Appl. No.:

12/127014

Inventors:

David Mercer - Bothell WA, US

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 12/00

US Classification:

711118

Abstract:

Abuse of a content-sharing service is detected by an arrangement in which an in-memory cache is distributed among a plurality of nodes, such as front-end web servers, and which caches each item accessed by users of the service as a single instance in the distributed cache. Associated with each cached item is a unit of metadata which functions as a counter that is automatically incremented each time the item is served from the distributed cache. Because abusive items often tend to become quickly popular for downloading, when the counter exceeds a predetermined threshold over a given time interval, it is indicative of an access rate that makes the item a candidate for being deemed abusive. A reference to the item and its access count are responsively written to a persistent store such as a log file or database.

International Classification:

G06F 7/00

US Classification:

707640

Abstract:

The creation and utilization of network restore points is provided by a schema associated with a structured data set that can be conveniently backed up by periodically taking snapshots of the structured data to establish a series of restore points that can be used in the event that the primary structured data becomes lost or corrupted. In general, the snapshots are only taken after the structured data set has undergone a change in content, although they may be taken at other times as well. The snapshot may be taken by a network restore point engine that can be accessed by a user over the Internet. In addition, the snapshot may be stored on an Internet-based storage medium or it may be pushed to or pulled by the client so that the snapshot resides on a client-resident storage medium.

Inventors:

David Mercer - Bothell WA, US

International Classification:

G06F007/00

US Classification:

707/001000

Abstract:

The present application provides for a virtual scratch card-like system in a wireless network environment. The virtual scratch card system allows for receipt of token-based payments, the redemption of those payments, and for the exchange of token-based payments for smaller denominations of token-based payments.

International Classification:

H04M011/10

US Classification:

455/412100, 455/414100

Abstract:

The invention is directed to a method and system for managing a session of SMS messages between a service provider and a mobile device. An SMS message sent by a service provider includes a session key, such as a cookie, and the addresses for the mobile device and the service provider. An SMS gateway replaces the service provider's address in the SMS message with another address assigned to the gateway and stores the session key in a database. The modified SMS message is forwarded to the mobile device. When the mobile device replies to the modified SMS message and a timestamp has not expired, the SMS gateway replaces the other address provided by the gateway with the service provider's address and adds the session key to the modified SMS reply. The modified SMS reply and the Cookie is then forwarded to the service provider for processing.

International Classification:

US Classification:

455414100

Abstract:

Dynamic utilization of condensing metadata is enabled by condensing information being communicated to/from a mobile device. The communication exchange occurs between a mobile device and an internet service, and it involves a mobile internet service proxy. The information is condensed responsive to condensing metadata and uncondensed using the condensing metadata. In an example embodiment, condensing metadata comprises encoding metadata for tags and compression metadata for other data. In a first described implementation, a mobile internet service proxy effectuates a static installation of condensing metadata to the mobile device from the internet service. In a second described implementation, the internet service lacks condensing metadata. The mobile internet service proxy therefore retrieves the schema defining the relevant information and dynamically generates condensing metadata. This dynamically-generated metadata is copied to the mobile device so that condensed data may be communicated at least between the mobile device and the mobile internet service proxy.

Abstract:

MTOM data transfer via TCP is described. In an embodiment, a Simple Object Access Protocol (SOAP) message is separated into message units using SOAP Message Transmission Optimization Mechanism (MTOM). The message units include a text-based component and independent binary component(s) of the SOAP message. A virtual connection protocol manages and sequences binary transport connection(s), such as transmission control protocol (TCP) connection events, to provide reliable wireless transfer of the message units via the binary transport connection(s).

Abstract:

Security protocols for mobile operator networks are described. In embodiments, mobile communication link is established between a mobile phone and a media content provider via a communication service provider with which the mobile phone is registered for mobile communications, and via at least one roaming node network with which the communication service provider has a roaming service agreement. The media content provider receives a security policy request from the mobile phone to establish a security policy for end-to-end security of the mobile communication link between the media content provider and the mobile phone for data communication security. The media content provider then communicates a security policy response to the mobile phone to establish the security policy for the end-to-end security of the mobile communication link that is adaptable to security restrictions of the roaming node network.
