OWL 2 Web Ontology Language:New Features and Rationale - 0 views

  • Abstract OWL 2 extends the W3C OWL Web Ontology Language with a small but useful set of features that have been requested by users, for which effective reasoning algorithms are now available, and that OWL tool developers are willing to support. The new features include extra syntactic sugar, additional property and qualified cardinality constructors, extended datatype support, simple metamodeling, and extended annotations. This document is a simple introduction to the new features of the OWL 2 Web Ontology Language, including an explanation of its differences with respect to OWL 1. It also presents the requirements that have motivated the design of the main new features, and their rationale from a theoretical and implementation perspective.

The Self-Describing Web - 0 views

  • Abstract The Web is designed to support flexible exploration of information by human users and by automated agents. For such exploration to be productive, information published by many different sources and for a variety of purposes must be comprehensible to a wide range of Web client software, and to users of that software. HTTP and other Web technologies can be used to deploy resource representations that are in an important sense self-describing: information about the encodings used for each representation is provided explicitly within the representation. Starting with a URI, there is a standard algorithm that a user agent can apply to retrieve and interpret such representations. Furthermore, representations can be grounded in the Web, by ensuring that specifications required to interpret them are determined unambiguously based on the URI, and that explicit references connect the pertinent specifications to each other. Web-grounding reduces ambiguity as to what has been published in the Web, and by whom. When such self-describing, Web-grounded resources are linked together, the Web as a whole can support reliable, ad hoc discovery of information. This finding describes how document formats, markup conventions, attribute values, and other data formats can be designed to facilitate the deployment of self-describing, Web-grounded Web content.

European Lawmakers Demand Answers on Phone Key Theft - The Intercept - 0 views

  • European officials are demanding answers and investigations into a joint U.S. and U.K. hack of the world’s largest manufacturer of mobile SIM cards, following a report published by The Intercept Thursday. The report, based on leaked documents provided by NSA whistleblower Edward Snowden, revealed the U.S. spy agency and its British counterpart Government Communications Headquarters, GCHQ, hacked the Franco-Dutch digital security giant Gemalto in a sophisticated heist of encrypted cell-phone keys. The European Parliament’s chief negotiator on the European Union’s data protection law, Jan Philipp Albrecht, said the hack was “obviously based on some illegal activities.” “Member states like the U.K. are frankly not respecting the [law of the] Netherlands and partner states,” Albrecht told the Wall Street Journal. Sophie in ’t Veld, an EU parliamentarian with D66, the Netherlands’ largest opposition party, added, “Year after year we have heard about cowboy practices of secret services, but governments did nothing and kept quiet […] In fact, those very same governments push for ever-more surveillance capabilities, while it remains unclear how effective these practices are.”
  • “If the average IT whizzkid breaks into a company system, he’ll end up behind bars,” In ’t Veld added in a tweet Friday. The EU itself is barred from undertaking such investigations, leaving individual countries responsible for looking into cases that impact their national security matters. “We even get letters from the U.K. government saying we shouldn’t deal with these issues because it’s their own issue of national security,” Albrecht said. Still, lawmakers in the Netherlands are seeking investigations. Gerard Schouw, a Dutch member of parliament, also with the D66 party, has called on Ronald Plasterk, the Dutch minister of the interior, to answer questions before parliament. On Tuesday, the Dutch parliament will debate Schouw’s request. Additionally, European legal experts tell The Intercept, public prosecutors in EU member states that are both party to the Cybercrime Convention, which prohibits computer hacking, and home to Gemalto subsidiaries could pursue investigations into the breach of the company’s systems.
  • According to secret documents from 2010 and 2011, a joint NSA-GCHQ unit penetrated Gemalto’s internal networks and infiltrated the private communications of its employees in order to steal encryption keys, embedded on tiny SIM cards, which are used to protect the privacy of cellphone communications across the world. Gemalto produces some 2 billion SIM cards a year. The company’s clients include AT&T, T-Mobile, Verizon, Sprint and some 450 wireless network providers. “[We] believe we have their entire network,” GCHQ boasted in a leaked slide, referring to the Gemalto heist.

