“Outward show is a wonderful perverter of the reason”*…
Humans have long hungered for a short-hand to help in understanding and managing other humans. From phrenology to the Myers-Briggs Test, we’ve tried dozens of short-cuts… and tended to find that at best they weren’t actually very helpful; at worst, they were reinforcing of stereotypes that were inaccurate, and so led to results that were unfair and ineffective. Still, the quest continues– these days powered by artificial intelligence. What could go wrong?…
Could a program detect potential terrorists by reading their facial expressions and behavior? This was the hypothesis put to the test by the US Transportation Security Administration (TSA) in 2003, as it began testing a new surveillance program called the Screening of Passengers by Observation Techniques program, or Spot for short.
While developing the program, they consulted Paul Ekman, emeritus professor of psychology at the University of California, San Francisco. Decades earlier, Ekman had developed a method to identify minute facial expressions and map them on to corresponding emotions. This method was used to train “behavior detection officers” to scan faces for signs of deception.
But when the program was rolled out in 2007, it was beset with problems. Officers were referring passengers for interrogation more or less at random, and the small number of arrests that came about were on charges unrelated to terrorism. Even more concerning was the fact that the program was allegedly used to justify racial profiling.
Ekman tried to distance himself from Spot, claiming his method was being misapplied. But others suggested that the program’s failure was due to an outdated scientific theory that underpinned Ekman’s method; namely, that emotions can be deduced objectively through analysis of the face.
In recent years, technology companies have started using Ekman’s method to train algorithms to detect emotion from facial expressions. Some developers claim that automatic emotion detection systems will not only be better than humans at discovering true emotions by analyzing the face, but that these algorithms will become attuned to our innermost feelings, vastly improving interaction with our devices.
But many experts studying the science of emotion are concerned that these algorithms will fail once again, making high-stakes decisions about our lives based on faulty science…
“Emotion detection” has grown from a research project to a $20bn industry; learn more about why that’s a cause for concern: “Don’t look now: why you should be worried about machines reading your emotions.”

As we insist on the individual, we might recall that it was on this date in 1989 that Tim Berners-Lee submitted a proposal to CERN for developing a new way of linking and sharing information over the Internet.
It was the first time Berners-Lee proposed a system that would ultimately become the World Wide Web; but his proposal was basically a relatively vague request to research the details and feasibility of such a system. He later submitted a proposal on November 12, 1990 that much more directly detailed the actual implementation of the World Wide Web.
“The city’s full of people who you just see around”*…

Much of the history of the city—its built forms and its politics, the urban experience, and the characteristic moral ambivalence that cities arouse—can be written as a tension between the visible and the invisible. What and who gets seen? By whom? Who interprets the city’s meaning? What should remain unseen?
Rulers of cities have always had an interest in visibility, both in representing their power and in controlling people by seeing them. The earliest cities emerged out of the symbiosis of religion and political power, and the temple and the citadel gave early urbanism its most visible elements…

As we wonder, with Juvenal (and Alan Moore), who watches the watchmen, we might recall that it was on this date in 1752 that Benjamin Franklin and his son tested the relationship between electricity and lightning by flying a kite in a thunder storm. Franklin was attempting a (safer) variation on a set of French investigations about which he’d read. The French had connected lightning rods to a Leyden jar, but one of their experiments electrocuted the investigator. Franklin– who may have been a wastrel, but was no fool– used a kite; the increased height/distance from the strike reduces the risk of electrocution. (But it doesn’t eliminate it: Franklin’s experiment is now illegal in many states.)
In fact, (other) French experiments had successfully demonstrated the electrical properties of lightning a month before; but word had not yet reached Philadelphia.

