Abstract: A method and a system for generating an identity information on a blockchain database for a user is provided. User data associated with unique userID of the user is received via user device and stored on the blockchain database. A community score is determined and continually updated based on the received corresponding user data. The updated community score is validated against a set of predefined scores in percentage, ranging from 0 to 100%. The range of predefined scores includes values pertaining to negative, neutral and positive behavior of the user. The identity information for a user is generated based on the updated community score being validated within the range of values pertaining to the positive behavior of the user.

Abstract: A system and method for secure cryptocurrency transactions with identification information includes a server arrangement communicably coupled to a distributed ledger-based platform, where the server arrangement adds information related to the transaction in the metadata of the transaction. This allows for the availability of information regarding the transaction and also track the transaction, the senders and the receivers of the transaction, if need be. Further, the system may include an additional aspect of an approving authority signing and approving a transaction based on the authenticity of the sender and receiver information, associated with the cryptocurrency transaction.

Abstract: Bioprosthetic heart valves and methods for fabricating bioprosthetic heart valves are provided. Biological tissue is attached to biocompatible material. The biocompatible material is folded to form a tubular structure with the attached biological tissue located on the inner surface of the tubular structure, the biological tissue forming leaflets of the heart valve. A stent is secured around the outer surface of the tubular structure. A region of the biocompatible material is cut. The biocompatible material is folded at the cut region away from the tissue and around the downstream edge of the stent and is secured to the stent's outer surface. The biocompatible material is folded at the upstream end of the tubular structure around the upstream edge of the stent and attached to the stent's outer surface so that the stent's inner and outer surfaces are covered with no more than a single layer of the biocompatible material.

Abstract: A method and apparatus to monitor quality of service (QoS) of wireless mobile devices is described. In one embodiment, the present invention provides a method to monitor QoS performance of one or more services provided to a mobile user. The method includes comparing the performance of at least one service provided to the mobile user against at least one QoS threshold value. In one aspect, the present invention detects and determines responses to services having performance levels that cross at least one associated QoS threshold value. In one aspect, QoS thresholds may be associated with QoS between a mobile device and network. In another aspect, QoS thresholds may be associated with the performance level of mobile device operation services such as hardware and software operations. In one embodiment, when a performance level of a service associated with a mobile device crosses at least one QoS threshold, the affected mobile device process data associated with such service performance.

Abstract: A system for increasing transaction security across existing infrastructure is provided. A user bio-metric sensor device is integrated into a credit or debit card. A display unit provides a key, preferably encrypted, upon successful utilization of the sensor device. Included in the key generation mechanism is an indicator of the transaction number or other sequential count indicative of card use. An authorization service decrypts the key in a manner at least partially dependent upon a second sequential count maintained in sync with the first count to determine whether the use is authorized. In one embodiment, a separate credit card reader may be configured to read conventional credit cards, smart cards, and credit cards incorporating such bio-metric sensor devices.