  • While Gemalto was indeed another casualty in Western governments’ sweeping effort to gather as much global intelligence advantage as possible, the leaked documents make clear that the company was specifically targeted. According to the materials published Thursday, GCHQ used a specific codename — DAPINO GAMMA — to refer to the operations against Gemalto. The spies also actively penetrated the email and social media accounts of Gemalto employees across the world in an effort to steal the company’s encryption keys. Evidence of the Gemalto breach rattled the digital security community. “Almost everyone in the world carries cell phones and this is an unprecedented mass attack on the privacy of citizens worldwide,” said Greg Nojeim, senior counsel at the Center for Democracy & Technology, a non-profit that advocates for digital privacy and free online expression. “While there is certainly value in targeted surveillance of cell phone communications, this coordinated subversion of the trusted technical security infrastructure of cell phones means the US and British governments now have easy access to our mobile communications.”
  • For Gemalto, evidence that their vaunted security systems and the privacy of customers had been compromised by the world’s top spy agencies made an immediate financial impact. The company’s shares took a dive on the Paris bourse Friday, falling $500 million. In the U.S., Gemalto’s shares fell as much 10 percent Friday morning. They had recovered somewhat — down 4 percent — by the close of trading on the Euronext stock exchange. Analysts at Dutch financial services company Rabobank speculated in a research note that Gemalto could be forced to recall “a large number” of SIM cards. The French daily L’Express noted today that Gemalto board member Alex Mandl was a founding trustee of the CIA-funded venture capital firm In-Q-Tel. Mandl resigned from In-Q-Tel’s board in 2002, when he was appointed CEO of Gemplus, which later merged with another company to become Gemalto. But the CIA connection still dogged Mandl, with the French press regularly insinuating that American spies could infiltrate the company. In 2003, a group of French lawmakers tried unsuccessfully to create a commission to investigate Gemplus’s ties to the CIA and its implications for the security of SIM cards. Mandl, an Austrian-American businessman who was once a top executive at AT&T, has denied that he had any relationship with the CIA beyond In-Q-Tel. In 2002, he said he did not even have a security clearance.
  • AT&T, T-Mobile and Verizon could not be reached for comment Friday. Sprint declined to comment. Vodafone, the world’s second largest telecom provider by subscribers and a customer of Gemalto, said in a statement, “[W]e have no further details of these allegations which are industrywide in nature and are not focused on any one mobile operator. We will support industry bodies and Gemalto in their investigations.” Deutsche Telekom AG, a German company, said it has changed encryption algorithms in its Gemalto SIM cards. “We currently have no knowledge that this additional protection mechanism has been compromised,” the company said in a statement. “However, we cannot rule out this completely.”
  • Update: Asked about the SIM card heist, White House press secretary Josh Earnest said he did not expect the news would hurt relations with the tech industry: “It’s hard for me to imagine that there are a lot of technology executives that are out there that are in a position of saying that they hope that people who wish harm to this country will be able to use their technology to do so. So, I do think in fact that there are opportunities for the private sector and the federal government to coordinate and to cooperate on these efforts, both to keep the country safe, but also to protect our civil liberties.”
  •  
    Watch for massive class action product defect litigation to be filed against the phone companies.and mobile device manufacturers.  In most U.S. jurisdictions, proof that the vendors/manufacturers  knew of the product defect is not required, only proof of the defect. Also, this is a golden opportunity for anyone who wants to get out of a pricey cellphone contract, since providing a compromised cellphone is a material breach of warranty, whether explicit or implied..

NZ Prime Minister John Key Retracts Vow to Resign if Mass Surveillance Is Shown - 0 views

