Abstract
Systems and methods are described for the generation of domain names that may be associated with a particular user device and may be encrypted to obfuscate the domain names of content requested by the user device.
Claims20
A method comprising:
- sending, to a first user device, an encrypted domain name;
- receiving, from the first user device, a content request comprising the encrypted domain name;
- decrypting the encrypted domain name;
- determining, based at least on a domain name system resolution of the decrypted domain name, a network address associated with the decrypted domain name;
- and
- sending, to the first user device, the network address of the content.

A method comprising:
- sending, by a user device, a request for content;
- receiving an encrypted domain name;
- sending a first request to resolve the encrypted domain name;
- receiving a network address of the content;
- sending a second request for the content using the network address;
- and
- receiving the requested content.
4 more elements
A method comprising:
- receiving, from a user device, a request for content;
- retrieving the content comprising one or more domain names;
- encrypting a first domain name of the one or more domain names with a corresponding encryption key;
- replacing the first domain name with the corresponding encrypted domain name to form modified content;
- and
- sending, to the user device, the modified content comprising the encrypted domain name.
