Outsourcing data to the cloud becomes a trend for the users to reduce database management and maintenance cost. However, storing data on the cloud brings many security problems. Data privacy and query authentication are two critical issues to be resolved. Specially, they are important to aggregate queries of cloud data. The data owner must keep the sensitive data hidden and only the aggregate result...
In order to solve the ill-posed problem in the process of reconstructing the spectral reflectance of the traditional matrix R method, a regularization matrix R method was proposed in this paper. Through analyzing the ill-posed equation of matrix R to reconstruct the spectral reflectance, the Tikhonov regularization method was researched to restrict the ill-posed problem to solve the Moore-Penrose...
