Johnny C. Liu - Fremont CA, US

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

H04L 29/06
H04L 9/32
G06F 21/00
G06F 7/04

US Classification:

713159, 713161, 713176, 713185, 726 9, 726 10, 726 20

Abstract:

An authentication mechanism for use in network-based services generates an authentication token. The authentication token is provided to a client device as part of the code comprising a content page. The content page code is received and loaded by a browser application at the client device. When the content page code is received and loaded by the browser application, the authentication token is loaded by the browser as well. Upon receiving subsequent input, the browser application may send a content request to the server. The content request includes the authentication token maintained by the browser application in the content page. A server may validate the authentication token provided in the request using version information and one or more master authentication tokens.

Assignee:

MICROSOFT CORPORATION - Redmond WA

International Classification:

H04L 9/32

US Classification:

726 9

Abstract:

Remote sign-out of web based service sessions. As a part of remote sign-out of web based service sessions, a user authentication token is accessed that is used to establish a web based service session and this user authentication token is stored in memory of an authentication server and returned in a cookie to the device. User access and deletion of the user authentication token from memory is accommodated using a device different from that which initially established the web based service session. Upon receipt of a browser request involving the user authentication token, it is determined whether the user authentication token is stored in memory. An access denial indication is provided to a web based service that indicates that the user authentication token is not stored in memory.

US Classification:

455411, 4554141

Abstract:

Techniques for providing bio signal based mobile device applications are disclosed. In some embodiments, a system for bio signal based mobile device applications includes a bio signal sensor (e.g., biosensor) or multiple biosensors (e.g., multiple biosensors for EEG detection, or multiple biosensors that can each detect different types of bio signals), a bio signal processing unit, the mobile device, and a software application(s) that utilize the bio signal information for various applications (e.g., practical applications, entertainment applications, social networking applications, and/or other applications).
