If you are using a public computer, the chances are high that your personal information might be at risk. There is a probability that a key-logger might be installed on the machine. Key-loggers are programs, normally used for malicious intends, which log each key stroke of the keyboard. For instance, if you open your computer and type in a url and then enter your username and password, all these would be stored in a special file generated by the key-logger. These programs run in hidden mode and you won’t be able to realize that they are working behind your normal applications.
So, how do you protect your information from these malicious spywares? A nice way would be to confuse the person reading your personal information. Here are a few tips you might want to follow:
- Before entering a URL, open the drop down list of a browser to see if the website is present. Open the website by clicking it. That ways, the key-logger won’t be able to record the website you are browsing.
- Don’t enter your username, password, credit card numbers or any other secure information directly on the text boxes provided for these. Instead, open a notepad file and type some random text. Between this random text put your passwords or other information split into multiple parts. Now copy-paste these parts of your information on the website. It would be almost impossible for the person reading the key-logger file to decode any of your information from this file.
- A number of banking websites, like icicibank.com and hdfcbank.com have introduced the concepts of virtual keyboards. These also allow a sound level of protection as you need to select your password by selecting the alphabets using the mouse buttons. Always use them for enhanced security.
P.S.: Public computers still don’t provide a very high security level. There might be machines which are monitored through virtual networks and video recording of your sessions could be made easily. So, always try to avoid sharing your private information on these systems.
