Abstract: Techniques described herein relate to facilitating interaction in the physical world, after initial interaction has occurred within the virtual world, while also maintaining at least a degree of privacy, anonymity, safety, and/or deniability for the physical world parties. This may be accomplished, according to some example embodiments, by the exchange of one or more self-identifiers between virtual world personas, each of which is defined by its sending physical world party but that lacks any personal identification information associated with the sending party. Content of a self-identifier may only be known to the sending physical world party, at least until the receiving party is authorized and/or consents to view or display the self-identifier in a manner that may be perceived by the sending party. A sending party that perceives their own self-identifier, as displayed by a receiving party, may correlate the receiving party with a virtual world persona to which the self-identifier was sent.
