Abstract
A method for secure data storage in a cloud storage infrastructure comprises providing a set of first upload files to be stored in the cloud storage infrastructure, providing a set of first random noise files, splitting each file of the two sets into a group of fragments, recombining the fragments by randomly intermixing fragments from different groups thus generating a set of second upload files, encrypting each second upload file with a first encryption key and storing each first encryption key in a secure storage location, storing reconstruction information about the set of first upload files, the splitting, the recombining and the first encryption keys in the secure storage location, uploading each second upload file to a respective temporary cloud storage location, repeatedly moving each uploaded second upload file to a new temporary cloud storage location in predetermined intervals of time.
