US Patent 9807061 Privacy server for protecting personally identifiable information

A privacy server protects private information by substituting a token or an identifier for the private information. The privacy server recognizes that a communication includes private information and intercepts the communication. The privacy server replaces the private information with a random or pseudo-random token or identifier. The privacy server maintains the private information in a local database and associates the private information for a particular person with the token or identifier for that person.
