receive a user request for access to selected data;

identify which of the data storage devices have the subsets that correspond to the selected data;

determine which of the identified data storage devices satisfies the at least one criterion; and

4 . The system of claim 3 , wherein the at least one criterion includes a proximity between the user and the selected data storage device being the same as or less than a proximity between the user and any other of the data storage devices having a subset corresponding to data requested by the user.

5 . The system of claim 3 , wherein the at least one criterion includes a transfer rate between the selected data storage device and the user being the same as or higher than a transfer rate between the user and any other of the data storage devices having a subset corresponding to data requested by the user.

6 . The system of claim 1 , wherein the at least one data manager device is configured to

determine whether the user requires additional information regarding the data; and

select an additional one of the data storage devices for providing the user access to the at least one subset stored by the additional one of the data storage devices.

7 . The system of claim 1 , wherein the at least one data manager device is configured to

receive the data;

make the compressive measurements of the data.

8 . A method of managing data access, comprising the steps of:

segmenting compressive measurements of data into a plurality of subsets, wherein each of the subsets contains measurement information for facilitating a reconstruction of at least an approximation of the data;

providing at least a first one of the subsets to a first data storage device;

providing at least a second one of the subsets to a second data storage device; and

selecting at least one of the data storage devices, based on at least one criterion, for providing a user access to the at least one subset stored by the selected data storage device.

9 . The method of claim 8 , comprising

receiving a user request for access to selected data;

identifying which of the data storage devices have the subsets that correspond to the selected data; and

determining which of the identified data storage devices satisfies the at least one criterion.

10 . The method of claim 8 , wherein the at least one criterion is indicative of efficient access to the data by the user.

11 . The method of claim 10 , wherein the at least one criterion includes a proximity between the user and the selected data storage device being the same as or less than a proximity between the user and any other of the data storage devices having a subset corresponding to data requested by the user.

12 . The method of claim 10 , wherein the at least one criterion includes a transfer rate between the selected data storage device and the user being the same as or higher than a transfer rate between the user and any other of the data storage devices having a subset corresponding to data requested by the user.

13 . The method of claim 8 , comprising

determining whether the user requires additional information regarding the data; and

selecting an additional one of the data storage devices for providing the user access to the at least one subset stored by the additional one of the data storage devices.

14 . The method of claim 8 , comprising

receiving the data; and

making the compressive measurements of the data.

15 . A method of accessing data stored in a cloud computing system as compressive measurement information that has been segmented into a plurality of subsets, wherein each of the subsets contains measurement information for facilitating a reconstruction of at least an approximation of the data, the method comprising the steps of:

requesting access to the data;

obtaining access to at least a first one of the subsets from a data storage device, wherein the data storage device is selected, based on at least one criterion, from among a plurality of data storage devices each having at least one of the subsets; and

performing at least one computing function based on the first one of the subsets.

16 . The method of claim 15 , wherein the at least one criterion is indicative of efficient access to the data based on the requested access.

17 . The method of claim 16 , wherein the at least one criterion includes a proximity between a user device used for the requesting and the selected data storage device being the same as or less than a proximity between the user device and any other of the data storage devices having a subset corresponding to the data requested by the user.

18 . The method of claim 16 , wherein the at least one criterion includes a transfer rate between the selected data storage device and a user device used for the requesting being the same as or higher than a transfer rate between the user device and any other of the data storage devices having a subset corresponding to data requested by the user.

19 . The method of claim 15 , comprising

determining that additional information regarding the data is required based on the performed computing function; and

obtaining access to at least a second one of the subsets from an additional one of the data storage devices.

20 . The method of claim 19 , comprising requesting access to the additional information based on determining that the additional information is required.