“Why do people respect the package rather than the man?”*…
Alphonse Bertillon’s Tableau synoptic des traits physionomiques was essentially a cheat sheet to help police clerks put into practice his pioneering method for classifying and archiving the images (and accompanying details) of repeat offenders, a system known as bertillonage. Beginning his career as a records clerk in the Parisian police department, Bertillon, the child of two statisticians and endowed with an obsessive love of order, soon became exasperated with the chaos of the files on offenders. The problem was particularly acute when it came to identifying offenders as repeat offenders (recidivists), given that the person in question could simply provide a false name. Before Bertillon, to find the files of the accused (or if there was even one already existing) the police would have to sift through the notorious “rogues’ gallery”, a disorganised mess of photographic portraits of past offenders, and hope for a visual match.
Bertillon’s solution was to develop a rigorous system of classification, or “signalment”, to help organise these photographs. This involved — in addition to taking simple measurements of the head, body, and extremities — breaking down the criminal’s physiognomy into discrete and classifiable elements (the curl of ear, fold of brow, inclination of chin). What in other contexts might be the much loved (or reviled) expressions of a personality, in Bertillon’s world become simply units of information. Taking a note of these, as well as individual markings such as scars or tattoos, and personality characteristics, Bertillon could produce a composite formula that could then be tied to a photographic portrait and name, all displayed on a single card, a portrait parlé (a speaking portrait). These cards were then systematically archived and cross-indexed, to make the task of linking a reticent offender with a possible criminal past, infinitely easier. Put into practise in 1883, the system was hugely effective and was soon adopted by police forces across the channel, before spreading throughout Europe and the Americas, (though without Bertillon’s obsessive eye overseeing proceedings, its foreign adventures were not a complete success).
Key to the whole endeavour, of course, was the new exactitude of representation afforded by photography, though this was still an exactitude limited to a particular moment. Over time faces change, a fact which rendered Bertillon’s system less than perfect. With the call for an identifier more fixed than the measurements of an inevitably changing face, and a system less complex, bertillonage was eventually, by the beginning of the 20th century, supplanted by the new kid on the forensic science block — fingerprinting…

As we try on a Privacy Visor, we might recall that it was on this date in 1814 that London suffered “The Great Beer Flood Disaster” when the metal bands on an immense vat at Meux’s Horse Shoe Brewery snapped, releasing a tidal wave of 3,555 barrels of Porter (571 tons– more than 1 million pints), which swept away the brewery walls, flooded nearby basements, and collapsed several adjacent tenements. While there were reports of over twenty fatalities resulting from poisoning by the porter fumes or alcohol coma, it appears that the death toll was 8, and those from the destruction caused by the huge wave of beer in the structures surrounding the brewery.
(The U.S. had its own vat mishap in 1919, when a Boston molasses plant suffered similarly-burst bands, creating a heavy wave of molasses moving at a speed of an estimated 35 mph; it killed 21 and injured 150.)

While public debate about the license reading technology has centered on how police should use it, business has eagerly adopted the $10,000 to $17,000 scanners with remarkably few limits… But the most significant impact is far bigger than locating cars whose owners have defaulted on loans: It is the growing database of snapshots showing where Americans were at specific times, information that everyone from private detectives to insurers are willing to pay for… Unlike law enforcement agencies, which often have policies to purge their computers of license records after a certain period of time, the data brokers are under no such obligation, meaning their databases grow and gain value over time as a way to track individuals’ movements and whereabouts…

As we reconsider public transit, we might recall that it was on this date in 1818 that Mary Shelley’s Frankenstein was published. Shelley had begun writing the story two years earlier, when she was 18 and on vacation near Geneva with her husband (the poet Percy) and their friend Lord Byron. The house party set itself the task of each writing a gothic story; only Mary finished hers. The first edition was published anonymously; Shelley was first publicly identified as the author on the title page of the 1823 second edition.
The work has, as Brian Aldiss argues, a strong claim to being the first true science fiction novel. As the sub-title– “The Modern Prometheus”– suggests (and like all great sci fi), it treats the philosophical, cultural, and psychological ramifications of scientific and technological progress.

The world now has access to a list of words and phrases that the U.S. Department of Homeland Security uses to monitor social networks and news article comments for terrorism and general threats against the country.
The list was part of a 39-page “2011 Analyst’s Desktop Binder” document that was released due to a Freedom of Information Act request by privacy watchdog organization Electronic Privacy Information Center. The list contains references to all the related governmental agencies, obvious references to threats (attack, nuclear threat, etc.) and then some pretty generic words like pork, cloud, electric, port, dock, and many others…

As we reckon that we’ve already been fingered, we might send tuneful birthday wishes to Woodrow Wilson “Woody” Guthrie; he was born on this date in 1912. Guthrie traveled with migrant workers from Oklahoma to California and learned their traditional folk and blues songs. Many of his own songs are about his experiences in the Dust Bowl era during the Great Depression– and earned him the nickname, “Dust Bowl Troubadour.”
‘This Land is Your Land (in D)’By Woody Guthrie
CHORUS: This land is your land, this land is my land
From California to the New York island
From the Redwood forest to the Gulf Stream waters
This land was made for you and meCANADIAN CHORUS:
This land is your land, this land is my land
From Bonavista to Vancouver Island

