The primary issue here lies on the client-side, as the server remains unaware of the typed information until the form is submitted in its entirety.
While it is theoretically possible to track every keystroke using JavaScript, the process of reconstructing messages server-side, storing data effectively, and creating a user-friendly player poses a significant challenge.
Moreover, there are notable security risks associated with this method. What if a user accidentally pastes sensitive information like a credit card number and then deletes it? How would copy/paste functions be managed?
Overall, while technically feasible, implementing this approach is complex and raises serious concerns regarding security and privacy.
Should you choose to proceed with this, the necessary steps include:
- Monitoring every keystroke inputted
- Sending this data to the server with precise timestamps, either upon form submission or continuously using AJAX
- Storing the keystrokes in a database linked to the user's unique ID or form URL
- Integrating this keystroke data with the form's actual functionality
- Developing a page capable of reading and replaying the entered keystrokes on the corresponding page
- Executing the recorded keystrokes
Clearly, this process demands comprehensive effort and attention to detail.
