  • Publication number: 20140089225
    Abstract: A method includes using a computer to derive a design stage directory model based on a core directory model, using the computer to derive a production stage directory model based on the core directory model, adding an extension to one of the models including an activation flag to activate the extension, and saving the models and extension to a computer readable storage device.

  • Patent number: 7581245
    Abstract: A technique for evaluating computer system passwords is disclosed. The technique commences with obtaining, for each user of a computer system, password information generated by performing a security procedure on a password entry. The technique sequentially performs, for each user name, the security procedure on sequenced entries of a dictionary until either a match with the password information is detected or the sequenced entries are exhausted. The technique adjusts the sequence of a sequenced entry in the dictionary based on the number of matches detected for the sequenced entry, so that analysis of subsequent computer system password lists more rapidly identify passwords that may present a security risk to the computer system.

  • Patent number: 7139978
    Abstract: Methods and apparatus, including computer program products, for processing a user interaction with an application, such as a browser-based application. A user interaction with the browser-based application is detected at a software framework. The browser-based application is executing in a browser at a local computer system. The user interaction is processed at the software framework, where processing includes determining whether the user interaction can be handled locally or requires access to a resource at a remote computer system. The user interaction is processed based on a result of the determination. A data item representative of the user interaction can be created at the software framework and stored at a data store. The data item can later be retrieved and the user interaction represented by the data item reprocessed at the software framework to replay the user interaction.

  • Patent number: 6847348
    Abstract: Methods, computer program products and systems are provided for executing a function of a data processing computer system. The function may relate to an object. The method may be performed by: displaying a graphical representation of an object on a display device; receiving movement data from an input device, identifying a matching movement pattern that matches the cursor movement, which corresponds to the movement data; selecting a function that relates to the matching movement pattern and the object; and executing the function for the object. The identifying step can be performed by measuring the cursor movement as changes of the cursor coordinates occur. The result may then be compared to a plurality of predefined reference movement patterns. One movement pattern may be selected out of the plurality of reference movement patterns as the matching movement pattern for the object.
