Abstract
An imaging device includes a distributed ledger. Image files are generated by the imaging device. Data for the image files are added to a partial chain hash. When a condition is met by the data with the partial chain hash, a new block is generated for the distributed ledger using the partial chain hash and data from a block header of a previous block. The distributed ledger is used within a printing system. A printing device accessing the distributed ledger can print the images of the image files.
Claims20
A method for processing data at an imaging device using a distributed ledger, the method comprising:
- generating a first image file using the imaging device, wherein the first image file includes data;
- determining a partial chain hash of the data for the first image file;
- generating at least one additional image file having data using the imaging device;
- updating the partial chain hash with the data of the at least one additional image file;
- generating a block having a block header for a blockchain using the partial chain hash when a condition is met, wherein the image files are entries within the block;
- and
- updating the distributed ledger associated with the imaging device with the block.
A method for processing images captured by an imaging device, the method comprising:
- generating a first image file and a second image file using the imaging device, wherein the first and second image files include data;
- concatenating the data for the first and second image files;
- determining a partial chain hash of the concatenated data;
- updating the partial chain hash with data of at least one subsequent image file;
- generating a block having a block header for a blockchain using the partial chain hash when a condition is met, wherein each image file is an entry within the block;
- updating a distributed ledger with the block, wherein the imaging device and a printing device include the distributed ledger;
- and
- processing the image files at the printing device.
An imaging device comprising:
- a lens and a charged-coupled device configured to capture images;
- a processor to convert the captured images into image files having data;
- and
- a memory to store the image files, wherein the memory also stores instructions to configure the processor to
- determine a partial chain hash of the data for a first image file;
- generate at least one additional image file having data;
- update the partial chain hash with the data of the at least one additional image file;
- generate a block having a block header for a blockchain using the partial chain hash when a condition is met, wherein the image files are entries within the block;
- and
- update a distributed ledger associated with the imaging device with the block.
