The researchers calculate how much shared information exists between a person's input (a prompt, an edit, a sketch) and the AI-assisted output, then compare that against the output's total self-information. The ratio gives a numeric score for the human's proportional contribution rather than a yes-or-no judgment. In tests across several creative domains, the researchers say the measure reliably told apart works with heavy human involvement from ones that were mostly AI-generated with light prompting.\n\nThis matters because originality has become a genuinely hard problem to define. Copyright offices and courts have spent the last few years trying to figure out how much human input is enough to make an AI-assisted work protectable, and right now that judgment is mostly a case-by-case guess. A quantitative score would not settle the legal question, but it would give publishers, platforms, and regulators a consistent way to talk about degrees of human authorship instead of arguing in the abstract.\n\nStill, a formula is not a law. Turning a mutual-information score into an actual originality threshold - and getting courts, platforms, or copyright offices to agree on where that line sits - is a much messier fight than the math behind it.","[\"ai\",\"generative-ai\",\"copyright\",\"research\"]","2026-09-16T04:00:00.000Z","2026-09-17T16:57:33.028Z","2026-09-17T16:57:44.930Z","published",null,[],"ai",[24,26,27,28],"generative-ai","copyright","research",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2408.14792",0,{"sections":35},[36,40,45,50,55,59,63,68,73,77,82,87,92,97],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",3853,"2026-09-17T08:27:09.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":44},"Security","security",648,"2026-09-17T04:00:00.000Z",{"name":46,"slug":47,"count":48,"latest_published_at":49},"Policy","policy",338,"2026-09-11T04:00:00.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":44},"Hardware","hardware",154,{"name":60,"slug":61,"count":62,"latest_published_at":44},"Science","science",114,{"name":64,"slug":65,"count":66,"latest_published_at":67},"Consumer Tech","consumer-tech",99,"2026-09-09T17:27:33.000Z",{"name":69,"slug":70,"count":71,"latest_published_at":72},"Software","software",75,"2026-09-10T20:41:21.000Z",{"name":74,"slug":75,"count":76,"latest_published_at":44},"Dev Tools","dev-tools",73,{"name":78,"slug":79,"count":80,"latest_published_at":81},"Startups","startups",55,"2026-09-09T23:14:29.000Z",{"name":83,"slug":84,"count":85,"latest_published_at":86},"Gaming","gaming",43,"2026-09-10T12:18:06.000Z",{"name":88,"slug":89,"count":90,"latest_published_at":91},"General","general",41,"2026-09-08T01:57:23.000Z",{"name":93,"slug":94,"count":95,"latest_published_at":96},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":98,"slug":99,"count":100,"latest_published_at":101},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
