Abstract
Apparatuses, methods, systems, and program products are disclosed to securely erase user data using storage regions on a shared computing device. Memory stores code executable by the processor. The code is executable to configure a nonvolatile storage device of a shared device that may be used by multiple users but is exclusively used by one user at a time. The nonvolatile storage device has shared files storing system data and a data region storing user data associated with a user. The code executes to assign read-only privileges to the system region and read-write privileges to the data region before sharing the device with the user. Requests to write data to the nonvolatile storage device while the device is shared are serviced on the data region. When the user returns the shared device to the originator the code executes to erase the data region.