  • In August 2013, as evidence emerged of the active participation by New Zealand in the “Five Eyes” mass surveillance program exposed by Edward Snowden, the country’s conservative Prime Minister, John Key, vehemently denied that his government engages in such spying. He went beyond mere denials, expressly vowing to resign if it were ever proven that his government engages in mass surveillance of New Zealanders. He issued that denial, and the accompanying resignation vow, in order to reassure the country over fears provoked by a new bill he advocated to increase the surveillance powers of that country’s spying agency, Government Communications Security Bureau (GCSB) — a bill that passed by one vote thanks to the Prime Minister’s guarantees that the new law would not permit mass surveillance.
  • Since then, a mountain of evidence has been presented that indisputably proves that New Zealand does exactly that which Prime Minister Key vehemently denied — exactly that which he said he would resign if it were proven was done. Last September, we reported on a secret program of mass surveillance at least partially implemented by the Key government that was designed to exploit the very law that Key was publicly insisting did not permit mass surveillance. At the time, Snowden, citing that report as well as his own personal knowledge of GCSB’s participation in the mass surveillance tool XKEYSCORE, wrote in an article for The Intercept: Let me be clear: any statement that mass surveillance is not performed in New Zealand, or that the internet communications are not comprehensively intercepted and monitored, or that this is not intentionally and actively abetted by the GCSB, is categorically false. . . . The prime minister’s claim to the public, that “there is no and there never has been any mass surveillance” is false. The GCSB, whose operations he is responsible for, is directly involved in the untargeted, bulk interception and algorithmic analysis of private communications sent via internet, satellite, radio, and phone networks.
  • A series of new reports last week by New Zealand journalist Nicky Hager, working with my Intercept colleague Ryan Gallagher, has added substantial proof demonstrating GCSB’s widespread use of mass surveillance. An article last week in The New Zealand Herald demonstrated that “New Zealand’s electronic surveillance agency, the GCSB, has dramatically expanded its spying operations during the years of John Key’s National Government and is automatically funnelling vast amounts of intelligence to the US National Security Agency.” Specifically, its “intelligence base at Waihopai has moved to ‘full-take collection,’ indiscriminately intercepting Asia-Pacific communications and providing them en masse to the NSA through the controversial NSA intelligence system XKeyscore, which is used to monitor emails and internet browsing habits.” Moreover, the documents “reveal that most of the targets are not security threats to New Zealand, as has been suggested by the Government,” but “instead, the GCSB directs its spying against a surprising array of New Zealand’s friends, trading partners and close Pacific neighbours.” A second report late last week published jointly by Hager and The Intercept detailed the role played by GCSB’s Waihopai base in aiding NSA’s mass surveillance activities in the Pacific (as Hager was working with The Intercept on these stories, his house was raided by New Zealand police for 10 hours, ostensibly to find Hager’s source for a story he published that was politically damaging to Key).

  • That the New Zealand government engages in precisely the mass surveillance activities Key vehemently denied is now barely in dispute. Indeed, a former director of GCSB under Key, Sir Bruce Ferguson, while denying any abuse of New Zealander’s communications, now admits that the agency engages in mass surveillance.
  • Meanwhile, Russel Norman, the head of the country’s Green Party, said in response to these stories that New Zealand is “committing crimes” against its neighbors in the Pacific by subjecting them to mass surveillance, and insists that the Key government broke the law because that dragnet necessarily includes the communications of New Zealand citizens when they travel in the region.
  • So now that it’s proven that New Zealand does exactly that which Prime Minister Key vowed would cause him to resign if it were proven, is he preparing his resignation speech? No: that’s something a political official with a minimal amount of integrity would do. Instead — even as he now refuses to say what he has repeatedly said before: that GCSB does not engage in mass surveillance — he’s simply retracting his pledge as though it were a minor irritant, something to be casually tossed aside:
  • When asked late last week whether New Zealanders have a right to know what their government is doing in the realm of digital surveillance, the Prime Minister said: “as a general rule, no.” And he expressly refuses to say whether New Zealand is doing that which he swore repeatedly it was not doing, as this excellent interview from Radio New Zealand sets forth: Interviewer: “Nicky Hager’s revelations late last week . . . have stoked fears that New Zealanders’ communications are being indiscriminately caught in that net. . . . The Prime Minister, John Key, has in the past promised to resign if it were found to be mass surveillance of New Zealanders . . . Earlier, Mr. Key was unable to give me an assurance that mass collection of communications from New Zealanders in the Pacific was not taking place.” PM Key: “No, I can’t. I read the transcript [of former GCSB Director Bruce Ferguson’s interview] – I didn’t hear the interview – but I read the transcript, and you know, look, there’s a variety of interpretations – I’m not going to critique–”
  • Interviewer: “OK, I’m not asking for a critique. Let’s listen to what Bruce Ferguson did tell us on Friday:” Ferguson: “The whole method of surveillance these days, is sort of a mass collection situation – individualized: that is mission impossible.” Interviewer: “And he repeated that several times, using the analogy of a net which scoops up all the information. . . . I’m not asking for a critique with respect to him. Can you confirm whether he is right or wrong?” Key: “Uh, well I’m not going to go and critique the guy. And I’m not going to give a view of whether he’s right or wrong” . . . . Interviewer: “So is there mass collection of personal data of New Zealand citizens in the Pacific or not?” Key: “I’m just not going to comment on where we have particular targets, except to say that where we go and collect particular information, there is always a good reason for that.”
  • From “I will resign if it’s shown we engage in mass surveillance of New Zealanders” to “I won’t say if we’re doing it” and “I won’t quit either way despite my prior pledges.” Listen to the whole interview: both to see the type of adversarial questioning to which U.S. political leaders are so rarely subjected, but also to see just how obfuscating Key’s answers are. The history of reporting from the Snowden archive has been one of serial dishonesty from numerous governments: such as the way European officials at first pretended to be outraged victims of NSA only for it to be revealed that, in many ways, they are active collaborators in the very system they were denouncing. But, outside of the U.S. and U.K. itself, the Key government has easily been the most dishonest over the last 20 months: one of the most shocking stories I’ve seen during this time was how the Prime Minister simultaneously plotted in secret to exploit the 2013 proposed law to implement mass surveillance at exactly the same time that he persuaded the public to support it by explicitly insisting that it would not allow mass surveillance. But overtly reneging on a public pledge to resign is a new level of political scandal. Key was just re-elected for his third term, and like any political official who stays in power too long, he has the despot’s mentality that he’s beyond all ethical norms and constraints. But by the admission of his own former GCSB chief, he has now been caught red-handed doing exactly that which he swore to the public would cause him to resign if it were proven. If nothing else, the New Zealand media ought to treat that public deception from its highest political official with the level of seriousness it deserves.

