Abstract: Methods for simultaneous exchange of sensitive personal information between two unrelated parties are disclosed, such as between two users of an online networking website or introductory meeting website, the information being mutually accessible to both users upon exchange. The invention allows for exchange of sensitive personal information between two parties only if both parties indicate a willingness to participate in such exchange. A host data server facilitates information exchanges, otherwise protecting the sensitive personal information. This invention is particularly useful for online dating websites, where the sensitive personal information may include personal photographs or phone numbers. In preferred embodiments, the exchange of sensitive personal information occurs simultaneously, and the sensitive personal information can be simultaneously presented to the two parties.
