The AI aspect of this is a red herring. The real problem is that they're secretly adding in a unique identifier into every image you create. If somebody does not like your meme, they can just send a copyright subpoena to Microsoft to instantly get your full name, address, email, phone number, and any other data associated with your Microsoft account. Just like age verification, this is another weapon in the war against internet anonymity.

> a unique identifier into every image you create

Printing anything is also a risk: It's very likely your printer is secretly adding marks to the page that contain its serial number and the current timestamp. [0] Meanwhile, Microsoft's "telemetry" is harvesting the serial numbers of all your devices, and correlating them to your MS account and/or current IP address.

This means your "anonymous" printout critiquing The Regime or showing Dear Leader in a clown costume can still lead thugs to your door, thanks to Microsoft. (And some printer-companies.)

Does it trigger on non AI images? The post doesn't say so at least.
Someone1234about 2 hours ago
It does kind of say: The GUID is coming from the moderation endpoint, which is hit when you generate a local or cloud AI image based on your prompt. If there is no prompt, there is no endpoint, and likely no GUID.

Obviously Paint could have been watermarking prior to AI though, but this specific AI watermarking appears to be only that.

The fact that local ai image generation uses an online moderation API is a bit worrying too....

I am a human and I upvoted the comment immediately. Do not underestimate the wide ranging hate for age verification. Even my normie friends are against it. Meta/etc have been buying those laws but at the cost of more and more people waking up to privacy activism. I predict in a couple years it'll backlash as people first fight against AV, and then fight for more broad privacy reform in the US. At least for myself, I had never been actively calling my reps until the AV laws.

a GUID isn't an indicator, it's a fingerprint.

so unless you want to draw a distinction between 'user' and 'machine' , yeah it is for identifying users.

A guid isn’t a user id, if it is in this case, it’s an abuse of how guid is used, at least colloquially. I haven’t read enough to understand if it is user / machine id, I.e. only globally unique in the sense it’s a globally unique entity identifier.

While it's definitely a dark pattern that I 100% do not agree with, Pro editions still allow you to do a local account. No need for the oobe /bypass command, still can be done through the OOBE GUI setup by selecting a Work/School account option then selecting Sign in options to then specify a local account to create.

Sorry for a dumb question but what would one use as a mailing address? Rent a PO box, or use a mail forwarding service, something like that?

qurrenabout 3 hours ago
Any of a number of virtual mailbox services which can receive mail for you, e.g. anytimemailbox.com but there are several. You can either pick up in person, or they offer services like mail forwarding, opening and scanning, etc.

Besides privacy against leaking your sleeping-address to businesses, they're also convenient for avoiding package theft if that's a problem in your area, and receiving/forwarding mail if you travel a lot for extended periods of time.

I'd recommend against PO boxes because (1) they get rejected by some services (2) UPS and FedEx won't deliver to them.

Because these businesses have to register as CMRAs and you have to sign a notarized form for them to legally receive mail for you, some services will still detect it and not let you use the address, but my experience for the most part has been that most US financial institutions let you enter a "residential/legal address" (no CMRAs allowed) and a "mailing address" (CMRAs allowed) separately, and the mailing address usually becomes your billing address.

As soon as you purchase something from Microsoft - e.g. your Office 365 subscription - they have at the very least your billing address on file for the credit card.

I'm posting this in the genuine interest of people being able to maintain anonymity from data leaks, privacy leaks, and in general not needing to tell businesses more personal information than is necessary to render services. This is in a country that has no protection of personal safety whatsoever, and any business data leak could mean life or death to average citizens who are being threatened by criminals, stalkers, and more.

AI-generated text warning (I submitted - but did not author - the piece), but it seems MS Paint and MS Photos add both a visible (can be turned off) and invisible (cannot be disabled and happens silently in the background with no user notice) watermarks to photos that have been AI-manipulated, even when using a local model to perform the action. It's not clear if this applies to even things like using AI-enhanced background delete/remove, but the invisible watermark is embedded in both the image pixels and the image metadata, both containing a GUID that can be linked to the exact prompt that was used and the originating device/user (on Microsoft's end).

Obvious next step is to explore if you can replace watermarker.dll with a (signed) no-op shim or MITM the API call to at least use your own (nil?) GUID that isn't linked to your device/account.

In case it's not obvious, my bigger concern isn't "this image can be identified to have been generated with/by AI" so much as it is "digital yellow printer dots have been forced upon us, except they can identify and retrieve the exact user/device/time/place/document/etc", completely destroying any and all illusions of privacy left.

Keep an eye on this.

A few months back, MS incorrectly tried to stamp a Copilot "watermark" (just an auto-added note) to any and all Azure DevOps commits, regardless of whether an LLM was actually involved. They removed it after a lot of github issues were submitted to the source of the issue which was a VS Code Copilot extension.

MS has been very sloppy in their implementations. I would recommend against using Paint or any other LLM enabled app they use as a result. Things may be getting incorrectly stamped.

Misleading title: the watermark applies to AI generated/edited images. That includes local models.

Whether it applies to non-AI generated images is a question for the reverse engineers (or ironically, a suitable AI). My bet is on "no".

