Abstract: Some embodiments of the present invention provide a system that facilitates interactivity during automated web-site accesses. During operation, the system executes a script which automatically accesses one or more websites. While executing the script, the system retrieves user-specific data associated with a user. The system then uses the user-specific data to access a target website. While accessing the target website, the system receives an interactivity request which the system presents to the user. The system then receives a response to the interactivity request from the user, and forwards the response to the website.

Abstract: A method and system for content-based, automatic file format identification. The invention also relates to a method and system for dynamically selecting a set of bytes for byte-pattern recognition. The invention matches the pre-selected number of bytes of a file with the data signature of selected file formats. The file format information provided by the meta-data linked to the file acts as a filter that selects the file formats, which match the file information. If the attempt for file format identification, mentioned above, is unsuccessful, the invention computes the data type of the file, and subsequently identifies the corresponding text or binary file type. If a compound data type is computed, the invention identifies the file formats present in the compound file format.
