Abstract
An apparatus is described that comprises: communication circuitry configured to receive from a submitter, over a network, a data item being of a first data type and processing circuitry configured to: transform the first data type to a second, different, data type; remove non-significant content from the data item in the second data type; generate a hash of the data item having non-significant content removed to be signed; and provide the hash for signing.
Claims22
An apparatus comprising:
- communication circuitry configured to receive from a submitter, over a network, a data item of a first data types and
- processing circuitry configured to:
- transform the first data type to a second, different, data type;
- remove non-significant content from the data item in the second data type;
- generate a hash of the data item having non-significant content removed to be signed;
- and
- provide the hash for signing.
The apparatus according to claim 11 wherein the processing circuitry is configured to remove whitespace as the non-significant content.
