Secure and private network communications

A non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors of a network communication system comprising a client device, a pre-proxy server, a forward proxy server, a destination server, and a nameserver, cause the system to:

• transmit, from the client device to the nameserver, a request for a network address of the destination server;
• transmit, from the nameserver to the client device, in response to the request for the network address of the destination server, a network address of the pre-proxy server, wherein the network address of the pre-proxy server is different from the network address of the destination server, such that use of a multi-party relay communication pathway is enforced by causing traffic for the destination server that uses the nameserver to be automatically redirected through the multi-party relay communication pathway;
• transmit, from the client device to the pre-proxy server, based on the network address of the pre-proxy server, a transmission comprising a request to access a service hosted at the destination server, wherein the transmission comprises data intended for the destination server and identity information identifying the client device;
• transmit, from the pre-proxy server to the forward proxy server, in response to receiving the transmission from the client device, a first transmission comprising the data intended for the destination server and instructions for forwarding the data to the destination server, and wherein the first transmission does not include the identity information identifying the client device;
• and
• transmit, from the forward proxy server to the destination server, in response to receiving the first transmission from the pre-proxy server, a second transmission comprising the data intended for the destination server.

A method, performed by one or more processors of a network communication system comprising a client device, a pre-proxy server, a forward proxy server, a destination server, and a nameserver, the method comprising:

• transmitting, from the client device to the nameserver, a request for a network address of the destination server;
• transmitting, from the nameserver to the client device, in response to the request for the network address of the destination server, a network address of the pre-proxy server, wherein the network address of the pre-proxy server is different from the network address of the destination server, such that use of a multi-party relay communication pathway is enforced by causing traffic for the destination server that uses the nameserver to be automatically redirected through the multi-party relay communication pathway;
• transmitting, from the client device to the pre-proxy server, based on the network address of the pre-proxy server, a transmission comprising a request to access a service hosted at the destination server, wherein the transmission comprises data intended for the destination server and identity information identifying the client device;
• transmitting, from the pre-proxy server to the forward proxy server, in response to receiving the transmission from the client device, a first transmission comprising the data intended for the destination server and instructions for forwarding the data to the destination server, and wherein the first transmission does not include the identity information identifying the client device;
• and
• transmitting, from the forward proxy server to the destination server, in response to receiving the first transmission from the pre-proxy server, a second transmission comprising the data intended for the destination server.
