackable? Bruce Schneier, security expert, differs:

So…can biometric authentication be hacked? Almost certainly. I’m sure that someone with a good enough copy of your fingerprint and some rudimentary materials engineering capability — or maybe just a good enough printer — can authenticate his way into your iPhone.

Another adds:

I’m sure VanHemert means well when he says a fingerprint is, in theory, uncrackable – but it’s the opposite. The phone would need to access the encrypted print data on the hard drive in order to authenticate the person unlocking the device, which provides another point of access for someone to break into the phone. With any kind of security measure, the less points of access, the better.

Readers also respond to a recent post on heartbeat-based access:

Speaking as one of the millions of people with cardiac arrhythmias, I would be out of luck if a “heartbeat recognition” system was adopted to replace passwords.

EKGs are not analogous to fingerprints. When I’m in normal sinus rhythm, the system would work as advertised and I would be recognizable. However, I have frequent, random episodes where my heart goes out of pattern. These episodes can be momentary or last for hours, and during an episode my heart rate and rhythm pattern goes all over the place. During those episodes, I would presumably be locked out of my Nymi-encrypted device because it wouldn’t recognize my EKG. A conservative estimate is that four million Americans suffer from atrial fibrillation, various tachycardias, sick sinus syndrome, flutter, heart block, or WPW. Despite our electrical problems, most of us are productive members of society. But we’d lose productivity if heartbeat recognition gained ground.

And September is Atrial Fibrillation Awareness Month, so I’d like to make the healthy tech developers aware that their idea is a non-starter for this fast-growing segment of the population.

Yep, Atrial Fibrillation Awareness Month is a real thing. Another reader:

Unfortunately all biometric-based authentication has a fatal flaw. This includes fingerprints, eye scans, and even heartbeats. The problem is that the data can be copied. And once it is copied there is no way to change it.

When your account password is compromised, it is possible to change it. This is impossible for biometric identification. You can’t change your fingerprint or your eye scan or your heartbeat. It is also always available to anyone who cares to copy it. There is nothing stopping your doctor from copying all of your biometric information and using it to impersonate you. This is not possible with passwords, unless you explicitly give them out at the time you type it, which is only a few times a day. Your body is available to anyone you are around all the time.

Passwords provide the strongest possible security guarantee. Which is absolutely necessary for any Internet-based service. Anything online is accessible to anyone in the entire world. That means you have to defend against the most advanced sophisticated genius level criminal attackers out there.

There is a place for biometric-based authentication. It is good to use in addition to passwords. But it can never be a solid foundation alone. It is the ability to be completely inside your head and not stored anywhere else that makes passwords theoretically uncrackable. In practice you need to choose a good password and not re-use them nor be fooled into giving them away.

The Best Of The Dish Today

As the dust settled from the remarkable decision by the Russians and the Syrians to secure and destroy Assad’s chemical weapons arsenal, I asked: who got played? Any student of Machiavelli would suspect it was Putin who got the bad end of the deal, even as he preened and postured as the victor. And the quixotic campaign to coax the US to somehow take responsibility for that sectarian bloodbath – let alone resolve it – is shown by history to be close to insane. There has never been a peaceful or non-sectarian Syria, largely because it was designed by the British and French to be the seething mess it is. And nation-building Syria is about as intelligent as nation-building in Iraq.

But the Dish is never about politics alone: we also covered the poignancy of Johnny Cash; the role of crystal meth in the tragedy of Matthew Shepard; the life of Norma Holt; an astonishing short film on aging; and the beard of the week!

The most popular post was Machiavelli’s take on Putin’s swagger; and the latest neoconservative illusion artist.

See you tonight on AC360 Later at 10 pm, and in the morning.

The Sages Of Cyberspace

Henry Farrell considers what it means to be a public intellectual in the Internet age:

Many of these new public intellectuals are more or less self-made. Others are scholars (often with uncomfortable relationships with the academy, such as Clay Shirky, an unorthodox professor who is skeptical that the traditional university model can survive). Others still are entrepreneurs, like technology and media writer and podcaster Jeff Jarvis, working the angles between public argument and emerging business models. These various new-model public intellectuals jostle together in a very different world from the old. They aren’t trying to get review-essays published in Dissent or Commentary. Instead, they want to give TED talks that go viral. They argue with one another on a circuit of business conferences, academic meetings, ideas festivals, and public entertainment. They write books, some excellent, others incoherent.

