Composers, songwriters, poets, writers, painters, graphic designers, project owners, software engineers and artefact creators can be the subject of many conflicts once they complete their works. With this platform, a certificate service, which has legal validity and can be used in disputes in order to protect the rights of the owners, is provided. A timestamp is a certificate with legal value, which allows you to attribute a specific date and time to an electronic document. Since the timestamp is of evidence, it provides legal protection against a possible plagiarism.
