Abstract

Embodiments herein provide a method for data security. A data passcode used for data encryption in electronic devices is encrypted and secret shares of the encrypted passcode are distributed to multiple entities. Recovery of the passcode and the encrypted data is performed by obtaining the secret shares from the multiple entities to reconstruct the passcode used for data encryption. FIG. 6
