Abstract
A digital asset security device, includes an asset capture unit configured to electronically capture a digital asset, a processor configured to digitally sign the captured asset, a memory configured to store a digitally signed asset from the processor, and a hashing module in communication the asset capture unit, the processor, and the memory, and configured to provide a cryptographic hash to one or more of the captured asset and the digitally signed asset.
Claims20
A digital asset ecosystem, comprising:
- an electronic processing device configured to (i) capture a digital asset at a first time of asset capture, (ii) compute a first cryptographic hash for the digital asset and for first metadata related to the digital asset at the first time of asset capture;
- (iii) digitally sign the digital asset to generate a signed asset, (iv) submit, at the first time of asset capture, a first transaction to establish provenance of the captured digital asset based on the first cryptographic hash, (v) compute a second cryptographic hash for first metadata captured with the digital asset at the first time of asset capture, (vi) rehash the signed asset with the second cryptographic hash to generate a stored asset, and (vii) submit a second transaction including the second cryptographic hash, wherein a second transaction entry includes a registration of the second transaction;
- an electronic registry configured to (i) receive the first transaction from the electronic processing device substantially at the first time of asset capture, (ii) register the first transaction on an immutable distributed digital ledger as a first transaction entry including the first cryptographic hash, and (iii) append the second transaction entry on the immutable distributed ledger;
- an electronic network configured to receive, at a second time subsequent to the first time of asset capture, a combination of the signed asset and the first cryptographic hash from the electronic processing device and distribute the combined signed asset and first cryptographic hash to an electronic media viewer of the ecosystem as registered digital content;
- and
- wherein the electronic media viewer is configured to (i) verify, with the electronic registry over the electronic network, the registered digital content as verified digital content, and (ii) enable viewing of the verified digital content,
- wherein the electronic registry is further configured to, upon distribution of the combined signed asset and first cryptographic hash by the electronic network, append a third transaction entry to the immutable distributed ledger.

An electronic device for a digital asset ecosystem including an electronic registry, an immutable distributed digital ledger, an electronic network, and an electronic media viewer, the electronic device comprising:
- an electronic capture unit configured to capture a digital asset at a first time of asset capture;
- a processor;
- and
- a memory device including computer-executable instructions therein, which, when executed by the processor, cause the processor to:
- compute a first cryptographic hash for the digital asset captured by the electronic capture unit, and for first metadata related to the digital asset at the first time of asset capture;
- digitally sign the digital asset to generate a signed asset;
- submit, at the first time of asset capture, a first transaction to establish provenance of the captured digital asset based on the first cryptographic hash;
- compute a second cryptographic hash for first metadata captured with the digital asset at the first time of asset capture;
- rehash the signed asset with the second cryptographic hash to generate a stored asset;
- and
- submit a second transaction including the second cryptographic hash,
- wherein the instructions further cause the device to enable:
- (a) the electronic registry to (i) receive the first transaction from the electronic device substantially at the first time of asset capture, (ii) register the first transaction on an immutable distributed digital ledger as a first transaction entry including the first cryptographic hash, and (iii) append a second transaction entry on the immutable distributed ledger including a registration of the second transaction;
- (b) the electronic network to receive, at a second time subsequent to the first time of asset capture, a combination of the signed asset and the first cryptographic hash from the electronic processing device and distribute the combined signed asset and first cryptographic hash to the electronic media viewer as registered digital content;
- and
- (c) the electronic media viewer to (i) verify, with the electronic registry over the electronic network, the registered digital content as verified digital content, and (ii) enable viewing of the verified digital content.
