Abstract
A method implemented in a computing system hosting a three-dimensional virtual reality world. The computer system stores a set of searchable records, each having: a searchable hash of at least a portion of personally identifiable information; and an encrypted identity, decryptable using an encryption key generated based at least in part on the searchable hash and a global key. In response to a search request identifying at least a portion of personally identifiable information as a search criterion, the computer system generates a hash of the search criterion, and finds a matching searchable record that has a searchable hash equal to the hash computed from the search criterion. An encryption key is computed based on the global key and the matched searchable record to decrypt an encrypted identity of a user having at least the portion of personally identifiable information that is the search criterion in the search request.
