Stop employees uploading old photos: use live capture

How old photos get into work reports

Most old photos are not a plot. They are a shortcut taken on a tired evening when the report is due. Knowing the routes helps you close them. Here are the common ones, from the easiest to spot to the hardest.

1. The same photo sent again

A crew sends Monday's photo of a finished trench as Thursday's progress. Nothing about the image changes, so you only catch it if you remember the frame.

2. A photo from another site or another job

A similar tower, panel row or slab from a different site is sent as this one. Many sites look alike, so a quick glance will not tell them apart.

3. A borrowed or forwarded photo

A colleague or a subcontractor shares a picture over chat, and it goes into the report as the sender's own. The person who took it was never at your site.

4. A screenshot or a typed-in stamp

Some apps let you pick any picture from the gallery and add today's date and place on top. The stamp is then only text. It shows when the file was edited, not when the scene was photographed.

5. A changed phone clock

Set the phone's date back, take a photo, and the file carries the wrong date. Chat apps also strip location data from photos, so the reviewer sees a picture with no place at all. Apple's own guide notes that shared photos can carry location metadata, which is why apps and chat tools treat it differently.

The first four routes all share one step: the photo came from the gallery or a chat, not from a camera at the site. Route five needs a different fix, and the later sections cover it.

A setting vs a design: why "live only" toggles fall short

Some apps offer a "live capture only" option, or a rule that says photos must be fresh. Settings like these help, but they have a weakness. Someone has to switch them on, and someone can switch them off, often the same person you are trying to check.

A setting also leaves the gallery door in place. The app can still ask for photo-library access, and the phone still grants it. Then every old picture on the phone sits one tap away.

A design removes the door. If the app has no gallery button, no file picker and no photo-library permission, there is nothing to configure and nothing to forget. The only way to add a photo is to take one.

That is the difference to look for when you choose an app:

• A setting: can be off by mistake, by a new admin, or on one phone only.
• A design: applies to every user, every phone and every report, from the first day.

No method stops everything, and this one does not either. But it makes the lazy shortcut impossible, which is where most old photos come from.

What live capture only means in Verafii

In Verafii, photos and video come from the app's own camera. There is no gallery and no file picker. The app never asks for photo-library access on the phone.

At the moment of the shutter, the app burns the GPS location and the time into the image. The stamp is part of the picture from that second, not added later. It is the same on Android and iPhone.

Two further parts matter to a manager:

• Fake GPS is flagged: if someone takes a photo with a fake location on Android or iPhone, the photo, the report, the verify page and the dashboard show a flag. It is flagged, not blocked, so you still see the photo and can ask about it. Our post on catching fake GPS fairly covers how to raise it with a crew.
• One job, one record: every photo, video and note lands in one numbered session tied to the site, so a photo from a different job does not slip into this one.

The result is a GPS camera photo report where each picture was taken live, at the place shown, at the time shown.

How to check a photo you have been sent

Before you change any tool, check what you hold now. The method depends on how the photo reached you.

A photo forwarded on a chat app

1. Treat it as a picture only. Chat apps usually drop the location and time, so it proves little on its own. Our post on why chat photos are not enough explains this.
2. Ask the sender for the original file or a report made from it.
3. Compare the frame with earlier photos of the same spot for the same fence, pole, wall or sky.

A photo with a stamp on it

1. Ask where the stamp came from: a camera app that stamps at capture, or a text added to a gallery picture.
2. Look at the stamp style. If the date sits in a different font or position from other photos in the set, ask why.
3. Ask for the next photo from the same spot, taken now.

A PDF report

1. Check whether it carries a QR code or any way to verify it.
2. If it does, scan it and read the result, as described in the Verafii section below.
3. If it does not, treat it as a document made by hand, and ask for the source files.

Signs that something may be wrong

None of these proves an old photo. Each is a reason to ask a question.

• No location or time on the image, or a time that is the same on every photo in a set.
• Weather or light that does not match the day: bright sun in a photo for a day that was rainy at the site.
• The same view with only small changes, such as one crop or a slightly different zoom.
• Shadows pointing the wrong way for the time of day claimed.
• Workers, vehicles or materials that were not on site that day, or a board that shows an older date.
• Several photos arriving together with times far apart, such as a day's work sent in one batch.
• A stamp in a different style from the rest of the crew's photos.

These are reasons to ask, not proof. A phone can be wrong about location, and a batch may be a real day sent late. Ask first, and be fair to the person who took the photo.

What sound proof needs

Good proof of a site photo has four parts: where it was taken, when it was taken, that it came from a camera at that moment, and that nobody changed it afterwards.

A typed stamp gives the first two on trust only. A gallery import breaks the third. An edited or forwarded file breaks the fourth. Live capture covers the third, the stamp at the shutter covers the first two, and a fingerprint on the file covers the fourth.

Whether a client, department or insurer accepts a photo is their decision. What you can do is give them a record they can check themselves, without asking you to vouch for it.

No signal? Capture offline

The usual objection to a camera with no gallery is that site signal is poor. A crew on a rooftop, a tower in the hills or a basement may have no network at all. If the app needed a connection to take a photo, people would go back to their own camera and the gallery.

Verafii works offline. The crew captures with no signal, and the photos upload when the phone is back online. The GPS and time are stamped at the shutter, so they come from the moment of capture, not from the moment of upload.

This matters because it removes the reason to cheat. Nobody needs to "take it with the normal camera and send it later". Ask the crew to open the app online at least once a day, so that waiting photos reach the dashboard.

A privacy bonus: no access to personal photos

An app that reads the photo library can see everything in it: family pictures, ID card photos, bank screenshots. Many field staff use their own phones for work, and they notice.

Because Verafii never asks for photo-library access, it cannot read those pictures. That makes the app easier to ask a crew to install on a personal phone. It also helps you answer the question "will my employer see my photos?" with a plain no.

This is a side benefit. The main reason is still proof. But a crew that trusts the app is more likely to use it every day.

How Verafii lets anyone check a report

Verafii turns a job into a PDF report with a QR code, made with one tap before the crew leaves the site. Anyone can check it, with no account and no app. The full method is in our post on verifying a site report with the QR or the file.

How to check a Verafii report

1. Scan the QR code on the report with any phone camera. It opens the public verification page.
2. Read the details shown: location, device, time and any fake-GPS flag.
3. To check the file you were sent, drop it into the verify page. The check runs in your browser and nothing is uploaded.
4. A match means the file is untouched. One SHA-256 fingerprint covers the PDF, every photo and every video.

You can also read how this works on the page to check a Verafii report.

What live capture can't stop

Live capture stops old photos from the gallery. It does not stop a staged scene. Someone can still take a fresh photo of an old, finished job, of a different but similar site, or of a screen or printout held up to the camera. The photo is live, but the scene is not the work claimed.

A GPS stamp also drifts indoors and near tall buildings, so a small offset is not a lie. Ask before you accuse.

Here is what to do about staging:

• Ask for a wide shot and a close-up of the same item, so the work and its surroundings both show.
• Put a dated object in frame, such as a board with the day's date and the job number written on it.
• Vary the angle, and ask for a spot that is hard to prepare in advance.
• Use live video with audio for key stages, such as pit depth or a final test.
• Cross-check against the record: the job session, the numbered sequence and any earlier photos of the same spot.
• Visit at random: a short surprise visit by a supervisor is still the best check.

Verafii is not a replacement for a site visit, and it does not upload to any government portal or replace an official app. Whether a client or department accepts a photo is for them to decide. For a wider routine, see our site inspection app page.
