A data processing system to restrict content transmission in a networked environment, comprising: an interface configured to receive a content request from a client computing device; a natural language processor configured to: receive an input audio signal comprising the content request; parse the input audio signal to identify the content request and a trigger keyword; a content selector component which, when executed by the data processing system, is configured to select a first digital component based on the content request and the trigger keyword, the first digital component comprising a first plurality of characters; and a manipulation detection component which, when executed by the data processing system, is configured to: retrieve a dictionary comprising a plurality of candidate characters included in a plurality of digital components and a value or binary array for each candidate character listed in the dictionary; convert the first plurality of characters into an array of values or an array of binary arrays using the dictionary; classify the first digital component into a non-manipulated class or into a manipulated class based on a sequence of the first plurality of characters in the array of values or the array of binary arrays; based on a classification of the first digital component into the non-manipulated class, determine to include the first digital component in a response to the content request from the client computing device; based on a classification of the first digital component into the manipulated class, determine not to include the first digital component in the response to the content request from the client computing device; and generate the response based on the content request from the client computing device, wherein the response includes the first digital component when the first digital component is classified into the non-manipulated class and the response does not include the first digital component when the first digital component is classified into the manipulated class. an interface configured to receive a content request from a client computing device;
