Creative Commons is a standardized method to indicate to what extent you accept that your work gets used, shared, and copied.
If you have created a work yourself (typically in an electronic format) – e.g. a text, picture, a PowerPoint presentation, a video etc. and want to share it with others to some extent without them having to ask permission first, then a Creative Commons license could be a solution.
The copyright for your publications is, as a general rule, connected to you as a researcher - unless there are other arrangements between you and your workplace/institution. When publishing you need to be aware of whether you write off your copyright to the publisher as this has significance for your right to parallel-publishing, e.g. in relation to a PhD publication, or a publication via PURE, or the publication list on your research profile, or using your work in your teaching etc.
If you are using pictures or illustrations in your publications/books that are not your own, then you have to make sure that you have permission from the originator of the works. If not, then it is illegal, and you are at risk of your article or PhD being refused publication. If you have obtained the rights for usage, then you need to remember to credit the person.
The Committee for Protection of Scientific Work (UBVA) has created Forskerportalen.dk (the Researcher Portal) which provides information on legal and ethical issues in relation to research. On this site you can get information on, for example, your rights in relation to research, publishing, academic freedom, responsible conduct of research etc.
Remember that the responsibility for complying with the applicable rules on copyright rests with the user of a given material. The information in this guide is provided as inspiration and are neither constituted of or a substitute for personal legal advice.
