System and method for detecting errors in audio data
An application programming interface (API) executed by a first processing unit combines audio data samples with error code values generated for those samples. The API then causes a data stream to be opened having sufficient bandwidth to accommodate combined samples made up of audio data samples and corresponding error code values. The combined samples are then transmitted to a decoder and validation unit within a second processing unit that receives the combined data, strips the error code values and validates the audio data based on the error code values. When the error code values indicate that the audio data has been compromised, the second processing unit terminates the output of sound derived from the audio data. |

Recovery service location for a service
A secondary location of a network acts as a recovery network for a primary location of the service. The secondary location is maintained in a warm state that is configured to replace the primary location in a case of a failover. During normal operation, the primary location actively services user load and performs backups that include full backups, incremental backups and transaction logs that are automatically replicated to the secondary location. Information is stored (e.g. time, retry count) that may be used to assist in determining when the backups are restored correctly at the secondary location. The backups are restored and the transaction logs are replayed at the secondary location to reflect changes (content and administrative) that are made to the primary location. After failover to the secondary location, the secondary location becomes the primary location and begins to actively service the user load. |

Correlating web and email attributes to detect spam
A computer correlates web and email attributes to detect spam. A security module on a client collects attributes of a web site to which an email address was submitted and attributes of an email message sent to the email address that was previously submitted. The security module analyzes the attributes of the web site and the email message to determine whether the email message was sent to the email address responsive to the submission of the email address to the web site. Based on the analysis, the security module determines whether the email message is spam. A machine learning module on a security server establishes training data describing the attributes of the web site to which email addresses were submitted and attributes of legitimate emails received in response to the address submissions. The machine learning module generates an attributes classifier for the security module for spam detection. |

Social networking system data exchange
An online publisher provides content items such as advertisements to users.

Securing application information in system-wide search engines
A system for securing application information in a shared, system-wide search service. Each application can register a security filtering module that is to be used at search time to filter data associated with that application. When a user performs a search, initial, unfiltered search results are obtained based the contents of the shared search index. The unfiltered search results are organized by application, and previously registered filter modules are called to perform user specific, per-application filtering on the initial results. The filter modules cause data to which the user issuing the search request does not have access to be removed from the search results, on a per application basis. Those of the initial search results that are determined in this way to not be accessible to the user issuing the search request are removed, resulting in a set of filtered search results that are presented to the user. The filtered search results thus contain indications only of data that is accessible to the user. In this way, the system-wide search service filters search results to remove indications of data which match the search criteria provided by the user, but to which the user does not have access, based on a conveniently extensible, per-application search result filtering process. |

By making this determination, the windowing service in effect implements information access control. This information access control helps to ensure that windowing information is not improperly passed from container to container. |

Using a tunable finite automaton for regular expression matching
Deterministic Finite Automatons (DFAs) and Nondeterministic Finite Automatons (NFAs) are two typical automatons used in the Network Intrusion Detection System (NIDS). Although they both perform regular expression matching, they have quite different performance and memory usage properties. DFAs provide fast and deterministic matching performance but suffer from the well-known state explosion problem. NFAs are compact, but their matching performance is unpredictable and with no worst case guarantee. A new automaton representation of regular expressions, called Tunable Finite Automaton (TFA), is described. TFAs resolve the DFAs' state explosion problem and the NFAs' unpredictable performance problem. Different from a DFA, which has only one active state, a TFA allows multiple concurrent active states. Thus, the total number of states required by the TFA to track the matching status is much smaller than that required by the DFA. Different from an NFA, a TFA guarantees that the number of concurrent active states is bounded by a bound factor b that can be tuned during the construction of the TFA according to the needs of the application for speed and storage. A TFA can achieve significant reductions in the number of states and memory space. |
