Who Owns Your Data? - 0 views

datacollection dataownership datamining ownership data

shared by Roland Gesthuizen on 31 May 12 - No Cached
  • But as we use the Internet for “free,” we have to remember that if we’re not paying for something, we’re not the customer. We are in fact the product being sold — or, more specifically, our data is. So here’s a tricky question: Who owns all that data?
  • The digital divide isn’t about who owns data — it’s about who can put that data to work.

twitter data demographic bigdata API geocoding

shared by Roland Gesthuizen on 22 Jul 13 - No Cached
  • All that’s not to say that Twitter’s not incredibly useful as a data source
  • Just be aware of its limits and be careful about assuming what it produces represents any larger reality
  • different versions of Twitter data can return different — sometimes even mutually contradictory — results
  • Roland Gesthuizen on 22 Jul 13
     
    "At Source, Jacob Harris notes that, as appealing as the Twitter API may be as a source of what-people-are-thinking data, it's hardly perfect. Twitter's demographics aren't representative of either Internet users as a whole or the broader population, and geocoding data is sparse and inconsistent. "

    Semantic Web technologies have immense potential to transform the Internet into a distributed reasoning machine that will not only execute extremely precise searches, but will also have the ability to analyze the data it finds to create new knowledge. This paper examines the state of Semantic Web (also known as Linked Data) tools and infrastructure to determine whether semantic technologies are sufficiently mature for non-expert use, and to identify some of the obstacles to global Linked Data implementation.

  • Enterprises are using data analysis not just to improve their everyday business processes, but also to build predictive models of consumer behaviour.
  • Trained loyalty scientists build systems that trawl through a company's customer behaviour data to predict certain events, such as what might prompt them to leave
  • Companies approaching customers need to be ''utterly transparent'' about how they know what they know about a customer.
  • Roland Gesthuizen on 23 May 12
     
    "Big data is the new business black. It's a catch-all phrase for the billions of transactions and other bits of information about their customers, suppliers and operations logged by businesses and governments the world over every day. Yesterday's storage problem has become today's strategic asset. Turns out there's gold in them thar files."

  • Traitorware is sometimes included in products with less obviously malicious intent.
  • Don’t let these good intentions fool you—software that hides itself from you while it gives your personal data away to a third party is dangerous and dishonest.
  • traitorware: devices that act behind your back to betray your privacy.

    "Traitorware is not some science-fiction vision of the future. It is the present. .. We believe that your software and devices should not be a tool for gathering your personal data without your explicit consent. "

Victoria privacy offshore CloudComputing law legal

shared by Roland Gesthuizen on 05 May 11 - No Cached
  • cloud computing was being used “increasingly” by Victorian agencies, in order to reduce capital and operational costs.
  • Given that many cloud computing service providers are in jurisdictions which do not have similar privacy or data protection laws, if a security breach occurs, an individual in Victoria will be powerless to take action against the cloud service provider and will only be able to complain to the Victorian government organisation
  • large organisations need to look in a more granular fashion at what sort of data they are interested in storing in the cloud — arguing that some data could be harmlessly stored offshore — compared with sensitive data
  • Roland Gesthuizen on 05 May 11
     
    "Victoria's privacy commissioner has issued a stark warning to government agencies about the use of cloud computing, warning that it may be "impossible" to protect personal information held about Australians when it was located offshore - or even just outside Victoria."

  • Google uses its own custom, stripped down version of Linux. It uses only a minimum set of packages.
  • The facilities are hypersecure - vehicles can't enter without authorization, and iris scanners are used at some locations.

    "Google is famously secretive about its data centers, so a new video on its enterprise blog that gives a glimpse into the inner workings of its facilities is a rare treat. The video emphasizes security and environmental best practices."

    Web giants like Google and Amazon are notoriously secretive about what goes on inside the worldwide network of data centers that serve up their sweeping collection of web services. They call it a security measure, but clearly, they also see these facilities as some sort of competitive advantage their online rivals mustn't lay eyes on.

  • other university students started looking at a public transport's ticketing system because they were fans of public transport and interested in how the data was encrypted. They were also interested in what protections were in place against malicious users creating fake tickets
  • they were already aware of the potential flaws, but it was a large and expensive operation to change the tickets
  • cryptography should be impossible to crack, even if a potential attacker or reverse engineer knows every detail about how it is implemented. This system on the other hand is relying completely on users not knowing how it is implemented, which may have been fine when it was introduced in the early '90s because much fewer people had access to the technology required to read the tickets, or computers fast enough to analyse the data
  • Roland Gesthuizen on 01 May 13
     
    "A team of university students in Sydney have cracked the secret algorithm used on Sydney's public transport tickets for buses, trains and ferries, which they say could allow them to print their own tickets. "

    "Let's get the harsh facts out there first - IT's in trouble, deep trouble. It has become way too reactionary. By IT I mean 'traditional' IT, the time honored 'old school' way of doing things. The pace of tech adoption is accelerating. By rights this should be a terrific opportunity for technologists and IT teams. In reality, old school IT has been shocked and awed by the consumerization of IT. "

    "Clearly, there's a need for multiple backups.  The questions are, how? and how many? .. For most of us, it's all in one place, so we need a single strategy -- one, two, or more backups. But if you have original data on separate Macs and/or external drives, you may want more backups of one than others. How?  There are several ways to have multiple backups, detailed below:"
