With concerns growing about students using ChatGPT to cheat on their homework, there’s been a lot of talk about how to spot AI-generated work. Although there are some tools designed to detect AI text, their reliability is often shaky. Recently, OpenAI has hinted at a solution: a new "text watermarking method." However, this method isn’t ready for widespread use just yet.
Watermarking And Metadata: How They Work
OpenAI has been developing two main methods to detect AI-generated text:
Watermarking: This technique involves adding a hidden text watermark to the AI-generated content. It’s proven to be quite effective, even against attempts to alter the text, like paraphrasing.
Metadata: Instead of using watermarks, OpenAI is also exploring the use of metadata. This method involves adding cryptographic signatures to the text, which makes it hard to tamper with or forge.
