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: 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 personal/client identification and verification process, pseudonymous system and transaction network for monitoring and restricting transactions of cryptography-based electronic money. In one embodiment, there is a legal identity-linked credential authentication protocol for providing a practical solution for issues related to cryptocurrency theft, KYC and AML, while maintaining user privacy. In other embodiments, there are mechanisms to monitor transactions for suspicious activity. A determination of AML risk and/or other risks of running afoul of financial crimes may be made, e.g., in response to a transaction, and the determination may be expressed as a risk score. In some embodiments, transactions may be held and/or reversed. In further embodiments, a client wallet within the transaction network may support multiple types of cryptocurrency and may detect transactions from or to wallets outside of the transaction network, and optionally provide an alert and/or the system may take other responsive action.
