As normal person If we have ever wondered if our phone is spying on us, we're not alone. One of the most hotly debated topics in technology today is the amount of data that firms surreptitiously gather about us online. We may well have shared the increasingly common experience of feeling creeped out by ads for something you recently discussed in a real life conversation or an online interaction.
This kind of experience has led to suggestions that tech firms are secretly recording our private conversations via smartphones or other internet-connectedd evices such as smart TVs, Amazon Echo or Google Home. Or that they are reading our private messages even when they are supposedly encrypted, as with Facebook’s
WhatsApp. If this were proven to be true, it would reveal a huge conspiracy that could do untold damage to the tech industry – which makes it seem somewhat far-fetched.
But recent revelations about the degree to which Facebook users’ data has been shared certainly won’t help to convince people that the big firms aren’t spying on us.
Yet, there is another, more compelling reason for the incredibly relevant ads we
see. Simply put, tech firms routinely gather so much data about us in other ways, internet companies already have an excellent idea what our interests, desires and habits might be. With this information they can build a detailed profile of ours and usealgorithms based on behavioural science and trends found elsewhere in their data, topredict what ads might be relevant to us. In this way they can show us products or services that we have been thinking about recently, even if we have never directlysearched for or otherwise indicated online that we would be interested in.
Firms invest heavily in gathering user data and do so in a number of clever ways.
Social networks and other apps offer to store and share our uploaded data for “free”while using it, and the content we access and “like”, to learn about our interests, desiresand relationships. And, of course, there is our search history, which can reveal so muchabout our current circumstances that Google data has even been used to spot the startof flu epidemics.
It’s not just individual sites or devices that monitor our online behaviour. A
massive ecosystem of advertisers and supporting companies is dedicated to trackingour activity across the internet. Sites commonly record what pages you look at bysaving a small file called a “​cookie​” to our browser. And your activity across differentsites can be matched by looking at our browser’s “​fingerprint​”, a profile made up ofdetails such as our screen size, the version of the browser we’re using and what plug-intools we have downloaded to use with it. Then, when we visit another website, an adfirm that has built a profile of ours based on our cookies and browser fingerprint canload a “​third-party script​” to display ads relevant to our profile.
Perhaps even more alarmingly, this tracking does not stop at online data. Techfirms are known to purchase data from financial organisations about user purchases inthe real world to supplement their ad offerings.
In simple ways they make a virtual profile of a person by collecting theredatabases, cookies, activities​. Then they use that information for their welfare weagreed with their privacy policy but is our information safe.
No it's not safe if it is stored encrypted it also be decrypt at a time so at that time what Internet Companies do.
