There are many details about cookies. Almost all existing web pages recognize the policy regarding their cookie policy and slowly as we introduce ourselves to the Safari security measures and will eventually learn about cookies. But we know what cookies are?
What are cookies?
Let's start with your name. Cookies, which we can translate as "cookies", have their signature origins in 1979, there C A standard library referred to magic cookies. These Magic cookies The pieces of information have been changed between the two apps and apparently have no clear meaning.
Let us explain. We can understand cookies as a ticket. For a game, for example, tickets are sold and, upon payment, a paper ticket can be obtained. The features of this ticket: its shape, color, size, shape or detail printed on it, by themselves, are unrealistic, the important thing being that when we bring it to the function gates, the responsible employee recognizes it as a ticket. Cookies are of the same quality, the importance of cookies is that they are unique.
Cookies?
Cookies serve many purposes on the web, the main being to allow us to access various services. But there are other functions that depend on cookies, such as seeing wikipedia in Spanish and not in German, or those when we visit a particular page we always see it in black mode activated
Other uses of cookies, used for them, are, unfortunately, not made in the first place, to track our browsing habits. So, in particular, cookies have gained a certain reputation. We'll talk about that soon.
How cookies work
Let's assume that we are the speakers at the convention. After our excellent presentation there will be a meeting and a response time and we want to be able to respond in a very personal way and to use the name of the person asking. One way is to remember all faces and all participants' names, another option is to use cookies. Let's do it this way: when meeting participants begin signing up at the door we gave them a small number card, the number will be random and unique for each participant. As well as the delivery of a number to our participants, we note in our textbook the correspondence between the number presented, one's name and other personal information.
Yes, we already have cookies brought in by browsers, I say to participants. When a question and answer period begins, we ask our users to indicate the number of cookies (their cards), above the question. While hearing the question let's do a a quick search of our notebook to find that cookie number and answer the question using the information we have written down.
Web pages do the same. In the example we just saw there will be a website and the participants of the meeting will be guests. When we visit a website, it gives us a random cookie identifier, next to that directory, for your records, write down, for example, our language preferences. The next time we visit the web, the browser, for example Safari, will extract the identifier and the browser says: "ah, this visitor wanted my page in Spanish."
Many uses and misuse of cookies
As we can see, cookies reach as far as we have mentioned, a the most direct and elegant way web pages. So why did they get a bad reputation?
Before we get into this topic, let's go back to the example of our convention. For example, we care about distributing cookies, but what if we ordered it from a third party? Well, actually, but, if we think this third party is special in this service, it will mean that it will serve many people, that means at many meetings. In this case the situation is changing.
People at our meeting get a ticket, but this ticket also applies to other meetings that take place over a week in the same city. With this valid ticket, a third party company is able to find out Which conferences have a cookie (person) that you attended And from there, for example, you can create advertising profiles. There, we abuse cookies. Let us see you through an example.
Many internet pages have a Facebook "like" button where we see the faces of other people who love the page. The problem is that this button is connected to a cookie, that is, for the first time ever to open a website with "Like", Facebook (a third party company) saves the cookie in our browser. When, next, we visit pages with this "Like", Facebook reads our cookie again not knowing what conferences we attended, what pages we visited
Google, and cookies included by its advertising activities, are also present over 90% of web pages, achieves the same result. And you'll say, "oh, I don't have a Google or a Facebook account", because it doesn't matter, tracking happens exactly the same.
In all of this, it is important to distinguish between cookies on the page we are visiting and third party cookies. The cookies that this page actually provides us are available on the website we visit, on time third-party cookies include almost the entire Internet.
What can we do about it?
What we can do There is a lot, in fact when we use Safari and our device we use it PC / iPadOS 13.4 or MacOS 10.15.4 third-party cookies are automatically blocked. Other options are to use certain apps to block cookies or stop our browser from accepting it.
Another option always clear the history of our browsers, because as a result cookies cookies, and third-party services, that have been stored in our browser are terminated. Remember to delete history on our iPhone or iPad that we will access Justification > Safari > Clear website history and data. On our Mac we will make it from the menu Safari > Clear history > All history > Clear history.
In the end, the most important thing to be clear is that cookies themselves are not good, rather, but like many things, they can be used, at least, to be questionable.
