Abstract: An initial risk of an electronic message is determined. Based on the initial risk, it is determined whether to modify the electronic message. In an event it is determined to modify the electronic message: the electronic message is modified; the modified electronic message is allowed to be delivered to an intended recipient of the electronic message; a secondary computer security risk assessment of the electronic message is automatically performed; and based on the secondary computer security risk assessment, the modified message is updated.

Abstract: A received message sent from a first message account to a second message account is received. A security risk associated with the received message is determined. It is determined that the security risk associated with the received message meets one or more criteria. Based on the determination that the security risk associated with the received message meets the one or more criteria, a responsive message in response to the received message is automatically generated and sent. An interaction with the responsive message is analyzed. Based on a result of the analysis of the interaction with the responsive message, a security risk associated with the first message account is classified.

Abstract: Disclosed is a method and apparatus for performing steps to cause encoded information to be stored at a client device during a first network session between a server and the client device. To cause encoded information to be stored at a client device, the server first determines a set of network resource requests that encode the information. These network resource requests may include requests for one or more specific URLs and/or requests for one or more files. The server then causes the client device to initiate the network resource requests. The server may cause this initiation by, for example, redirecting the client device to the network resources. The client device initiating the network resource requests causes data representative of the network resource requests to be stored at the client device.

Abstract: Rapid verification of executing processes includes receiving a seed from a verification unit. A checksum is generated at least in part by using a processor. The processor is coupled to a hierarchical memory, the hierarchical memory comprising an instruction cache, a data cache, and a shared memory accessible by both the instruction cache and the data cache. The shared memory is configured to store an executing program. A size of at least one of the instruction cache and the data cache is insufficient to store the entire executing program. The checksum is transmitted to the verification unit.

Abstract: Systems and methods as provided herein may create a biometric model associated with a user. The created biometric model may be used to generate challenges that are presented to the user for authentication purposes. A user response to the challenge may be compared to an expected response, and if the user response matches within a predetermined error of the expected response, the user may be authenticated. The systems and methods may further generate challenges that are adaptively designed to address weaknesses or errors in the created model such that the model is more closely associated with a user and the user is more likely to be the only person capable of successfully responding to the generated challenges.

Abstract: One embodiment includes a method that recovers information on one or more characteristics of a node, wherein the information corresponds to at least one selected from the group consisting of: hardware, software, event history, and functionalities. The method derives one or more characterizations of the node based on the information. The characterizations reflect a current state of a characteristic of the one or more characteristics. Characterizations are expressed as statements on a blockchain. The method recovers, from an assertion unit, an assertion verifying validity of the characterizations. The method derives a reputation score for the assertion unit, wherein the reputation score discloses estimates of verification accuracy for the assertion unit. The method determines a risk score for the node based on the reputation score, the characterizations, and the assertion, wherein the risk score corresponds to a degree of risk associated with transacting with the node.

The partitions can have different access and/or use rights with respect to the digital assets stored in their respective addresses.

Abstract: A method of classifying electronic communications includes receiving an electronic message. A whitelist is input comprising at least one entry associated with an authoritative entity. At least one similarity score is computed based on an extent to which the message matches the entry in the whitelist. When the similarity score exceeds that threshold value, an indicator is output of a risk that the message appears to be associated with the authoritative entity. It is determined whether the message was sent from the authoritative entity based on at least one of attempting to verify an email authentication, and comparing an email address of a sender of the message to an email address associated with the authoritative entity. Responsive to determining that the message was sent from the authoritative entity, the message is delivered. Responsive to determining that the message was not sent from the authoritative entity, a security action is performed.
