Abstract: A personal/client identification and verification process, pseudonymous system and transaction network for monitoring and restricting transactions of cryptography-based electronic money. The present invention—“legal identity-linked credential authentication protocol” is a protocol providing a practical solution for the issues related to cryptocurrency theft, KYC and AML, while maintaining user privacy.

Abstract: Block chain-based multifactor personal identity verification may be provided. Verification addresses may be established on a block chain by: associating identifiers with individuals having previously verified personal identities, assigning verification addresses on a block chain to the individuals, and recording identifiers and biometric data associated with the individuals at corresponding verification addresses. Block chain-based multifactor personal identity verification using the verification addresses may be performed by: receiving one or more identifiers in connection with one or more requests to verify an identity of one or more individuals, extracting the biometric data associated with the one or more individuals from the corresponding verification addresses, and verifying the identity of the one or more individuals upon receiving matching biometric data and private keys.

Abstract: A system for providing a universal decentralized solution for verification of users with cross-verification features is described. The system may be configured to receive from a first entity, at a blockchain trust utility, information related to one or more verified first documents, the one or more verified first documents associated with a first user. The system may be configured to receive from a second entity, at the blockchain trust utility, a request for the information related to the one or more verified documents associated with the first user. The system may be configured to, upon receiving from the first user, at the blockchain trust utility, an approval of the request for the information related to the one or more verified documents associated with the first user, give access to the second entity to obtain access to information related to the one or more verified documents associated with the first user.

Abstract: Block chain/distributed ledger-based verification of entity identity or verification of a relationship between two or more entities may be provided. Verification addresses may be established on a block chain/distributed ledger by: associating identifiers and verifiers with entities having previously verified entity identities or having previously verified relationship(s) with other entities, assigning verification addresses on a block chain/distributed ledger to the entities, and recording entity identifier(s), identity verifier data and relationship verifier data associated with the entities at corresponding verification addresses. Embodiments for block chain/distributed ledger-based verification of entity identity and/or verification of entity's relationship to related entity(ies) using the verification addresses are performed using one or more identity verifiers and/or one or more relationship verifiers.

Abstract: System and methods for providing a universal decentralized solution for verification of users with cross-verification features, may be configured to receive from a first entity, at a trust utility such as a distributed database or blockchain, information related to one or more verified first document rents, the one or more verified first documents associated with a first user. The system may receive from a second entity, at the trust utility, a request for the information related to the one or more verified documents associated with the first user. The system may, upon receiving from the first user at the trust utility, an approval of the request for the information related to the one or more verified documents associated with the first user, give access to the second entity to obtain access to information related to the one or more verified documents associated with the first user.

Abstract: A secure storage system and method for storing electronic material, e.g., digital files, is disclosed. In the system and method, a digital file is broken down into file fragments and one or more fragments are stored on a distributed ledger or distributed ledgers, and the remaining (one or more) fragments are stored off the distributed ledger, e.g., on a secure server or servers, and/or on a user device or devices. The files that are stored may be biometric or partial biometric files. The files may be encrypted or hashed. The file fragments are preferably unintelligible except when decrypted and fully assembled. For example, theft or copying or hacking of one file fragment will not be effective to steal or copy intelligible, useful information. In some embodiments, the benefits of storage on a distributed ledger or distributed ledgers are combined with the benefits of storage on a secure server or servers (and/or on a user's device or devices) or both.
