BitTorrent Sync creates private, peer-to-peer Dropbox, no cloud required | Ars Technica - 6 views

bittorrent p2p file-sync

shared by Paul Merrell on 28 Apr 13 - No Cached
  • BitTorrent today released folder syncing software that replicates files across multiple computers using the same peer-to-peer file sharing technology that powers BitTorrent clients. The free BitTorrent Sync application is labeled as being in the alpha stage, so it's not necessarily ready for prime-time, but it is publicly available for download and working as advertised on my home network. BitTorrent, Inc. (yes, there is a legitimate company behind BitTorrent) took to its blog to announce the move from a pre-alpha, private program to the publicly available alpha. Additions since the private alpha include one-way synchronization, one-time secrets for sharing files with a friend or colleague, and the ability to exclude specific files and directories.
  • BitTorrent Sync provides "unlimited, secure file-syncing," the company said. "You can use it for remote backup. Or, you can use it to transfer large folders of personal media between users and machines; editors and collaborators. It’s simple. It’s free. It’s the awesome power of P2P, applied to file-syncing." File transfers are encrypted, with private information never being stored on an external server or in the "cloud." "Since Sync is based on P2P and doesn’t require a pit-stop in the cloud, you can transfer files at the maximum speed supported by your network," BitTorrent said. "BitTorrent Sync is specifically designed to handle large files, so you can sync original, high quality, uncompressed files."
  • Paul Merrell on 28 Apr 13
     
    Direct P2P encrypted file syncing, no cloud intermediate, which should translate to far more secure exchange of files, with less opportunity for snooping by governments or others, than with cloud-based services.

    Hey Paul, is there an open source document management system that I could hook the BitTorrent Sync to?
  • Paul Merrell on 19 Jun 13
     
    More detail please. What do you want to do with the doc management system? Platform? Server-side or stand-alone? Industrial strength and highly configurable or lightweight and simple? What do you mean by "hook?" Not that I would be able to answer anyway. I really know very little about BitTorrent Sync. In fact, as far as I'd gone before your question was to look at the FAQ. It's linked from . But there's a link to a forum on the same page. Giving the first page a quick scan confirms that this really is alpha-state software. But that would probably be a better place to ask. (Just give them more specific information of what you'd like to do.) There are other projects out there working on getting around the surveillance problem. I2P is one that is a farther along than BitTorrent Sync and quite a bit more flexible. See . (But I haven't used it, so caveat emptor.)

    There is a great list of PRISM Proof software at http://prism-break.org/. Includes a link to I2P. I want to replace gmail though, but would like another Web based system since I need multi device access. Of course, I need to replace my Google Apps / Google Docs system. That's why I asked about a PRISM Proof sync-share-store DMS. My guess is that there are many users similarly seeking a PRISM Proof platform of communications, content and collaborative computing systems. BusinessIndiser.com is crushed with articles about Google struggling to squirm out from under the NSA PRISM boot-on-the-back-of-their-neck situation. As if blaming the NSA makes up for the dragnet that they consented/allowed/conceded to cover their entire platform. Perhaps we should be watching Germany? There must be tons of startup operations underway, all seeking to replace Google, Amazon, FaceBook, Microsoft, Skype and so many others. It's a great day for Libertyware :)

    Is the NSA involvement the "Kiss of Death"? Google seems to think so. I'm wondering what the impact would be if ZOHO were to announce a PRISM Proof productivity platform?
  • Paul Merrell on 19 Jun 13
     
