Techniques are disclosed for helping users of virtual worlds and social networking applications to control personal identity data that other users have access to and to determine the type of identity data that users know about each other. Generally, identity awareness records may be used to store the personal identity data that a user has revealed to other users. When the user sends information to another user, personal identity data is mapped to appropriate aliases, depending upon which user is receiving the information. When the user is in the presence of other users, a visual dashboard indicates the types of personal identity information that the user knows about each other user, as well as the types of personal identity information that each other user knows about the user. The visual dashboard may also indicate the types of personal identity information that the other users know about each other.
