Protect sensitive apps from tampering GitHub repository

February 2017 to June 2017


IvyLock is a program that allows you to lock individual programs on your PC behind password / biometric authentication. I wrote this for the Technology Student Association competition in high school.

On Windows, it isn’t really possible to intercept a program before it launches without getting into nasty kernel level-stuff and essentially pretending to be either a debugger or an antivirus. Instead, this program works by watching for new processes and instantly suspending any processes that require authentication until the user enters the password.

At the time, there was no convenient way to access Windows’ biometric APIs from a WPF app, so I wrote a native module in Microsoft’s bizarre C++/CX variant to get access to Windows Biometric Framework.
