Then， it elaborates the characteristics and needs of different types of privacy in terms of identity privacy， location privacy and data privacy as well as the key privacy protection technologies and methodological evolutions for different privacy types . On this basis， the representative privacy metrics schemes， theoretical models， and metrics challenges for different types of privacy are studied in depth across multiple privacy domains.
