Systems and methods for authenticated control of content delivery

A method for authenticated control of content delivery, comprising:

• receiving, by a server device, a request for an item of content from a computing device, the request comprising a security token associated with the computing device and an identifier of a group of domains with which the security token is associated;
• identifying, by the server device, the group of domains from the identifier;
• retrieving, by the server device, a security key associated with the group of domains;
• decrypting, by the server device, a signature of the security token using the security key;
• identifying, by the server device, an authentication string associated with the security token;
• determining, by the server device, that the authentication string matches a server authentication string;
• responsive to the determination that the authentication string matches the server authentication string, retrieving, from the request and by the server device, a second security key included in the request;
• responsive to the determining that the authentication string matches the server authentication string and that a second authentication string associated with the security token matches a second server authentication string,
• identifying, by the server device, characteristics of the security token, wherein the characteristics of the security token comprise a confidence score indicating a likelihood that the computing device is not associated with a malicious entity;
• comparing, by the server device, the confidence score of the security token to a threshold;
• determining, by the server device, that the confidence score does not exceed the threshold;
• and
• responsive to the determination that the confidence score does not exceed the threshold, preventing, by the server device, transmission of content to the computing device.
