COOKIES  What are they and what are they for? ▷ 2020

“We use our own and third party cookies to improve our services”. You have surely read this text hundreds of times when you visit a web page. That is because ePrivacy, a Privacy and Electronic Communications Directive for the EU issued in 2009.

It is nothing more than to warn you that the web page you are visiting uses certain programs that will be installed in your browser in order to detect your activity and preferences. At first this sounds like a good thing, but many times it is not so much.

Pay attention to the following post that we have prepared. These paragraphs will help you to know what this is about “Law of Cookies”. Not without first knowing what the famous computer cookies are. Let us begin!

What is a Cookie and what is this type of file used for?

What is a Cookie and what is this type of file used for?

A Cookie is a software developed by companies or people who They are used to collect information from the user while browsing on a certain website. There are different kinds of these computer cookies.

There are those that are used so that the page works technically well. That is to say, They serve to save the preferences that the navigator has so that when you go back to that website, you don’t have to re-enter all your details. It is very useful to improve the user experience, since the information about email, language and other information necessary to log in in the future is saved.

The other type of Cookies that exist It is the one that does not serve to improve the functioning of the web. These are used to obtain user information and then use this data to advance advertisements that are often generated even invasive. But this is not the only problem that “cookies”, since Cookies that are used to track and obtain private information can also be installed in the browser and then these data will serve to steal user data and use them for criminal purposes.

How do cookies work? Main features

Cookies are installed in the browser, which allows, in a fast way, to save different data related to the choices that the user makes when visiting a certain site. In this way, they can be used for technical purposes or for economic or criminal purposes.

These small files have as their main characteristic their expiration. In other words, Cookies disappear from the browser when the user delete manually or it does it automatically with a special tool. Or, at the moment when end user session or when it exceeds a deadline established in the programming codes. Those that can be minutes, months or years.

Its use is especially intended to identify the user. When the person visits a page hosted on a certain server, it controls the identity of the navigator through the records previously established by Cookies.

Another of the characteristics that a “Technology cookie” is that can be easily tampered with by intruders. In other words, people with more experience in computing can access these small files saved in the user’s browser and modify the contents. In this way, it generates adverse results, both for the website and for the person who is browsing.

They do not take up too much space on the storage disks nor do they modify, in principle, how the browser works. But as time passes, a significant number of files are generated that forge slowness in computer or mobile operations.

One of the most important limitations that Cookies have is that They do not identify the person, but rather work according to user accounts. That is, if the same person has 2 or 3 browsers on the same computer that they use frequently and access the same sites, in each of them you will have a multiplicity of cookies. This happens because they cannot identify that it is the same person. This also increases a significant risk to the user’s private data.

What are the risks of allowing websites to use Cookies in our browser?

What are the risks of allowing websites to use Cookies in our browser?

Among the risks that Cookies have the theft of them is found. This happens due to their operation since they work between the server and the computer sending and receiving these software for identification.

The problem arises when browsing protocols that are not secure, as is the case with HTTP. In these situations, the user’s personal data can be seen by other participants who can listen to the server-computer conversation through a “Packet sniffer”.

This serves so that, by altering or stealing the user’s preferences, can create a benefit of a third party without authorization of the person who owns the private information. You must bear in mind that, if you use encryption of the information, this protocol will not be efficient since there will be servers that can receive the data without authorization.

Other dangers that exist when information is sent to the server and are modified along the way Cookies is that they are hosted on the hosting where the site is hosted and from there make the disruptive changes.

What is the relationship between the RGPD Law and cookies on web pages?

What is the relationship between the RGPD Law and cookies on web pages?

The Cookies law, colloquially called the a Directive 2009/136 / EC of the European Parliament, effective as of the end of 2009, establishes that Internet sites that use Cookies must guarantee the protection of users’ private data.

With this progress is made for the installation of Cookies the express authorization of the users is required, except for those that are necessary to improve the user experience, such as the tools used to record information about language, login, password, etc. But as we know, these software not only contain technical Cookies, but there are also those programs that are not necessary, such as the Tracking, segmentation, analysis and social media cookies.

Since this Directive did not make clear some specific situations and left the implementation according to their laws in the hands of the member states of the European Union, was established in May 2018 European Data Protection Regulation (RGPD), also called EPrivacy Regulation.

With this new regulation, which is mandatory for all member countries of the EU, it is established that the user needs to give an express consent to the acceptance of Cookies that are not technically necessary. In addition, consent is not expressed only by having a box checked, but there must be an express authorization for the navigator to know who their private data will go to and for how long the Cookie will last on their computer. This arose from established jurisprudence from a judgment of the Court of Justice of the European Union (CJEU).

In October 2019 the CJEU ruled on the installation of Cookies leaving definitively and firmly its regulations from the previous year. Therefore, at present it is necessary for Internet sites to have precise information on those text files that are not necessary and that are part of these computer cookies and do not serve for the proper functioning, neither the website nor does it improve the user experience.

In this way the Opt-in technique is created. With which Cookies are not installed immediately when a website is openedInstead, the user is the one who decides on the storage of the files. Therefore, the “Opt-out” which refers to the installation of Cookies from the beginning, the user being able to claim after this process occurs.
