Identity Service Provider as Cloud Privacy Enabler.
The problem : Lack of trust in Cloud Service Provider.  
In addition: your Public Cloud File Sharing Provider  
may be requested to disclose to the 3-rd parties your
stored files in order to comply with a law, regulation
or compulsory legal request.

Existing Solutions :You should be aware that  
self-encrypting your files does not protect your
privacy since weak encryption pass-phrases can be
cracked and strong encryption pass-phrases can be  
key-logged.

Our Solution: Using our Multi-Enterprise  Rights
Management software we ensure that only persons
specified by you will be able to access your files
stored on the Public Cloud File Sharing Sites. We
emphasise that nor File Sharing Site , nor SentryCom
will be able to access these files .

These  data files  are stored encrypted (top secret
AES 256 bit) on Cloud Storage platform. To decrypt  
these  files - one  must perform strong authentication
vs. Identity Service Provider,  thus pass-phrase
vulnerability to malware , residing on client  desktop
is overcome. In addition - the person will be able to
open these data files only  if pre-authorised .
The demo's below show
that it is possible to
keep the functionalities
of popular file-sharing
sites , while protecting
privacy of file owners -
in convenient and cost-
effective fashion.
