Abstract
Techniques are described for algorithmic confidential computing on personal data and to an insights provider providing access to personal data using limited-use anonymous insights records stored on a blockchain. To enable service providers and other queriers to obtain such insights information in a secure manner, an insights provider creates an anonymous insights record that is recorded on a blockchain responsive a request from a subject indicating that the subject desires to share one or more items of insights information. An anonymous insights record contains a single-use (or limited number of use) random number that is used by the insights provider to index the data in a shards index database for the relevant shards of the insights data file. These multiple segments can then be stored across multiple separate repositories using a decentralized file storage service.
