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
>>55081944
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?

>mfw certain combinations of bytes are illegal
>>55083750
That's the assumption the entire DMCA runs on
>>55082817
If you encode illegal bytes into a QR code, then the QR code is illegal.
