Hi everyone,

Does anybody know if there is some protected memory space in android,
that eventually can be used for storing confidential information that
cannot be either copied or accessible by the user, malware or
intruder?. The question is focused on how the android O.S. manages the
hardware utilities of a mobile phone.

One alternative that I consider as valid is the use of the SIM card
for these purposes, given that this is a trusted platform module.
However the SIMtoolkit offers by android is limited and does not
support to perform actions of reading and writing of data by
applications (just modification of contact lists and state of the SIM
card).

Any hint or idea, always will be welcome!
