Secure information retrieval and reveal for mobile apparatus based on 2D Barcode digital signature

This paper introduces the mobile apparatus must make their best tradeoffs for the innate limitations of the physical properties and will benefit from the cloud services via wireless broadband access. Then a secure information retrieval and reveal framework based on two-dimensional barcode digital signature scheme is proposed for mobile apparatus. In addition to the secure protocol with cipher retrieval and barcode reveal presented, a case study is also presented to demonstrate how the framework is feasible and applicable especially for mobile commerce.
