Mobile Coupons Using Blockchain Technology
Blockchain is a kind of non-tampered global database which provides digital booklets recording financial transactions and valuables such as birth certificates, asset ownerships, education diplomas, medical procedures, ballots and so on. Among the financial activities, coupons have longtime been used for marketing in business and mobile coupons are replacing paper ones due to the popularity of mobile devices gradually. The strong interactions between people and the use of mobile coupons have together inspired Peer to Peer (P2P) sharing and raised the usage of coupons with peer trusts. Adding bonus feedback mechanisms to mobile coupons may effectively prompt transfers of unused coupons to potential users.
The valuable information including contents and feedback bonus in mobile coupons need to be protected against security threats like forgery or tampering. The limitations of storage space, computing power, and transmission bandwidth in mobile devices generally constrain strong protection mechanisms as used in desktop computers. Therefore, in this study, the technique of Hash Chain is combined with the blockchain technology to verify forgery coupons and to enable both storage and transmission of low-computation requirements. Our scheme exemplifies P2P sharing spirit with the nature of highly distribution in blockchain. Verifications are handed by the distributed miners in the P2P environment, which reduces the opportunity of conspiracy among evil-doers. In addition, eavesdroppers have no way to steal valuable information due to the anonymous nature of blockchains so that transmissions are entirely secured in the proposed scheme.
