Coalition Urges Supreme Court to Block Government Abuse of Surveillance Technology


Washington, D.C. – The principal inventor of the Global Positioning System (GPS) and other leading technologists have joined the Electronic Frontier Foundation (EFF) in urging the U.S Supreme Court to block the government from using GPS tracking without first getting a warrant, arguing that the massive collection of sensitive location data should require court oversight.

Roger L. Easton is considered the father of GPS as the principal inventor and developer of the Timation Satellite Navigation System at the Naval Research Laboratory. The current GPS is based on Timation, and its principles of operation are fundamentally identical. In an amicus brief filed with the Supreme Court Monday in United States v. Jones, EFF, Mr. Easton, along with other technology experts, pointed out the many ways in which GPS tracking is fundamentally different from and more invasive than other surveillance technologies the court has allowed before, and how law enforcement use of GPS without a warrant violates Americans’ reasonable expectations of privacy.

“This is the first case where the Supreme Court will consider automatic, persistent, passive location tracking by law enforcement,” said EFF Senior Staff Attorney Marcia Hofmann. “The government can use location information over time to learn where you go to church, what sort of doctors you go to, what meetings and activities you participate in, and much more. Police should not have blanket permission to install GPS devices and collect detailed information about people’s movements over time without court review.”

In Jones, FBI agents planted a GPS device on a car while it was on private property. Agents then used the GPS to track the position of the vehicle every ten seconds for a full month without obtaining a search warrant. An appeals court ruled that the surveillance was unconstitutional without a warrant, but the government appealed the decision.

“If police are allowed to plant GPS devices wherever they please, that’s essentially blanket permission for widespread, ongoing police surveillance without any court supervision,” said EFF Legal Director Cindy Cohn. “It’s not hard to see how that kind of leeway would be abused. We hope the Supreme Court takes a close look at how this technology works and act to protect the Fourth Amendment rights of Americans.”

The brief was authored by Andrew Pincus of Mayer Brown LLP and The Yale Law School Supreme Court Clinic. It was also signed by the Center for Democracy and Technology, Professor Matt Blaze of the University of Pennsylvania, Professor Andrew J. Blumberg of the University of Texas at Austin, and Professor Norman M. Sadeh of Carnegie Mellon University.

      Olá Karl, obrigado!
      O Site esteve fora do ar por cerca de um mês, só consegui colocá-lo de volta esses dias. Estou preparando um post (video, acabei perdendo a tradução que estava fazendo da música) sobre isso, e pretendo voltar a escrever semana que vem, enquanto isso fique à vontade para seguir via Twitter, mantenho por lá links para toda vez que posto aqui e alguns retweets sobre os mesmos temas. o endereço é @Cartrinet .
      Em breve volto a toda!

      Hi, i did answer to both mails again, basically i did answer that i can give no much help, and suggested you to research any needed changes @ Insanelymac and to use the latest chameleon . d00d has a nice compilation of fixes on your board, many others have similar interesting works with cham 2.1+
      good luck, i hope the mails arrive this time

  • Steve says:

    And so, I think you have blacklisted me? Anyway, answer me, if I had blacklisted, then I’ll leave you.

      Hi, i have received no answer from the mails I have sent you.
      This site domain was twice under watch, and has been made unaccessible trough DNS-Blacklists in many regions, i kind of got used to be “filtered”. It’s not a nice feeling, and I don’t apply it to others.
      Due to large automatized spam charge – and some isolated trolls from the past – which are not you, this site (the comments) blacklists any web address – and some words… this “filter” was created long ago to avoid what has been extensively explained at cartri net / blog /985 address.
      As it was also explained at the time, and in the e-mails, I am no longer interested (and have no good memory) about the subject of the M.E.B. project – the word abbreviated by “B.” is, I guess, also blacklisted (i goes… it was long ago).
      There are no trusted links for the already closed project files – as also explained above, I recommend you to look at Blackosx and d00d works (and many others) at Insanely Mac; and I don’t feel comfortable talking about all that messy times.
      I don’t really think that the project got to it’s objective (wake people up about corrupt licensing made by A. software – nothing else), since what was – at that time – an isolated absurd, is now nearer then ever from a market standard.
      Thanks for your interest on how I tried to change that, but my ways (the files) were never my means (changing the conscience about the unlawful market practice). The day it became clear that they were also not leading to these objectives, they lost their foundation and stopped existing.
      Again: this is not a subject i like to talk, as so, sorry for being brief.

  • Steve says:

    Hi! At last! It is 100% that our correspondence was filtered, ‘coz I get one answer from you for the first time to both mails and answered to you from both. And haven’t got any further answers. I think you haven’t got too (or not? ‘coz you wrote correct things directly related to my requests in my first mail answer.) I thought that mail correspondence is clear, but not.
    It’s ok, I’ll look forward for d00d works and all others.
    Too bad, too strange our world, especially capitalistic world with its’ strangeness… Hope you do not pay attention to this things.
    Respect from Russia. Steve aka Mstyslav.
