Email filtering methods and systems
InactiveUS7072942B1Improve the level ofReduce the impactMultiple digital computer combinationsTransmissionService provisionSystem impact
Various embodiments of the invention address two critical problems that current email service providers face. First, there is the problem of maintaining high levels of customer service when email server systems are inundated with spam. Second, there is the problem of reducing the system-wide impact that spam has on the email delivery system. Current embodiments are directed to determining whether an email message is an unwanted bulk email message without necessarily considering the message that is conveyed by any portion of the email message. Through analyses of patterns of delivery of these email messages, profiles are built that allow an email server to ascertain whether there is a likelihood that any one particular email message constitutes an unwanted email message. If an email message is determined to likely constitute an unwanted email message, then memory-saving measures are implemented. In preferred embodiments, one copy of the email message is saved at a central, shared location that can be accessed by each of the intended recipients. This avoids having to replicate the email message across the system for each of the recipients.

Automatic exploration and testing of dynamic Web sites
InactiveUS7716322B2Easily plugged into systemWeb data indexingMultiple digital computer combinationsWeb siteWeb application
A unique tool, i.e., “VeriWeb”, is employed to automatically discover and systematically explore Web-site execution paths that can be followed by a user in a Web application. Unlike traditional spiders (or crawlers) that are limited to the exploration of static links, VeriWeb can navigate automatically through dynamic components of Web sites, including form submissions and execution of client-side scripts. Whenever examining a new Web page, the system determines all possible actions a user might perform—be it a link, via a button with a JavaScript handler, or via form submission—and can execute them in a systematic way. In order to systematically test different paths in a Web site, VeriWeb addresses two critical problems: systematic Web site exploration and automatically filling out forms.
