MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202541112615 A) filed by S. Prakash; S. Santhosh; R. Surya; S. Sanjaypalani; and R. Vivin, Coimbatore, Tamil Nadu, on Nov. 17, 2025, for 'graphical password to avoid shoulder surfing.'
Inventor(s) include S. Prakash; S. Santhosh; R. Surya; S. Sanjaypalani; and R. Vivin.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "Traditional authentication methods, such as numeric PINs and text-based passwords, are highly vulnerable to shoulder surfing attacks, where unauthorized individuals steal login information by observing the user's input. This project proposes a graphical password authentication system to enhance security and usability in A TM applications. In the proposed system, users authenticate themselves by selecting or interacting with images on a touchscreen interface instead of typing nlllneric PINs. The images are randomly arranged each time the user logs in, making it nearly impossible for onlookers or hidden cameras to reproduce the correct password sequence. Additional features such as gesture-based interactions (tap, drag, or rotate) further strengthen protection against observation-based attacks.
