Who's to blame when an autonomous vehicle crashes? - 3 views

  •  
    Also, here's a link to another article explaining about how google's self-driving car works.
  • ...2 more comments...
  •  
    anyone want to try and describe step by step how this system works?
  •  
    Basically the car works with a Velodyne 64-beam laser mounted on the roof on the car, the laser produces a detailed 3D map of the environment and takes measurements of the area. The car uses the data from the 3D map and the measurements to avoid obstacles and respect traffic laws. Furthermore, the car uses various sensors, two of which are placed on the front and rear bumpers to track obstacles. There is also a camera, that detects traffic lights, GPS, inertial measurement unit, and wheel encoder, that determine the vehicle's location and keep track of its movements. In my opinion, the idea of a self driving car is incredible if it is built correctly, however I believe that the wheel encoder may invade the privacy of some.
  •  
    I'm a bit curious Jorge, how would this invade the privacy of some? This is an amazing technological improvement, it will be interesting to see what happens in the future with this. This is a quite good article on how it works http://news.discovery.com/autos/how-google-self-driving-car-works-111018.html
  •  
    Because the car records it's position using the GPS, if a black hacker is able to get hold of this information the owner of the car could be put at risk.

BBC News - Google admits profiting from illegal Olympic ticket ads - 6 views

  •  
    This article has made clear that the AdWords advertising system is flawed, it is unacceptable for a large company like Google to lead users to believe that a website can be trusted using the 'sponsored links' and continues to make profit. This goes against the 6th point in Google's philosophy "You can make money without doing evil" although they are not doing it consciously. From the article I understood that the system is run using an automated filter to identify websites which break Google's policy and a manual assessment also takes place by a human. Instead of using just one human, a group of humans can assess the adverts to ensure nothing is missed. Furthermore, an update of Google's databases should regularly take place in order to catch illegal websites quicker.

    Here is a list of all Google's philosophy, http://www.google.com/about/corporate/company/tenthings.html
  •  
    Good story this and nice link to Google's philosophy Jorge. This article is a good one for commenting on the relationship between the stakeholder and the IT system. Anyone want to step up and "Describe the relationship of one primary stakeholder to the IT system"?
  •  
    This article raises a huge reliability issue as people are being tricked to buying tickets from fake websites, which are advertised by Google. Due to its increasing reputation over the years, the average internet user will use and think of Google as the most reliable website to navigate, and therefore would trust most of the llinks that would appear when they search for something. The secure and reliable reputation Google has is what makes the fact that these illegal websites being sponsored ads such a large issue. It affects many web users and as they are likely to visit these websites, their personal information such as bank account details and personal details are made public. So security could also be seen as an issue as these people are put at risk as they have given their bank account data to fake websites, who could use the data gain access to bank accounts and steal money.
  •  
    Google's corrupt sponsored links affects nearly every digital citizen, as Google is by far the most popular and used search engine. There is alternatives to Google, but nevertheless Google is the most popular search engine(we're talking 70+% http://www.seoconsultants.com/search-engines/ ) I agree with Jorge's main ideas above. However, I do not think that increasing the number of people checking would make any large difference. It is their filters which needs an update - something I'm sure they're already doing. It does raise some reliability concerns, being the most popular search engine, you'd expect them not to endorse(even unknowingly) corrupt links.
  •  
    The social and ethical issues related to this news story are reliability, privacy and anonimity to an extent. Privacy as the information from the buyers credit card is given to what seems to be an unknown person or company. The multiple stakeholders seen would be the buyer, Google and the advertiser. Although it is via Google that the advertiser gets sell his product, it is important to understand that there are most likely thousands of advertisements added daily to the Google search engine and, referring back to Jorge's point, it would be very likely that humans would fail to see such mistakes as well after repeatedly going through hundreds of adds everyday. The trust and reliance that people have on Google can be misleading and it is evident that to solve such an issue people must be awared of the several scams that they are exposed to every single day in order to prevent this sort of problems.

BBC News - Valve's online game service Steam hit by hackers - 3 views

  • The attackers used login details from the forum hack to access a database that held ID and credit card data
  • The initial investigation showed that the attackers gained access to a Steam database that held "user names, hashed and salted passwords, game purchases, email addresses, billing addresses and encrypted credit card information".
  •  
    This article further increases the already notorious fear of databases containing people's details being accessed by undesired people, who could potentially use this data to cause harm. This raises a serious privacy issue, as, although it has not been confirmed, these hackers have accessed the Steam database which holds up to 35 million people's credit card data and email addresses, posing a threat to a large amount of people. Although it is not known if any harm came of this attack, security measures such as changing password and transferring credit card data to a more secure service (Steam Guard security service) were suggested to Steam users. This is a solution that doesn't undo the harm that has already been made, but is still a positive measure as it can help prevent potential future attacks from hackers on this database.
  •  
    "Valve has officially rolled out its new Steam security system, Steam Guard, which allows users to lock their accounts to a single PC if they so choose. Steam Guard essentially blocks all attempts to access a protected Steam account, then sends verification emails to a registered email address which allow the account owner to monitor account activity and grant access on a single PC at a time. " http://www.bit-tech.net/news/gaming/2011/03/17/valve-launches-steam-guard-security/1 This ensures the 35 million users "the account security they need as they purchase more and more digital goods", especially if they use Steam in public spaces such as cibercafés. http://www.joystiq.com/2011/03/03/valve-introduces-steam-guard-to-fight-acount-phishing-and-hijack/

