Abstract
Systems and methods are provided for creating and using a sharable file-level key to secure data files. The sharable file-level key is generated based on a workgroup key associated with the data file, as well as unique information associated with the data file. The sharable file-level key may be used to encrypt and split data using a Secure Parser. Systems and methods are also provided for sharing data without replicating the data on the machine of the end user. Data is encrypted and split across an external/consumer network and an enterprise/producer network. Access to the data is provided using a computing image generated by a server in the enterprise/producer network and then distributed to end users of the external/consumer network. This computing image may include preloaded files that provide pointers to the data that was encrypted and split. No access or replication of the data on the enterprise/producer network is needed in order for a user of the external/consumer network to access the data.
