E/C.12/GC/17 page 8 take measures that prevent third parties from interfering with the moral and material interests of authors. Finally, the obligation to fulfil requires States parties to adopt appropriate legislative, administrative, budgetary, judicial, promotional and other measures towards the full realization of article 15, paragraph 1 (c).21 29. The full realization of article 15, paragraph 1 (c), requires measures necessary for the conservation, development and diffusion of science and culture. This follows from article 15, paragraph 2, of the Covenant, which defines obligations that apply to each aspect of the rights recognized in article 15, paragraph 1, including the right of authors to benefit from the protection of their moral and material interests. Specific legal obligations 30. States parties are under an obligation to respect the human right to benefit from the protection of the moral and material interests of authors by, inter alia, abstaining from infringing the right of authors to be recognized as the creators of their scientific, literary or artistic productions and to object to any distortion, mutilation or other modification of, or other derogatory action in relation to, their productions that would be prejudicial to their honour or reputation. States parties must abstain from unjustifiably interfering with the material interests of authors, which are necessary to enable those authors to enjoy an adequate standard of living. 31. Obligations to protect include the duty of States parties to ensure the effective protection of the moral and material interests of authors against infringement by third parties. In particular, States parties must prevent third parties from infringing the right of authors to claim authorship of their scientific, literary or artistic productions, and from distorting, mutilating or otherwise modifying, or taking any derogatory action in relation to such productions in a manner that would be prejudicial to the author’s honour or reputation. Similarly, States parties are obliged to prevent third parties from infringing the material interests of authors resulting from their productions. To that effect, States parties must prevent the unauthorized use of scientific, literary and artistic productions that are easily accessible or reproducible through modern communication and reproduction technologies, e.g. by establishing systems of collective administration of authors’ rights or by adopting legislation requiring users to inform authors of any use made of their productions and to remunerate them adequately. States parties must ensure that third parties adequately compensate authors for any unreasonable prejudice suffered as a consequence of the unauthorized use of their productions. 32. With regard to the right to benefit from the protection of the moral and material interests resulting from any scientific, literary or artistic production of indigenous peoples, States parties should adopt measures to ensure the effective protection of the interests of indigenous peoples relating to their productions, which are often expressions of their cultural heritage and traditional knowledge. In adopting measures to protect scientific, literary and artistic productions of indigenous peoples, States parties should take into account their preferences. Such protection might include the adoption of measures to recognize, register and protect the individual or collective authorship of indigenous peoples under national intellectual property rights regimes and should prevent the unauthorized use of scientific, literary and artistic productions of indigenous peoples by third parties. In implementing these protection measures, States parties should respect the principle of free, prior and informed consent of the indigenous authors