    It is indeed. The E.U. has far more protective digital privacy rights than we do (none). If you're looking for a Dropbox replacement (you should be), for a cloud-based solution take a look at . Unlike Dropbox, all of the encryption/decryption happens on your local machine; Wuala never sees your files unencrypted. Dropbox folks have admitted that there's no technical barrier to them looking at your files. Their encrypt/decrypt operations are done in the cloud (if they actually bother) and they have the key. Which makes it more chilling that the PRISM docs Snowden link make reference to Dropbox being the next cloud service NSA plans to add to their collection. Wuala also is located (as are its servers) in Switzerland, which also has far stronger digital data privacy laws than the U.S. Plus the Swiss are well along the path to E.U. membership; they've ratified many of the E.U. treaties including the treaty on Human Rights, which as I recall is where the digital privacy sections are. I've begun to migrate from Dropbox to Wuala. It seems to be neck and neck with Dropbox on features and supported platforms, with the advantage of a far more secure approach and 5 GB free. But I'd also love to see more approaches akin to IP2 and Bittorrent Sync that provide the means to bypass the cloud. Don't depend on government to ensure digital privacy, route around the government voyeurs. Hmmm ... I wonder if the NSA has the computer capacity to handle millions of people switching to encrypted communication? :-) Thanks for the link to the software list.
  • Paul Merrell on 19 Jun 13
     
    Re: Google. I don't know if it's the 'kiss of death" but they're definitely going to take a hit, particularly outside the U.S. BTW, I'm remembering from a few years back when the ODF Foundation was still kicking. I did a fair bit of research on the bureaucratic forces in the E.U. that were pushing for the Open Document Exchange Formats. That grew out of a then-ongoing push to get all of the E.U. nations connected via a network that is not dependent on the Internet. It was fairly complete at the time down to the national level and was branching out to the local level and the plan from there was to push connections to business and then to Joe Sixpack and wife. Interop was key, hence ODEF. The E.U. might not be that far away from an ability to sever the digital connections with the U.S. Say a bunch of daisy-chained proxy anonymizers for communications with the U.S. Of course they'd have to block the UK from the network and treat it like it is the U.S. There's a formal signals intelligence service collaboration/integration dating back to WW 2, as I recall, among the U.S., the U.K., Canada, Australia, and New Zealand. Don't remember its name. But it's the same group of nations that were collaborating on Echelon. So the E.U. wouldn't want to let the UK fox inside their new chicken coop. Ah, it's just a fantasy. The U.S. and the E.U. are too interdependent. I have no idea hard it would be for the Zoho folk to come up with desktop/side encryption/decryption. And I don't know whether their servers are located outside the reach of a U.S. court's search warrant. But I think Google is going to have to move in that direction fast if it wants to minimize the damage. Or get way out in front of the hounds chomping at the NSA's ankles and reduce the NSA to compost. OTOH, Google might be a government covert op. for all I know. :-) I'm really enjoying watching the NSA show. Who knows what facet of their Big Brother operation gets revealed next?

    ZOHO is an Indian company with USA marketing offices. No idea where the server farm is located, but they were not on the NSA list. I've known Raju Vegesna for years, mostly from the old Web 2.0 and Office 2.0 Conferences. Raju runs the USA offices in Santa Clara. I'll try to catch up with him on Thursday. How he could miss this once in a lifetime moment to clean out Google, Microsoft and SalesForce.com is something I'd like to find out about. Thanks for the Wuala tip. You sent me that years ago, when i was working on research and design for the SurDocs project. Incredible that all our notes, research, designs and correspondence was left to rot in Google Wave! Too too funny. I recall telling Alex from SurDocs that he had to use a USA host, like Amazon, that could be trusted by USA customers to keep their docs safe and secure. Now look what i've done! I've tossed his entire company information set into the laps of the NSA and their cabal of connected corporatists :)

Civil Rights Coalition files FCC Complaint Against Baltimore Police Department for Illegally Using Stingrays to Disrupt Cellular Communications | Electronic Frontier Foundation - 0 views

