In this presentation, a completely revisited secure data storage and transmission scheme ispresented. This new scheme is based on an agnostic selective encryption methods combinedwith fragmentation and dispersion. Discrete Wavelet Transform (DWT) is used as thepreprocessing method to determine the selection process before encryption and toguarantee the agnostic property of the protection. Also, General Purpose Graphic ProcessingUnit (GPGPU) is deployed to allow performance to be very efficient compared with fullencryption algorithms. During the protection process, the data is fragmented to be privatefragments with small storage space and public fragments with large storage space. Then thedispersion step will distribute the fragments to different storage environments aiming atutilizing the convenient and inexpensive cloud storage space while provide security for thedata. This design, with practical experimentations on different hardware configurations,provides strong level of protection and good performance at the same time plus flexiblestorage dispersion schemes.
