Encrypting information includes receiving a question/answer pair, generating a file pass phrase, encrypting the file with the file pass phrase, normalizing the answer, encrypting the file pass phrase with the normalized answer, creating a hash of the normalized answer; delivering encrypted information includes alerting the recipient of the encrypted file to be downloaded, providing the recipient with questions associated with the encrypted file, normalizing answers provided by the recipient, creating a hash of the normalized answers, comparing the hash to stored hashes associated with the encrypted file, allowing download of the encrypted file when a predetermined number of the stored hashes match the normalized hashes; and storing and triggering delivery of encrypted information to a recipient includes storing encrypted information about a recipient, determining a triggering event associated with the encrypted information, delivering to the recipient an invitation to retrieve the encrypted information upon occurrence of the triggering event. |
