It is very challenging part to keep safely all required data that are needed in many applications for user in cloud. Storing user's data in cloud may not be fully trustworthy. Since client doesn't have copy of all stored data, he has to depend on Cloud Service Provider. But dynamic data operations, Read-Solomon and verification token construction methods don't tell user about total storage capacity of server allocated space before and after the data addition in cloud. So, the authors have to introduce a new proposed system of efficient storage measurement and space comparison algorithm with time management for measuring the total allocated storage area before and after the data insertion in cloud.
