Because the article was not published, the other party published it online privately, which violated your right to publish. Secondly, if the other party doesn't sign the article, or signs someone else's name, it infringes on your right of signature. In addition, if the other party gets corresponding benefits from this, it infringes on your property rights in other works.

In a word, the behavior of the actor has constituted an infringement of your copyright, and you have the right to ask him to stop the infringement. However, the right of publication is a one-time right, once exercised, it will cease to exist, so it cannot be restored to its original state. You can ask the actor for compensation.

If you suffer losses, you have the right to ask him to compensate for the corresponding losses. If the loss is not easy to calculate and the other party benefits from it, he may be required to return the benefits. If it is difficult to calculate, then the copyright law stipulates that you can claim compensation for less than 500 thousand yuan, and you can make a request according to the specific situation. Of course, because the right to publish by signature belongs to the personal right of the work, the actor can also be required to bear the responsibility of spiritual comfort such as apology.

For reference only, I hope I can help you. If you have any questions, you can ask them. Please correct me if there is anything wrong.
