Abstract: Protection of cloud stored data from the intruders by providing shield for the cloud data before any attackers intended for attack. We here present access to data in cloud with legitimate cloud control for clients by increasing its reasonable security concerns. Security focusing on access control strategy conveys data identity established techniques for encryption. Thus, in our approach we propose coalition technique for securing data in dual way mode. It involves the procedure of encrypting the entire data of an individual in an intermediary system and then storing them in cloud database by assimilating any two individual data together. It thus, provides dual methodology for assuring security over cloud database and provide armored database. Coalition technique is the combination of dual methods that primarily encrypts the data strongly with any imposed algorithm arbitrarily chosen by the intermediary system and then that data will be merged with another encrypted data of any other individual storage in cloud and will be set flag that can only be known to the intermediary system. Coalition technique is the influential approach for securing cloud from unexpected attacks before it could happen. Our proposed approach armors the chaos of conquering security after the attack happens. Rather than securing after malfunctioning we could create an unbreakable security wall before the intrusion occurs. So, even if the attacker intrudes and extracts data they could have no beneficial data.
