Abstract

Various cybercrimes are major threats to Ebusiness. We propose an offline oblivious data distribution framework that preserves the sender's security and the receiver's privacy using tamper-proof smart cards. This framework provides persistent content protections from digital piracy and promises private content consumption. In contrast to all known oblivious transfer protocols that require public key operations, our approach does not require any public/private key operation and consequently it is computationally very efficient. It is particularly useful for data-intensive and data-rich environments. In addition, our framework is flexible to manage various business scenarios and diverse generalized oblivious transfer models.
