It is typically found within the ICC_Profile section of an image's metadata (EXIF/IPTC data). Technical Application
The full data package of this hash contains deterministic matrix calculations used to translate digital data into visible colors. According to technical documentation on the MeVer Image Verification Assistant , the profile always retains these precise RGB primary values: : 0.43604 0.22244 0.0139 Green Matrix Column : 0.3851 0.71693 0.09708 Blue Matrix Column : 0.14307 0.06062 0.71393
Understanding uRGB and the Profile ID: 9d91003d4080b03d40742c819ea5228e
When an image is saved with a "full" uRGB profile, it embeds specific color rendering matrices: : Unknown / Generic ( hand ) Primary Platform : Microsoft Corporation Rendering Intent : Perceptual 9d91003d4080b03d40742c819ea5228e full
Looks for secondary compression traces left behind when an object is pasted from another photo.
Common in web and mobile environments to ensure a "standard" look across different screens.
Overview
A single changed bit in a file changes the entire hash, making it an excellent way to track specific file versions.
For technical readers, here is a practical workflow to extract the uRGB profile from a JPEG file and verify its MD5 against the stored Profile ID.
Online hash‑reversal databases maintain dictionaries of millions of pre‑computed hash–plaintext pairs. Querying the hash 40b63e17729530dda8e62bcd63116259 on md5.gromweb.com returns the plaintext string 9d91003d4080b03d40742c819ea5228e . This indicates that the , not the hash itself. In other words: It is typically found within the ICC_Profile section
Below is an in-depth article exploring what this profile represents, its technical specifications, and why it appears in metadata forensic reports.
Use this to extract the Profile ID and check for other "composite tags" that might indicate manipulation.
: Free web platforms like Compress-or-Die’s Analysis Tool allow users to drag and drop images to see hidden color space blocks instantly. Common in web and mobile environments to ensure
The uRGB profile utilizes specific matrix transformations to translate digital values to visible light, with key settings including a rendering intent and a white point of 0.9505, 1, 1.089 . The color matrix columns (Red: 0.43604, 0.22244, 0.0139; Green: 0.3851, 0.71693, 0.09708; Blue: 0.14307, 0.06062, 0.71393) define its precise color mapping. Image Verification Assistant - MeVer
