A cookie is a text file composed of alphanumeric characters that are stored on a user’s computer when a website is accessed. Cookies are also called by other names like browser cookies, HTTP cookies, and web cookies. The browser uses a cookie to navigate the website more easily. A cookie can be used for log ins, language settings, shopping cart contents, themes and more features that use text data.
Certain cookies have dates of expiry. These may be saved by the browser and deleted as the expiration date passes. Other cookies do not have expiry dates. They are automatically deleted as the browser is terminated. Cookies help a website to deliver improved services, although cookies in themselves do not hold information.
Cookie files include the name of the server, its duration, and the cookie value, and are stored in the browser’s cookie file. The cookie value is a randomly produced number that makes one cookie distinct from the rest. This value helps the server that created the cookie to recall the user when he or she comes back to the site, or to navigate from page to page.
Unlike a virus, a cookie is not an executable file, meaning that it cannot reproduce itself. However, it can be a privacy concern in some situations. A browser has a system that sets and reads cookies so a cookie can be used as spyware, like the “zombie cookie” or an “evercookie”. As spyware, a cookie can be used to track computer activity. This is why users are given the option to choose whether or not to accept cookies.
A cookie itself is not dangerous on a computer. Its role is just to help the website to identify the user and summon up his or her information. For example, a website may ask the user to input his or her name the first time he or she visits the site. The cookie then tells the server who the user is every time he or she returns to the website. A user should not wonder why his or her name would appear on the “welcome” page the next time he or she returns to the same site.
Privacy risks can be an issue in the use of cookies. All personal information uploaded by a user will be remembered by the cookie. This can expose the user to the possibilities of identity theft or computer hacking. This is one of the reasons why some users would want to remove cookies kept in their computers.
Cookies can be removed in various ways, depending on the user’s browser. However, there are three general steps involved in doing such an action:
First, on the browser, go to “Tools”.
Second, select “Internet Options” or “Options”.
Third, under the “General” tab, choose “Delete Cookies”. This may necessitate a combination with other functions. The “Browsing History” may be used where cookies may be deleted together with temporary files. The user can choose to delete all items or just the cookies in there.

It’s not just about cookies! Online privacy can be compromised by a number of issues. One problem is IP addresses. Change your IP address by using an anonymous Proxy server to mask your IP address and defend your Internet identity. For more information about using a Private Proxy please visit our blog.