  • Boxcryptor is an easy-to-use encryption software optimized for the cloud. It allows the secure use of cloud storage services without sacrificing comfort. Boxcryptor supports all major cloud storage providers (such as Dropbox, Google Drive, Microsoft OneDrive, SugarSync) and supports all the clouds that use the WebDAV standard (such as Cubby, Strato HiDrive, and ownCloud). With Boxcryptor your files go protected to your cloud provider and you can enjoy peace of mind knowing that your information cannot fall into the wrong hands. Here is how it works: Boxcryptor creates a virtual drive on your computer that allows you to encrypt your files locally before uploading them to your cloud or clouds of choice. It encrypts individual files - and does not create containers. Any file dropped into an encrypted folder within the Boxcryptor drive will get automatically encrypted before it is synced to the cloud. To protect your files, Boxcryptor uses the AES-256 and RSA encryption algorithms.
  •  
    Free for personal use. I haven't tried this yet, but the need for it has been near the top of my head since I first tried Dropbox and then realized how insecure it was. I tried a lot of sync services, but am now using Wuala, which features end-to-end encryption baked into the client software. But I also use MEGAsync for remote backup so I'[ll probably be trying this out with that service. I hope there's a way to sync the two programs.

Deep Fakes: A Looming Crisis for National Security, Democracy and Privacy? - Lawfare - 1 views

  • “We are truly fucked.” That was Motherboard’s spot-on reaction to deep fake sex videos (realistic-looking videos that swap a person’s face into sex scenes actually involving other people). And that sleazy application is just the tip of the iceberg. As Julian Sanchez tweeted, “The prospect of any Internet rando being able to swap anyone’s face into porn is incredibly creepy. But my first thought is that we have not even scratched the surface of how bad ‘fake news’ is going to get.” Indeed. Recent events amply demonstrate that false claims—even preposterous ones—can be peddled with unprecedented success today thanks to a combination of social media ubiquity and virality, cognitive biases, filter bubbles, and group polarization. The resulting harms are significant for individuals, businesses, and democracy. Belated recognition of the problem has spurred a variety of efforts to address this most recent illustration of truth decay, and at first blush there seems to be reason for optimism. Alas, the problem may soon take a significant turn for the worse thanks to deep fakes. Get used to hearing that phrase. It refers to digital manipulation of sound, images, or video to impersonate someone or make it appear that a person did something—and to do so in a manner that is increasingly realistic, to the point that the unaided observer cannot detect the fake. Think of it as a destructive variation of the Turing test: imitation designed to mislead and deceive rather than to emulate and iterate.
  • Fueled by artificial intelligence, digital impersonation is on the rise. Machine-learning algorithms (often neural networks) combined with facial-mapping software enable the cheap and easy fabrication of content that hijacks one’s identity—voice, face, body. Deep fake technology inserts individuals’ faces into videos without their permission. The result is “believable videos of people doing and saying things they never did.” Not surprisingly, this concept has been quickly leveraged to sleazy ends. The latest craze is fake sex videos featuring celebrities like Gal Gadot and Emma Watson. Although the sex scenes look realistic, they are not consensual cyber porn. Conscripting individuals (more often women) into fake porn undermines their agency, reduces them to sexual objects, engenders feeling of embarrassment and shame, and inflicts reputational harm that can devastate careers (especially for everyday people). Regrettably, cyber stalkers are sure to use fake sex videos to torment victims. What comes next? We can expect to see deep fakes used in other abusive, individually-targeted ways, such as undermining a rival’s relationship with fake evidence of an affair or an enemy’s career with fake evidence of a racist comment.