In some ways, the technology intellectuals are more genuinely public than their predecessors.

The little magazines were just that, little. They were written for an elite and well-educated readership that could be measured in the tens of thousands. By contrast, TED talks are viewed 7.5 million times every month by a global audience of people who are mostly well-educated but are not self-conscious members of a cultural elite in the way that the modal reader of Partisan Review might have been.

In other ways, they are less public. They are more ideologically constrained than either their predecessors or the general population. There are few radical left-wingers, and fewer conservatives. Very many of them sit somewhere on the spectrum between hard libertarianism and moderate liberalism. These new intellectuals disagree on issues such as privacy and security, but agree on more, including basic values of toleration and willingness to let people live their lives as they will. At their best, they offer an open and friendly pragmatism; at their worst, a vision of the future that glosses over real politics, and dissolves the spikiness, argumentativeness, and contrariness of actual human beings into a flavorless celebration of superficial diversity.

Shakespeare The Auteur

Shakespeare In Company author Bart van Es argues that the Bard owes a good deal of his success to the Lord Chamberlain’s Men, which allowed him unprecedented dramatic and financial freedom:

[O]ne of the things that really separates Shakespeare from his contemporaries is that his plays are all owned by the company. That was a big change from how it was for him at the start of his career. The first of his plays to be published, Titus Andronicus, didn’t even mention his name on it, just the three acting companies who had performed it. But after he joined the Chamberlain’s Men, he was an asset holder. He would get paid for plays which were performed 10 years after he’d written them. No one else was doing that.

Before that, plays were often put together by a team of writers, and then rewritten and rewritten, a bit like the Hollywood model of having screenwriters and script doctors all chipping in. But Shakespeare became an auteur, in film terms. He was a sort of Woody Allen figure. He wrote the plays, he had control over them, the same actors came back again and again. And he was clearly much more famous than any other playwright of his time.

The Reason He Wore Black

Writing on the 10th anniversary of Johnny Cash’s death, Michael Stewart Foley praises the singer’s “politics of experience and empathy, a politics that transcended political labels and polarization”:

Cash did not shy away from going on record (vinyl or otherwise) with his feelings about the Vietnam War. Like many veterans (and other country-music stars such as Merle Haggard), he continued to respect the authority of the president and, as such, pledged to support Richard Nixon’s efforts to end the war. But he also routinely pleaded for tolerance, most obviously in a song from the Man in Black LP: “Can you blame the voice of youth for asking, ‘What is truth?’”

For Cash, there was nothing inconsistent in these positions because he did not approach the war as a hawk or a dove, but from the perspective of a younger brother to a boy who had died young (Cash’s older brother, Jack, died in a table-saw accident when Cash was 12). The death in Vietnam of Jimmy Howard, son of country singer Jan Howard, hit Cash especially hard and probably prompted him to write the 1970 song, “Route 1, Box 144”—the story of a “good boy” killed in Vietnam, leaving a wife and baby. The focus of the song is not on the wider politics of the war, but on the kind of familial suffering to which Cash could relate. The following year, when he wrote “Man in Black,” he included the line about wearing black in mourning because “each week we lose a hundred fine young men.”

A Novel Take On Natural Selection

Reminding us that “[t]o affect species-wide change, a trait essentially has to help you live or get laid,” Jennifer Vanderbes considers the evolutionary purpose of great fiction:

Among the many things that set humans apart from other animals is our capacity for counterfactual thinking. At its most basic level, this means we can hypothesize what might happen if we run out of milk; in its most elaborate form—we get War and Peace. Stories, then, are complex counterfactual explorations of possible outcomes: What would happen if I killed my landlady? What would happen if I had an affair with Count Vronsky? How do I avoid a water buffalo? According to Denis Dutton, these “low-cost, low-risk” surrogate experiences build up our knowledge stores and help us adapt to new situations. (“Mirror neuron” research indicates that our brains process lived and read experiences almost identically.) A good “cautionary tale,” for example, might help us avert disaster. Stories can also provide useful historical, scientific, cultural and geographical information. Bruce Chatwin’s Songlines illustrates this on two tiers: In armchair-travel fashion, the book acquaints readers with the Australian Outback, while simultaneously describing how Aboriginals sang stories walking at a specific pace so that geographical markers within the story would guide their journey.

