Patent number: 10979430Abstract: A computer-facilitated service receives a request from a user to access resources provided by the computer-facilitated service. In response to the request, the computer-facilitated service selects an authentication method that can be performed by a remote authentication provider. The computer-facilitated service causes the remote authentication provider to perform the authentication method. In response to an authentication decision provided by the remote authentication provider, the computer-facilitated service determines whether the user has been authenticated by the remote authentication provider. If so, the computer-facilitated service fulfills the request from the user to access the resources.Type: GrantFiled: May 17, 2017Date of Patent: April 13, 2021Assignee: Adnazon Technologies, Inc.Inventors: Daniel Wade Hitchcock, Bharath Kumar Bhimanaik

Patent number: 10880284Abstract: Disclosed are various embodiments for repurposing limited-functionality networked devices as authentication factors. In one embodiment, an authentication service identifies a limited-functionality networked device associated with an account and communicatively coupled to the network. The limited-functionality networked device is configured to perform a first function upon a predefined user interaction. The service configures the limited-functionality networked device to perform a second function based at least in part on the predefined user interaction. The service determines that the predefined user interaction has been performed by a user with respect to the limited-functionality networked device. The service authenticates the user at a client device for access to the account based at least in part on the predefined user interaction having been performed.Type: GrantFiled: August 19, 2016Date of Patent: December 29, 2020Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Daniel Wade Hitchcock, Bharath Kumar Bhimanaik, Robert Ellis Lee

Patent number: 10785201Abstract: Disclosed are various embodiments for synchronizing authentication sessions between applications. A token exchange service receives a first authentication token from a client computing device. The first authentication token corresponds to a registration of an application of the client computing device for a user account. The first authentication token is validated. A second authentication token is generated, corresponding to a browser-based session for the user account. The second authentication token is sent to the client computing device.Type: GrantFiled: April 25, 2018Date of Patent: September 22, 2020Assignee: AMAZON TECHNOLOGIES, INC.Inventor: Bharath Kumar Bhimanaik

Publication number: 20200169552Abstract: Disclosed are various embodiments for using an audio interface device to facilitate authentication for other devices. A client device presents an authentication code via an output device of the client device. The authentication code is received from a voice interface device. The voice interface device is in an authenticated state for access to an account, and the voice interface device received the authentication code from speech captured by a microphone of the voice interface device following a spoken wake word. The client device is authenticated for access to the account in response to determining that the authentication code received from the voice interface device matches the authentication code presented by the client device.Type: ApplicationFiled: January 29, 2020Publication date: May 28, 2020Inventors: SHARIQ SIDDIQUI, DANIEL WADE HITCHCOCK, BHARATH KUMAR BHIMANAIK, NATALIE NGUYEN, ANNABELLE RICHARD BACKMAN

Patent number: 10554657Abstract: Disclosed are various embodiments for using an audio interface device to facilitate authentication for other devices. An authentication service causes a first client device to present an authentication code via an output device of the first client device. The authentication service receives the authentication code from a second client device. The second client device is in an authenticated state for access to an account, and the second client device received the authentication code from an environmental sensor while in a listening mode. The authentication service authenticates the first client device for access to the account in response to determining that the authentication code received from the second client device matches the authentication code presented by the first client device.Type: GrantFiled: July 31, 2017Date of Patent: February 4, 2020Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Shariq Siddiqui, Daniel Wade Hitchcock, Bharath Kumar Bhimanaik, Natalie Nguyen, Annabelle Richard Backman

Patent number: 10440007Abstract: User input into a user interface is symbolically represented to increase security. User input received into a user interface and a mapping is applied to the user input. A result of the mapping is provided. The user interface may be updated to include the result of the mapping and/or may be provided to another device, such as over a short range communication channel. A person who views or otherwise has access to the user interface does not obtain the user input, but the result of the mapping indicates whether the user input was provided correctly.Type: GrantFiled: September 29, 2015Date of Patent: October 8, 2019Assignee: Amazon Technologies, Inc.Inventors: Harsha Ramalingam, Zachary Damen Wolfe, Darren Ernest Canavor, Brian Dang, Max Funderburk, Jesper Mikael Johansson, Bharath Kumar Bhimanaik, Jon Arron McClintock, Jason Christopher Rudmann

Patent number: 10354075Abstract: Computing devices are disclosed that include functionality for providing a trustworthy indication of software integrity. The computing devices include a hardware trust evaluation device capable of determining the trustworthiness of computer programs executing on the devices. At least one trust indicator is also connected to the hardware trust evaluation device for providing an external indication of the trustworthiness of a computer program. Additional security information regarding the trustworthiness of the computer program may be displayed on the primary display device of the computing device. The display of the security information is triggered by a user of the computing device submitting a request through a secure mechanism, where the request is unobservable and inaccessible to programs executing on the computing device. Additional secure mechanisms, such as a unique user interface for displaying the security information, can be utilized to ensure the authenticity of the displayed security information.Type: GrantFiled: June 30, 2017Date of Patent: July 16, 2019Assignee: Amazon Technologies, Inc.Inventors: Daniel Wade Hitchcock, Darren Ernest Canavor, Jesper Mikael Johansson, Bharath Kumar Bhimanaik, Andrew Jay Roths
