Yes. The date and time on a photo can be changed, often in a few taps, and the change may leave no visible mark. So the date you see is a claim, not proof. This post is for clients, PMCs (project management consultants), claims teams and engineers who must decide whether to trust a site photo. It explains where a photo's date is stored, how to check it on Android, iPhone and a computer, and what sound proof needs.
Yes: the date on a photo can be changed
A photo does not carry one date. It carries several, and each lives in a different place. Some are written by the camera. Some are written by the phone or the computer. One may simply be printed on the picture.
Anyone who holds the file can edit most of these. Photo apps even offer the option as a normal feature, for example when you travel across time zones. Google Photos explains how to edit a photo's date and time, and Apple's iPhone guide covers photo information. Both are meant for honest corrections. The same kind of change can be made on purpose.
The result is that two people can look at copies of the same photo, taken through different apps or chat routes, and see different dates.
Where the date lives, weakest to strongest
Think of a photo's date as a ladder. The lower rungs are easy to change. The upper rungs are harder, but none is perfect unless something outside the phone backs it up.
1. A date typed or printed on the picture
A date written over the image is only pixels. A person can type it in any app, or write it in a caption. It shows what someone wanted you to read, nothing more.
2. The phone clock at the time of capture
A normal camera app takes the time from the phone's clock. If the clock is set to another day, the photo is saved with that day. The phone does not question it. This is the oldest trick, and it needs no tools.
3. File dates on the phone or computer
Every file has dates such as created and modified. These describe the file on that device, not the moment of capture. Copying, downloading or saving a file usually gives it a new date. They are useful clues, but they tell you about the file's journey.
4. Photo details (EXIF) inside the file
EXIF is the information a camera writes inside the photo: capture time, and sometimes GPS location and device. It is more useful than a file date. But editing tools can rewrite it, and photo apps can adjust it. It also disappears when many chat apps compress a photo, so a forwarded picture often arrives with no capture time at all.
5. A time stamped at capture and backed by a record
The strongest case is a photo taken inside an app that stamps the time at the shutter, stores a record of the job, and keeps a fingerprint of the file. Then a change to the file can be detected. This is a matter of how the photo was captured, not what it looks like.
How to check on Android, iPhone and a computer
Checking takes two minutes. Do it on the file you actually received, not on a screenshot of it.
On Android
- Open the photo in your gallery or photos app and open its details or info panel. Google's Photos Help describes where the date is shown.
- Note the date, time and location shown. Compare them with what the sender claims.
- Check how the photo reached you. A photo sent as a normal chat image has usually lost its original details.
On iPhone
- Open the photo in Photos and open its information view. Apple's guide to photo and video information shows what is displayed.
- Read the date, time and place. Photo apps can adjust these, so a shown date can be an edited one.
- Ask for the original file, not a forward, if anything looks different.
On a computer
- Copy the received file to your computer without opening and re-saving it.
- Open the file's properties or details in your file manager. Read the capture date if present, and the created and modified dates.
- Compare them. A modified date long after the claimed capture date deserves a question.
None of these views proves a date is true. They show what the file says, and whether the file says it consistently.
Signs that something may be wrong
Look at the date together with the rest of the photo and the story around it.
- Dates that disagree: the capture date, the file date and the date in the message do not match.
- Missing details: no capture time and no location on a photo that was meant to prove a site visit.
- A modified date much later: the file was changed long after the work was said to be done.
- A date printed on the picture only: it looks tidy, but nothing in the file agrees with it.
- Same scene, different days: shadows, weather, vehicles or materials differ from the claimed date.
- Screenshots or forwards: the picture was captured from another screen, or passed through a chat app, so the original is gone.
- A location that does not fit: the place on the photo is far from the site, or it has jumped between photos taken minutes apart.
These are reasons to ask, not proof. Phones lose track of time zones. GPS drifts indoors and near tall buildings. Chat apps remove details without any bad intent. Ask the person to explain and send the original before you accuse anyone.
What sound proof needs
Because every low rung can be edited, sound proof comes from how the photo was made, not from how it looks. Look for these.
- Capture inside the tool: the photo comes from the app's own camera, not from the gallery, so an old picture cannot be picked and passed off as new.
