Cyberwars: FBIs Facial Recognition Database

facial_rec1This past summer, the FBI was compelled to release information about the operational facial recognition database they working on. As part of its Next Generation Identification (NGI) program, this database is part of the FBIs efforts to build a “bigger, faster and better” means of biometric identification. Earlier this month, the FBI announced that the system is now working at “full operational capability”, and many people are worried…

To break it down, the NGI database is made up of millions of stored mugshots and other photos, which are then used when analyzing footage taken by CCTV feeds or other cameras around the country. The full deployment of the program comes three months after James Comey, the bureau’s director, announced that the agency was “piloting the use of mug shots” alongside the bureau’s other databases, in order to catch wanted criminals.

FBI_NGI_Slide_WideDesigned to replace the bureau’s aging fingerprint database, the NGI is different in that it is designed to be multimodal. This means that it will link multiple forms of biometric data to biographical information such as name, address,  ID number, age and ethnicity. It’s currently focused on fingerprint and facial records, but it will also be capable of holding iris scans and palm prints, with the possibility of added voice recognition and gate analysis (i.e. how people walk).

As the FBI said in a statement on Monday, Sept. 15th, the NGI, combined with fingerprint database:

[W]ill provide the nation’s law enforcement community with an investigative tool that provides an image-searching capability of photographs associated with criminal identities.

Naturally, the worries that this database will be another step towards “Big Brother” monitoring. However, what is equally (if not more) worrisome is the fact that the details of the program are only a matter of public record thanks to a lawsuit filed by the Electronic Frontier Foundation. The lawsuit was issued in June of 2013, wherein the EFF compelled the FBI to produce records in accordance Freedom of Information Act to detail the program and its face-recognition components.

facial_recCiting the FBI documents, the EFF claims that the facial recognition technology is not very reliable and that the way the database returns results is fundamentally flawed, as well as pointing out that it will indiscriminately combine the details of both criminals and non-criminals. Based on their own interpretation, they claim it could fail 20 percent of the time, which could lead to innocent persons becoming the subject of police investigations.

Nevertheless, the bureau remains confident that the system will simplify and enhance law enforcement both locally and federally. As they said of the program when it was first announced back in 2011:

The NGI system has introduced enhanced automated fingerprint and latent search capabilities, mobile fingerprint identification, and electronic image storage, all while adding enhanced processing speed and automation for electronic exchange of fingerprints to more than 18,000 law enforcement agencies and other authorized criminal justice partners 24 hours a day, 365 days a year.

fingerprint_databaseIn 2012, the NGI database already contained 13.6 million images (of seven to eight million individuals) and by mid-2013, it had 16 million images. We now know it aims to have 52 million facial records in its system by next year, and those will include some regular citizens. This is another source of concern for the EFF and civil liberties advocates, which is the estimated 4.3 million images taken for non-criminal purposes.

Whenever someone applies for a job that requires a background check, they are required to submit fingerprint records. These records are then entered into federal databases. Right now, the FBI’s fingerprint database contains around 70 million criminal profiles, and 34 million non-criminal records. With the NGI database now up and running, photographs can be submitted by employers and other sources along with fingerprints, which puts non-criminals on file.

FBI-facial-recognitionThe database, while maintained by the FBI, can be searched by law enforcement at all levels. According to Jennifer Lynch, the EFF attorney behind the lawsuit:

Your image would be searched every time there is a criminal investigation. The problem with that is the face recognition is still not 100 percent accurate.” This means that the system is liable to make mismatches with data. If a camera catches a criminal’s face and that is compared to images in the database, there’s no guarantee that it will pop up an accurate result. 

What’s more, when the database is searched it does not return a completely positive result; but instead provides the top hits, ranked by probability of match. So if your face just happens to be similar to a snapshot of a criminal caught in CCTV footage, you may become a suspect in that case. Combined with other forms of biometric readers and scanners, it is part of a general trend where privacy is shrinking and public spaces are increasingly permeated by digital surveillance.

internet-of-things-2This sort of data exchange and on-the-ground scanning will be made possible by – and is one of the explicit aims of – FirstNet, the nationwide broadband network for law enforcement and first responders, colloquially referred to by some as the “internet of cops”. Much like all things pertaining the expansion of the internet into the “internet of things”, this sort of growth has the capacity to affect privacy and become invasive as well as connective.

As always, fears of an “Orwellian” situation can be allayed by reminding people that the best defense is public access to the information – to know what is taking place and how it works. While there are doubts as to the efficacy of the NGI database and the potential for harm, the fact that we know about its inner workings and limitations could serve as a legal defense wherever a potentially innocent person is targeted by it.

And of course, as the issue of domestic surveillance grows, there are also countless efforts being put forth by “Little Brother” to protect privacy and resist identification. The internet revolution cuts both ways, and ensures that everyone registered in the torrential data stream has a degree of input. Fight the power! Peace out!

