Fake checks are one of the most common instruments used to commit fraud against consumers. This fraud is particularly costly for victims, since they generally loose thousands of dollars as well as being exposed to judicial proceedings. Currently, there is no existing solution to authenticate checks and detect fake ones instantly. Instead, banks must wait for a period of more than 48 hours to detect the scam. In this context, we propose a block chain based scheme to authenticate checks. More precisely, our approach helps the banks to share information about provided checks without exposing the banks’ customers’ personal data. A proof of concept of our scheme was realized using Python language and relying on Name coin block chain.