- Time burned in at the shutter: the stamp is part of the image when it is taken, not added later by the sender.
- Location with a warning: GPS is recorded, and a fake location is flagged rather than silently accepted.
- A fingerprint: a short code worked out from the file, so any later change shows up.
- A check outside the sender's hands: the reviewer can verify without asking the sender, and without an account.
Even then, whether a court, insurer or client accepts a photo is their decision. Good proof makes their decision easier. It does not make it for them. For the field side of this, see how to stop employees uploading old photos, and for claims, how to take photos for an insurance claim in India.
How Verafii does it
Verafii is a live-capture camera and report app. It is built around the rungs above, so the date does not depend on a person's word.
- Live capture only: photos and video come from Verafii's own camera. There is no gallery and no file picker, and the app never asks for photo-library access. An old photo cannot be added.
- GPS and time stamp: burned into every photo at the shutter.
- Fake GPS flagged: on Android and iPhone, a photo taken with a fake location is flagged on the photo, the report, the verify page and the dashboard. It is flagged, not blocked.
- One fingerprint: one SHA-256 fingerprint covers the PDF, every photo and every video. The report is tamper-evident: a changed file no longer matches.
- One-tap report: a PDF with location, device, time and a QR code, made before leaving the site.
How to check a Verafii report
- Scan the QR code on the report with any phone camera. It opens a public verification page. No account and no app is needed.
- Read the page. It shows the record for that job, including any fake-GPS flag.
- Take the file you were sent, the PDF, a photo or a video, and drop it onto the page. It is fingerprinted in your browser, and nothing is uploaded.
- A match means the file is untouched. No match means it differs from what was recorded, so ask the sender for the original.
The same steps are on how to check a Verafii report and in our post on scanning the QR and dropping in the file.

What a check can't prove
A check shows that a file is the same as the one recorded. It cannot show everything.
- That the work is good: a true date and place say when and where the photo was taken, not whether the work meets the specification.
- That the scene was not staged: a live photo of the wrong thing is still live. A reviewer must still look at what is in the frame.
- That GPS is perfect: GPS drifts indoors and near tall buildings. A flag is a reason to ask, and a missing flag is not a guarantee.
- That someone accepts it: no portal, department, insurer or client is bound to accept any photo or report. Verafii is not an official app and does not upload to a government portal.
- Anything before the photo was taken: the record starts at capture.
For contractor bills and government work, read geo-tagged photos for bills for what Verafii's photos contain and where the department's own rules still decide.
Frequently asked questions
Can the date and time of a photo be changed?
Yes. The phone clock can be set to another day before capture, and photo details and file dates can be edited afterwards. Photo apps from Google and Apple include date editing for honest corrections. A date printed on the picture is only text, so treat any date as a claim until it is backed by a record.
How can I check the date a photo was taken?
Open the photo's details on Android or iPhone, or the file properties on a computer, and read the capture date. Then compare it with the file dates and with how the photo reached you. Apple's guide and Google's Photos Help show where the details are.
Why does a photo sent on WhatsApp show no date or location?
Chat apps often compress photos and remove the details stored inside them, including capture time and location. The picture arrives, but the evidence of when and where does not. Ask for the original file, or use a tool that burns the time and place into the image at capture.
Does Verafii stop fake GPS?
No. On Android and iPhone, a photo taken with a fake location is flagged on the photo, the report, the verify page and the dashboard. The flag tells the reviewer to ask a question. It does not prove what happened, and GPS can also drift honestly indoors.
How do I verify a Verafii report?
Scan the QR code on the report to open the public verification page. No account or app is needed. You can also drop the file you received onto the page; it is fingerprinted in your browser, nothing is uploaded, and a match means it is untouched.
Will Verafii make sure my photos are accepted?
No. Whether a client, insurer, department or court accepts a photo is their decision. Verafii gives them a photo captured live, with GPS and time burned in, a fake-GPS flag where it applies, and a fingerprint they can check themselves.
Is a photo with a date stamp on it proof of the date?
No. A stamp typed or added on top of an existing picture can show any date. It is stronger when the stamp is applied at the shutter inside a camera that cannot take gallery photos, and when the file can be checked afterwards.
