How to Send an ID Photo Without Exposing Your ID Number

Someone asks for "a photo of your ID, front and back", and you send it in twenty seconds without wondering where it ends up. An ID photo shows your full name, address, date of birth and your national ID number, which is exactly what someone needs to try to pass as you. You can send an ID safely if you hide what the other side doesn't need and mark the photo for its purpose.

Remember this: an ID number is not a password you can change. It stays with you for life.

What an exposed ID number can mean

A single number rarely empties a bank account. The risk is the full set: your name, address, date of birth and a photo of your face in one image. Anyone holding that has most of what a weak identity check asks for.

You can't cancel an ID number the way you block a stolen card, so the time to be careful is before you send. How many places already hold a photo of your ID?

When you really have to send it, and when you don't

Legitimate requests exist: a bank, a rental contract, a courier collecting a parcel, a hotel check-in. Then there are requests made out of habit or over an unsafe channel: a "buyer" who wants to "verify" you, a job ad from a company you can't identify, a chat with a stranger.

Ask before you send anything:

What exactly do they need it for? A vague answer is a warning sign.
Do they need the ID number? Often they only need your name and photo, or proof of age.
Through what channel? A company's own form beats a message on a chat app.

How to hide what the recipient doesn't need

The practical rule: show only what is asked. If they check your name and face, cover the ID number and document number. If they only check your age, cover almost everything.

Photograph the document on a plain surface, with no other papers in the frame.
Cover what shouldn't be seen: ID number, document number, sometimes the address. Use a real blur applied to the image, not a marker line drawn over text that can be removed later.
Save the hidden version as a new file and send that one. Keep the original to yourself.
Zoom in on the final image. Text blurred too lightly can sometimes still be read.
Delete the copy from the chat and the gallery once it's no longer needed, if the platform allows it.

A habit many people use: write the purpose and date on the copy or in the message ("for the lease with X only, November 7"). That way a photo that reaches other hands no longer works as a general-purpose copy.

What BlurifyRo does here

If you don't want to do it all by hand, BlurifyRo hides personal data in photos and screenshots right on your phone. The free version automatically detects phone numbers, emails, links and amounts. The Pro version also detects national ID numbers, cards, IBANs, names and addresses. For something the app didn't recognise, like a face or a QR code, you draw a box around it yourself.

The photo is processed on your phone, with no account and no upload to a server. The app is available on iPhone and Android, and you'll find it on the Cleoda Labs apps page.

What to do if you already sent your ID unhidden

Don't panic; it's very common. Ask the company or person to delete the file, if it's a place you trust to do that. Delete the photo from your own chat and gallery. After that, watch for unusual messages or calls asking you for data or confirmations you didn't request.

You can't know what happened to a photo once it has left your phone, which is why it's worth asking yourself next time: "Do they really need everything that's visible here?"

Common mistakes

A marker line drawn over text. In an editor that keeps layers, the line can be moved and the text is still underneath. Export the image as a new flattened file and check it.

One photo sent to several people. If the same file reaches three companies, there are three places it can leak from. Make a fresh copy for each one.

The photo left in the gallery and in backups. If you send the picture and forget it, it sits in your gallery, synced to the cloud. Delete it when it's no longer needed.

ID sent in chats with strangers. If someone you've never met asks for your ID, the safe answer is no.

In short

Before you send an ID, ask why it's needed, hide what isn't asked for, send a fresh copy and delete it afterwards. If you want the hiding step done in a few taps, BlurifyRo does it on your phone without sending the photo anywhere. You get an image you can send without giving more than you were asked for.

Send what's asked, nothing more.

Frequently asked questions

What can someone do with the ID number in a photo of your ID?

On its own it rarely does much, but combined with your name, address and face it can help someone try to pass as you. That's why it's worth sending only what's asked for.

How do I send an ID photo without showing the ID number?

Cover the ID and document numbers with a real blur applied to the image, save a new copy and zoom in to check it. Send the copy, not the original.

Can BlurifyRo hide an ID number?

Yes, automatic detection of national ID numbers, cards, IBANs, names and addresses is part of Pro. The free version detects phone numbers, emails, links and amounts.

Is my photo uploaded when I process it in BlurifyRo?

No. Processing happens on your phone, with no account and no upload to a server.
