Watermarking of structured results and watermark generation

A method, comprising:

• computing a hash of at least part of each of a plurality of alternative structured results to produce a bit sequence corresponding to each alternative structured result;
• computing a ranking score for each alternative structured result based upon a distribution of binary digits in its corresponding bit sequence;
• and
• selecting one of the plurality of alternative structured results based upon the ranking score to obtain a watermarked structured result, the watermarked structured result having been determined to include machine-generated content that is not appropriate for machine learning by a language translation model.

A system, comprising:

• a database storing a plurality of alternative structured results;
• a processor in connection with the database, the processor configured to:
• compute a hash of at least part of each alternative structured result to produce a bit sequence corresponding to each alternative structured result;
• compute a ranking score for each alternative structured result based upon a distribution of binary digits in its corresponding bit sequence;
• and
• select one of the plurality of alternative structured results based upon the ranking score to obtain a watermarked structured result, the watermarked structured result having been determined to include machine-generated content that is not appropriate for machine learning by a language translation model.
