Data subject access request processing systems and related methods

A system comprising:

• a non-transitory computer-readable medium storing instructions;
• and
• a processing device communicatively coupled to the non-transitory computer-readable medium, wherein, the processing device is configured to execute the instructions and thereby perform operations comprising:
• receiving, via a web browser on a user device, a data subject access request associated a data subject, the data subject access request comprising a data subject access request parameter;
• accessing a consent receipt key for a transaction involving processing of personal data associated with the data subject as part of a transaction, the consent receipt key indicating consent, by the data subject, for the processing of personal data;
• accessing transaction data for the transaction on the user device, the transaction data identifying the consent receipt key;
• verifying an identity of the data subject based on receipt definitions associated with the consent receipt key and the transaction data;
• and
• in response to verifying the identity of the data subject, processing the data subject access request based on the data subject access request parameter;
• or
• preventing, based on a failure to verify the identity of the data subject, initiation of processing operations or network communication for retrieving data responsive to the data subject access request from a plurality of storage locations included in a private data network.

A non-transitory computer-readable medium storing computer-executable instructions that, when executed by processing hardware, configure the processing hardware to perform operations, comprising:

• receiving a data subject access request identifying a data subject, the data subject access request comprising a data subject access request parameter;
• accessing a consent receipt key for a transaction involving processing of personal data associated with the data subject as part of a transaction, the consent receipt key indicating consent, by the data subject, for the processing of personal data;
• accessing transaction data generated in response to initiation of the transaction;
• verifying an identity of the data subject based on receipt definitions associated with the consent receipt key and the transaction data;
• and
• in response to verifying the identity of the data subject, processing the data subject access request based on the data subject access request parameter;
• or
• preventing, based on a failure to verify the identity of the data subject, initiation of processing operations or network communication for retrieving data responsive to the data subject access request from a plurality of storage locations included in a private data network.
