Amidst the excitement for the arrival of Google Glass, some people are worried

Google Glass is expected to arrive later this year for less than $1500. Not without controversy, though. Some experts, including the Canadian cyborg Steve Mann, believe the augmented reality eyewear will cause strain and damage to the eyes, especially to children. The heads-up display may also distract the user from what’s happening around him.

More importantly, there are big privacy concerns that we have to face with Google Glass. Wearers can take photos and record images of people, things, and places around them. The issue is not the user experience of the one wearing Google Glass but the user experience of the people around someone wearing the eyewear. Aside from the possible annoyance of talking to someone who is distracted by other things, it will be hard to know if that person is taking a picture or video of you.

Mark Hurst made a good explanation of why this new technology can trigger an Orwellian nightmare.

First, take the video feeds from every Google Glass headset, worn by users worldwide. Regardless of whether video is only recorded temporarily, as in the first version of Glass, or always-on, as is certainly possible in future versions, the video all streams into Google’s own cloud of servers. Now add in facial recognition and the identity database that Google is building within Google Plus (with an emphasis on people’s accurate, real-world names): Google’s servers can process video files, at their leisure, to attempt identification on every person appearing in every video…Finally, consider the speech-to-text software that Google already employs, both in its servers and on the Glass devices themselves. Any audio in a video could, technically speaking, be converted to text, tagged to the individual who spoke it, and made fully searchable within Google’s search index.

Stop the Cyborgs wants to ban Google Glass

Cord Jefferson of Gizmodo, meanwhile, believes Google Glass will enable men to take creepshots of women’s body parts more surreptitiously.

Months before the release of Google Glass, The 5 Point cafe/dive bar has banned the use of Google Glass inside their premises. Similarly, West Virginia lawmakers have introduced a bill that will make the use of Google Glass during driving illegal, as an extension of the no-texting-while-driving law. Also, a site called “Stop the Cyborgs” aims to stop a future in which privacy is impossible. The group opposes Google Glass in particular.

At the other side of the fence, many people think Google Glass looks dorky. Some people have also expressed intense hatred for the device due to the privacy concerns, to the point of threatening violence to future users. Wearers can therefore expect a wide range of negative reaction, from being stereotyped as nerdy or douche (for invading privacy) to antagonism and discrimation in some establishments, to outright violence. That is, of course, until Google Glass becomes mainstream and competitors get in on the bandwagon.

You can soon log your everyday life through the Memoto wearable camera

Late last year, the Sweden-based tech startup Memoto AB launched their camera in Kickstarter. It was a huge hit and has earned ten times the goal.

The Memoto camera is a lifelogging device — a tiny, wearable camera that automatically takes a 5MP geotagged image every 30 seconds. The photo’s orientation is also recorded so that the app can show the image upright no matter how you are wearing the camera. The Memoto camera is only 36mm x 36mm x 9mm big and does not have any buttons. Just clip it on your clothes and go! Lay it flat or put it in a dark place to turn it off.

Memoto lifelogging cameras

When I first heard about the Memoto camera, two things came to mind: privacy concerns and the possible deluge of inane pictures of narcissistic people online. But it will really be sweet to have such an automatic and unobtrusive camera during travel or special events. Reliving the whole thing without having to dampen the original moment’s enjoyment by having to snap pictures and take videos is certainly appealing.

Of course, for many people, the appeal lies in the details — the little things that we don’t take much notice of or bother to take pictures of. With this camera, no more blurry recollections of things, places, and people we’ve encountered.

The built-in battery of the Memoto camera lasts for two days before having to be recharged. When the camera is connected to the computer through a micro-USB port, the battery is recharged while the photos (up to 4000 photos) are automatically uploaded to Memoto’s servers.

The Memoto app organizes the images into groups of “moments” on a timeline. The app uses the images’ metadata such as time, place, and light; this enables the user to search for specific pictures. The photos are in private mode by default but can be shared to several social media services if the owner wants to. The app works for both iPhone and Android.

The company offers its customers infinite photo storage at a flat monthly fee. The images transferred to Memoto’s cloud servers are stored encrypted.

The Kickstarter project has ended but interested buyers can pre-order the camera at the Memoto Web site. The company offers free shipping worldwide for preorders (estimated delivery: April 2013), with 1 year storage included. The cameras are available in three colors: Memoto Orange, Graphite Gray, and Arctic White.

Short Film: Ninety Seconds, a review

poster of the short film Ninety Seconds

The short film Ninety Seconds is a sci-fi thriller directed by Gerard Lough. It is set in the near future. The exact year is not given, but can be intuited to be 2017 or later. The film opens with a quote from George Orwell’s 1984: “The instrument could be dimmed, but there was no way of shutting it off completely.”

