How do you prove you created something first?

The most reliable method is a qualified electronic timestamp from a QTSP listed on the EU Trusted List. Under eIDAS Art. 41(2), a qualified timestamp carries a legal presumption of accurate time and data integrity. It is generated by an independent trusted authority and cannot be altered without invalidating the timestamp. Self-generated evidence such as file metadata, email timestamps, and social media posts does not carry this presumption.

Is a file timestamp enough to prove creation date?

No. File system timestamps can be changed by anyone with filesystem access. Courts treat file metadata as unreliable standalone evidence of creation date. An email to yourself or a social media post creates a platform timestamp, but these are secondary evidence. A qualified electronic timestamp from an accredited QTSP is the legally reliable standard.

What is a qualified electronic timestamp?

A qualified electronic timestamp is a trust service from a QTSP listed on the EU Trusted List. Under eIDAS Art. 41(2), it carries a legal presumption that the date and time indicated are accurate and that the data has not been altered. The timestamp is generated using a trusted time source (RFC 3161) and cryptographically bound to a hash of the document. Swiss Trust Layer applies a qualified timestamp at sealing, starting.

Does copyright registration prove creation date?

Switzerland and most EU countries do not have copyright registration systems, as copyright arises automatically under the Berne Convention. Where registration exists (such as in the US), a registration certificate provides evidence of the registration date, not necessarily the creation date. A qualified electronic timestamp is a more direct method of proving creation date.

What level of evidence do courts require for creation date?

In Swiss and EU civil proceedings, courts require independent evidence from a source that cannot have been manipulated by the claimant. A qualified electronic timestamp from an EUTL-listed QTSP satisfies this requirement: the QTSP is an accredited authority, and the timestamp is cryptographically bound to the document content, making retroactive alteration detectable.

In short

版权在创作时即自动产生。但当争议发生时，举证责任在您。这些方法在瑞士和欧盟法律下能经受法底检验，而另一些方法则不能。

根据《伯尔尼公约》，版权在创作时自动产生。但在纠纷中，举证创作日期的责任由创作者承担。文件系统元数据、发送给自己的电子邮件和社交媒体帖子不是可靠的证据。依据eIDAS第41(2)条，合格电子时间戳具有日期准确性和数据完整性的法定推定。由EUTL上的QTSP按RFC 3161生成。Swiss Trust Layer。验证：validate.swisstrustlayer.com。

云存储不是保管：瑞士身份核验托管存储究竟改变了什么

Dropbox、谷歌云端硬盘、公司共享文件夹：它们都把访问权交给持有登录信息的人，而不是文件真正的所有者。身份核验托管存储的运作方式不同，恢复权与经 KYC 核验的本人绑定，文件保存在瑞士，独立于任何云服务提供商。

AI版权诉讼实际进展到哪一步了,又有哪些问题是它们谁都没替你回答

四起案件常被笼统地称为"AI版权诉讼"。它们并非同一起案件,而且没有一起就未经许可用你的作品训练模型是否构成侵权作出过裁决。以下是安德森案、纽约时报诉OpenAI案、盖蒂诉Stability案和巴茨诉Anthropic案的真实进展,以及无论这些案件如何或何时收场,创作者自己能够证明什么。

工程师走出门口之前的那一刻,才是真正重要的时刻

知识产权风险不是从辞职信开始的,它集中在此前的几周内:没人标记为公司记录的私人代码仓库、个人邮件和未合并的分支。把源代码、设计文档和原型作为日常工作而非只在发布时封存,才能让初创公司的所有权在任何人离职时都经得起证明。

OpenAI、Google 和 Nvidia 都支持内容凭证。这依然不等于法庭上的证据

内容凭证如今来自 ChatGPT 生成的图片、专业相机,很快还会来自 Chrome 本身。这让来源信息可以大规模被读取。但它并不能让一份清单变成法院推定其日期准确的东西。
