Abstract
A method of storing a file is provided. The method includes splitting the file into a plurality of file chunks and encrypting each file chunk of the plurality of file chunks. The method also includes generating a first security key that decrypts a first encrypted file chunk of the plurality of encrypted file chunks and storing ones of the plurality of encrypted file chunks at a second location separate and distinct from the first location. The method also includes storing a second security key that decrypts a second encrypted file chunk of the plurality of file chunks at the first encrypted file chunk where access is gained to the second security key when the first encrypted file chunk is decrypted using the first security key.
