  • Publication number: 20190288832
    Abstract: A method of for improving performance scalability of an application blockchain system in which application data are organized according to accounts, and changes in application data are caused by account transactions. A composite blockchain system comprises 2 types of subsystem blockchains: an ABC (account blockchain) type stores detailed account data for a set of accounts, and a TBC (transaction blockchain) type stores data necessary to perform account transactions for a set of accounts. A TBC chain writes account data into an ABC chain, and a TBC chain reads account data from an ABC chain.

  • Publication number: 20190258610
    Abstract: A method of adding a new block to a blockchain system with a plurality of system nodes, with the purpose of recording a set of submitted transactions in the face of Byzantine faults, based on data consistency among the system nodes. Upon receiving a set of submitted transactions (this set of transactions to be recorded in a new block in the blockchain), each system node generates a digital representation of the set of submitted transactions. The digital representations at the system nodes are made consistent among the system nodes, thereby a submitted transaction is determined to be included in the new block based on the synchronized digital representations at the system nodes.

  • Patent number: 10210525
    Abstract: A method and system to digitize printed information on a business card and to link the digitized data to a social networking service, referred to as a Meeting-Spot (or simply an MSP) service, employs quick response codes (QRCs) to uniquely identify business cards printed with a QRC. An online MSP service offers a free MSP app, which is installable on mobile devices. The MSP service will offer a plurality of MSP business cards to its members. A QRC image is printed on at least one side of an MSP business card. Further, the data encoded in the QRC on an MSP business card comprise at least an identifier to uniquely identify a business card. The identifier encoded in the QRC printed on an MSP business card may be a UUID (universal unique identifier), which complies with the identifier standard set by the Open Software Foundation (OSF). Optionally, the identifier is replaced by a proprietary hash code that can uniquely identify a business card.

  • Patent number: 10057534
    Abstract: A hybrid modular appliance or electronic device allows a user to plug a number of snap-together component modules of different types into a base device, so that the resulting assembly performs a custom-designed functionality. With no attached component modules, the base device functions as a standalone consumer or office appliance. At least one component module has its functionality not supporting the functionality of the base device, thereby allowing the resulting assembly a hybrid device. Examples of the hybrid modular devices include a TV-Wi-Fi-router, and a TV-storage-DVR-Wi-Fi-router. A hybrid modular device can serve as a videoconference device, a music jukebox, or a home theater unit.

  • Publication number: 20180183809
    Abstract: A system and method enables secure login at linked sites with a universal ID (UID) and possibly different or same password to linked identities. In such logins, a user stays at the linked login page, and the login name and password are sent to a UID provider for authentication. A UID provider may perform optional multi-factored authentication. A UID user is able to manage all his accounts, which are linked to his UID service, by changing the login names, passwords, security requirements, privacy requirements, and authentication requirements, with group-wise control. Successful or failed logins to linked accounts may be reported to a UID user. A UID user may disable logins at a group of linked accounts.

  • Publication number: 20180137549
    Abstract: A system and method is provided for non-repudiated evidence that a copied digital item received by a buyer is sent by a specific and authorized distributor, and the copy is uncorrupted and legitimate for sale by the distributor. Non-repudiated evidence is generated based on unique encryption keys and hash codes identifying a specific distributor and a specific digital item. Credential checking is performed by a distribution system operator which is also responsible for collecting funds directly or indirectly. A potential buyer of a digital item is enabled to produce a digital object to send to the system operator to authenticate a received digital item. By checking the distributor's credential, the system operator authenticates the distributor and sends back a transaction ID and an encryption key. Once the buyer has purchased the digital item, the buyer can then be authorized to be a distributor of the digital item.

  • Publication number: 20180005210
    Abstract: A system and methods expedite and make secure payment data entry, and payment and authorization and authorization, for both in-store and online purchases. A mobile app, or widget or browser extension or installed service, on a mobile communication device, generates a barcode to be scanned at a point-of-sale terminal. Optional confirmation is sent to an app, or browser extension or widget or installed service, on a mobile or fixed communication device, to confirm a purchase. An independent app, or browser extension or widget or installed service, on a mobile or fixed communication device, generates a barcode that is sent directly to an online point-of-sale system. The method allows a purchaser to use the same app, or widget or browser extension or installed service, to purchase from any retailer with installed collaborating software.

  • Patent number: 9420057
    Abstract: A system and method, called federated cache network (FCN), places and optimizes content caches located in an access or backhaul network of a network service provider or multiple system operator. A FCN comprises a trunk cache and a plurality of branch caches and leaf caches. In a mobile carrier network, the mobility management entity (MME) informs a TCP termination device that a mobile device is moving toward a new base station. The live and terminated TCP sessions associated with a mobile terminal that is moving to a new base station are copied and re-terminated at the new base station, in anticipation of a possible handoff.
