Data interception from Android devices and voice synthesis
View/
Abstract
This dissertation examines how applications on Android mobile devices can access the user's personal information without them being aware. The implementation of an application called "VoiceRecordingThesis" is presented, which accesses the microphone of the mobile device and uses it for reasons other than one may consider obvious or expected. The paper presents the ways in which the collected data can be processed and by using an available speech production application there can be generated additional harmful data for the user. Voice synthesizers can produce untrue information that could harm their public image and private life. In addition, another application called "HiddenCameraThesis" was implemented and can access the camera without previewing the image to inform the user that the photo was taken.
The aim is to understand the risks involved in the use of mobile applications as well as the vigilance of users who are easy to grant access to mobile capabilities, such as the use of microphone and camera, which are examined in detail in this study.
