Information spreading is a important topic in the area of Online Social Networks (OSNs). Typically, information flows in a careless way among directly connected members of the OSN ("friends"). In this way, it is possible that sensitive information is unintentionally leaked to not entitled or un-trusted members. A well-known approach for the management of trust relationships is represented by trust negotiations. In an OSN, trust negotiations can be exploited in a novel way, that is, their outcome can be used to dynamically adjust the trust level between OSN users. Additionally, information about past negotiations between members of the OSN can be propagated in the OSN graph and used by other OSN members to take access control decisions. However, such information can be sensitive and therefore their disclosure should be carefully regulated. To cope with these issues, in this paper we introduce a language for the definition of policies regulating the disclosure of information about past interactions occurred between members of the OSN.
