Report verification
Was this report issued by Illevante, exactly as it is?
Enter the report number or scan the QR code printed on it. We show you the copy we signed the moment it was issued, so you can compare it with the paper in your hands.
How we sign our reports
Every report carries a signature no one else can make
We sign the report’s data itself, not its image: any change to it, even a single digit, invalidates the signature.
01
Data from our servers
We issue a report only for the result of a check our servers ran, sealed at the moment of the check, so there’s no report for data someone typed in by hand.
02
Two unforgeable signatures
We sign the report’s data with Ed25519 and print the signature at the bottom of every page, and we certify the PDF file itself with a PAdES signature that allows no changes. The private keys never leave our servers.
03
QR code and number
The code at the top of the report opens this page on its number, and the number alone is enough for anyone without a camera.
04
Verify from anywhere
Open the file in Adobe Acrobat Reader and it tells you whether it’s been altered, offline; or verify here and we show you the signed copy to compare.
Public key
Verify it yourself, without trusting us
Adobe Acrobat Reader verifies the PDF file on its own, offline, and any tool that supports Ed25519 can verify the signed data with this key.
The file itself is certified (PAdES)
Every PDF file we issue carries a digital signature inside it that certifies it and prevents changes. Open it in Adobe Acrobat Reader and you’ll see it’s certified by Illevante Internet Services LLC and hasn’t been altered since it was signed; any later change, even a single character, shows a warning that the file has been altered, without needing our site.
