Signed authors refer to works (such as articles, research reports, works of art, etc.). ) marked with the author's name or signature. This is a crucial intellectual property protection measure, which can not only let readers or viewers know who the creator is, but also let the author enjoy the copyright of the work. In academic or publishing circles, the signed author refers to the main author who has participated in the creation and is responsible for the work.

The concept of signed author is closely related to the origin of modern copyright law, and its history can be traced back to Europe in the18th century. At that time, many authors began to sign their works in order to avoid piracy. With the gradual improvement of a series of laws such as patent law and copyright law, signed authors have become an important part of modern copyright protection.

The concept of signed author is not only of great significance in copyright protection, but also involves the determination of the value of the work and the social status of the creator. For some famous writers, painters and musicians, their signature works are not only economic wealth, but also cultural heritage. Therefore, when publicly displaying or trading artworks, the identity of the signed author has also become an important factor for buyers and investors to consider.