Device Tracks Blood Flow in the Brain - 2 views

  • A headset ultrasound monitor could make it easier to detect the dangerous aftereffects of brain injuries.
  • The company's monitor consists of a headset that directs an array of ultrasound beams through the head and uses a proprietary algorithm to automatically detect the mid-cerebral artery, one of the major arteries supplying blood to the brain. The device then locks the relevant beam onto the artery and measures its blood flow. A machine attached to the headset gives an index of flow and peak velocity.
  •  
    "A new ultrasound device could make it easier to detect a potentially life-threatening condition". An excellent example of data-logging applied to a practical real-life situation.
  •  
    The invention of this device will drastically improve the monitoring of brain related injuries and in particular the one mentioned in the article - vasospasm. The fact that nearly 50% of soldiers who sustain blast injuries can potentially develop vasospasm is more than enough reason for there to be plenty of funding towards the development of this device. It says in the article that "the company plans to make a more rugged version of its commercial device for the battle field." If the company manages to actually develop this, the amount of soldier deaths in the battle field will decrease as the soldiers will be able to get treatment sooner. Within this development the company could have the data be live streamed to the doctors so that they can analyze the data to see if there is any problem. The data can then be stored so that the patient's development can be recorded. As the device is measuring the blood flow in the brain this could also be used to analyze the soldiers brain whilst on the field. This could contribute to developments in other studies of the brain like post-traumatic stress.

BBC News - TripAdvisor rebuked over 'trust' claims on review site - 2 views

  • TripAdvisor rebuked over 'trust' claims on review site

    TripAdvisor screenshot The travel site's UK homepage no longer makes the claims that provoked the complaints

    Related Stories

    TripAdvisor has been ordered to rewrite some of its marketing claims by the UK's Advertising Standards Authority.

    The ruling follows complaints by hotels that the site had said that its holiday reviews could be "trusted".

    The ASA said it was concerned that consumers might be fooled by fraudulent posts since the entries could be made "without any form of verification".

    TripAdvisor described the ruling as a "highly technical view" of "copy that was used in a limited capacity".

    However, the watchdog said that the ruling served as a warning to all UK-focused sites with user-generated material.

    Fraud systems

    The ASA said that the US-based firm's site originally carried statements saying that it contained "reviews that you can trust" and that it had "more than 50 million honest travel reviews".

    It said that two hotels and the online reputation firm Kwikchex, which represented others, had complained that the claims were misleading since they could not be substantiated.

    The advertising body said it acknowledged that reviewers were asked to sign a declaration that their reviews were real and that they had no incentive or competitive interest with the places commented on.

    Don't major on trustworthiness if fake reviews can appear”

  • "This should be regarded as a benchmark ruling which applies to all web sites which make claims about the reliability of their user-created content," the ASA's spokesman Matthew Wilson told the BBC.

  • When asked about this the ASA said that its remit only extended to claims targeted at a UK audience, so it would not be pursuing changes at the .com site.

    the social and ethical issue here is reliability. No one can be completely confident that what they see online is true whether it is with traveling companies or something mr brooke showed us in class: http://www.familywatchdog.us/search.asp in this website for example, we can not be sure that the people registered really are sex offenders.

BBC News - Hackers outwit online banking identity security systems - 3 views

    Criminal hackers have found a way round the latest generation of online banking security devices given out by banks, the BBC has learned.
  • ...1 more comment...
  •  
    The main social and ethical issues here are mainly security and reliability, it is interesting how the hackers use malware software to obtain the users information. What is more concerning is the fact that it is difficult for the account owner to actually realise any suspicious activity due to the fact the hackers are able to alter the banks database details in order to display a normal online statement. In most cases a up to date anti-virus is recommended however, according to the bbc click investigation most of the security softwares did not pick up the malware software.
  •  
    I agree with Jorge. There are various ways in which hackers can obtain personal information by the internet. One way by which hackers can do this is by phishing. In this article, account holders are being tricked by the offer of training in a new "upgraded security system", meaning that account holders click on the link and their money is moved out of their account without them even noticing! This is a big problem, and as this article says "Online banking fraud losses totalled £16.9 million in the first six months of 2011, according to Financial Fraud Action UK" therefore in only 6 months, millions of pounds were gone! Phishing is increasing more and more, some day we can't even click a link because we're scared it could be something similar!

