Drawbacks of Cookies
Even though cookies make our lives easier on the Internet, they come with drawbacks as well. Some of the major ones are listed below:
- Shared Machines: Most people share their computers with their friends and family. As a result, a cookie set during the usage of one user may not be appropriate for the other user using the same machine. For example, when a new user revisits a shopping website such as amazon.com, he/she will be presented with all the information belonging to the previous user such as order details, shipping address and other personal preferences. This may cause annoyance to the new user as he/she may be required to change all the preferences once again to match personal requirements. Additionally, the exposure of previous user’s preferences and settings to the new user may raise security issues.
- Accidental Deletion: In many cases, cookies can get erased accidentally when you clear your browsing history or use a third party cookie cleaner program. When this happens all your stored settings and preference gets lost and the website treats you as a completely new user.
Privacy Issues
Since cookies are capable of tracking a number of user specific information such as online behavior and personal preferences, they can be used to hamper the privacy of users. A website may use cookie information to display related advertising products based on your previous purchase. For example, Google often stores and uses your search keywords to display matching advertisements on all its partner network. Some sites are also known to have engaged in selling the cookie data to third parties which seriously hurts the privacy of individuals.
