    Patent number: 10289862
    Abstract: A method of storing and retrieving a set of original data (E1, . . . , En) in and from a plurality of remote servers (SP1, . . . , SPI+1), comprises a coding step which consists in creating a set of coded data (S1, . . . , SN) from the set of original data (E1, . . . , En), a storing step which consists in storing the set of coded data (S1, . . . , SN) into the plurality of remote servers (SP1, . . . , SPI+1). Each server (SP1, . . . , SPI+1) of the said plurality of servers stores only a respective part of the set of coded data (S1, . . . , SN) and the method comprises a step which consists in generating a table (T1, T2) which indicates which respective part of the set of coded data (S1, . . . , SN) is stored in which server of the said plurality of remote servers (SP1, . . . , SPI+1).
