Abstract: A user apparatus (1) sends, via a network (7), a request to access a computer system (3) comprising a plurality of services and a plurality of authentication levels. The system (3) negotiates with a distributed authentication provider (5) to determine a risk associated with the user request and a multi-level authentication scheme for the user. The system then redirects the user to the authentication provider for authentication according to the multi-level scheme, which may involve input by the user of one or more passwords and other identifiers including biometric identification The user is provided with access to the requested service if authentication is successful, which may be notified from the authentication provider to the system using a pre-agreed shared secret associated with the respective authentication level.

Abstract: An apparatus for managing changes to one or more files, wherein a link is associated with changes that result in an updated version of the one or more files, the apparatus comprising: a changed section determiner operable to determine which sections associated with the one or more files have changed and operable to determine metadata regarding the nature of the changes to the sections; a metrics generator operable to use the metadata to generate a first weight associated with each of the changed sections; and a mapping record generator operable to generate a mapping record for each of the changed sections, wherein a first mapping record comprises data associated with the first weight; is associated with a particular version of the one or more files; and is linked to mapping records associated with other changed sections using the link.

Abstract: Determining loading of web application pages at user interfaces, by: loading a web page comprising a set of scripting codes at a client; providing a wrapper function for an existing function in a browser including: providing a counter; monitoring for a scripting code waiting to run and incrementing the counter value for each scripting code waiting to run; monitoring for a scripting code which has executed or has started executing and decrementing the counter value for each monitored; executed scripting code; and, determining when the counter value returns to a zero count. The scripting code waiting to run may be monitored by the wrapper function around the original functions, and the execution of the scripting code may be monitored by the wrapper function around the code that the original caller wanted run.
