An identification system receives a request from a user device to identify a video captured in a video stream. The identification system identifies a display area captured in the video stream in which the video is displayed. The identification system identifies content include in the display area throughout the stream. Based on the identified content, the identification system creates a fingerprint for the video. The identification system identifies from a plurality of stored fingerprints at least one fingerprint similar to the created fingerprint. The identification system identifies video information associated with the similar fingerprint. The video information is transmitted to the user device and displayed as being video information about the video captured in the stream.

Identification of captured videos

In aspect an application may be configured to issue a request to store an object, with the request including an object reference. A delegate may be configured to receive the request to store the object, determine a hosted storage service, from among multiple hosted storage services, and a corresponding access protocol based on the object reference, and store the object in the hosted storage service using the corresponding protocol.

Manipulating objects in hosted storage

At a hosted storage service, a resource and a request to store the resource are received. The request includes a location of an access control service. The access control service is separate from the hosted storage service and controls access permissions for the resource. A request to access the stored resource is received. The hosted storage service accesses metadata stored in association with the resource and determines that access permissions for the resource are controlled by the access control service. An access request is from the hosted storage service to the access control service, the access request identifying the resource and a user of the client system.

Delegate authorization in cloud-based storage system

A hosted storage service stores a virtual data object that corresponds to data. The virtual data object includes metadata that enables access to the data in a delegated storage service but does not include the data. A delegate storage service stores the data. The hosted storage service receives a request for access to the virtual object and sends a response that includes metadata to access the data in a delegated storage service. The delegate storage service receives a request for access to the data based on the metadata. In response to receiving the request for access to the data object, the delegate storage service sends the data to the client application.

Accessing objects in hosted storage

An encrypted resource is stored in association with an access control list. A request to retrieve the resource is received. The wrapped key and the authentication credentials are sent, from the application server system, to a key server system. An unencrypted version of the resource encryption key is received from the key server system if the key server system determines that the authentication credentials correspond to a user in the group of users identified by the group identifier. The stored encrypted resource is decrypted using the received unencrypted version of the resource encryption key to generate an unencrypted version of the resource. The unencrypted version of the resource is sent, from the application server system, to the client application.

Storing encrypted objects

A hosted storage system receives a request from a requester to access a hosted resource. The hosted resource includes a binary large object. The hosted storage system providing hosted storage to a plurality of clients that are coupled to the hosted storage system. A copy of the hosted resource is created. A copy message including the copy of the hosted resource is provided to the requester. The hosted resource is maintained in the hosted storage system while the requester modifies the copy of the hosted resource. A message is received from the requester. The messages include a modified copy of the hosted resource. It is determined that the hosted resource has not been modified since the copy of the hosted resource was created. The hosted resource is replaced with the modified copy of the hosted resource.

Hosted storage locking

In one general aspect, this document describes a computer-implemented method for creating buckets in a hosted storage platform. The method may include receiving, at a hosted storage computer system that utilizes a single namespace across data stores of the hosted storage computer system, a request from a user of the hosted storage computer system to create a bucket having a name that includes a domain name. The method may also include verifying that the user is an authorized manager of a domain that corresponds to the domain name. The method may also include creating the bucket on the hosted storage computer system upon verification that the user is an authorized manager of the domain.

Domain name buckets in a hosted storage system

Profile controls for profiling a distributed application are included in messages that are also used by the distributed application to transport data. A profile initiator causes profile controls to be inserted in the header portion of a message that is being transported across a distributed system. The profile initiator may insert profile controls directly or may cause a message router that receives the message to merge profile controls into the message. The message router may receive profile controls from the profile initiator or from computer-readable media that are maintained at the message router. The message, which now includes distributed application data and profile controls, is routed to a message recipient. The message recipient accesses the message to identify profile actions that are to be performed at the message recipient. The message recipient performs at least one of the identified profile actions.

Profiling and tracing distributed applications

Lossless, context-free data compression is implemented using a data aware compression scheme that is specific to the type of data being compressed. A modified delta compression scheme is used in which difference information is encoded with reference to a set of typical difference values that commonly occur for the type of data being compressed. Selecting the compression scheme based on the type of data being compressed allows highly-compressed, yet lossless, compression. In addition, the contextual information required to uncompress information is reduced or eliminated, thereby enabling random access of the compressed data.

Lossless, context-free compression system and method

The present invention provides systems and methods for generating sets of test cases and extends to the sets of test cases and processes using the sets of test cases to develop applications. One aspect of the invention provides a data structure for efficiently storing a set of variable value combinations among which the number of variables can vary. Another aspect of the invention provides systems and methods for sequentially generating test cases to encompass a set of variable value combinations. Advantages of the invention include permitting efficient generation of near minimal sets of test cases that include specified variable value combinations, among which the number of variables can vary, and seed test cases. Sets of test cases produced by the invention are distinctive and have practical value in processes for application development. The test cases permit more efficient and thorough testing of applications, which results in better applications.
