Abstract: A method of displaying clustered data points in detail and in context within a data set, comprises the steps of: identifying one or more clustered sets of data points within a data set, said data set comprising a plurality of data points; determining a respective data range segment for the or each cluster of data points, the or each data range segment having a boundary and a scale interval; and displaying the data points in the or each segment such that each segment is mutually distinguishable. Where two or more data range segments are determined, the scale interval value for one of the data range segments is modifiable to differ from one or more of the others.

Abstract: The present invention provide a system and method for displaying on a display device (20) connectable to the system a visual representation of a physical environment, the system having display means (30) for displaying objects in the physical environment including a data management object, one or more data objects representing data sources, and one or more output objects representing means through which data from a data source can be presented to a user, a user-operated device (50) being connectable to the system to allow a user to interact with the objects. The system further comprises data receiving means (70), responsive to signals from the user-operated device (50) indicating user association of one or more data objects with the data management object, to access the data represented by the one or more associated data objects. Additionally, processing means (90) are provided for performing selected processing operations on the retrieved data, and an output means (100) is employed to pass the data processed by the processing means to a selected output object. The use of the data management object simplifies the user's interactions with and access to data, and provides a common mechanism for connecting any input data to any output objects, optionally processing that data on the way. It also provides a mechanism for performing relational database queries in a vastly simplified manner adhering to a concrete, accessible, real-world metaphor.

Abstract: A cryptographic system includes a conventional DES facility 12 for encrypting data using a key of N (=56) bits. The user 100 however need only supply a first key 30 of n bits, which is passed to a key management system 20. The key management system generates a second key of length N-n bits, which is combined with the first key to produce a full-length key 40 of N bits. This full-length key is then passed to the DES facility to allow data 16 to be encrypted and saved in a data store 14 in the conventional manner. The value of n can he controlled such that if the user forgets the first key, it can be located in a reasonable time on a simple trial and error basis, thereby allowing retrieval of the encrypted data.
