Visible to anyone in the world

I read the article given on the links.

In the given case, Netflix runs a contest and lure people for prize money. It is a longitudinal contest means they received lots of data. In this way, they collected lots of methods and techniques.

Amazon uses various tactics such as item-to-item collaborative filtering which is based on our browsing history. They also use customer reviews and recommendations to attract customers. Amazon employee plays an important role to catch our purchasing and browsing behaviour. They also create occasional hype like BLACK FRIDAY SALE.

Privacy Crisis and Big Data

I searched for “big data” for Facebook. I read that Facebook is using our data for the business purpose. Our information is being shared with others without letting us know.  In fact, data to target US, voters were sold to Cambridge Analytica is accused of using that data to target US voters during 2016 elections. Recently Europen Union has passed data privacy bill to ensure the right to privacy.

I then searched for the Google big data. It says that big data means a well-structured data, which is produced in the form of text, video, images and audio. Google has developed open source tools that are used for big data purposes. Example, Google use semantics for the purpose of Google search engine.  Cloud computing is one of the best data storage and analytic place.
