Abstract: This disclosure is related to creating and verifying a pseudonymous persona in an age verification system. The pseudonymous persona may replace showing an identification card for an age-restricted product in a transaction. A mobile application may be used to send a machine-detectable representation of numerals and characters, such as information encoded in a PDF417 barcode of the identification card, to an age verification server via a network. The age verification server may generate an unverified pseudonymous persona code based on the machine-detectable representation. Once the pseudonymous persona code is verified, the age verification server may issue a single-use token for a transaction that includes one or more age-restricted products.

Abstract: This disclosure is related to the use of a single-use token for age verification with respect to a transaction for one or more age-restricted products. A single-use token associated with a pseudonymous persona code is provided from a token database to a mobile device of a user for use in age verification in association with a transaction for one or more age-restricted products. An inputted token that is extracted from an image of a machine-readable code that is scanned by an additional device from a screen of the mobile device is received from the additional device handling the transaction. In response to determining that the inputted token matches a valid single-use token stored in the token database, a notification is sent that causes the additional device to indicate that the user is age verified with respect to the transaction for the one or more age-restricted products.

Abstract: Systems for providing high-fidelity data management for cross domain analytics may include multiple components. An access management function component may control access to data stored in a data store of a business domain by a user account associated with a search engine domain. A data management function component may select based on at least one of one or more data access privileges for the user account associated with the search engine domain or one or more privacy policies, a data view of multiple data views for viewing the data, and one or more data filters for application to the data. An external API manager component may store in the data store of the business domain cross correlation information that correlates a plurality of machine learning model identifiers of machine learning models of the search engine domain with one or more corresponding business APIs of the business domain.
