ABSTRACT:
A method of processing data from a file includes obtaining a first portion of the file, encrypting the first portion of the file to create a first encrypted portion, obtaining a second portion of the file, encrypting the second portion of the file to create a second encrypted portion, and storing the first and second encrypted portions such that each of the first and the second encrypted portions can be individually accessed. A method of processing data from a file includes receiving a request to access a first portion of the file, wherein data in the first portion of the file is encrypted, and data in a second portion of the file is encrypted, and decrypting the data in the first portion, and not the data in the second portion.
