dr. D.K. Sarmah MSc (Dipti)

Dipti K. Sarmah is a Docent in the group Semantics, Cyber Security and Services (SCS) in the Department of EEMCS at the University of Twente, The Netherlands.

She worked on developing a high-capacity and robust image steganography method using nature-inspired optimization techniques. The major findings of her doctoral research have been published in the Journal of Information Security and Applications and Information Sciences. Her research interests span a variety of topics, including the study and analysis of human behavior for cyber security, the fields of steganography and cryptography, and their practical applications. She also worked as a Microsoft patent analyst and has experience in performing prior art searches, infringement analysis, and validity/invalidity analysis. 

In addition to research, she also enjoys teaching. She received her University Teaching Qualification Diploma from the University of Twente. Also, she likes supervising master's and undergraduate research projects that focus on real-world applications relevant to her research field. Here are a few examples of the projects she supervised at the University of Twente. 

1. Network Authentication of Images to Stop E-Skimmers.
2. Hide Your Pattern Password From Shoulder Surfers
3. Studying Human Behavior to Prevent Successful Spear-phishing Attempts
4. A Serious Game on Image Steganography Training For Students in Higher Education

The motivated and interested researchers and/or students who wish to work in a similar area are encouraged to get in touch with her.
