  • Patent number: 10021133
    Abstract: A system and method for detecting a phishing site is disclosed. A message from a client to the site is intercepted by a security gateway. The security gateway determines if the site is a known-site or an unknown-site. If it is a known site, a reputation of the site is checked. If the site is a known-site with a bad reputation, connection between the client and the site is reset. If the site is a known-site with a good reputation, known-site testing is performed for possible phishing attack. If the site is an unknown-site, unknown-site testing for possible phishing attack is performed.

  • Patent number: 9722973
    Abstract: A method and system for a distributed anonymization system is disclosed. A master anonymization system is provided. A slave anonymization system is configured to communicate with the master anonymization system, wherein the master anonymization system permits the slave anonymization system to perform one or more functions. The slave anonymization system is configured receives a request from a user computer that requires slave anonymization system to perform a function. The performance of the function requires either storage of data to a data store in a destination computing device or retrieval of data from the data store in the destination computing device, wherein the data is stored or retrieved in an anonymized form. The slave anonymization system verifies if the function to be performed is a permitted function. If it is a permitted function, the function is performed.
