Big Data: How it is used, Pros and Cons.

By this time we are all aware that by accessing digital services we do forfeit information about us in order to be granted access. These kinds of services cut across the spectrum, from social media to supermarket shopping. It is improbable to skip financial services that are increasingly penetrating the rural with little difficulty. Big data has revolutionized the way institutions of service get informed about the people they are meant to serve. It is futile to keep serving people that you do not know about their needs or priorities or even habits. It pays to meet the need of the customer at the right time. Also, being connected with those one care about through a social platform is commendable. Equally, it is a plus purchasing a product online and find it home without going to the store kilometers away from both your workplace and residence.

By the year 2009, it was estimated that a company of 1000 customers already had 200 terabytes of data of their customer lives(Monnappa, 2020). Netflix’s prize contest (USD 1m) for big data programmers was intended to predict whether someone will enjoy a movie based on how much they liked or disliked other movies (Netflix, 2009). The movie company predicts consumer behavior in order to maximize profits. (good or bad, it works!). Amazon, on the other hand, uses a recommendation system, These recommendations are based on what the user bought in the past, items in the virtual shopping cart, rated, liked, viewed or purchased(Mangalindan, 2012). Take a pick of a few of your favorite sites (ones you interact with often), let’s say, Facebook, Twitter, online store among others, how much data is collected and stored about your daily activities? It is easier to predict your behavioral and emotional patterns to the benefit of the store marketing team or social media advertising agency.

In spite of all the good things, we enjoy utilizing the digital platforms, everything is not rosy. Privacy is one of the challenges eluding the act of collecting, storing, and dissemination of data online. The more we share the more someone is able to learn about us that even anonymized data is still revealing. Also, personal information out of your hands is vulnerable and can fall in the hands of those not willing to sign any understanding with a firm such as Facebook. Hackers maliciously attack public platforms(airlines, email providers, governments, etc) to collect data and resell to unregulated markets.

Is there a way data can be collected, stored, and used without subjecting the owner to vulnerability? I can’t think of one today but the future should be interested in this subject were much of the information we normally give out willingly will no longer be necessary to be granted access to a service.
