<p>Nowadays, content proliferation makes protecting intellectual property vital. Digital watermarking has emerged as a key tool in the protection of digital content, striking a balance between safeguarding content and allowing its distribution without hindrances. Of all types of content, text is the hardest to watermark because of the low embeddability of the medium. This article presents one new structural watermarking technique and various combinations of it with others we previously proposed as a way to improve embeddability and to offer greater robustness to attacks. The efficacy of these new techniques has been validated against a novel suite of attacks designed to emulate the operational methodologies a human attacker might utilize to compromise protected content. We consequently propose this attack suite as a new, standardized benchmark for the rigorous assessment of future techniques. Robustness is evaluated across different payload sizes at varying attack magnitudes, starting from 10% of the text’s length, a scale recognized in literature as a substantial attack. All techniques show promising results. In particular, combining all three watermarking techniques, we achieve near perfect results against the attacks considered, for all payload lengths. Lastly, we compare our full suite technique to four other structural watermarking techniques already present in the literature, with results that confirm that our proposed method is as robust as others or performs better, especially against <i>copy &amp; paste</i> attacks.</p>
