Welcome to PSAL, Drexel University's Privacy, Security, and Automation Laboratory.
We research topics at the intersection between artificial intelligence, privacy and security, and human-computer interaction.

Authorship Recognition Study - Participants Needed
This should take between 30 to 50 minutes of your time. The goals of this research are to discover how well current methods of authorship recognition perform when faced with with human adversaries who are deliberately trying to circumvent them, and to develop that can be used to study both future methods of authorship recognition and methods of circumventing them. A corpus of the results will be released to the public to help all researchers. Thanks for your help.
- We have released our first adversarial stylometry corpus. It contains 12 of the 15 authors who made up the corpus used in "Practical Attacks Against Authorship Recognition Techniques."
