Cloud computing is the extended vision of computing as a effectiveness, where data owners can remotely store
their data. The essential service presents by the Cloud is Data Storage. On the other hand, it is a tricky task for sharing data
in multi-owner manner anywhere group admin and all group members can store and alter data while protecting data and
identity privacy from an untrusted cloud server, due to the frequent change of the membership. so secure multi-owner data
sharing scheme for dynamic groups in the cloud computing have been projected which absorb addition of group signature
and broadcast encryption techniques. However this system also recognized some boundaries in terms of competence and
security. since multi-owner data storing and sharing in a dynamic surroundings dumps enormous amount of data files in the
cloud, which leftovers in cloud for imprecise period of time. The confidential information stored may changed by service
providers. To maintain cloud file’s security and privacy regular elimination of unwanted files is needed. To determine this
drawback we propose new framework which is Reliable and Scalable Secure Method to Store and Share Secrete Data for
groups in Cloud i.e MONA that remove unnecessary files automatically when the predefined time period for sharing specified
by data owner has been run out which improve performance of the system in terms of security and efficiency. Also this
method decreases the overhead at the time of upload and download file in the cloud. At last proposed method by name Multi
Owner Data Sharing over Cloud (MODOC) declares required efficiency and most importantly security. We apply a working
prototype of the MODOC method and assess its performance based on the time addicted during various operations the
results give you an idea about that MODOC has the prospective to be effectively used for secure data sharing in the cloud.

We have kept IJCERT is a free peer-reviewed scientific journal to endorse conservation. We have not put up a paywall to readers, and we do not charge for publishing. But running a monthly journal costs is a lot. While we do have some associates, we still need support to keep the journal flourishing. If our readers help fund it, our future will be more secure.
