  • Patent number: 8621638
    Abstract: Methods and systems for operation upon one or more data processors for biasing a reputation score. A communication having data that identifies a plurality of biasing characteristics related to a messaging entity associated with the communication is received. The identified plurality of biasing characteristics related to the messaging entity associated with the communication based upon a plurality of criteria are analyzed, and a reputation score associated with the messaging entity is biased based upon the analysis of the identified plurality of biasing characteristics related to the messaging entity associated with the communication.

  • Patent number: 8132250
    Abstract: Methods and systems for operation upon one or more data processors that classify communications from messaging entities. A method can include receiving a communication that was sent from a messaging entity. A plurality of message classification techniques is used to classify the communication. Each message classification technique is associated with a confidence value which is used in generating a message classification output from the message classification technique. The message classification outputs are combined in order to generate a message profile score. The message profile score is used in deciding what action is to be taken with respect to the communication associated with the messaging entity.

  • Patent number: 7779466
    Abstract: The present invention is directed to systems and methods for enhancing electronic communication security. A communication transmitted over a communications network is received and tested by a collection engine to generate data associated with the received communication. An analysis engine analyzes the data generated by the collection engine along with data associated with previously received communications to whether an anomaly exists. If an anomaly exists with respect to the received communication, an action engine initiates a predetermined response.

  • Patent number: 7694128
    Abstract: Systems and methods for secure delivery of electronic communications are provided. A communication transmitted over a communications network is received by a system processor. The system processor selects a secure delivery mechanism for delivering the communication. The system processor attempts to deliver the communication to the predetermined recipient via the selected secure delivery mechanism. Some systems can further provide for determining whether a particular received communication requires secure delivery.

  • Patent number: 7519994
    Abstract: The present invention is directed to systems and methods for enhancing electronic communication security. An electronic communication is received and stored. A plurality of risk assessments are made with respect to the received communication thereby generating a risk profile associated with the communication. The assessments are made in a sequential manner by assigning the stored communication and index and serially placing the index on queue associated with interrogation engines that perform the various assessments. The index is initially placed in a queue associated with an interrogation engine performing the first type of assessment on the communication. The index is placed in a subsequent queue only after the interrogation engine associated with the prior queue in which the index was placed has assessed the communication. This is repeated until all desired assessments have been performed.

  • Patent number: 7458098
    Abstract: The present invention is directed to systems and methods for enhancing electronic communication security. An electronic communication related to an application is received and stored. One or more risk assessments are made with respect to the received communication thereby generating a risk profile associated with the communication. The risk profile is analyzed with respect to data associated with previously received communications to determine if the received communication is anomalous. If the received communication is determined to be anomalous, an anomaly indicator signal is output.

  • Publication number: 20030172291
    Abstract: The present invention is directed to systems and methods for detecting and preventing the delivery of unsolicited communications. A communication transmitted over a communications network is received and analyzed by a system processor. The system processor can extract attributes from the communication and compare extracted attributes to information stored in a system data store. In processing the communication, the system processor may assign a confidence level, a trust level, or other indicia of content. The results of that processing, analysis, and comparison can be used to direct the further handling of the communication. The system processor can dispose of communications by quarantining, deleting, or forwarding.
