摘要:
A computing device is described that utilizes two file systems to enable sensitive data stored thereon to be deleted automatically, quickly, and discretely when the computing device is in a risky environment or context or when data protection has otherwise been activated. A first file system on the computing device manages a first memory area that stores non-sensitive data while a second file system on the computing device manages a second memory area that stores sensitive data. Only the first file system operates to receive data requests from other processes executing on the computing device. In a first operating mode, the first file system interacts with the second file system to ensure that both non-sensitive and sensitive data is returned in response to data requests. In a second operating mode, communication between the two file systems is disabled and the second file system deletes the sensitive data.
