Abstract: A method for anonymization of personal data is provided for protecting the privacy of a user while sharing user information with a third party. The method includes receiving from a user a domain name address associated with an intended website and an Internet Protocol (IP) address associated with the user and determining that the domain name address is an invalid domain name. The method may further include encrypting the IP address associated with the user by translating the IP address into a unique identifier, with the encryption being a one-way hashing process, and then sending the unique identifier and the invalid domain name address to the third party.
