A new European Union regulation meant to make AI content identifiable might have surveillance-like consequences for marketers.<\/p>\n
Regulation (EU) 2024\/1689 of the European Parliament (informally the \u201cE.U. AI Act<\/a>\u201c) promises transparency, but by requiring \u201csynthetic\u201d content to be machine-detectable, it also creates infrastructure that could let governments or platforms segregate and censor text based on how it was produced rather than its quality.<\/p>\n In response to the rule, Anthropic announced<\/a> that all future versions of its Claude models will add identifiable, text-based \u201cwatermarks.\u201d<\/p>\n Other AI companies are likely to follow.<\/p>\n A system for detecting AI-generated content could lead to its censorship.<\/p>\n<\/div>\n The E.U. wants to know when something is AI-generated<\/a>.<\/p>\n Some folks would swear an em dash (\u2014) or a colon (:) is a sure sign of AI-generated text, but both of these punctuation marks have been around and in use for much longer than ChatGPT, Claude, or similar.<\/p>\n A database of AI\u2019s writing affinities and proclivities would soon be outdated. AI writing is becoming more human-like every day by design.<\/p>\n Thus guessing what an AI wrote is sketchy at best. But that won\u2019t satisfy the E.U.<\/p>\n Anthropic will rely on a Google-developed, text-based watermarking approach called SynthID-Text<\/a>.<\/p>\n The approach embeds a hidden watermark while the AI model is generating text. The watermark is detectable without returning to the LLM, referencing a database, or using much computational power.<\/p>\n In the AI context, a token is bite-sized data such as parts of words, whole words, numbers, or punctuation marks.<\/p>\n When prompted to produce a blog post, a product description, or an email marketing message, the generative AI model starts with a token, then guesses the next one.<\/p>\n To explain, Google Gemini used a sentence that begins with \u201cmy favorite tropical fruit is.\u201d Gemini would then apply statistical probability to choose the next token, and it won\u2019t always choose the same one.<\/p>\n Those reasonable alternatives give SynthID the opportunity to run a tournament.<\/p>\n SynthID selects competitors akin to a sports tournament.<\/p>\n SynthID conducts a tournament for each new token created, building a statistical watermark with each winning token.

But after hundreds of these contests, watermarked text contains more seed-influenced tokens than ordinary chance should produce.<\/p>\n That statistical pattern is the watermark.<\/p>\n A \u201cdetector\u201d algorithm with the secret key can split a passage into its underlying tokens, reconstruct the tournament scores, and determine whether the various token choices correlate strongly enough with the watermark to cross a detection threshold.<\/p>\n Longer passages provide more evidence. One or two winning tokens could happen by chance. Hundreds provide much stronger evidence that SynthID influenced the choices.<\/p>\n Conversely, factual passages or lots of user feedback during the composition process produce relatively less evidence because the model has fewer acceptable choices.<\/p>\n Nonetheless, any passage of text scoring above the detection threshold would be considered AI-generated or, at least, AI-aided.<\/p>\n The ability to identify AI-generated text with relative ease and confidence means search engines, social networks, LLMs, or email clients could isolate the text and eventually filter or suppress it.<\/p>\n For ecommerce marketers, AI content segregation or censorship could undermine a key generative AI advantage, helping small teams create and repurpose content<\/a> inexpensively.<\/p>\n Watermarking could be a proxy for quality.<\/p>\nIdentification<\/h3>\n
