WEEKLY DIGEST | DIAMOND SERVICE Quick recap of what we covered with you this week: **MRZ — the hidden killer of perfect documents** Even if the document looks flawless visually, algorithms often reject it precisely because of the machine-readable zone. One mistake in check digits, mismatch...

WEEKLY DIGEST | DIAMOND SERVICE Here's what we covered this week: **Night — The Best Fake Detector** Smartphones in the dark turn on aggressive processing: noise reduction kills natural grain, pulls shadows, and breaks color temperature. “Too clean” night shots immediately raise red flags...

NIGHT IS THE BEST FAKE DETECTOR ▪ Think it’s easier to shoot in the evening? Think again. Night photos are a real minefield for verification. In the dark, smartphones turn on their full “deep cleaning” mode: - Powerful noise reduction wipes out natural grain and turns skin into plastic -...

WHY IDENTICAL SHOOTING ANGLES RAISE RED FLAGS ▪ The most “correct” angle is often the most dangerous one. Because thousands of people before you have already shot exactly the same frame, following the same guides. ▪ Algorithms are great at spotting repetition. Same shooting angle, same...

SHOOTING «LIKE IN THE GUIDE»? THAT’S WHERE THE PROBLEM STARTS ▪ The most popular camera angle is often the most suspicious one. Because thousands of people before you already took the exact same shot. ▪ Algorithms have been looking not only at the file itself, but also at behavior patterns...

RE-SHOT THE PHOTO? YOU’VE ALREADY LEFT A TRACE ▪ One of the biggest giveaways is a “photo of a photo”. Screen → camera → another compression cycle. And with every round, the image loses not only quality, but also natural realism. ▪ What happens next? Digital garbage starts to appear: broken...

«ALMOST PERFECT» – THE MOST DANGEROUS LEVEL ▪ The logic is simple: the “cleaner” the file looks – the more questions it raises. And this is exactly where most people fail. ▪ Human vs system. Humans make slight shifts, micro-imperfections, inconsistencies. Algorithms know this and...

Weekly Digest | Diamond Service ▪ A quick recap of what we covered over the past days. ▪ Camera. A perfectly “clean” image is not a plus rolling shutter, sensor noise and aberrations – that’s the real norm when they’re missing – the file starts to stand out. ▪ Light. Flat lighting...

TOO PERFECT = ALREADY A RED FLAG ▪ Fun fact: a «perfectly new» document raises more suspicion than a slightly worn one. ▪ Wear logic. In reality everything ages: micro scratches, light abrasions, contact marks When none of this is present – the scene looks «unused» ▪ Edges. They are...

The background exposes you while you think everything is fine ▪ You nailed the main object and thought the background would “just work”? That’s exactly where it breaks ▪ Scene depth A camera never sees everything equally sharp there’s focus — and there’s falloff without it — the...

Diamond Service Weekly Digest ▪ What we covered last week. A quick recap. ▪ Too perfect Perfect lines, “sterile” geometry, lack of micro-deformations — and the file already looks like a constructed image, not reality ▪ JPEG 8×8 blocks, double compression, artifacts — the file keeps its...

THE FILE LOOKS FINE. THE COLOR DOESN’T. ▪ The most common case: details look clean, but the feeling that “something’s off” doesn’t go away. ▪ That’s color. ▪ Different profiles The image may exist in one color space, but be displayed in another. That’s where tones start to shift and...

What we broke down this week ▪ Covered the myth “printed = passed” Showed where it actually fails: printer, geometry, light. Spoiler – the camera doesn’t fix it, it makes it worse. ▪ Went deeper into geometry Angles, focal length, sharpness – that’s where most checks catch issues. ▪...

Case «Can you make a document for a Georgian?» The client came with a short request and minimal input. The task was to assemble a passport for a Georgian citizen — not tied to a real person, with randomized data. We broke the task down step by step: ▪ defined the correct document format...

Case Study | “Name exists. Photo exists. Passport – not yet.” A client came with a short request. There is a photo of a person and some basic data. The task – assemble a passport. The name and photo were provided immediately. An interesting detail: the client asked **not to copy an...
