Explicit Minimum Storage Regenerating Codes

Abstract

in distributed storage the files are stored in set of nodes and protected by erasure-correcting codes. We cannot identify where the changes have been completed, which file has been modified.Privacy, if any files are modified, the same files will not be regenerated. It takes more time to regenerate the same file. If all files are regenerated, we will not get the same content. This solution consist unauthorized person modifies the uploaded file. End user comes to know which file will be modified that file will show failed. Failed file will be regenerating the new node, after end user will get old file and same size.
