 How does eListas use cookies?

If you have not read yet our Privacy Policy, we suggest you do so, since the way eListas uses cookies is according to such policy.

What is a cookie?

In short, a cookie is a small piece of information placed for a determined amount of time on your computer by a web server when you load a page from such server. That by itself is harmless. It's the type of information that may be stored what causes that some users may not trust the purpose served by some cookies.

Why cookies aren't so popular?

Cookies are not a bad thing. In fact, they can be quite useful to the users. Cookies got a bad reputation, first because in some cases they are somewhat intrusive cookies, that is, they are used to learn more about you, your habbits, and in short, about things that you may not want to reveal to third party sites and that don't help in any way to your Internet experience.

Also, cookies may also pose a security risk, as sometimes the information stored in them is sensitive information, such as your login access to a particular site, and should that information be obtained by a third party (not you nor the server that placed the cookie on your computer) could be used to access your account on a particular web site, etc.

How does eListas use cookies?

The only cookie used by eListas is not used to investigate your habbits or anything like that. Its only purpose is, once you've accessed your account at eListas, to remember who you are for a specified amount of time, so that you can use eListas without having to sign into your account every time you go to a different page in our site.

This cookie remains active until the system detects 20 minutes of inactivity, (or for 6 months, should you select the "Remember me" box when you sign into your account), or until you manually select the Sign Out link to exit your account.

For more information regarding how to manage the time and way in which eListas stores this cookie, visit the Storing your access information on your computer page.

Can someone else obtain my cookie?

First of all you should know that eListas designed its cookies management system assuming that such cookies could be obtained by a third party, who could try to decypher them and try to access your account.

In any case, obtaining the information stored by eListas in your cookie is not an easy task, to begin with. As far as we know, there are only two ways in which someone could access your cookie.

One way is if someone is eavesdropping the information being transmitted between your computer and our servers. Although an experienced "hacker" with the right "tools" could do this without a lot of difficulty, it is not a very easy task. eListas considers this type of espionage to be an illegal activity, and will work with law enforcement agencies in prosecuting anyone suspected of illegally obtaining the information that travels in and out of our servers.

The other way is when someone has physical (or network) access to the computer you used when signing into your account at eListas. Cookies are files stored on a specific file and directory on your computer, and if such file or directory are not protected, anyone with access to that computer can open, read and retrieve your cookies.

And of course we cannot ignore the possibility of someone finding a new security hole in our browsers or operating systems that would allow a third party to access our cookie files.

NOTE: When a server assigns you a cookie, it can do it so that the cookie could be accesible by any other server, although almost nobody uses this type of cookies due to the security risks, and pretty much all servers assign cookies that can only be returned back to the server that originated them.

If someone obtains my cookie, could he gain access to my account?

As we mentioned earlier, the cookie management design used by eListas assumes that such cookies could be obtained by a third party, who could try to decypher them and try to access your account. So, how does eListas protects the information stored in the cookies?

The cookie stored by eListas is made up of several pieces of information, which is then encrypted several times by one-way algorithms, that is, the data can not be decoded except by trial and error. By applying these one-way algorithms, it is guaranteed that it would be impossible to decode the information just by obtaining the cookie, even if the hacker knows the encryption algorithm.

So, is this method 100% secure?

It is hard to imagine something that it's 100% secure, especially on the Internet.

In this case, we have developed a system that, although it cannot be declared 100% secure, it is extremely difficult to break. We have been in business since 1999 and at the time of writing this (January 2005) there has not been one single case of a cookie being stolen and successfully used to access someone else's account.
