The string 9d91003d4080b03d40742c819ea5228e is a 32‑character hexadecimal value. On first glance it resembles an MD5 or SHA‑1 cryptographic hash – a digital fingerprint that uniquely identifies an input of any length and returns a fixed‑size output. Like the MD5 hash of the word “password” yields 5f4dcc3b5aa765d61d8327deb882cf99 , this hash may be used to validate file integrity, encrypt sensitive data, or generate unique identifiers. However, a deeper investigation reveals that this sequence is not merely a hash of a user password or a file checksum; it functions as a Profile ID inside an ICC (International Color Consortium) color profile.

Often released under CC0 (Creative Commons Zero) , meaning it is in the public domain and free to use without restrictions. 9d91003d4080b03d40742c819ea5228e full

For instance, it appears in the metadata of an image titled "Dead Hamster Halloween Party" uploaded by a user named "havana" on some.pics . The same Profile ID appears in another image, "Dice Dragons Sold Out! - GamesExpo 2023," posted by user "darreninthenet". However, a deeper investigation reveals that this sequence

These numbers are the mathematical definitions of the uRGB color gamut. The "White Point" describes the color of light interpreted as pure white, while the "Matrix Columns" define the specific chromaticity coordinates of the red, green, and blue primaries that make up the color space. This allows any ICC-compliant software to reconstruct the exact shape and limits of the uRGB color space. The same Profile ID appears in another image,

As discussed in digital metadata forensics forums like the ExifTool Forum , finding an ICC profile signature such as this one helps trace whether multiple images originated from the same software pipeline or device architecture. While raw hardware components generate camera-specific profiles, web screen captures or images compressed through a unified Windows/Microsoft utility often standardize on this specific footprint. 2. Identifying Automated Post-Processing

An MD5 hash is always 128 bits long. Represented in hexadecimal form (our base-16 system), it appears as a 32-character string. The hash is a product of a deterministic function: the same input will always produce the exact same output hash. Even the smallest change to the input file (like flipping a single bit) will create an entirely different, unpredictable hash.
