Blocking Reshare for a Business Partner

You can block reshare for a business partner that you do not want to share your objects with.

Context

You can use the blocking feature in the network to:

Maintain a list of blocked organizations in the network. You can add any other premiums and their invitees (premiums and invitees must be belonging to same virtual network) to this blocking list.

Note

You cannot block your own invitees and invitees cannot block their own premiums. When an invitee becomes a premium, you have to add this newly converted premium to the block list in case you want to block their share feature.
Blocked organizations will not receive any of your data when other business partners reshare your data.
You can directly share your data to the organizations in your block list. In this case, blocked organizations will receieve your data.
Blocking feature is enabled for premiums, freemiums, and invitees, that is, an invitee organization or a freemium or a premium organization can maintain the block list.

A, B, C, D are premiums in the network and have maintained the following block list:

A cannot receive objects owned by B that is shared by business partners other than B.
B is not blocked.
C cannot receive objects owned by A that is shared by business partners other than A and C cannot receive objects owned by B that is shared by business partners other than B.
D cannot receive objects owned by A that is shared by business partners other than A and D cannot receive objects owned by C that is shared by business partners other than C.
E is not blocked.

The blocking feature works as follows for the authorization groups created by these business partners:

Authorization Group	Owner of the Group	Business Partners in the Group	Block Feature
CA	A	B, C, D	The owner A can not only add his own objects to the authorization group, but also objects shared by B and C. Since A is directly sharing objects, C can access objects owned by A. But C cannot access the objects owned by B, and D cannot access the objects owned by C as that is reshared by A in this group.
CB	B	A, C	The owner B can add objects owned by him to circle CB and he can also add objects shared by A to this authorization group. But C cannot access the objects owned by A as that is reshared by B in this group.
CC	C	A, B, D	The owner C can add objects owned by him to the authorization group CC and he can also add objects shared by B to this group. But A cannot access the objects owned by B as that is reshared by C in this group.
CD	D	E	The owner D can add his objects and other dependent objects (owned by A, B, C, D,E) to this authorization group and E gets access to all these objects as E is not blocked by anyone.