Of course, the pre-AI versions of paint and notepad can still be installed with a bit of trickery, and it's worth it just for the UX.

Until proven otherwise via open-source audits and reproducible binaries, you should assume that all commercial photo editing software is embedding watermarks in any way they can get away with. This includes the professional software that you pay quite expensive licenses for. You should also assume that even if they're not today, they will eventually be coerced into doing so, in the same way that printers embed tracking dots.

It actually might make the new horrible world even worse. Imagine the populace getting used to a AI image detector flagging things as fake using this fairly easily defeated GUID marker system. Most people are just making memes or cat videos and don't even try to remove this so eventually the populace starts to believe these things actually work.

Now some one slightly more sophisticated starts creating deepfakes of a woman and uploading them or fabricating video of an political event without this marker. The subject protests it's fake and AI generated but a loud majority of ignorants feed it into Microsoft AI detector and call you a liar and say it's confirmed real. Most people don't know any better and eat it up because a computer said so.

This muddle of an article makes it totally unclear to me if this GUID is attached by the AI generation call or every image I edit in MS Paint. I'm going to assume the former unless they release a clarification.

Assuming the watermark works like the upcoming AI watermark for text, then it uses the content's entropy to embed the information. An all-black image doesn't have much entropy, so it's unlikely you'd find anything.

spicyjpegabout 3 hours ago
If C2PA and similar signature systems ever become a meaningful authenticity signal, they will create huge incentives for someone (potentially a state actor) to hack at least one camera in order to sign images of arbitrary provenance with its private keys. This will in turn inevitably lead to the same game of cat-and-mouse we have seen play out with video DRM schemes, where keys are regularly extracted from exploitable devices and used to decrypt as much content as possible before the device gets blacklisted entirely (harming all legitimate owners in the process).

hypferabout 3 hours ago
I don't think that that's a good idea, because it implies trust when there actually isn't any.

Being signed with something just means that whoever has that key could've done that. That might be the owner of a specific camera, but it might also be the camera manufacturer, anyone else in the supply chain, or anyone who dumped the key.

Imagine fake evidence signed with the same key as your camera uses being used in court against you. And the court believes it because it has this signature attached and those computers are very secure and all.

Exactly that will happen. Not widespread, of course, but it will.

sixothreeabout 3 hours ago
I was thinking any photo created with a camera should be signed. Why we don't have that in 2026 is beyond me.

But what you're talking about is the generative aspect of these photos likely expanding over time. We're seeing that today with the ultra zoom features on some cameras regenerating objects (and especially text). Without the user doing anything the phone will generatively fill in detail, most worryingly text and people. Then there's the Samsung moon issue - taking a photo of a pixelated printout of the moon caused Samsung phones to generate a new image of the moon.

Signing doesn't really achieve anything when an attacker can manipulate the device into signing arbitrary pixels.

How exactly would this work?

People take RAW photos. Load it up in a RAW editing tool. Manipulate it. Then load it in Gimp. Manipulate some more.

Will the final result have the signature?

And if it does, what use would it be?

Retr0idabout 1 hour ago
In the imaginary dream world that Adobe, Google et al live in, the final file does indeed have a signature.

Each piece of software in the chain must use TPM-like technologies (yes, even GIMP) to make sure it's running a "legitimate" build of the software, on "legitimate" hardware, and re-sign the file at each step along the way (using keys provisioned during some flavour of remote attestation flow, or using a RA-authenticated remote-signing oracle).

The final file embeds every preceding manifest, so you can "verify" all the way back to the original.

If this all sounds patently unworkable, that's because it is.

When I was in photography class in college, I created backplates in photoshop for still life portraits of small trinkets I was photographing. The photos were taken on black and white film and developed in the campus dark room. Led to some impressive photos. In our class's critiques, I explained how it was done. A lot of peers went from impressed to meh'd. The point: the black and white film laundered the new-age manipulation, and a digitally signed photo from a modern camera remains vulnerable to the same premise.

arjieabout 3 hours ago
Presumably the OP is proposing something like a TPM attached to the image sensor that signs the sensor output or something like that. You can’t sign it because you can’t get the key out. The key could be per-camera and be a published list.

I suppose a dedicated fraudster could still stage an appropriate scene. An appropriately lit matte image might even suffice.

Please note: A well-funded organization, like a government, can derive the keys from the TPM hardware using an electron microscope.
ixwtabout 3 hours ago
Keys could be stored in something like TPM on Camera, and could sign the image. The key could then be verified from the camera itself to prove the authenticity of the image.

If we as a society deemed it necessary, the camera manufacturer could also provide a list of keys for devices they have manufactured. And an image/key could be provided, and the manufacturer could verify the authenticity that way.

The TPM signing could be tied into the sensor hardware itself, making it difficult, but not impossible, to sign arbitrary images with the TPM.

No. You'd only ever be able to show that key material belonging to $specific_camera was used to sign/mark the image.

Was the camera manufacturer breached? Did somebody on the factory floor steal some keys during the provisioning step? Or did somebody build their own photo-sensor simulator and plug _that_ in to the camera's motherboard to feed it a "real" image? Before going _that_ far, just point the unmodified camera at a sufficiently high resolution display...
