Abstract: At least one of a measure of trust or a measure of spoofing risk associated with a sender of a message is determined. A measure of similarity between an identifier of the sender of the message and an identifier of at least one trusted contact of a recipient of the message is determined. The measure of similarity is combined with at least one of the measure of trust or the measure of spoofing risk to at least in part determine a combined measure of risk associated with the message. Based at least in part on the combined measure of risk associated with the message, a verification action is performed including by automatically providing an inquiry message that requests a response to be provided.

Abstract: A system for detection of email risk automatically determines that a first party is considered by the system to be trusted by a second party, based on at least one of determining that the first party is on a whitelist and that the first party is in an address book associated with the second party. A message addressed to the second party from a third party is received. A risk determination of the message is performed by determining whether the message comprises a hyperlink and by determining whether a display name of the first party and a display name of third party are the same or that a domain name of the first party and a domain name of the third party are similar, wherein similarity is determined based on having a string distance below a first threshold or being conceptually similar based on a list of conceptually similar character strings.

Abstract: The ability to write illegal information or rights holder information into an immutable public ledger is problematic for society. Similarly, the inability to selectively cause funds transfers to be undone currently gives rise to significant abuses. In various embodiments, a processor, can be configured to obtain a ledger entry associated with a distributed ledger. The ledger entry can comprise an assertion authentication value and a reference. Data can be requested based on the reference. When the data is not available, an assertion can be obtained. a result can be generated and then compared. when the result and the assertion authentication value match, a challenge can be computed using a cryptographic system, wherein the challenge is based on the ledger entry. A block that incorporates the ledger entry can be broadcast to securely add the block to the distributed ledger.
