Multiple authority data security and access
Abstract:
Data is encrypted such that multiple keys are needed to decrypt the data. The keys are accessible to different entities so that no single entity has access to all the keys. At least one key is managed by a service provider. A customer computer system of the service provider may be configured with executable instructions directing the orchestration of communications between the various entities having access to the keys. As a result, security compromise in connection with a key does not, by itself, render the data decryptable.
