Patent Issued for Reputation Based Message Analysis

July 29, 2014



By a News Reporter-Staff News Editor at Information Technology Newsweekly -- According to news reporting originating from Alexandria, Virginia, by VerticalNews journalists, a patent by the inventors Rybak, Alexander (Richboro, PA); Moor, Patrick (Menlo Park, CA); Taylor, Bradley (Menlo Park, CA), filed on April 18, 2012, was published online on July 15, 2014.

The assignee for this patent, patent number 8781093, is Google Inc. (Mountain View, CA).

Reporters obtained the following quote from the background information supplied by the inventors: "Many telecommunication consumers are subjected to a continual barrage of message traffic. Personal communication devices, such as smart phones, allow individuals to be reachable virtually anywhere and at any time by various messaging vehicles. Examples of such messages include voice telephone calls, voice messages, and text-based messaging. Sorting through such message traffic can reduce personal productivity. Unwelcomed calls or messages that add to such traffic, such as unsolicited calls (e.g., spam), are a troublesome distraction."

In addition to obtaining background information on this patent, VerticalNews editors also obtained the inventors' summary information for this patent: "Described herein are devices and techniques for detecting a communication (e.g., text message, voice call, voicemail, etc.) directed to one of a collection of subscriber IDs associated with a subscriber (e.g., telephone numbers), and selectively forwarding the message to the target subscriber's communication device or devices based on a reputation score associated with the sender/initiator of the communication. The devices and techniques described herein may be further adapted for automatically determining or otherwise updating a reputation score for the sender/initiator of the detected message, for example, in response to patterns of previously-detected calls initiated by that sender. User preferences can be provided to allow for overriding programmatically determined handling preferences, regardless of a reputation score associated with a sender/initiator of a communication.

"In some aspects, this disclosure provides a process for filtering messages. The process includes detecting an incoming message directed to a subscriber telephone number having been previously associated with at least one subscriber communications device. A sender of the incoming message is identified and a reputation score associated with the identified sender obtained. The incoming message is selectively forwarded to at least one subscriber communications device associated with the subscriber telephone number based on a reputation score associated with the identified sender. In at least some embodiments, the reputation score can be determined as a function at least in part of a number of calls made by the identified sender to telephone numbers that are unassigned to any subscriber.

"In some aspects, this disclosure provides a system for filtering inbound messages directed to a subscriber telephone number associated with at least one subscriber communications device. The system includes a call forwarding processor for detecting an inbound message from an identifiable sender and for filtering the inbound messages as a function of a reputation score associated with the identifiable sender. Also included is a scoring engine configured to compute, for the detected message originating from the identifiable sender, the reputation score associated with the identifiable sender. A data storage device is provided in communication with the call forwarding processor and the scoring engine. The data storage device is configured to store an association between the identifiable sender and at least one of the computed reputation score and message statistics for inbound messages originating from the identifiable sender. The stored reputation score associated with the identifiable sender is retrievable by the call forwarding processor.

"In some aspects, this disclosure provides a process for determining a reputation score of a message sender. The process includes detecting incoming messages received from a message sender. Each message is directed to a target subscriber identifier (ID) of a number of managed subscriber IDs of which at least some subscriber IDs are unassigned to any subscriber. For each of the incoming messages from the message sender, the process includes determining whether the target subscriber ID of the number of managed subscriber IDs is unassigned to any subscriber. A statistic associated with the message sender is evaluated. The statistic is a function of the determinations for the incoming messages from the message sender that the target subscriber ID is unassigned to any subscriber. A reputation score of the message sender is established based at least in part on the evaluated statistic.

"Several of the methods described herein can provide for the automatic determination of unwelcomed messaging sources (such as spammers), e.g., by automatic detection of incoming messages and routing of unwelcomed messages responsive to a rule. Further, several of the methods described herein can be used to adaptively customize functionality to defend against spammers or account for the possibility of false positives; for example the methods do not depend on manual black listing of message sources."
