The increasingly matured mobile commerce enriches our daily lives. Mobile ticketing, a process that allows consumers to order, make payment, acquire, and authenticate tickets using their mobile phones, will become popular since it can be conducted from anywhere and at anytime. In addition to the convenience of use, the fabrication and distribution costs of traditional paper-tickets can be greatly reduced with mobile tickets. Many applications, such as traffic tickets, concert tickets, movie tickets, and so on, may take the advantages of mobile ticketing. Such tickets, in their paper-forms, can be transferred to anyone before use since no specific identity is recorded in these tickets. Nevertheless, current schemes restrict mobile tickets to be non-transferable because the transferring will result in the tickets being invalidated. To overcome the non-transferability problem, we use the idea of digital rights managements to separate the content and the usage-rules of mobile tickets, and propose a transferrable mobile ticketing scheme. The usage-rule, i.e. the rights object of the ticket, registers the ticket identification and a hashed number comprising an issuer’s random number and the International Mobile Equipment Identity (IMEI) of the ticket owner. The rights object is independently issued by a trusted third party. When a ticket is transferred, the issuer will be notified and he will modify the rights object with a new hash value, computed from a new random number and the IMEI of the new owner who receives the transferred ticket. Therefore, mobile tickets are secured and transferrable in our proposed mobile ticketing scheme.
