Abstract (en)

[origin: WO9810558A1] A system for establishing anonymous communications includes a plurality of party terminals (300), a plurality of requestor terminals (400), and a central controller (200). The system receives and stores party data about respective parties. Upon receiving criteria for parties of interest from a requestor terminal (400) and authorization from respective parties, the central controller (200) releases to the requestor party associated with the parties. The system also establishes communication channels between parties and the requestor, while maintaining their anonymity. Communications are through the public switched telephone network (110).
