Patent number: 9779236Abstract: One or more techniques and/or systems are provided for risk assessment. Historical authentication data and/or compromised user account data may be evaluated to identify a set of authentication context properties associated with user authentication sessions and/or a set of malicious account context properties associated with compromised user accounts (e.g., properties indicative of whether a user recently visited a malicious site, created a fake social network profile, logged in from unknown locations, etc.). The set of authentication context properties and/or the set of malicious account context properties may be annotated to create an annotated context property training set that may be used to train a risk assessment machine learning model to generate a risk assessment model. The risk assessment model may be used to evaluate user context properties of a user account event to generate a risk analysis metric indicative of a likelihood the user account event is malicious or safe.Type: GrantFiled: June 21, 2016Date of Patent: October 3, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Luke Abrams, David J. Steeves, Robert Alexander Sim, Pui-Yin Winfred Wong, Harry Simon Katz, Aaron Small, Dana Scott Kaufman, Adrian Kreuziger, Mark A. Nikiel, Laurentiu Bogdan Cristofor, Alexa Lynn Keizur, Collin Tibbetts, Charles Hayden

Patent number: 7921173Abstract: The present invention provides for generating inputs that can be provided to a message classification module to facilitate more reliable classification of electronic messages, such as, for example, as unwanted and/or unsolicited. In one embodiment, a sending messaging server provides an appropriate response to address verification data thereby indicating a reduced likelihood of the sending messaging server using a forged network address. In another embodiment, it is determined if a messaging server is authorized to send electronic messages for a domain. In yet another embodiment, electronic message transmission policies adhered to by a domain are identified. In yet a further embodiment, a sending computer system expends computational resources to solve a computational puzzle and includes an answer document in an electronic message. A receiving computer system receives the electronic message and verifies the answer document.Type: GrantFiled: April 7, 2009Date of Patent: April 5, 2011Assignee: Microsoft CorporationInventors: Robert George Atkinson, Joshua T. Goodman, James M. Lyon, Roy Williams, Khaja E. Ahmed, Harry Simon Katz, Robert L. Rounthwaite, Andrew V. Goldberg, Cynthia Dwork
