You can work on biometric data security. Review previous work, and Find out the limitations of previous research. discover and research technical aspects of the biometrics system, and consider the biometrics data's security. Basically, it depends on your research methodology and what problem you want to resolve.

Dear Rahila N Ameer. One area of ​​research that appears to be very interesting and novel is the application of Delaunay triangulation or Vornonoi polygons to fingerprint identification. I suggest you consult: Bebis, G., Deaconu, T., & Georgiopoulos, M. (1999, October). Fingerprint identification using delaunay triangulation. In Proceedings 1999 International Conference on Information Intelligence and Systems (Cat. No. PR00446) (pp. 452-459). IEEE. https://link.springer.com/book/10.1007/978-3-030-83624-5#toc

Dear Rahila N Ameer.

Some applications of the Delaunay triangulation in "Graphical Authentication" can be consulted at: "Weak PassPoint Passwords Detected by the Perimeter of Delaunay Triangles," Security and Communication Networks, vol. 2022, Article ID 3624587, 14 pages, 2022. https://doi.org/10.1155/2022/3624587 and (2022). Weak PassPoint Passwords Detected by the Perimeter of Delaunay Triangles. Security and Communication Networks, 2022. https://doi.org/10.3390/s22051987

In case you are interested in the topic, the mentioned reference, Bebis, G., Deaconu, T., & Georgiopoulos, M. (1999, October), is just an example and starting point, since there is more recent work on this topic than you could consult.

Biometric security is a rapidly evolving field with various working areas and ongoing research. Some of the current focus areas within biometric security include:
