Abstract: A method and software product for detecting unsolicited emails, e.g. spam, involves altering the case of at least some symbols comprising an email user's email address according to a predetermined criteria prior to transmitting an email message. The altered case sequence of the email user's address is stored in a database. Subsequently, as email's are received in the email user's mailbox their intended recipient addresses are processed to determine if they include symbols whose case sequence, i.e. uppercase and lowercase, matches one of the sequences that was previously stored. If no match is found then the incoming email is treated as potentially constituting spam and is handled as such. Embodiments of the invention take advantage of a property of most Internet post office email servers being that they are generally case insensitive in respect of the symbols that make up an email address.

Abstract: A method and software product for identifying network devices having a common geographical locale. At least some of the illustrative embodiments are methods to associate a geographical location with network data including network edge address data and corresponding pivot data comprising storing network data with corresponding known geographical locations, subsequent to ascertaining new network data checking if pivot data contained therein matches pivot data of said stored network data, and if so associating the new network data with a geographical location previously associated with said matched pivot data.

Abstract: A method for passing pre-processed data to server-side applications, where a web-server platform runs a web-server application and one or more server-side applications and the web-server application interacts with said server-side applications by means of an interface separating client-side processes from server-side processes included the step of pre-processing a request from a remote client prior to data from the request being passed to the server-side applications via the interface. Additional data is generated in response to said request at the client-side of said interface. The additional data is made available to the one or more server-side applications in a format according to the interface.

Abstract: A method for a web-server host H (11) to determine the network address of a router or other network support device (10) most directly connected to a network connected computational device M such as a PC (12). In a preferred embodiment Host (11) is able to determine the geographical location of router (10), and hence the approximate geographical location of PC (12). The host may transmit information geographically relevant to PC (12) such as advertisements for locally available goods and services.
