Application US20180240112

a plurality of network nodes in a network, wherein the network nodes are configured to maintain a block chain; and

a device in signal communication with one or more network nodes from the plurality of network nodes, comprising: a communication interface configured to exchange data network nodes in the network; a memory operable to store encryption keys; and a processor communicatively coupled to the communication interface and the memory, configured to implement a vault engine configured to: receive a first set of data elements; obtain an encryption key from the memory; encrypt the first set of data elements using the encryption key; embed the first set of encrypted data elements within a first block for the block chain; generate a first encrypted element map identifying the locations of the first set of encrypted data elements within the first block; combine the encryption key with the first encrypted element map to generate a creator tag; encrypt the creator tag; embed the creator tag within the first block; and publish the first block to the block chain.

receiving, by a vault engine implemented by a processor, a first set of data elements;

obtaining, by the vault engine, an encryption key from a memory;

encrypting, by the vault engine, the first set of data elements using the encryption key;

embedding, by the vault engine, the first set of encrypted data elements within a first block for the block chain;

generating, by the vault engine, an encrypted element map identifying the locations of the first set of encrypted data elements within the first block;

combining, by the vault engine, the encryption key with the encrypted element map to generate a creator tag;

encrypting, by the vault engine, the creator tag;

embedding, by the vault engine, the creator tag within the first block; and

publishing, by the vault engine, the first block to the block chain.
