Abstract: A decentralized hybrid system for collecting, storing, and managing sensitive data, such as medical record data. Data is stored as multiple atomic records in a centralized database. A non-fungible token (NFT) is associated with each data record and assigned to a cryptographic wallet of a party owning the data in the data record on a blockchain ledger. A user key based on the wallet is stored in a centralized user database to identify the data owner to the system. Ownership tokens are granted for each data record and distributed to parties have an ownership interest in proceeds from the sale of data. When data is purchased, the proceeds are distributed, pro rata, based on the ownership tokens.

Abstract: Sonography systems and methods for performing sonography are provided in which the gender of a fetus is obfuscated. Gender is obfuscated by blurring or otherwise obfuscating the genitalia of the fetus in a sonogram, optionally also by subtly modifying features like dimensions of bones from which gender could otherwise by deduced, and by modifying sonography data so that if copied and removed from the sonography system the gender of the fetus is obfuscated in the copy. Trained neural networks are employed to locate genitalia and to correctly identify gender from features other than the genitalia so that the genitalia can be obfuscated and other features subtly modified to evade gender detection.
