Mobile Scanner via Private Data on Cloud

摘要

Presented are cloud storage architectures for private data of scanned documents uploaded from smart phone 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 data in multiple data storages linking to said second data sets at said uploading site. In accordance with an embodiment of present invention post processing may comprise recovering said second data sets at a downloading site via IP network.

1. A cloud data storage system for storing input data of scanned documents to IP cloud comprising a pre-processing function in a digital mobile device before said input data sent to distributed storages on said cloud, wherein said preprocessing function further comprising of operation of N-to-N K-muxing, converting N-inputs to N-outputs, where N is a positive integer and N>2.
