1. In fact, most SCI journals do not require authors to provide original data, because this will involve the author's copyright and other related matters. Many authors are reluctant to disclose the original data of their articles in order to protect their articles, so in general, authors do not need to submit the original data.
2. If peer-reviewed editors or external audit experts have doubts or doubts about the data in the article and explicitly ask the author to provide the original data of the article, then the author should not only provide the original data, but also provide detailed information such as the data processing process and the serial number of the processing software used.
In short, as far as SCI papers are concerned, if the author submits the original data, most of them are uploaded through the submission system, so there will be no data leakage or plagiarism, and formal publications will strictly keep the original data submitted by the author confidential and safe.
