Controlling access to datasets described in a cryptographically signed record

A method of generating a cryptographically signed record of dataset availability, the method including operations performed by a dataset validation platform, the operations comprising:

• receiving, by the dataset validation platform, first metadata about a first dataset, the first metadata indicating identification data for a source of the first dataset and an availability requirement of the first dataset, wherein the availability requirement indicates one or more criteria for use of the first dataset;
• verifying, by the dataset validation platform, the source of the first dataset, wherein verifying the source includes validating the identification data of the source;
• generating, by the dataset validation platform, a first data block including a first combination of the first metadata and validation data describing the verifying of the source;
• and
• modifying, by the dataset validation platform, the cryptographically signed record to include the first data block;
• receiving, by the dataset validation platform and from a requesting system, a request to access the first dataset, the request indicating additional identification data of the requesting system, second metadata of a second dataset, and a requested transformation based on the first dataset and the second dataset;
• verifying, by the dataset validation platform, the requesting system, wherein verifying the requesting system includes validating the additional identification data of the requesting system;
• receiving, by the dataset validation platform, a compliance verification indicating that the requested transformation is compliant with the availability requirement of the first dataset;
• responsive to receiving the compliance verification, generating, by the dataset validation platform, a second data block including a combination of the identification data of the requesting system, the second metadata, and the compliance verification;
• modifying, by the dataset validation platform, the cryptographically signed record to include the second data block;
• and
• providing, via the dataset validation platform and to the requesting system, access to the first dataset.

A system including a processing system having a processor and configured for controlling access to one or more datasets in a dataset exchange environment, the system comprising:

• a dataset validation platform capable of controlling access to one or more of the datasets in the dataset exchange environment, wherein the dataset validation platform is configured to perform operations comprising:
• receiving first metadata about a first dataset, the first metadata indicating identification data for a source of the first dataset and an availability requirement of the first dataset, wherein the availability requirement indicates one or more criteria for use of the first dataset;
• receiving, from a requesting system, a request to access the first dataset, the request indicating additional identification data of the requesting system, second metadata of a second dataset, and a requested transformation based on the first dataset and the second dataset;
• receiving a compliance alert indicating that the transformation based on the first dataset and the second dataset violates a privacy limitation of the availability requirement of the first dataset, wherein the privacy limitation indicates a level of privacy required by transformations based on, at least, the first dataset;
• responsive to the receiving the compliance alert, generating a first data block including the first metadata and a second data block including a combination of the identification data of the requesting system, the second metadata, and the compliance alert;
• modifying a cryptographically signed record to include the first data block and the second data block;
• and
• preventing access, of the requesting system, to the first dataset.
