Abstract

WHOIS service allows people to ask the current registrant some Internet resources. WHOIS service has become an indispensable information service in the DNS. Unfortunately, WHOIS information is often available by the malicious third party. In this paper, we first analyzed the whole process of the WHOIS protocol. And then the process of the WHOIS privacy collection is analyzed through the clustering method. Several methods of protection of the WHOIS privacy are proposed in this paper. Through the experimental results it can be seen that the protection method can better protect the privacy of WHOIS information in DNS.
