Thanks in advance

Your can capture images using the camera only, no way to acquire data from the screen itself. So I guess you need to make your system login using face recognition. However this will be easy to fake (take a picture of an existing photo of your president and log on his account)...

Other than this, to send an image or more generally data to a server using HTTP, have a look at the HttpClient class from Apache.
