Secure streaming container
A system and method for securely streaming encrypted digital media content out of a digital container to a user's media player. This streaming occurs after the digital container has been delivered to the user's machine and after the user has been authorized to access the encrypted content. The user's operating system and media player treat the data stream as if it were a being delivered over the Internet (or other network) from a streaming web server. However, no Internet connection is required after the container has been delivered to the user and the data stream suffers no quality loss due to network traffic or web server access problems. In this process of the invention, the encrypted content files are decrypted and fed to the user's media player in real time and are never written to the user's hard drive or storage device. This process makes unauthorized copying of the digital content contained in the digital container virtually impossible. |

Malware detection using a white list
A reputation server is coupled to multiple clients via a network. A security module at a client identifies an application and determines whether it is on a white list. If the application is not on the white list, the security module monitors the application using a strict set of signatures. If the application is on the white list, the security module monitors the application using a relaxed set of signatures. The relaxed set of signatures can exclude legitimate characteristics possessed by the application as specified by the white list. The security module evaluates whether the application is malicious based at least in part on whether it possesses suspicious characteristics described by the signatures. The reputation server receives reports from clients identifying applications and describing characteristics possessed by the applications and uses the reports to generate the white list. |

Variable scan of files based on file context
The file context of a target file to be scanned is determined and the scan level for the file context is determined. Generally, the security risk for each file context is assessed, and the scan level appropriate for the security risk is associated with the file context. The target file is scanned at the scan level. Accordingly, a target file having a file context indicating that the file is a high security risk is scanned at a high scan level, i.e., is subject to a maximum-security scan. In this manner, high-level security is maintained. Conversely, a target file having a file context indicating that the file is a low security risk is scanned at a low scan level, i.e., is subject to a minimum-security scan or no scan at all. In this manner, high security is maintained while at the same time maximum performance is achieved. |

Data scan mechanism
Methods and devices for scanning an incoming datastream for a plurality of target patterns. The scanning system receives an incoming data stream and stores the stream as sequential symbols in a register array. Previously received symbols are shifted in the array as incoming symbols are shifted in. A trigger stage computes a hash value based on the k most recently received symbols. The trigger stage then uses the hash value to determine whether a more detailed symbol by symbol comparison is required between a group of sequential symbols stored in the array and a target pattern stored in external storage. This is done by comparing the hash value with the indices of the target patterns in the external storage. If the more detailed comparison is indicated, a full comparison stage retrieves the relevant target pattern and compares the target pattern with the sequentially stored symbols in the array. To improve the determination of whether the detailed comparison is required, a confidence stage may be placed between the trigger stage and the full comparison stage. The confidence stage computes a hashing function value based on c sequential symbols in the array with c≧k. The hashing function value is then used to determine whether the more time consuming symbol by symbol comparison is needed. |

Commitment chains for conflict resolution between disconnected data sharing applications
A sequence of processing transactions operating on a cached data set, which depend on each other because they operate on the same items of data from the data set. The transactions are saved until the master copy of the data becomes available. The transactions are played back against the master copy until one of the played back transactions fails because another transaction which operated on the same items of data but against a separate cached copy and originating from another application, was successfully played back on the master copy at an earlier time. At this point, all subsequent transactions which depended on the failing transaction are rolled back on the cached copy (with appropriate failure reports generated) and activity resumes from there. “Chained” (optimistic) transactions can therefore be applied to cached data and can be allowed to progress by recording their dependencies so they can be undone when required. |
