Using file metadata for data obfuscation

摘要

A system and method may assist in securing data for transmission to a receiving entity. Received data may include metadata associated therewith. The data may be encrypted using an encryption key encoded within selected portions of the metadata, where the selection of the selected portions is based on a scheme shared with the receiving entity. The encrypted data including the metadata may be transferred to the receiving entity. The receiving entity may decrypt the encrypted data using the selected portions of the metadata.
