Ever felt like the internet knows too much information about you? Do you feel unsafe and no longer in control of your own privacy online? Do you sometimes wonder why the ads that you encounter now seem to be more and more connected with your digital activities?
Well… you’re not the only one.
On Norton’s 2021 Cyber Safety Insights Report, 78% of responders say they are concerned about their privacy online and 82% of those have taken at least one safety measure to protect themselves from cybercrime.
Due to the increasing need of the public to feel more secured on the internet, tech giants like Google and Apple have done some massive changes these past few years to show their willingness to cater to the critical demand for increased internet privacy. In fact, some of these modifications are being considered as game changers, re-shaping not only the way their services work, but even the future of the internet.
One of the most significant decisions related to internet security that Mozilla, Apple and Google had to make recently was the prohibition of third party cookies on their browsers Firefox, Safari and Chrome respectively. Now, you might be wondering why this is a big deal, or what third party cookies even are, or how this big change will affect you. This blog will answer your burning questions about this issue. So quit wondering, and continue reading!
To better understand the importance of third party cookies, we first need to explain what first party cookies are.
Everytime you go to a website, first party cookies are created by the domain you’re visiting and directly stored on your computer. These cookies track and record your activity within that domain only (e.g. language preference, shopping cart items, username/password). So the next time you visit the same website, it remembers you, delivers a more personalised browsing, which provides a better user experience. Pretty simple and safe, right?
Not until third party cookies come into play.
Third party cookies are also stored on your computer when you visit a website. However, they are created by an outside domain (not the website you’re currently in) – hence the name ‘third party cookies’. Usually installed on websites by advertising companies, these cookies are used to track your activities across ALL websites that you visit, unlike first party cookies that only track your activity within the same domain.
Third party cookies serve as a very powerful tool in digital advertising. Since it has the capacity to follow you around the web and record the activities you do online (eg. the websites you visit, your personal interests, your online purchases, etc.), advertisers can use those data to create a detailed consumer profile and serve the ads that you would most likely be interested in, across all digital platforms that you access. In fact, third party cookies are now being widely used for cross-site tracking, ad retargeting, data research and analytics. However, if you ask the original creator of digital cookies, Lou Montulli, his mechanism was not supposed to be used the way it is being used today.
Going back to third party cookies as it is today, here's a sample scenario:
Jenna searched for a certain laptop model on Buybuy.com but did not make a purchase. The next day, she sees a Buybuy ad of that same laptop model while reading an e-mail. The same ad also popped up while she was browsing a different website (not owned by Buybuy). This means that Buybuy.com uses a third party cookie which recorded Jenna’s activity to serve an ad about their product that she was previously interested in. This is an example of Ad Retargeting.
Brilliant, right? But is it safe?
The security issues surrounding third party cookies has caused the three dominating tech companies to rethink whether they should still allow its use on their browsers (Mozilla, Apple and Google). As a matter of fact, Firefox and Apple have already started gradually eliminating third party cookies on their platforms a few years back.
Here is a simple timeline of most recent tech releases that these two companies executed relating to third party cookies and cross-site tracking:
With Apple and Mozilla bravely implementing ground breaking rules relating to third party cookies, Google is expected to follow suit. However, with Chrome having the top spot as the most-used internet browser worldwide owning 65.13% Market Share (as of July 2021), their move will not only be the most anticipated, but also the most consequential.
Google’s current predicament is finding a balance between protecting people’s privacy and providing sustainable technologies and tools that could help companies and developers thrive in the business industry. Last year, Google has announced their plan to end its support for third party cookies on 2022 to give ample time for public discussions and further assessments. But just recently, the company took a step back and announced the delay of this big milestone.
Through an official statement, Google said that Chrome will phase out third-party cookies over a three month period, starting in mid-2023 and ending in late 2023.
Though Chrome still supports cross-site tracking and third party cookies by default, users still have the option to clear, enable, and manage cookies by accessing their browser settings.
