Abstract : Cloud storages like Google Drive, Firebase and Dropbox can be used for storing huge data owned by the users. Privacy has always been an issue with such technologies. The properties of security—confidentiality, integrity and availability are vital when privacy is concerned. Secret sharing schemes have been widely used for preserving the privacy of the user’s data in the following way. The data can be divided into multiple shares using secret sharing scheme, and each shares can be stored in different cloud storages. This paper puts forward a novel approach of splitting audio files into shares using ideal visual secret sharing scheme which is a lightweight approach instead of number theory-based secret sharing method. In an ideal visual secret sharing scheme, after reconstruction of the secret using secret shares, we will get back the original data without any changes. This method also makes sure that with the help of malwares an attacker cannot retrieve the information of the secret from any of the shares alone which is stored in the cloud.
