  • Method, system and program product for secure storage of content
    Patent number: 9294267
    Abstract: A method, system and program product comprise obtaining a user's username and password. A random key is generated for use as a master key. The master key is encrypted using the password to create an encrypted master key. A hash function is performed on the password to create a password hash. A random key is generated for use as a content key for encrypting the user's selected content. The content key is encrypted using the master key to create an encrypted content key. The selected content is encrypted using the content key to create encrypted content. The username, password hash, encrypted master key, first encrypted content key, and encrypted content is communicated to a server for storage in the user's account in which the possibility of decrypting at least the encrypted content by operations on the server is mitigated.
