A user can request provisioning of account information for an account to a plurality of resource providing entities. The account may be a new or existing account issued by an authorization computer. The authorization computer may prompt the user to select one or more resource providing entities to which to provision a token associated with the account. Processor server computer may then tokenize the account information associated with the account by determining a token for each resource providing entity selected by the user. In some cases, a token may be provisioned to an already existing account or profile (e.g., account on file) associated with a resource providing entity. In other cases, an account or profile associated with a resource providing entity may not yet exist and thus may be created before a token may be provisioned. Subsequently, the user may utilize provisioned tokens to conduct transactions.

Instant token issuance

Embodiments of the invention are directed to a method for reducing a computational burden of a blockchain provider. A data processing computer may facilitate an exchange of a data transfer message between respective applications of a first and second device. The data processing computer may maintain an electronic record according to the exchange. A net transfer value may be determined for the record and data comprising the net transfer value may be transmitted to a blockchain provider. Receipt of the data by the blockchain provider may cause the blockchain provider to update a ledger with the net transfer value.

Techniques for secure blockchain management

Embodiments are directed to a method for securely performing biometric authentication online. The method described can be used to securely perform biometric authentication on a mobile device. For protecting the privacy of the users biometric data, a cryptographic comparison protocol can be used to perform matching of encrypted templates. For example, the cryptographic comparison protocol may involve Fuzzy Extractors (FE), Homomorphic Encryption (HE), and/or Secure Multi-Party Computation (SMPC).

Use of biometrics and privacy preserving methods to authenticate account holders online

Described herein are systems and methods in which resource-related content is provided to a number of mobile devices. In some embodiments, as a content provider streams a media presentation or a live real-world event occurs, it may also provide an indication of a resource to a content distribution hub. Upon receiving that indication of the resource, the content distribution hub may identify and/or generate resource-related content relevant to the indicated resource. The resource-related content may then be distributed to a number of subscriber devices according to subscription data maintained by the content distribution hub. In some embodiments, the content hub is also configured to initiate transactions related to the resources.
