  • Patent number: 11392944
    Abstract: Systems and techniques are provided for a resource transfer system. An instruction to transfer a first quantity of a resource from a first resource pool to a second resource pool may be received. A hold may be placed on a second quantity of the resource in the first resource pool. The held second quantity of the first resource may not be transferred from the first resource pool until the hold is released. Responsive to receiving a message that fulfills a condition on the hold and an instruction to execute the transfer, the hold may be released. A register that is in the first resource pool and is associated with the resource may decremented by the first quantity, and a register that is in the second resource pool and is associated with the resource may be incremented by the first quantity.

  • Patent number: 11263622
    Abstract: Computer-implemented systems and methods are detailed for establishing information on states of a machine executable contract, for instance in the context of unspent transactions (UTXOs), blockchain and deterministic finite automaton (DFA) implementation of contracts and the determination of states within those. The stages can include determining the information of interest and the codes or tags identifying that information, constructing the metadata associated with those codes or tags, combining that with a public key for an agent that will be associated with the information. The scriptPubKey values of each script may be used to provide the keys for use in constructing an external database and more specifically mapping the keys from the scriptPubKey values, linked to the information of interest. To obtain the other half of the combination, there is a derivation of the script hash addresses from the scriptPubKey values, with those being used to populate a digital wallet.

  • Patent number: 10581591
    Abstract: In certain embodiments, probabilistic secondary token issuance on a blockchain may be facilitated based on a burning of a primary token of the blockchain. In some embodiments, a blockchain transaction associated with a user may be obtained. The blockchain transaction may indicate (i) an amount of a primary token of the blockchain (owned by the user) to be burned and (ii) a secondary token of the blockchain. Based on the blockchain transaction, (i) the amount of the primary token may be burned, and (ii) a portion of a key space may be allocated to the user. Based on a determination that a hash of at least a portion of a first block of the blockchain corresponds to the key space portion allocated to the user, an issuance of an amount of the secondary token to the user may be stored on a second block for the blockchain.

  • Patent number: 9774578
    Abstract: A system includes circuitry for rewriting blockchains in a non-tamper-evident or tamper-evident operation using a key secret held in portions by multiple individually untrusted parties. The blockchains may include a series of blocks secured by integrity codes that may prevent non-tamper-evident rewrites by non-trusted parties that are not in possession of the key secret or individually-untrusted parties in possession of only a portion of the key secret. In some cases, multiple individually-untrusted parties may combine their portions into the key secret. As a group, the multiple individually-untrusted parties may perform non-tamper-evident operation with respect to at least one integrity code within the blockchain.

  • Patent number: 9621628
    Abstract: Various methods and systems are provided for capture and transmission of images to a secure repository. In one example, among others, a method includes capturing an image of a document as an image file using a mobile device, adding metadata to the image file, and securely transmitting the image file to a server. The image file can be stored in a secure repository. In another example, a mobile device includes a secure transfer application that causes the mobile device to capture an image as an image file, add metadata to the image file, and transmit the image file to a server via a secure connection. The server may store the image file in a secure repository. In another example, a non-transitory computer-readable medium includes a program that captures an image, adds metadata to the image file, and transmits the image file securely to a server.

  • Patent number: 9324087
    Abstract: In a business where a database tracks customers and manages customer accounts, a method and system correctly link accounts with customers. The method entails reading customer information for a first customer and for a second customer, and then utilizing personal identification information obtained from other sources to determine if the first customer is the same as the second customer. If the first customer and the second customer are the same person, the first customer and the second customer are identified as being the same unique person. Accounts associated with the two customers are identified as belonging to the same unique person. Viewed another way, the method and system of the present invention takes an existing database of personal identification information, and cross-references that database against other sources of personal identification information to identify persons who appear to be separate persons, but who are actually one and the same individual.

  • Patent number: 9009077
    Abstract: Metering is enabled through an arrangement in which a metering certificate is communicated to a mobile device using an over-the-air protocol. A metering trigger provides the metering certificate that includes a location to which metering data is posted by the mobile device and a public key of a public-private key pair, or alternatively provides a link to such metering certificate. A metering helper passes the metering certificate to a DRM system on the mobile device which collects metering data associated with the metering ID and uses the public key to encrypt the metering data into a metering challenge. The metering helper posts the metering challenge to the location. The metering service extracts the metering data from the metering challenge using a private key and generates a metering response that is received by the metering helper which prompts the DRM system to reset at least a portion of a data store in which the metering data is stored.

  • Patent number: 8856879
    Abstract: A backup account recovery authentication of last resort using social authentication is described. The account holder requests trustees who have been previously identified to obtain an account recovery code. The account recovery system sends a communication to the trustee for information to verify the trustee as one of the previously identified trustees. The account recovery system then may transmit a link and code with instructions for the trustee to return the link. The account recovery system then transmits a situational query to the trustee to provide additional security. Finally, if all the communications have been completed for the required level of security, the account recovery code is transmitted to the trustee. The trustee sends the account recovery code to the account holder for access to an account.

  • Patent number: 8788841
    Abstract: Techniques for representation and verification of data are disclosed. The techniques are especially useful for representation and verification of the integrity of data (integrity verification) in safe computing environments and/or systems (e.g., Trusted Computing (TC) systems and/or environments). Multiple independent representative values can be determined independently and possibly in parallel for respective portions of the data. The independent representative values can, for example, be hash values determined at the same time for respective distinct portions of the data. The integrity of the data can be determined based on the multiple hash values by, for example, processing them to determine a single hash value that can serve as an integrity value.
