The matrix barcodes known as Quick Response
(QR) codes, which are enable us to import printed digital information
into smartphone or cell phone through its digital camera easily, are rapidly becoming widespread
not only Japan but also Asia, Europe and America.
Without typing long characters by hands, a URL of desired site is read
in smartphone only pressing buttons in a few times.
However, an attacker is easily able to lead malcious websites by putting
a unautheticated QR code on a authenticated QR code.
We study the tamper detection, which is performed by digital signature
system based on public key cryptography, of QR code.
In digital signature system, a hash value of a message is calculated firstly, and
then the hash value is encrypted by a secret key which is a pair of public
key cryptography system. Then, a sender sends the message and the encrypted hash
value to a receiver. In the receiver side, the hash value of a sent message
is calculated and the hash value with encrypted is decrypted using a public
key which is a pair of public key cryptography system. The receiver can
detect modification of the message by comparing the two hash values. In
this situation, the problem is how the encrypted hash value is carryed
with QR code. In this paper, we use Wet Paper code to carry it on QR
code. We invesitigated the feasibility of our idea in the experiments, and confirmed that the information hiding based on Wet Paper code to QR
code can be realised when we provide an image processing technique to
read cell informaion of QR code with high accuracy. |
