The usage of online cloud storages via Smart phones has become popular in today’s world. This helps the people to store their huge data in to the cloud and to access it from anywhere. The individuals rely upon the Cloud Storage Providers (CSP) like Amazon, Dropbox, Google Drive, Firebase etc. for storing their information in the cloud due to the lack of storage space in their Mobile phones. The main concern in cloud storage is its privacy. To obtain privacy the Confidentiality, Integrity and Availability has to be maintained. This paper addresses about the development of a new Android application that will provide the cloud users to store the geotagged secret image in the form of shares in to various CSP and reconstruct the secret image back by combining the shares. This key idea will provide security to the stored data. Here in this paper we also propose a (1, k, n) secret image sharing scheme constructed by using (k-1, n-1) secret image sharing scheme. An image encryption scheme is also addressed as a building block which is used for mitigating the collusive attacks by CSPs. We have also implemented our apk in the scenario for distributing shares by the dealer to a group of participants within a single CSP. © 2017, Springer Nature Singapore Pte Ltd.