surveillance state stingrays test-case litigation

shared by Paul Merrell on 26 Aug 16 - No Cached
  • This week the Center for Media Justice, ColorOfChange.org, and New America’s Open Technology Institute filed a complaint with the Federal Communications Commission alleging the Baltimore police are violating the federal Communications Act by using cell site simulators, also known as Stingrays, that disrupt cellphone calls and interfere with the cellular network—and are doing so in a way that has a disproportionate impact on communities of color. Stingrays operate by mimicking a cell tower and directing all cellphones in a given area to route communications through the Stingray instead of the nearby tower. They are especially pernicious surveillance tools because they collect information on every single phone in a given area—not just the suspect’s phone—this means they allow the police to conduct indiscriminate, dragnet searches. They are also able to locate people inside traditionally-protected private spaces like homes, doctors’ offices, or places of worship. Stingrays can also be configured to capture the content of communications. Because Stingrays operate on the same spectrum as cellular networks but are not actually transmitting communications the way a cell tower would, they interfere with cell phone communications within as much as a 500 meter radius of the device (Baltimore’s devices may be limited to 200 meters). This means that any important phone call placed or text message sent within that radius may not get through. As the complaint notes, “[d]epending on the nature of an emergency, it may be urgently necessary for a caller to reach, for example, a parent or child, doctor, psychiatrist, school, hospital, poison control center, or suicide prevention hotline.” But these and even 911 calls could be blocked.
  • The Baltimore Police Department could be among the most prolific users of cell site simulator technology in the country. A Baltimore detective testified last year that the BPD used Stingrays 4,300 times between 2007 and 2015. Like other law enforcement agencies, Baltimore has used its devices for major and minor crimes—everything from trying to locate a man who had kidnapped two small children to trying to find another man who took his wife’s cellphone during an argument (and later returned it). According to logs obtained by USA Today, the Baltimore PD also used its Stingrays to locate witnesses, to investigate unarmed robberies, and for mysterious “other” purposes. And like other law enforcement agencies, the Baltimore PD has regularly withheld information about Stingrays from defense attorneys, judges, and the public. Moreover, according to the FCC complaint, the Baltimore PD’s use of Stingrays disproportionately impacts African American communities. Coming on the heels of a scathing Department of Justice report finding “BPD engages in a pattern or practice of conduct that violates the Constitution or federal law,” this may not be surprising, but it still should be shocking. The DOJ’s investigation found that BPD not only regularly makes unconstitutional stops and arrests and uses excessive force within African-American communities but also retaliates against people for constitutionally protected expression, and uses enforcement strategies that produce “severe and unjustified disparities in the rates of stops, searches and arrests of African Americans.”
  • Adding Stingrays to this mix means that these same communities are subject to more surveillance that chills speech and are less able to make 911 and other emergency calls than communities where the police aren’t regularly using Stingrays. A map included in the FCC complaint shows exactly how this is impacting Baltimore’s African-American communities. It plots hundreds of addresses where USA Today discovered BPD was using Stingrays over a map of Baltimore’s black population based on 2010 Census data included in the DOJ’s recent report:
  • ...2 more annotations...
  • The Communications Act gives the FCC the authority to regulate radio, television, wire, satellite, and cable communications in all 50 states, the District of Columbia and U.S. territories. This includes being responsible for protecting cellphone networks from disruption and ensuring that emergency calls can be completed under any circumstances. And it requires the FCC to ensure that access to networks is available “to all people of the United States, without discrimination on the basis of race, color, religion, national origin, or sex.” Considering that the spectrum law enforcement is utilizing without permission is public property leased to private companies for the purpose of providing them next generation wireless communications, it goes without saying that the FCC has a duty to act.
  • But we should not assume that the Baltimore Police Department is an outlier—EFF has found that law enforcement has been secretly using stingrays for years and across the country. No community should have to speculate as to whether such a powerful surveillance technology is being used on its residents. Thus, we also ask the FCC to engage in a rule-making proceeding that addresses not only the problem of harmful interference but also the duty of every police department to use Stingrays in a constitutional way, and to publicly disclose—not hide—the facts around acquisition and use of this powerful wireless surveillance technology.  Anyone can support the complaint by tweeting at FCC Commissioners or by signing the petitions hosted by Color of Change or MAG-Net.

