  • CLIENT-SIDE PREVENTION OF CROSS-SITE REQUEST FORGERIES
    Publication number: 20110131635
    Abstract: Cross-site request forgeries (“XSRF”) can be prevented using a client-side plugin on a client computer. The client computer accesses a content provided by a third party host via a network and generates a request to a web application as directed by the content. The client-side plugin determines whether the request is associated with suspicious activities based on the content, a source of the request and a list of approved hosts associated with the target host. In response to a determination that the request is associated with suspicious activities, the plugin removes authentication credentials from the request and sends the request to the web application.

  • UNICODE-COMPATIBLE DICTIONARY COMPRESSION
    Publication number: 20110128167
    Abstract: A character data set is compressed with a compression algorithm module of a computer system to generate one or more streams of encoded values. A code point mapper assigns the encoded values to code points reserved for private use in a Unicode format. An encoder encodes the streams of assigned encoded values using a Unicode Transformation Format (UTF). A dictionary of the compression algorithm initially includes code points assigned by the Unicode format. New entries are successively assigned to private use code points.
