The techniques utilize an authentication process to authenticate the user to view protected data and an image monitoring process to monitor the field of view of the image detection component. When a user requests access to the protected data, the authentication process is activated. After a user is authenticated, the data may be displayed and an image monitoring process is activated and may use the image detection component to monitor the field of view to determine whether the user is actively viewing the data or that an additional person is in the field of view. When either event is detected, the protected data is concealed at the display of the user device.
