Data processing systems and methods for automatically blocking the use of tracking tools

A system comprising:

• a server comprising
• a non-transitory computer-readable medium storing instructions;
• and
• a processing device communicatively coupled to the non-transitory computer-readable medium,
• wherein, the processing device is configured to execute the instructions and thereby perform operations comprising:
• receiving a Hypertext Transfer Protocol (HTTP) request to render a webpage;
• and
• responsive to receiving the HTTP request, sending a HTTP response comprising a script to a computing device associated with a user;
• and
• the computing device, wherein the computing device is configured to execute, within a browser and during a loading of the webpage prior to execution of a source script, the script to perform additional operations comprising:
• identifying the source script attempting to execute;
• identifying the source script is configured to invoke a tracking tool based on information on the tracking tool found in a data set embedded in the script;
• identifying a category associated with the tracking tool based on the information on the tracking tool found in the data set;
• determining that the category has not been authorized by the user;
• and
• responsive to determining that the category has not been authorized by the user, blocking the source script from executing to invoke the tracking tool.

A non-transitory computer-readable medium having program code that is stored thereon, the program code executable by one or more processing devices for performing operations comprising:

• loading a webpage;
• during the loading of the webpage:
• identifying a tracking tool associated with the webpage;
• identifying a source script executed, wherein the source script invokes the tracking tool during the loading of the webpage;
• determining a category for the tracking tool by comparing data associated with at least one of the tracking tool or the source script to known tracking tool data;
• generating a data set, wherein the data set associates the source script with the tracking tool and the category;
• generating program code, wherein the program code is configured to, during the loading of the webpage to be viewed by a user and prior to execution of the source script:
• detect that the source script is attempting to execute,
• identify, based on the source script, the category from the data set;
• determine that the category has not been authorized by the user;
• and
• responsive to determining that the category has not been authorized by the user, block the source script from executing to invoke the tracking tool.
