Abstract
A system and method for transmitting protected real-time content from one user to another is described. In a first aspect, a user sends a Rights Object to another user. In a second aspect, a user sends a Rights Object to another user via an intermediate server for a multiparty communication. In this second aspect, the users may be able to switch between designated Rights Objects as needed.

A method comprising:
- at a first device, receiving a plurality of rights objects, each rights object of the plurality of rights objects is associated with a user of a plurality of users, wherein:
- the plurality of users includes a first user and a second user, and
- the plurality of rights objects includes a first rights object associated with the first user and a second rights object associated with the second user;
- receiving first protected content and a notification identifying an associated user;
- determining which user of the plurality of users is the associated user;
- in response to determining that the first user is the associated user, decrypting the first protected content based on the first rights object;

An apparatus comprising:
- at least one processor;
- and
- at least one memory storing computer executable instructions that, with the at least one processor, cause the apparatus to:
- receive a plurality of rights objects, each rights object of the plurality of rights objects is associated with a user of a plurality of users, wherein:
- the plurality of users includes a first user and a second user, and
- the plurality of rights objects includes a first rights object associated with the first user and a second rights object associated with the second user;
- receiving first protected content and a notification identifying an associated user;

One or more computer readable media storing computer executable instructions that, when executed, cause a processor to:
- receive a plurality of rights objects, each rights object of the plurality of rights objects is associated with a user of a plurality of users, wherein:
- the plurality of users includes a first user and a second user, and
- the plurality of rights objects includes a first rights object associated with the first user and a second rights object associated with the second user;
- receiving first protected content and a notification identifying an associated user;
- determining which user of the plurality of users is the associated user;
- in response to determining that the first user is the associated user, decrypting the first protected content based on the first rights object;
- and
- in response to determining that the second user is the associated user, decrypting the first protected content based on the second rights object.
