A survey by Andy Grant investigated the practices of major app developers with regard to data storage on Windows Phone 7. As more people use mobile devices for sensitive tasks such as, online banking and password storage, the data stored on the device increases in value. With each new mobile platform there are more opportunities for a mobile application developer to store data in an insecure manner.
This paper looks at how popular Windows Phone 7 apps address data storage with a focus on the platform’s initial lack of data protection APIs and how that inﬂuenced the type of and manner in which data was kept on a user’s device.
