Scientists Propose Identifying Users by Typing Patterns

The startup TypingDNA has launched a free extension for the Google Chrome browser that allows users to be identified by their typing patterns instead of using two-factor authentication when logging into websites. This was reported by TechCrunch.

How Typing Pattern Identification Works

Typing pattern identification is a behavioral biometric authentication method that analyzes a user’s unique typing habits. The main factors include typing speed and the duration each key is held down. Previously, TypingDNA released an API for integrating this authentication method into websites. With the new Chrome extension, users can now access many services—such as Amazon Web Services, Coinbase, Facebook, and Gmail—using this technology.

Replacing Two-Factor Authentication

The extension replaces the second step of two-factor authentication, which typically requires a code sent to a smartphone, making the login process faster. The extension displays a one-time access code directly on the computer screen and then automatically analyzes the user’s typing pattern as they enter their username and password.

Accuracy and Future Improvements

The program currently works with 99% accuracy if the user types on the same keyboard. Scientists are now working to increase this accuracy to 99.9%.

Alternative Access Methods

Recently, researchers from the University of Florida and Bloomberg suggested using everyday objects—such as a bracelet, water bottle, or pack of cigarettes—as access keys.