In this universe, there are private detectives, called “techs”, who have access to surveillance equipment similar to those used by intelligence agencies. People with enough money can hire these techs to invade other people’s privacy. The title Ninety Seconds refers to the average length of useful or incriminating evidence the lead character gets from hours of surveillance footage.

Mark (Andrew Norry) and his assistant Ralfi (Claire J. Blennerhassett) are techs hired by Mr. Philips (Michael Parle) to spy on the beautiful burlesque dancer Elly (Emma Eliza Regan). This get complicated when Mark develops a personal interest on Elly and begins to feel that other people are following him.

Here’s the complete short film (27 minutes long):

Hide from Big Brother using a privacy visor and stealth hoodie

Isao Echizen, an associate professor in The National Institute of Informatics in Tokyo, Japan and Seiichi Gohshi, a professor at Kogakuin University, have developed a visor that can protect the wearer from invasion of privacy caused by unauthorized facial recognition systems. The glasses work by adding noise to the images using a near-infrared light source that affects cameras but not ordinary human vision. When the near-infrared LED in the privacy visor is not lit, facial detection is not affected (Figure a) but when the LED is lit, noise is added to the image and face recognition is prevented (Figure b).

According to Slate, Echizen has received offers from companies that want to commercialize the visors and that they are working on a better version — one that does not need an external power supply — which may be as cheap as $1 per unit.

privacy visor is a kind of glasses that protects against automated face recognition

With the privacy visor and the CV Dazzle project, privacy buffs can probably escape the widening presence of facial recognition systems and software, such as in the EyeSee mannequins. Let’s just hope that these privacy options will evolve into less conspicuous ones that will allow the users to blend in.

In the meantime, the New York artist Adam Harvey has come up with clothing items that can thwart heat signature-sensing cameras. His line of stealth wear fashion includes:

  • anti-drone burqa, hoodie, and scarf: for blocking thermal imaging
  • XX-shirt: a X-ray shielding print that protects the wearer’s heart from X-ray radiation
  • Off Pocket: a phone accessory that blocks a phone’s signal

Stealth Wear: counter surveillance fashion line by Adam Harvey

These counter surveillance items are available for sale at Primitive London.

CV Dazzle: how to block automated face detection

In my previous post, I discussed the EyeSee mannequins that profile store customers by using facial detection. The world seems to be going towards facial recognition becoming a more prevalent technology. A lot of privacy advocates are understandably bothered by this trend. If you’re one of these people, you may want to check out the CV Dazzle project. CV stands for “computer vision” while Dazzle is a form of ship camouflage used during WWI to confuse the enemy and cause him to miss his shot when firing.

Similarly, CV Dazzle uses makeup and hairstyling to prevent automated face detection and to protect privacy. It does not include the use of sunglasses (which some face detection systems have already accounted for), masks (which may be illegal) or hoods (which are obvious).

Some quick tips: partially obscure the nose bridge and the eye area.

CV Dazzle anti-face detection

The current CV Dazzle designs are inspired by tribal paint and high-fashion aesthetics seen in clubs.

If you’re fascinated with this project, Adam Harvey (the guy behind CV Dazzle) is accepting donations and talented contributors.

They are spying on you while you eat or shop

Almax, an Italian company, is selling “EyeSee” mannequins — dummies that use facial recognition software to record people’s age, gender, race, and the length of time they spent around the mannequins. The information is then used to improve the store’s layouts, window displays, and promotions to entice customers to buy.

mannequinsWhile overhead cameras have been in use in retail stores for decades, the EyeSee mannequins have hidden cameras that monitor passersby at eye-level. They use the facial recognition technology originally used to identify criminals at airports. But these dummies don’t come cheap. Each one costs EUR 4000 (USD 5130).

According to Bloomberg, several dozen EyeSee mannequins have been sold and are currently in use by five luxury companies in three European countries and the United States. Almax CEO Max Cantanese declined to disclose their clients. Benetton buys mannequins from Almax but denied using the EyeSee system. Burberry and Nordstrom likewise said that they don’t use the mannequins.

Privacy advocates are of course not happy with this technology. Some believe that profiling customers is illegal or at least unethical. Almax sees no privacy issues, however, since the EyeSee does not store images or biometric data.

Soon, the EyeSee mannequins may enable the retailers to eavesdrop on what the customers are saying about the products on display. Almax is adding microphones to the dummies and testing a technology that can recognize words.

On a related note, when I first saw this McDonald’s picture online, I thought it was a prank.

McDonald's in Sydney Airport records conversations

Apparently not. The picture was taken at the entrace of McDonald’s in Sydney Airport. It was posted in Twitter by David Litchfield, a researcher working for the security firm Accuvant.

“Your conversations will be audio and video recorded for quality assurance purposes.”

Hmm, some yummy fast food or privacy? Tough choices! What to choose? What to choose?
