  The paper discuss possible cloud-based
Information Rights Management (IRM) model extension with
enhanced accountability for both a sticky policy and an attached
data. This work compliments research on secure data sharing
with Office Open XML (OOXML) package extended by a sticky
policy in eXtensible Access Control Mark-up Language
(XACML) format. Research used Identity Based Encryption
(IBE) primitive to securely bind the policy and the data together.
High availability required from cloud service is here achieved
using distributed system components. The Git repository and the
Blockchain, leveraged technologies are not new, however their
application for IRM system is novel and brings it closer to
universal approach and open architectural construct.
