  • Publication number: 20190098350
    Abstract: Described herein is a platform for providing a resource catalog local to an appliance device, such that the appliance device is able to generate a transaction related to one or more resources within the resource catalog. In some embodiments, the appliance device may receive resource information within streaming data. For example, the appliance device may receive an indication that a portion of streaming media data is related to a resource. Upon determining that a portion of streaming data is related to a resource, the appliance device may be configured to store the portion of data in relation to the identified resource. A user may retrieve and/or execute the portion of streaming data at a later date. In some embodiments, the user may request that a transaction be conducted with respect to the resource and a corresponding transaction request may be generated by the appliance device.

  • Patent number: 10164996
    Abstract: Embodiments of the present invention are directed at methods and systems for providing a low value token buffer using only low value tokens (i.e., tokens that cannot be used to conduct transactions) within an organization to reduce access to high value tokens (i.e., tokens that are directly tied to real credentials and can be used to conduct transactions) within the organization. Accordingly, whenever a high value token is received by the organization, the high value token is changed to a low value token while being used within the organization. The low value token may be transformed to high value token upon (or before) delivery outside the organization.

  • Publication number: 20180359100
    Abstract: A method for requesting a credential associated with token in a multiple token layer environment is disclosed. A tokenization certificate serves to validate the identity of a credential requestor and provide information about the requestor's authorization for de-tokenizing a token. Also, a public key in the tokenization certificate is used to encrypt the credential for secure transmission to the requestor.

  • Publication number: 20180352005
    Abstract: Systems, devices, apparatuses, and methods of the present invention distribute authentication across multiple users. A data sensitivity model can define the sensitivity of different types of data. When an application requests access to a particular data item, the sensitivity of that data item can be determined. If the data item has a low sensitivity, access to the data item can be granted, if the data item has a high sensitivity, the system can request authentication before granting access to-the data item.

  • Publication number: 20180330342
    Abstract: Systems and methods related to cryptocurrency system that enables transactions to be performed using digital assets corresponding to an amount of fiat currency. The cryptocurrency system includes a digital asset service provider computer that can host a digital asset account on behalf of an intended recipient of a transfer (e.g., an unbanked user). In some embodiments, a transfer recipient may elect to receive the transfer in the form of a digital asset. The digital asset service provider computer may facilitate a fund transfer by a financial institution to hold currency with which the digital asset is backed. The digital asset may be generated and managed by the digital asset service provider computer as a blockchain ledger of transactions that cryptographically secures data that is stores. In some embodiments, a payment method identifier may be generated for the digital asset and utilized by the transfer recipient to perform subsequent transactions.

  • Patent number: 9978094
    Abstract: A method for providing a token revocation list is disclosed. The method includes maintaining a status for each of a plurality of tokens in a token revocation database. Token validation requests are received, and the statuses of payment tokens can be determined. Response messages with the statuses of the payment tokens are then sent to token status requesters so that they may make decisions on whether or not to use them to process transactions.

  • Publication number: 20170372417
    Abstract: Systems and methods related to a cryptocurrency system that enables transactions to be performed by transferring digital assets corresponding to amounts between appropriate entities are described. The cryptocurrency system includes a digital assets service provider computer that can host digital asset accounts associated with consumers and resource providers at which digital assets can be received. Consumers can be unbanked and use their digital asset account to perform cashless transactions. In one exemplary transaction, a consumer can receive change for the transaction as a digital asset that is assigned to their digital asset account. In another exemplary transaction, the consumer can use digital assets assigned to their digital asset account to pay for the transaction. Transfers of digital assets between accounts is managed by a ledger of transactions, which may be in the form of a block chain that cryptographically secures data that is stores.

  • Publication number: 20170270528
    Abstract: Described herein is a platform and method for determining a confidence level associated with a transaction that utilizes dynamic data. In some embodiments, the confidence level is determined based on location data received in relation to the transaction. For example, some embodiments are directed to storing first location information collected from a mobile device provided in a request for the dynamic data, receiving second location information related to a transaction conducted using the dynamic data, and comparing the two with respect to the amount of time that has elapsed between collection of each to determine a confidence level associated with a likelihood that the transaction is authentic.
