Mobile Money Wallet Security against Insider Attack Using ID-Based Cryptographic Primitive with Equality Test

An attack continuum perpetuated by an insider (Mobile Money Wallet Service Provider) is paramount in this era of data intelligent and analytics. Mobile Money Wallet Service Providers (MMWSP) are entrusted to keep our sensitive information such as tokens and other mobile financial transactions secured for users to query and exchange token information. However, it is possible for the mobile money wallet service provider (insider) to peddle with user's data stored on it's server for economic gains. we put forward a novel mobile money wallet security against insider attack using identity based cryptography. Our novel scheme resist an insider from peddling user's data for economic gains. The scheme adopts the witness based cryptographic primitive. Finally, The security of our scheme is demonstrated by the use of random oracle model.
