  It is not an easy task to securely maintain all essential data where it has
the need in many applications for clients in cloud. To maintain our data in
cloud, it may not be fully trustworthy because client doesn't have copy of all
stored data. But any authors don't tell us data integrity through its user and
CSP level by comparison before and after the data update in cloud. So we have
to establish new proposed system for this using our data reading protocol
algorithm to check the integrity of data before and after the data insertion in
cloud. Here the security of data before and after is checked by client with the
help of CSP using our "effective automatic data reading protocol from user as
well as cloud level into the cloud" with truthfulness. Also we have proposed
the multi-server data comparison algorithm with the calculation of overall data
in each update before its outsourced level for server restore access point for
future data recovery from cloud data server. Our proposed scheme efficiently
checks integrity in efficient manner so that data integrity as well as security
can be maintained in all cases by considering drawbacks of existing methods.