YouTube To Censor "Controversial" Content, ADL On Board As Flagger - 0 views

  • Chief among the groups seeking to clamp down on independent media has been Google, the massive technology company with deep connections to the U.S. intelligence community, as well as to U.S. government and business elites.
  • Since 2015, Google has worked to become the Internet’s “Ministry of Truth,” first through its creation of the First Draft Coalition and more recently via major changes made to its search engine that curtail public access to new sites independent of the corporate media.
  • Google has now stepped up its war on free speech and the freedom of the press through its popular subsidiary, YouTube. On Tuesday, YouTube announced online that it is set to begin censoring content deemed “controversial,” even if that content does not break any laws or violate YouTube’s user agreement. Misleadingly dubbed as an effort “to fight terror content online,” the new program will flag content for review through a mix of machine algorithms and “human review,” guided by standards set up by “expert NGOs and institutions” that are part of YouTube’s “Trusted Flagger” program. YouTube stated that such organizations “bring expert knowledge of complex issues like hate speech, radicalization, and terrorism.” One of the leading institutions directing the course of the Trusted Flagger program is the Anti-Defamation League (ADL). The ADL was initially founded to “stop the defamation of the Jewish people and to secure justice and fair treatment to all” but has gained a reputation over the years for labeling any critic of Israel’s government as an “anti-Semite.” For instance, characterizing Israeli policies towards the Palestinians as “racist” or “apartheid-like” is considered “hate speech” by the ADL, as is accusing Israel of war crimes or attempted ethnic cleansing. The ADL has even described explicitly Jewish organizations who are critical of Israel’s government as being “anti-Semitic.”

Google Censors Block Access to CounterPunch and Other Progressive Sites - 0 views

  • Now Google, at the behest of its friends in Washington, is actively censoring – essentially blocking access to – any websites which seek to warn American workers of the ongoing effort to further attack their incomes, social services, and life conditions by the U.S. central government, and which seek to warn against the impending warfare between U.S.-led Nato and other forces against countries like Iran, Russia, and China, which have in no way threatened the U.S. state or its people
  • Under its new so-called anti-fake-news program, Google algorithms have in the past few months moved socialist, anti-war, and progressive websites from previously prominent positions in Google searches to positions up to 50 search result pages from the first page, essentially removing them from the search results any searcher will see.    CounterPunch, World Socialist Website, Democracy Now, American Civil liberties Union, Wikileaks are just a few of the websites which have experienced severe reductions in their returns from Google searches.  World Socialist Website, to cite just one example, has experienced a 67% drop in its returns from Google since the new policy was announced. This conversion of Google into a Censorship engine is not a trivial development.   Google searches are currently a primary means by which workers and other members of the public seek information about their lives and their world.  Every effort must be made to combat this serious infringement on the basic rights of freedom of speech and freedom of press.

Google will 'de-rank' RT articles to make them harder to find - Eric Schmidt - RT World... - 0 views

  • Eric Schmidt, the Executive Chairman of Google’s parent company Alphabet, says the company will “engineer” specific algorithms for RT and Sputnik to make their articles less prominent on the search engine’s news delivery services. “We are working on detecting and de-ranking those kinds of sites – it’s basically RT and Sputnik,” Schmidt said during a Q & A session at the Halifax International Security Forum in Canada on Saturday, when asked about whether Google facilitates “Russian propaganda.”
  • “We are well of aware of it, and we are trying to engineer the systems to prevent that [the content being delivered to wide audiences]. But we don’t want to ban the sites – that’s not how we operate.”The discussion focused on the company’s popular Google News service, which clusters the news by stories, then ranks the various media outlets depending on their reach, article length and veracity, and Google Alerts, which proactively informs subscribers of new publications.
  • The Alphabet chief, who has been referred to by Hillary Clinton as a “longtime friend,” added that the experience of “the last year” showed that audiences could not be trusted to distinguish fake and real news for themselves.“We started with the default American view that ‘bad’ speech would be replaced with ‘good’ speech, but the problem found in the last year is that this may not be true in certain situations, especially when you have a well-funded opponent who is trying to actively spread this information,” he told the audience.
