15. A system comprising:
one or more electronic devices configured to implement a storage service to store a file; and
one or more electronic devices configured to implement a content delivery service, the content delivery service including instructions that upon execution cause the content delivery service to perform a method comprising:
receiving a request at the content delivery service from a user for the file,
generating a piracy risk score with greater than two possible values for the file by a fuzzy logic expert service of the content delivery service,
inserting a covert watermark into the file and sending the file with the covert watermark to the user based on the piracy risk score with greater than two possible values not exceeding a threshold,
performing a remedial action for the file, requested by the user, based on the piracy risk score with greater than two possible values exceeding the threshold,
scanning for the covert watermark in a data store external from the content delivery service and external from the user to detect a possible pirated version of the file, and
triggering generation of a fuzzy logic rule of the fuzzy logic expert service based on detection of the covert watermark in the data store external from the content delivery service and external from the user.
