Abstract

Presented are cloud storage architectures for private data among terminals with enhanced capability of data privacy and survivability. Pre-processing for storing data in IP cloud comprises: transforming multiple first data sets into multiple second data sets at an uploading site, wherein one of said second data sets comprises a weighted sum of said first data sets; storing said second data sets in an IP cloud via IP connectivity; and storing multiple data storages linking to said second data sets at said uploading site. In accordance with an embodiment post processing may comprise recovering said second data sets at a downloading site via IP network.

Claims

1. An apparatus comprising:

an image sensor to obtain a visual object;

a buffer to store the obtained visual object; and

a pre-processor device having K input ports and K output ports, N of the K input ports being connected to input streams processed by a pre-processing application operating on the buffer, the K output ports providing output streams for transmission to a cloud storage site via a wireless interface,

wherein N and K are positive integers and N≤

K, and

wherein the output streams are wavefront (WF) components of a WF muxing transform on the input streams such that the WF components are mutually orthogonal.

2. The apparatus of claim 1 wherein the pre-processor device comprises:

a segmentation processor to segment an original stream corresponding to the obtained visual object into the input streams; and

a WF device to convert the input streams into the output streams using an orthogonal matrix.

3. The apparatus of claim 1 further comprising:

a plurality of local buffers associated with applications related to synchronization management of cloud storage at the cloud storage site.

4. The apparatus of claim 1 wherein at least one of the K input ports is grounded or connected to a known stream.

5. The apparatus of claim 1 wherein the WF muxing transform is implemented by one of a Hadamard transform, a Fourier transform, and a full-rank matrix.

6. The apparatus of claim 1 wherein the WF muxing transform corresponds to an erasure coding transform.

7. The apparatus of claim 6 wherein the WF muxing transform corresponds to a polynomial of a Reed-Solomon code.

8. The apparatus of claim 6 wherein the input and output streams are complex data streams.

9. The apparatus of claim 1 wherein the visual object is an image or a video clip.

10. The apparatus of claim 6 wherein the visual object is a plurality of images or a plurality of video clips.

19. The apparatus of claim 1 wherein the visual object is an image or a video clip.

20. The apparatus of claim 6 wherein the visual object is a plurality of images or a plurality of video clips.

11. An apparatus comprising:

a wireless interface to connect to a wireless network to retrieve data streams representing a visual object from a cloud storage site;

a buffer to store the data streams; and

a post-processor device having K input ports and K output ports, the K input ports being connected to the buffer to receive the data streams processed by a post-processing application operating on the buffer, N of the K output ports providing output streams for displaying the visual object,

wherein N and K are positive integers and N≤

K, and

wherein the output streams are wavefront (WF) components of a WF de-muxing transform on the data streams such that the WF components are mutually orthogonal.

12. The apparatus of claim 11 wherein the post-processor device comprises:

a WF de-muxing device to convert the data streams into the output streams using an inverse orthogonal matrix; and

a de-segmentation processor to de-segment the output streams into a reconstituted stream corresponding to the visual object.

13. The apparatus of claim 11 further comprising:

a plurality of local buffers associated with applications related to synchronization management of cloud storage at the cloud storage site.

14. The apparatus of claim 11 wherein at least one of the K input ports is grounded or left unused.

15. The apparatus of claim 11 wherein the WF de-muxing transform is implemented by an inverse of one of a Hadamard transform, a Fourier transform, and a full-rank matrix.

16. The apparatus of claim 11 wherein the WF de-muxing transform corresponds to an inverse erasure coding transform.

17. The apparatus of claim 11 wherein the WF de-muxing transform corresponds to an inverse of a polynomial of a Reed-Solomon code.

18. The apparatus of claim 11 wherein the data and output streams are complex data streams.