In addition to travelogues, stories also offer nuanced thought maps. An imaginative foray into another person’s mind can foster both empathy and self-awareness. This heightened emotional intelligence might, in turn, prove useful when forming friendships, sniffing out duplicity, or partaking in the elaborate psychological dance of courtship…

Christopher Jobson explains how the incredible video was made:

Last Thanksgiving, [filmmaker Anthony Cerniello] traveled to his friend Danielle’s family reunion and with still photographer Keith Sirchio shot portraits of her youngest cousins through to her oldest relatives with a Hasselblad medium format camera. Then began the process of scanning each photo with a drum scanner at the U.N. in New York, at which point he carefully edited the photos to select the family members that had the most similar bone structure. Next he brought on animators Nathan Meier and Edmund Earle who worked in After Effects and 3D Studio Max to morph and animate the still photos to make them lifelike as possible. Finally, Nuke (a kind of 3D visual effects software) artist George Cuddy was brought on to smooth out some small details like the eyes and hair.

Who’s Happier, Extroverts Or Introverts?

Apparently the former:

Perhaps one of the most important (and consistent) findings in E/I research is that extroverts are overall happier than introverts, and this increased happiness lasts for decades. Scientists have struggled to pinpoint the cause of extroverts’ happiness, though they are certainly not without ideas.

Researchers have proposed that extroverts may feel greater happiness than introverts because they are more sensitive to rewarding social situations. On the other hand, others have suggested that extroverts are happier because they engage in more social activities. Some scientists think that extroverts’ perpetual happiness stems from their greater mood regulation abilities. Or maybe they’re happy because they hold on tightly to all of those good memories.

At the same time, however, scientists have questioned whether extroverts really are happier, or if they’re just more declarative with their feelings. There’s also the issue of how, exactly, you define and measure “happiness.” Whatever the case, extroverts and introverts likely benefit from different happiness increasing strategies, given the inherent differences in the personality types.

Growing Old, Growing Human

Our species didn’t come into its own until we started living past the age of 30:

Anthropologist Rachel Caspari of Central Michigan University used teeth to identify the ratio of old to young people in Australopithecenes from 3 million to 1.5 million years ago, early Homo species from 2 million to 500,000 years ago, and Neanderthals from 130,000 years ago. Old people – old here means older than 30 (sorry) – were a vanishingly small part of the population. When she looked at modern humans from the Upper Paleolithic, about 30,000 years ago, though, she found the ratio reversed – there were twice as many adults who died after age 30 as those who died young.

The Upper Paleolithic is also when modern humans really started flourishing. That’s one of the times the population boomed and humans created complex art, used symbols, and colonized even inhospitable environments. … [O]nce humans found a way to keep old people around, everything changed. Old people are repositories of information, Caspari says. They know about the natural world, how to handle rare disasters, how to perform complicated skills, who is related to whom, where the food and caves and enemies are. They maintain and build intricate social networks. A lot of skills that allowed humans to take over the world take a lot of time and training to master, and they wouldn’t have been perfected or passed along without old people.

What Works Against Terrorism?

We haven’t a clue:

The Afghanistan war has cost $657.5 billion so far, we spend $17.2 billion in classified funds a year fighting terrorism through the intelligence community, and the Department of Homeland Security spent another $47.4 billion last year. And we have very little idea whether any of it is preventing terrorist attacks. …

It’s scandalous that we spend billions every year on counterterrorism but barely spend any effort on evaluating whether what we’re doing works. The federal government is showing slightly more interest than it once did. “We’re lucky because there’s a criminologist in DHS who helps the partnership along a bit,” [criminologist Cynthia] Lum tells me. But the scale of the efforts pales in comparison the efforts to build evidence on health, education, social welfare, or crime policy. That has to change.

And I think that’s underlying public discontent with respect to Syria. The cost-benefit analysis of the last decade makes – and should make – anyone shudder at the thought of anything like those policies being continued. Obama, for the most part, has avoided them. But the huge budgets for the NSA and DHS and the post-9/11 Pentagon have no serious accounting for them in terms of benefits to the American people. I suspect Washington’s political class need to address this question – and answer it thoroughly – before they will ever get backing for war again.
