Your question is not very clear, but I believe you would like to know how the EU GDPR regulation will affect publishers and authors. GDPR, or General Data Protection Regulation, is a new regulation by the EU that has come into effect from May 25, 2018. It entails tighter protection of personal information of all EU residents and stricter data privacy regulation.
For publishers, it means tighter control of the data that they collect ensuring that appropriate consent is obtained and the data is properly protected. This also applies to authors outside the EU. If your content contains any identifying information about EU residents then consent need to be obtained. EU residents will have the authority to withdraw their consent anytime and the content must be used for explicit legitimate purposes only.
It is unclear how this will impact, if at all, the publishing costs for authors from the EU or other nations. If there are any changes, these should be reflected on the journal website.
