Apparatus, computer program and method
An apparatus is described. The apparatus comprises: communication circuitry configured to receive from a submitter, over a network, a data item of a first data type, wherein the data item comprises a plurality of components and the apparatus further comprises: processing circuitry configured to: sequentially receive the plurality of components of the data item and for each component in succession in the sequence, the processing circuitry is configured to: remove non-significant content from the component of the data item; generate a data item of a second data type from the sequentially received plurality of components; generate a hash of the generated data item; and provide the hash for signing.
1. An apparatus comprising:
communication circuitry configured to receive from a submitter, over a network, a data item of a first data type, wherein the data item comprises a plurality of components; and
processing circuitry configured to:
sequentially receive the plurality of components of the data item;
for each component in succession in the sequence:
sequentially map each data field of the first data type to a corresponding field of a second data type, wherein the first data type is different than the second data type; and then
remove non-significant content from the component of the data item;
generate a data item of the second data type from the sequentially received plurality of components having non-significant content removed;
generate a hash of the generated data item; and
provide the hash for signing.
2. The apparatus according to claim 1 , wherein each component is a data field within the data item.
3. A method comprising:
receiving from a submitter, over a network, a data item of a first data type, wherein the data item comprises a plurality of components;
sequentially receiving the plurality of components of the data item;
for each component in succession in the sequence:
sequentially mapping each data field of the first data type to a corresponding data field of the second data type, wherein the first data type is different than the second data type; and then
removing non-significant content from the component of the data item;
generating a data item of the second data type from the sequentially received plurality of components having non-significant content removed;
generating a hash of the generated data item; and
providing the hash for signing.
4. The method according to claim 3 , wherein each component is a data field within the data item.
5. A non-transitory computer-readable storage medium comprising executable instructions, which when executed by at least one processor, cause the at least one processor to:
receive from a submitter, over a network, a data item of a first data type, wherein the data item comprises a plurality of components;
sequentially receive the plurality of components of the data item;
for each component in succession in the sequence:
sequentially map each data field of the first data type to a corresponding data field of the second data type, wherein the first data type is different than the second data type; and then
remove non-significant content from the component of the data item;
generate a data item of the second data type from the sequentially received plurality of components having non-significant content removed;
generate a hash of the generated data item; and
provide the hash for signing.
6. The non-transitory computer-readable storage medium according to claim 5 , wherein each component is a data field within the data item.
