Abstract: A method for compliance with Know Your Customer (KYC) and other regulations includes a pseudonymous globally unique identifier stored on a blockchain that associates a pseudonymous first party address with a globally unique identifier representing the vetted identity of the owner of the address. The method also includes a trusted third party issuing a verifiable credential for a first pseudonymous party to a proposed transaction to a second pseudonymous party to the transaction.

Abstract: The present teaching relates to method, system, medium, and implementations for authenticating a user. A first request is received to set up authentication information with respect to a user, wherein the first request specifies a type of information to be used for future authentication of the user. It is determined whether the type of information related to the user poses risks based on a reverse information search result. The type of information for being used for future authentication of the user is rejected when the type of information is determined to pose risks.

Abstract: Systems and methods for blockchain ledger growth management using separation of a blockchain ledger into multiple blockchain ledgers (each ledger having a state that can be tracked and used). The systems and methods also include linking the separated ledgers by utilizing a linking application and smart contracts added to the separated ledgers.

Abstract: Technologies for compressing a blockchain. In some examples, the technologies include removing selected blocks within a blockchain, and replacing the selected blocks with a summary block and a padding block. Each block of the selected blocks includes data in a certain state (such as data in an obsolete state). The technologies can include generating the summary block and padding blocks according to the data in the selected blocks and an original root hash included in the selected blocks and other blocks of the blockchain. The generating of the summary and padding blocks can include generating a new root hash in the summary and padding blocks that only replaces the original root hash in the summary and padding blocks. The generation of the new root hash can be based on a part of a header of a non-selected block of the blockchain directly linked to an end block of selected blocks.

Abstract: The present teaching relates to method, system, medium, and implementation for secure data management by a service provider. A request is first received for carrying out a transaction with a user and one or more data items associated with the user are then determined that need to be validated prior to the transaction. A request is then sent to the user seeking to validate the one or more data items. When a cloaked identifier is received from the user with information related to a trusted party, the cloaked identifier is then sent to the trusted party with a request for a validation response. When the validation response is received with an indication that the one or more data items are validated, the transaction with the user is carried out.

Abstract: The disclosed systems and methods provide a novel framework that leverages collected logged-in daily active users (LIDAU) data to drive network traffic to network resources, as well as engage these users to continue or remain engaged with the resources through personalization and customization according to their behaviors and patterns. LIDAU data, which is based on a raw data feed of information from network resources and an identified dataset determined from the raw data feed, is used as a basis to increase LIDAU for a specific user or a set of other users. The determined understanding of LIDAU, and its impact on users as well as the network resources the users are interacting with, enables the framework to personalize the resources that are anticipated as being visited by the users in advance of the users visiting them.

Abstract: The present teaching relates to method, system, medium, and implementation for secure data management associated with a record owner. A request is first received from a service provider for validating one or more data items in order to carry out a transaction between the record owner and the service provider. The record owner performs authentication required and send the request to a trusted party seeking to validate the one or more data items, wherein the trusted party is authorized to access the one or more data items. When a cloaked identifier to be used for validating the one or more data items is received from the trusted party, it is sent to the service provider for the service provider to use for validating the one or more data items.

Abstract: The present teaching relates to method, system, medium, and implementation for secure data management by a trusted entity. A request is first received for validating one or more data items related to a record owner in order to carry out a transaction between the record owner and a service provider. With respect to the one or more data items, at least one access limitation associated therewith is determined. A cloaked identifier is generated for the request with information related to the transaction and the one or more data items incorporated therein and sent to the record owner to proceed with the validation.

Abstract: The present teaching relates to method, system, medium, and implementations for authenticating a user. An authentication session is initiated to authenticate, via iris, a person claiming to be an authorized user. A trajectory is determined with respect to a display visible to the person. A plurality of focus dots are generated with corresponding coordinates on the trajectory with respect to the display and rendered to the person on the display in accordance with the corresponding coordinates during a specified period of time. A plurality of pictures of the iris of the person are captured during the period of time and used to determine whether the person is live based on the captured plurality of pictures of the iris of the person.

Abstract: The present teaching relates to method, system, medium, and implementation for biometric authentication in secure data management. Authentication is initiated for a person claiming to be a record owner prior to a transaction between the record owner and a service provider. Biometric based authentication of the person is performed by detecting liveness of the person and authenticating an identity of the person based on biometric information of the person. Upon successful authentication of the person, a trusted party processes a request directed to a trusted entity to validate one or more data items related to the record owner in order to proceed with the transaction and forward a cloaked identifier obtained based on the request, where the cloaked identifier is to be used by the service provider to seek a validation response with regard to the one or more data items from the trusted party.

Abstract: The present teaching relates to method, system, medium, and implementations for authenticating a user. An authentication session is initiated to authenticate, via iris, a person claiming to be an authorized user. An obfuscation configuration is retrieved with respect to the authorized user and used to determine a sub-obfuscation configuration in accordance with information associated with the authentication session. A set of expected features associated with the sub-obfuscation configuration is obtained. One or more pictures are captured from the iris of the person who is expected to carry out at least one obfuscation measure consistent with the sub-obfuscation configuration for the authorized user in accordance with the information related to the authentication session and are used to determine whether the person is live based on the set of expected features associated with the sub-obfuscation configuration.
