Abstract:
1. A computer-implemented system for preparing content having a content type for transmission as an electronic document over a network from a content provider to a managed subscriber having a subscriber ID, comprising: a processor; a content enrichment module operative within the processor to output an enriched content that includes the content, public metadata, and private metadata, wherein the public and private metadata in the enriched content is included in accordance with a standard template associated with the content type and maintained by a trusted resource independent of the content provider; a validation engine operative within the processor to identify the content type and to compare the private metadata to the standard template associated with the content type to produce a validation signal; a key generator module operative within the processor to respond to requests with a pseudorandom number (PRN) key; an encryption module operative within the processor, in communication with the key generator module, and further operative in accordance with the validation signal to request and receive the PRN key and to encrypt the content and the private metadata using the PRN key; a transaction formatting module operative within the processor in response to any encryption by the encryption module so as to create a record that comprises the encrypted content, the encrypted private metadata, and the public metadata; a request module operative within the processor in response to creation of the record so as to request the trusted resource for an asymmetric key without transmitting the PRN key in the clear to the trusted resource and to include the asymmetric key in the record, wherein the asymmetric key is a public key asymmetric encryption of the PRN key; and a distribution module that distributes the record to the trusted resource including the encrypted content and the encrypted private metadata to which the trusted resource has no access.