News from Space: Chang’e-3’s Landing and 1st Panorama

Change-3-landing-site_1_ken-kremer-580x344China accomplished a rather major technological and scientific feat recently with the recent soft landing of its Chang’e-3 robotic spacecraft on Dec.14th. This was the nation’s first attempt at landing a spacecraft on an extra-terrestrial body, and firmly established them as a competitor in the ongoing space race. What’s more, the event has been followed by a slew of fascinating and intriguing pictures.

The first were taken by the descent imaging camera aboard the Chang’e-3 lander, which began furiously snapping photos during the last minutes of the computer guided landing. The Chinese space agency then combined the photos to create a lovely compilation video, with the point of view rotated 180 degrees, to recreate what the descent looked like.

Change-3_lunar_landing_site-580x470The dramatic soft landing took place at 8:11 am EST (9:11 p.m Beijing local time) with the lander arriving at Mare Imbrium (Latin for “Sea of Rains”) – one of the larger craters in the Solar System that is between 3 and 4.5 billion years old. The precise landing coordinates were 44.1260°N and 19.5014°W – located below the Montes Recti mountain ridge.

The video begins by showing the Chang’e-3 lander approaching the Montes Recti mountain ridge. At an altitude of 15 km (9 miles), the Chang’e-3 carried out the rocket powered descent to the Moon’s surface by firing the landing thrusters starting at the altitude of 15 km (9 mi) for a soft landing targeted to a preselected area in Mare Imbrium.

chang'e3_landingThe vehicles thrusters then fired to pivot the lander towards the surface at about the 2:40 minute mark when it was at an altitude of roughly 3 km (1.8 miles). The powered descent was autonomous, preprogrammed and controlled by the probe itself, not by mission controllers on Earth stationed at the Beijing. Altogether, it took about 12 minutes to bring the lander onto the surface.

Roughly 7 hours later, on Sunday, Dec. 15 at 4:35 a.m. Beijing local time, China’s first ever lunar rover ‘Yutu’ (or Jade Rabbit) rolled down a pair of ramps and onto the Moon’s soil. The six wheeled ‘Yutu’ rover drove straight off the ramps and sped right into the history books as it left a noticeably deep pair of tire tracks behind in the loose lunar dirt. This too was captured by the lander’s camera and broadcast on China’s state run CCTV.

chang'e3_egressThe next bundle of footage came from the rover itself, as the Jade Rabbit took in its inaugural photographs of the landing site in Mare Imbrium. The photos were released by Chinese state TV on Dec. 15th, not long after the rover disembarked from the lander, and were then pieced together to form the lander’s first panoramic view of the lunar surface.

Marco Di Lorenzo and Ken Kremer – an amateur photo-astronomer and a science journalist who have composed panoramas from the Curiosity mission in the past – also composed the images together to create a series of mosaics. A sample of the 1st panorama is pictured below, with the Yutu rover in the center and tire tracks off to the left.. Click here to the see the full-size image.

Change-3-1st-Pano_1b_Ken-Kremer--580x203The individual images were taken by three cameras positioned around the robotic lander and captured the stark lunar terrain surrounding the spacecraft. The panoramic view shows ‘Yutu’ and its wheel tracks cutting a semi circular path at least several centimeters deep into the loose lunar regolith at the landing site at Mare Imbrium, located near the Bay of Rainbows.

Liu Enhai, Designer in Chief, Chang’E-3 Probe System, has this say about the images in a recent CCTV interview:

This picture is made of 60 pictures taken 3 times by the rover. The rover used three angles: vertical, 15 degrees tilted up, and 15 degrees down…so that we get an even farther view

chang'e3_portraitThe 140 kilogram Yutu rover then turned around so that the lander and rover could obtain their first portraits of one another. The first is visible above, showing the Jade Rabbit rover (in better resolution), with the image of the Chang’e 3 lander below. Liu Jianjun, Deputy Chief Designer of the Chang’E-3 Ground System, was also interviewed by CCTV, and had this to about that part of the mission:

The rover reached the point of X after it went down from the lander, then it established contact with the ground. Then it went to point A, where the rover and lander took pictures of each other. Then it reached point B, where it’s standing now.

These are just the first of what is expected to be a torrent of pictures produced by the rover, which according to Chinese officials, will spend the next year conducting in-situ exploration at the landing site. Beyond that, the rover will use its instruments to survey the moon’s geological structure and composition on a minimum three month mission to locate the moon’s natural resources for use by future missions.

chang'e3_lander_portIn addition to accomplishing a great scientific feat, China has now joined a very exclusive club, being only one of three nations that has successfully conducted a soft landing on the Moon. The United States was the first, reaching the Moon with its Apollo 11 mission on July 20th, 1969. The Soviet Union followed less than a decade later, having reached the Moon with its unmanned Lunik 24 spacecraft in 1976.

And now, almost forty years later, the space race is joined by one of the world’s emerging super powers. Soon, we can expect the European Space Agency, India, Pakistan, and possibly Iran to be reaching the Moon as well. And by that time, its likely the spaceships will be carrying colonists. Hopefully we’ll have some infrastructure set up to receive them!

In the meantime, be sure to check out the Chang’e 3 descent video, and stay tuned for more updates from the Jade Rabbit and it begins its exploration of the Lunar surface.
