Keystroke dynamic

Why do you think , key stroke dynamics and graphical passwords are not suspectible to brute force ? keylogging and phishing ? 

Text passwords are rigorously studied and several methods are developed for attacks. 

Graphical passwords are relatively new and number of attacks also less. As of now, this method is more secure. It is finding more applications. You may refer the following link for more details.

Dear Sashank,

Thank you for your interest. Keystroke dynamics is a biometric feature. So it is less prone of those attacks. 

Now consider the case of graphical password. Here we can create a very large password space in comparison to text password space. So it is not easy to carry out a brute force attack. In graphical password scheme either we select some images or click on some points within an image as password. So there is no use of keylogger since there is no keyboard events. To mitigate the attack of phishing it is required to capture the screen. In case of graphical password scheme it is possible to create different log in screens for different users. Look of login screen will be based on the image selection during registration. So you can understand that it is also secure against phishing.

Hope this explanation is enough.

as per my knowledge....keystroke dynamics is a better option....
