If you visit websites alot you might have see this word and wondering what is cookies and their types and wondering if they are safe.
so stick on us and we will get through it together
What are cookies
Cookies (also known as web cookies, Internet cookies, browser cookies, or HTTP cookies) are small data blocks created by a web server
while a user is browsing a website and stored on the user’s computer or other device by the user’s web browser.
Cookies are stored on the device
They are used to access a website, and a user’s device may receive multiple cookies during a session.
They help news websites remember the articles you’ve already read.
But, in the end, they don’t accomplish much: most of us simply click “yes” and move on. If you reject cookie tracking, the website may not function properly. However, most of the time you can simply continue browsing. They’re similar to the annoying pop-up ads we all ignore when we’re online.
These cookie disclosures are also a symptom of one of the internet’s long-standing and fundamental flaws in terms of online privacy and who can access and resell users’ data, and thus who can use it to track them across the internet and in real life.
Types of Cookies
Cookies of various types track various activities.
So without further do lets get t understand different types of computer cookies
1. First-party Cookies
The website that the user visits sets first-party cookies.
First-party cookies collect information that is used to calculate pageviews, sessions, and the number of users.
Publishers have primary access to data collected through first-party cookies.
They then share them with advertisers or ad agencies for ad targeting.
Aside from that, analytics tools, such as Google Analytics, use first-party cookies to understand user behavior and present it to the publisher in tabular or graphical form.
An example of a first-party cookie is when a user signs into an ecommerce website, like Amazon. The web browser will send a request in a process that provides the highest level of trust that the user is directly interacting with Amazon
2. Third-party cookies
Third-party cookies are set by domains that the user does not directly visit. This occurs when publishers include third-party elements (such as a chatbot, social plugins, or advertisements) on their website.
Third-party cookies, once installed, track users and save their information for ad targeting and behavioral advertising.
Like the previous example, third-party cookies are used when a user shops on Amazon. They may look at a few items and spend some time on the product pages. When a user decides to buy only one item, the brown hat over the brown shoes, they may later receive emails and other advertisements for the brown shoes they looked at but did not buy. Even if the user closes their browser and logs out, the tracking data will remain on their computer.
3. Persistent Cookies
A persistent cookie is a data file that allows websites to remember user preferences, settings, and information for future visits. Persistent cookies allow for easy and quick access to familiar objects, which improves the user experience . A persistent cookie is also called a stored cookie or a permanent cookie.
Persistent cookies, remain on the user’s browser for an extended period of time. In general, persistent cookies must have an expiration date that can range from a second to ten years. The screenshot above is an example of persistent cookies with an expiration date.
Try this to see if your browser has persistent cookies. Close the tab(s) and restart your device if you are logged in to Gmail in the browser. When you restart your device, open the same browser and visit the same service or account (Gmail); if you are still logged in, you have persistent cookies saved on the browser, which Google mail service has dropped.
4. Secure Cookies
Secure cookies are HTTP cookies with the Secure attribute set, which restricts the cookie’s scope to “secure” channels.
Only HTTPS websites can set secure cookies, that is, cookies that contain encrypted data. Secure cookies are typically used on e-commerce website checkout or payment pages to facilitate safer transactions. Similarly, for security reasons, online banking websites must use secure cookies.
5. Session Cookies
A session cookie is a file that contains an identifier (a string of letters and numbers) that a website server sends to a browser for temporary use for a set period of time. By default, session cookies are enabled. Their purpose is to make individual web pages load faster and to improve website navigation.
Session cookies are cookies that expire either immediately or within a few seconds of the user leaving the web browser. These cookies are used by e-commerce websites, among other things, to remember the product the user placed in the cart, to keep users logged in, and to calculate each user session for analytical purposes.
for example, if an e-commerce website does not use session cookies, the items added to the cart will be removed by the time the user reaches the checkout page. And the server will forget about the user and treat him or her as if he or she were a completely new visitor.
Are cookies safe?
Cookies cannot, under normal circumstances, transmit viruses or malware to your computer. Because the information in a cookie does not change as it travels back and forth, it has no effect on how your computer operates.
In addition to privacy issues, cookies have a few technical shortcomings. In particular, they frequently conflict with the Representational State Transfer software architectural style, they can fail to reliably identify users, and they can be applied to security attacks.
