What is a cookie? [↑]
It is very likely that many times you have browsed pages on websites that generate cookies. The following examples describe common situations of this type:
- You frequently enter a page where you have an account that requires a username and password. You can choose not to enter this data for each new session by allowing the operating system to save it. When you make such a choice, a cookie is stored on your browser device that can remain on it for years.
- There are websites that allow you to post comments after you enter your Facebook account username and password. If you accept the cookies, this data is stored in a cookie on your navigation device, preventing you from having to enter it again when you make a comment.
- When you visit Amazon-style online stores and accept cookies, by adding products to your shopping cart, a cookie is stored on your navigation device that “remembers” the products you selected so that if you visit other pages on the site that information is preserved. This cookie may remain stored on your device for several days depending on the store you visit.
In addition to the features outlined in the definition, cookies originated by a website have the following attributes:
- They have an expiration date.
- Their use must be known by the user, who has the option of accepting them or not.
- They are automatically stored in your navigation device, if you accept their use.
- You can block their storage and use by the website.
- You can delete them from your navigation device when you decide to do so.
- They do not collect your personal information stored on your navigation device because they are data files.
- Cookies do not identify the user, but rather a combination of user account, navigation device and browser.
- Each one needs a maximum of 4 kb of space on the navigation device.
What types of cookies are there? [↑]
A type derived from a concept and a property is the set of all the objects of the concept that satisfy an attribute of the property.
We use phrase: types of C according to P to name the types derived from a concept whose name is C and a property whose name is P.
We apply the following procedure to obtain types derived from a concept and a property:
- We select an important property that is applicable to all the objects of the concept.
- We determine a set of possible states of the property in the concept objects (attributes).
- For each attribute, we group in a class all the objects of the concept that have it. The sets thus formed are concept types.
Each criterion for the formation of types of a concept must satisfy the following requirements:
- The selected property must be applicable to all concept objects and must generate at least two different states when applied.
- Each state of the property must correspond to at least one object of the concept.
- Objects that have one property state must not have any of the remaining states, that is, types obtained from the same criteria must not share objects.
- There may be objects of the concept that do not correspond to any of the states considered of the property, that is, the types obtained from a criterion may not exhaust all the objects of the concept.
The following properties are important for the formation of cookie types:
- The time spent on the navigation device.
- Website that generates the cookie.
- The function of the cookie.
Types of cookies according to their time spent on the navigation device
For the property “time of permanence of a cookie on the navigation device”, we consider two possible states: 1) the cookie is deleted when closing the browser and 2) the cookie remains on the navigation device after closing the browser.
Some browsers, such as Google Chrome and Mozilla Firefox, can be set to clear all cookies when you close your browser. This is not taken into account in determining whether a cookie is temporary or persistent because the definitions of these concepts are formulated under the assumption that the browser accepts cookies and allows them to be stored according to the expiration time conceived by the website that generates them.
A cookie that prevents the user from having to enter data to access an account for each new session is an example of a persistent cookie because it remains on the navigation device after the browser is closed.
The types of cookies, depending on how long they remain on the navigation device, exhaust the full extent of the concept of cookie originated by a website which means that every cookie is either temporary or persistent: there is no third possibility.
Types of cookies depending on the website that generates them
For the property: website that generates the cookie, we consider two possible states: 1) the cookie is generated by the website to which the page visited by the user belongs and 2) the cookie is generated by an external website.
The cookies that correspond to the first state of the property, that is, those that are generated by the website to which the page visited by the user belongs are called first-party cookies.
When a user visits a website X and performs an action on X that leads to a second website Y that generates cookies on his navigation device, these are called third-party cookies with respect to website X.
Cookies that store the name and e-mail address of the user who writes a comment on a page of a website are examples of first-party cookies originated by this site.
Examples of first-party cookies are those that store the name and e-mail address of the user who writes a comment on a page of the site.
The cookie that stores a website user’s acceptance of cookies is also an example of first-party cookie of this site.
There are many examples of third-party cookies originating from a website. Cookies that may be generated when you visit a page on a website that has a YouTube video embedded are very common.
When you open the video you are in a similar situation to when you visit Youtube and therefore Youtube can generate cookies that are stored on your navigation device.
The following questions arise when relating these types of cookies with the types obtained according to the time spent on the navigation device:
- Are there any first-party temporary cookies?
- Are there any third-party temporary cookies?
- Are there any first-party persistent cookies?
- Are there any third-party persistent cookies?
The answer to each of these questions is yes, so that the set of cookies originated by a website can be broken down into the following four types:
- First-party temporary cookies.
- Third-party temporary cookies.
- First-party persistent cookies.
- Third-party persistent cookies.
Types of cookies according to their function
For the property: function of the cookie, we consider three possible states: 1) the cookie helps improve the user experience, 2) the cookie provides information for site improvement and 3) the cookie associates an affiliate ID with a user.
Cookies that help improve the user experience are called technical cookies, those that provide information for site improvement are called site management cookies, and those that associate an affiliate ID with a website user are known as affiliate cookies.
The following is more information about affiliate cookies.
Many companies that sell products on the Internet such as Amazon and Clickbank have affiliate programs.
Any user who wishes to become an affiliate of these companies must register. When you do so, you get a code that identifies you, called an affiliate ID.
The affiliate can select products to disclose them on their own website, social networks, Youtube, etc.
If the user has accepted the cookies, when he executes this action a cookie is generated that associates the affiliate’s ID to his visit so that if he buys the product, the affiliate receives a commission for the sale.
The affiliate cookies originated by a website are always from a third party and can be persistent or temporary. Cookies generated by Amazon are persistent; those generated by Clickbank are temporary.
Types of cookies according to the conjunction of several properties
You can obtain types of a concept by taking several properties simultaneously and considering possible states of these properties in the concept objects.
In this case the property of the type formation criterion is the conjunction of the properties considered and the possible states of this property are obtained from the conjunction of the states of the properties that compose it.
Types of cookies can be obtained by applying this idea. For example, if we consider the properties: 1) time spent on the navigation device and 2) website that generates cookies, the following four states result for the property that results from the conjunction of these properties:
- The cookie is deleted when the browser is closed and is generated by the website to which the page visited by the user belongs.
- The cookie is deleted when the browser is closed and is generated by an external website.
- The cookie remains on the navigation device after closing the browser and is generated by the website to which the page visited belongs.
- The cookie remains on the navigation device after closing the browser and is generated by an external website.
The cookies that satisfy respectively the above attributes are:
- First-party temporary cookies.
- Third-party temporary cookies.
- First-party persistent cookies.
- Third-party persistent cookies.
