Publication number: 20210312028Abstract: Some embodiments include a messaging system capable of expression-based communication and/or expression-based actions. The messaging system can run on a computing device. For example, the messaging system monitors a camera feed from a camera of the computing device to detect a biometric signature when a messaging interface of the messaging application is actively being used. The messaging system can match the detected biometric signature against a known profile utilizing a facial recognition process to authenticate an operating user to use the messaging application. The messaging system can determine a human expression based on the detected biometric signature utilizing an expression recognition process to associate a contextual tag with an activity on the messaging interface. The messaging system can then communicate with a message server system to associate the contextual tag with content presented to the operating user or a conversation participated by the operating user via the messaging application.Type: ApplicationFiled: June 21, 2021Publication date: October 7, 2021Inventors: Eric Leuthardt, Scott Stern

Publication number: 20200279032Abstract: Some embodiments include a method of providing security and privacy for a message sender. The method can include a messaging application determining that a messaging interface of the computing device is active and is revealing or about to reveal the electronic message. The messaging application can identify a recipient account of a messaging server system that is associated with the electronic message according to the electronic message or the messaging server system. The messaging application can then monitor a data feed from a sensor of the computing device to detect a biometric pattern that matches against a biometric profile model associated with the recipient account utilizing a biometric recognition process. In response to determining that the detected biometric pattern does not match the biometric profile model associated with the recipient account, the messaging application can activate a privacy shield to prevent content of the electronic message from being revealed.Type: ApplicationFiled: March 16, 2020Publication date: September 3, 2020Inventors: Eric Leuthardt, Scott Stern
