Abstract
Systems and methods are provided for determining a presence of a watermark in electronic data. In certain embodiments, a plurality of keys is generated, and a plurality of payloads are retrieved from electronic data using the keys. A statistical indicia of randomness is generated based on the payloads, and the presence of a watermark is determined when the indicia is below a threshold.
