How common are qrcode collisions? Faggot google has no real results.

it's not like qrcode is a hash algorithm

2^(number of black squares) = the number of combinations + whatever the corner things do.
Work it out for yourself and see how likely

but there's no limit to the number of black squares

a qrcode grows indefinetly larger as the amount of data it stores grows larger, you don't work with a limited number of bytes as in a hash algorithm, there's no collision

Do they? Hmm, kinda wanna read up on how QR-codes work now (not OP)

there is a number of predefined sizes, its not an automatically scalable thing, your application just gives you the most suitable version of the standard

>>55082108
ah ok

>>55082039
it's pretty cool how it does error tolerance and how the corner things work as anchors

definetly worth looking into

>>55081907
how can there be collisions? im pretty sure that decode(encode(data)) == data is guranteed by the standard

Plz does ne1 know how common are collisions in ascii?!

qrcode collision ? wtf ? it's like asking how common are json collision. It's nonsense.

QRCODE are actual binary data represented in an image that is easy to recognize for a computer. It's exactly the same thing as a barcode.

are certain qr codes illegal?

That's the assumption the entire DMCA runs on

If you encode illegal bytes into a QR code, then the QR code is illegal.
