A system and method for enabling users to more efficiently manage and control user demographic data in an information network, such as the Internet, including provision of infomediary services. The system may comprise a network, wherein a plurality of providers, such as information providers and service providers, may be coupled to the network. One or more databases may also be coupled to the network which include demographic information of various users. Users may operate computing devices to access the network for information and services. The demographic information stored in databases on the network is not usable or accessible by third parties for providing information to the various users. Each of the computing devices operated by various users may include a digital certificate which may store access information for enabling use of the respective user's demographic information. Thus, a user may use the stored digital certificate to manage access to the user's demographic data stored in the database. A user may selectively provide a digital certificate to the database, or a provider, to selectively allow access to the respective user's demographic data. |
