In this case, this specific fingerprint—or "Profile ID"—is embedded within an ICC (International Color Consortium) profile. An ICC profile is a small, standardized file that acts as a translator, telling your monitor, printer, or other device how to interpret and reproduce colors accurately. Think of it as a set of instructions that ensures the deep red you see on your screen is the same deep red that comes out of the printer.
Imagine you’re a sysadmin. A user reports the server is slow. You run top and see a process named exactly 9d91003d4080b03d40742c819ea5228e consuming 90% CPU. You kill it, but it restarts — classic crypto miner behavior.

If you want to see if your photos contain this specific Profile ID, you can follow these steps: 9d91003d4080b03d40742c819ea5228e top
Algorithms like use deep learning filters (such as Noiseprint++) to isolate altered image boundaries. The presence of a uniform uRGB profile profile ID tells the software that the image container structure conforms to standard Microsoft rendering systems. If certain pixels have divergent color space matrices while the global metadata points to this specific Profile ID, it acts as a red flag for localized image manipulation. 2.

Once you provide that, I can write a structured, referenced, and technically accurate paper. Imagine you’re a sysadmin
The identifier is the specific Profile ID for the uRGB (uncalibrated RGB) color profile. This profile is frequently embedded in image metadata and documents to define how colors are rendered across different devices.
Given the potential risks associated with this digital identifier and its related components, organizations and individual users should adopt the following proactive security measures:
The hash is the standardized unique identifier (Profile ID) generated by tools like ExifTool when reading the uRGB color profile. A deep breakdown of this specific profile’s structural data reveals: Profile Description: uRGB Profile Class: Display Device Profile Color Space: RGB Primary Platform: Microsoft Corporation Device Manufacturer/Model: Unknown (saws) / ctrl Profile Copyright: Public Domain (CC0) You kill it, but it restarts — classic
The most consistent and verifiable appearance of this hash is within the metadata of digital images hosted on the platform some.pics . A deep dive into the EXIF data of specific images reveals that 9d91003d4080b03d40742c819ea5228e is used as a for an ICC (International Color Consortium) color profile.
The uRGB profile bypasses this bloat. It features an incredibly compact 96-byte Red, Green, and Blue Tone Reproduction Curve (TRC). By utilizing a streamlined data array, it minimizes the payload of individual image files. This makes it a top choice for:
