A method executed by a shared computer system that is comprised of data storage of securing content files associated with a folder data structure stored on the shared computer system, said folder data structure being associated with a public/private encryption key pair and a folder originator, said folder originator being associated with a public/private encryption key pair, the method comprising:
by a computer, receiving and storing the content file; generating a public/private encryption key pair associated with the content file; encrypting the content file with the public key associated with the content file; retrieving from data storage the public key of the public/private encryption key pair associated with the folder data structure; encrypting the private key associated with the content file using the public key of the folder data structure; encrypting the private key associated with the folder data structure using the public key associated with the folder originator associated with the folder data structure; and preventing access to an unencrypted version of the folder data structure private key and an unencrypted version of the private key associated with the content file.