This land is your land, this land is my land
From California to Sanibel Island
From the Redwood forest to the Gulf Stream waters
This land was made for you and meAs I was walking that ribbon of highway
I saw above me that endless skyway
I saw below me that golden valley
This land was made for you and meI roamed and rambled and followed my footsteps
O’er the sparkling sands of her diamond deserts
While all around me, a voice was saying
This land was made for you and meWhen the sun came shining and I was strolling
And the wheat fields waving and the dust clouds rolling
As the fog was lifting, a voice was chanting
This land was made for you and meAs I went walking, I saw a sign there
On the sign it said NO TRESPASSING
But on the other side it didn’t say nothing
That side was made for you and me!In the squares of the city, in the shadow of the steeple
In the relief office, I seen my people;
As they stood there hungry I stood there asking,
Is this land made for you and me?Nobody living can ever stop me
As I go walking that freedom highway
Nobody living can make me turn back
This land was made for you and me
Ho, ho… Got ya!…
The most widely recognized and embraced folklore by young children is Santa Claus – a plump, white-bearded and red-suited gentlemen who delivers presents to ‘good’ children at Christmas time. To young children, the arrival of Santa Claus on Christmas Eve is an event filled with joy. Indeed, it is the culmination of days filled with great anticipation and expectation.
The Santa Claus Detector is therefore an object of the present invention to provide a children’s device capable of providing selective illumination to signal the arrival of Santa Claus. This is particularly important to young children, providing reassurance that the child’s good behavior has in fact been rewarded by Santa Claus.

As we remember that letters to the North Pole take an extra 19 cents in postage, we might also recall that it was on this date in 1928, in Clinton, Iowa, that the clip-on tie was invented.
Now you don’t…
Adam Harvey is a graduate student in NYU’s fabled ITP Program who is putting his considerable talents to work in the service of privacy. His thesis work, CV Dazzle, is aiming at finding ways to confound computer facial recognition systems. As The Register reports:
Concerned about the proliferation of face recognition systems in public places, a grad student in New York is developing privacy-enhancing hacks designed to thwart the futuristic surveillance technology.
Using off-the-shelf makeup and accessories such as glasses, veils, and artificial hair, Adam Harvey’s master’s thesis combines hipster fashion aesthetics with hardcore reverse engineering of face detection software. The goal: to give individuals a low-cost and visually stimulating means to prevent their likenesses from being detected and cataloged by face-recognition monitors.
“The number of sensors that are going into the public spaces has been increasing,” said Harvey, a student in New York University’s interactive telecommunications program. “There’s a lot of work to be done to catch up to where cameras are going because there have been so many advances in the last few years.”
Although still in its adolescence, face recognition technology is quickly being adopted by governments and corporations to identify individuals whose images are captured by surveillance cameras. At the 2001 Super Bowl, for instance, officials digitized the faces of everyone entering Raymond James Stadium in Tampa, Florida and compared the results against photographic lists of known malefactors.
…
But Harvey has discovered that face detection can often be thrown off by using makeup to alter the contrasts the technology looks for. For example, dark patterns applied around eyes and cheek bones, as in the image below, are one such possibility.

Harvey asks, “How can hats, sunglasses, makeup, earrings, necklaces or other accessories be modified to become functional and decorative?”; and he explains “The aim of my thesis is not to aid criminals, but since artists sometimes look like criminals and vice versa, it is important to protect individual privacy for everyone.”
As we rework our pick-up lines, we might take inspiration from the memory that it was on this date in 1810 that Beethoven wrote Bagatelle No. 25 in A minor (WoO 59 and Bia 515) for solo piano– better known as “Für Elise” (click to hear).
Some scholars have suggested that “Elise” was Beethoven’s mistress; but others have suggested that the discoverer of the piece, Ludwig Nohl, may have transcribed the title incorrectly and the original work may have been named “Für Therese”– Therese being Therese Malfatti von Rohrenbach zu Dezza, a friend and student of Beethoven’s to whom he proposed in 1810… not actually so encouraging as an example, since though she turned him down to marry the Austrian nobleman and state official Wilhelm von Droßdik… still, a beautiful piece…
