User authenticated encrypted communication link

A domain name server configured to register a client for secure communications, the domain name server comprising:

• a data storage device;
• and
• one or more processors configured to:
• (1) receive, from the client, a user name associated with a user of the client;
• (2) generate, based on receipt of the user name, a random hash key;
• (3) transmit, to the client, the random hash key;
• (4) receive, from the client, a hash value generated by hashing, using the random hash key, a biometric identification vector including biometric information of the user;
• and
• (5) register, in a database stored in the data storage device, the user name in association with the received hash value to authenticate domain name service requests from the client.

A method performed by a client for registering with domain name server for secure communications, the method comprising:

• sending, to the domain name server, a user name associated with a user of the client;
• receiving, from the domain name server, a random hash key, wherein the random hash key is generated based at least in part on the user name;
• receiving biometric information of the user;
• generating a biometric identification vector based on the biometric information;
• generating a hash value by hashing the biometric identification vector using the random hash key;
• and
• sending the hash value to the domain name server.

A client device configured to register with domain name server for secure communications, the client device comprising:

• a data storage device storing (1) a user name associated with a user of the client device and (2)
• a biometric identification vector generated based on biometric information of the user;
• and
• one or more processors configured to:
• send the user name to the domain name server;
• receive, from the domain name server, a random hash key, wherein the random hash key is generated based at least in part on the user name;
• generate a hash value by hashing the biometric identification vector using the random hash key;
• and
• send the hash value to the domain name server.
