METHOD OF ANONYMIZATION

The method involves encrypting profile data collected by a terminal of a user key with a shared confidentiality between the terminal and a data collection server (24). The profile data and the encrypted data are transmitted to identify the user identification with an anonymization server interposed between the terminal and the collection server, where the anonymization server encrypts the data to work toward the identification of the user with an anonymization key of the anonymization server before relaying the encrypted collected data and the anonymized data to the collection server. An independent claim is also included for a system for anonmyzing data to work toward identification of a user during collection of a profile by a targeting data collection server.
