Event-Triggered Release Through Third Party of Pre-Encrypted Digital Data From Data Owner to Data Assignee

摘要

A future proof method and system for securely transferring digital data from a data owner to a data assignee through a third party involving securely registering the data owner possessing the digital data with the third party and securely predefining to the third party a trigger event associated with a data assignee, registering the data assignee with the third party, receiving encrypted digital data and an encrypted trigger event associated with the data assignee transmitted from the data owner to the third party, and securely transferring and releasing the digital data to the at least one data assignee by the third party upon validation by the third party of the occurrence of the trigger event in such a manner that digital data can be used by data assignee on data assignee system.

1. A method for securely transferring digital data from a data owner to a data assignee through a third party comprising the steps of:
a) securely registering the data owner possessing the digital data with the third party, the data owner securely predefining to the third party at least one trigger event associated with at least one data assignee; b) securely receiving from the data owner a first public key, the first public key being stored and associated with the data owner by the third party, the data owner storing and retaining access to a first private key, the third party having a second public key which is associated with the third party; c) registering the at least one data assignee with the third party; d) securely receiving from the data assignee a third public key, the third public key being stored and associated with the data assignee by the third party, the data assignee storing and retaining access to a third private key; e) sending the second public key and the third public key to the data owner; f) encrypting the digital data with the first public key and the third public key and encrypting the at least one trigger event associated with at least one data assignee with the first public key and the second public key; receiving the encrypted digital data and the encrypted at least one trigger event associated with at least one data assignee transmitted from the data owner to the third party; and g) securely transferring and releasing the digital data to the at least one data assignee by the third party upon validation by the third party of the occurrence of the at least one trigger event, the digital data being decrypted using the third private key.