Deutsche Telekom to follow Vodafone in revealing surveillance | World news | The Guardian - 0 views

  • Germany's biggest telecoms company is to follow Vodafone in disclosing for the first time the number of surveillance requests it receives from governments around the world.Deutsche Telekom, which owns half of Britain's EE mobile network and operates in 14 countries including the US, Spain and Poland, has already published surveillance data for its home nation – one of the countries that have reacted most angrily to the Edward Snowden revelations. In the wake of Vodafone's disclosures, first published in the Guardian on Friday, it announced that it would extend its disclosures to every other market where it operates and where it is legal.A spokeswoman for Deutsche Telekom, which has 140 million customers worldwide, said: "Deutsche Telekom has initially focused on Germany when it comes to disclosure of government requests. We are currently checking if and to what extent our national companies can disclose information. We intend to publish something similar to Vodafone."
  • Bosses of the world's biggest mobile networks, many of which have headquarters in Europe, are gathering for an industry conference in Shanghai this weekend, and the debate is expected to centre on whether they should join Deutsche and Vodafone in using transparency to push back against the use of their technology for government surveillance.Mobile companies, unlike social networks, cannot operate without a government-issued licence, and have previously been reluctant to discuss the extent of their cooperation with national security and law enforcement agencies.But Vodafone broke cover on Friday by confirming that in around half a dozen of the markets in which it operates, governments in Europe and outside have installed their own secret listening equipment on its network and those of other operators.

    the growing popularity of cloud computing means corporate data centers will increasingly start to look like Internet data centers. Cisco has already recognized that as the "network" continues to become the focal point around which our digital personal and work lives revolve, the opportunity to make money will be immense. That's why Chambers never misses an opportunity to talk about "collaboration." For instance, in the press release announcing the company's latest numbers, he said: "We believe we are entering the next phase of the Internet as growth and productivity will center on collaboration enabled by networked Web 2.0 technologies." But Cisco isn't the only one with this vision - Microsoft (MSFT) and Google (GOOG) are thinking along these lines as well, and are much further ahead in the game.

  • The Internet blackout in Egypt, which we've been covering, touches on an issue we've raised occasionally here: the control of governments (and corporations) over the Internet (and by extension, the cloud). One possible solution, discussed by geeks for years, is the creation of wireless ad-hoc networks like the one in Little Brother to eliminate the need for centralized hardware and network connectivity. It's the sort of technology that's valuable not just for insuring both freedom of speech (not to mention freedom of commerce - Egypt's Internet blackout can't be good for business), but could be valuable in emergencies such as natural disasters as well. Here are a few projects working to create such networks.

  • Hillary Clinton called for the U.S. to promote Internet freedoms earlier this week and introduced a $25 million fund for technology companies that might help with the task. The New America Foundation has already applied for a grant under the program, which includes a $3.5 million proposal, of which $500,000 will be funded by the New America Foundation itself. The mission? To build the technology stack for a distributed, open-source telecommunications system. The project would combine well-known projects — such as the open source voice projects Asterisk and OpenBTS – with new projects for mesh networking known as The Serval Project — which Kevin covered earlier this month — and Commotion, open-source firmware to enable routers to create an open mesh network. Dan Meredith, a technologist at New America, broke it down for me, and said the hope is to deliver communications in areas where Internet access is scarce, but also among populations unable to use communications because of government interference.

There are several digital TV white spaces in the band, and the demands of access points vary over time. "Since in a TV band you don’t get continuous contiguous spectrum—a typical white-space chunk has 6 MHz—you need at least two radios to tune to different bandwidths. Our algorithms decide which radio will choose which bandwidth," says Srinivasan.

    Microsoft last week launched its first serious effort to build IT into its cloud plans by introducing technologies that help connect existing corporate networks and cloud services to make them look like a single infrastructure. The concept began to come together at Microsoft's Professional Developers Conference. The company is attempting to show that it wants to move beyond the first wave of the cloud trend, which is defined by the availability of raw computing power supplied by Microsoft and competitors such as Amazon and Google. Microsoft's goal is to supply tools, middleware, and services so users can run applications that span corporate and cloud networks, especially those built with Microsoft's Azure cloud operating system.