BBC News - Trendnet security cam flaw exposes video feeds on net - 8 views

  • "We first became aware of this on 12 January," said Zak Wood, Trendnet's director of global marketing.
  •  
    SO scary!!!!!! After reading this shocking article I'll probably start covering my security cameras while I'm at home! A main social and ethical issue is SURELY privacy. I think that many people aren't aware that security is coming to bits by the second, privacy isn't what it was some years ago. And, in my opinion, it's the technology's fault. Even though computers, internet, phones etc have become useful, society's becoming too much dependent to technology and this is an issue as technology will continue to increase even more, meaning that society's privacy will continue to decrease even more. Can't we even have privacy at home?
  •  
    To some extent I agree with you Ines. But technology isn't all bad. Yes, we are losing privacy at a rapid pace. But these cameras provided us with security. Well, they would have if it wasn't for the breach in Trendnet's security they would have provided people with security. Our world has become much dependent on social networking etc. We do not have as much privacy as one would like, but this is not solely the technology fault in my opinion. It is as much human nature, the drive to have 15 minutes of fame. Just my two cents anyway : )
  •  
    The IT system in focus is the Trendnet home security camera. Here is how real-time, live video broadcasting works. This information originally referred to IP based cameras, which essentially work the same way. Image: http://www.ipcctv.com/images/learnMore/Single-Camera.gif The camera is installed and ran "The camera turns video & audio into binary data The camera connects to your the and transmits this data onto the network This data can then be viewed on a PC; on the local network, or over the internet." The remote viewer inputs the Internet addresses which link to the video streams and is able to see footage. source: http://www.ipcctv.com/article.php?xArt=13

Over 3 years later, "deleted" Facebook photos are still online - 2 views

  • "did not always delete images from content delivery networks in a reasonable period of time even though they were immediately removed from the site,
  • In the meantime, photos that users thought they "deleted" from the social network months or even years ago remain accessible via direct link.
  • "working with our content delivery network (CDN) partner to significantly reduce the amount of time that backup copies persist."
  • ...1 more annotation...
  • but said the company is working on a new system that will delete the photos in a mere month and a half
  •  
    I find, in this scenario, Facebook's behaviour immoral. They have known of this problem for three years, and they have yet to produce any progress. Facebook does not seem to respect one's stance on these things. If you wish the picture deleted, then it should be deleted.
  • ...2 more comments...
  •  
    I agree with Morten, if Facebook has known this problem for the past three years they should have done something about it not wait for someone to find out and then apologise and attempt to fix the problem later. However, i'm not quite sure on how this works because I have had friends send me links to pictures that were deleted minutes before and a content error appears and i'm not able to access the picture/link.
  •  
    Jorge I think the difference is that if you have a direct link ie the url of the image then you can still see it. A link from someone's wall will be broken and the image will appear to have gone.
  •  
    The apparent deletion of photos takes place by the elimination "all of the metadata for the photo as well as any and all tagging and linking information. For all practical purposes, the photo no longer exists. However, technically, the bits that make up the photo persist somewhere. It's possible that someone who previously had access to a photo and saved the direct URL from the CDN (...) could still access the photo." http://webapps.stackexchange.com/questions/2493/how-long-does-facebook-keep-data-of-a-deleted-account In the article, "Wolens claims that Facebook is on the verge of fixing up its content systems so that "deleted" photos are really, truly deleted from the CDN within 45 days." However, the reliability of this claim is compromised by Facebook's Terms of Service, which every user must comply prior to creating an account. Summing up, it grants Facebook the right to do whatever they like with old content. They can even sublicense it: "You hereby grant Facebook an irrevocable, perpetual, non-exclusive, transferable, fully paid, worldwide license (with the right to sublicense) to (a) use, copy, publish, stream, store, retain, publicly perform or display, transmit, scan, reformat, modify, edit, frame, translate, excerpt, adapt, create derivative works and DISTRIBUTE (through multiple tiers), any User Content." http://consumerist.com/2009/02/facebooks-new-terms-of-service-we-can-do-anything-we-want-with-your-content-forever.html Note the contradictions with the principles of the Data Protection Act 1998: "If you collect data about people for one reason, you can not use it for another; You can not give people's data to other people or
  •  
    ...organizations unless they agree;" http://simple.wikipedia.org/wiki/Data_Protection_Act I get the impression that through blurring the ownership of intellectual property and personal records, social networks have some ulterior motives. The following passage in the article suggests the photos could, in fact, be instantly deleted from the CDN databases: "(Amusingly, after publishing the 2010 followup, Facebook appeared to delete my photos from its CDN that I had linked in the piece. (...) Other "deleted" photos that I had saved links to-ones that weren't from my account and were deleted even earlier than mine-remained online.)" Zuckerberg counterargues: "trust us, we're not doing this to profit from you, it's so we are legally protected as we enable you to share content with other users and services." http://consumerist.com/2009/02/facebooks-new-terms-of-service-we-can-do-anything-we-want-with-your-content-forever.html In the end, it is in the hands of the user to control what is shared and given up ownership of.
