Research Overview

Rushmore

State University of New York at Buffalo

Rushmore is a system that securely displays static or animated images using ARM TrustZone. The core functionality of Rushmore is to securely decrypt and display encrypted images from a trusted party on a mobile device.

Gesto

State University of New York at Buffalo

Gesto is a system that enables task automation for Android apps using gestures and voice commands. Using this system, a user can record a UI action sequence for an app, choose a gesture or a voice command to activate the UI action sequence, and later trigger the UI action sequence by the corresponding gesture/voice command.

Mimic

State University of New York at Buffalo

Mimic is an automated UI compatibility testing system for Android apps. Mimic is designed specifically for comparing the UI behavior of an app across different devices, different Android versions, and different app versions.

Reptor

State University of New York at Buffalo

Reptor enables open innovation in mobile platforms. Our technique allows third-party developers to modify, instrument, or extend platform API calls and deploy their modifications seamlessly. The uniqueness of our technique is that it enables modifications completely at the app layer without requiring any platform-level changes.
