Abstract: A system and computer-implemented method of grouping data records for subsequent data record searching. A level of textual similarity of data records in a group of data records is determined using matching and identifying a textual similarity metric between pairs of data records in the group of data records, and clustering the data records to form groups of textually similar data records. The groups of textually similar data records are provided to a computerised log of textually-matched data records. Further, temporally-repeating data records in the computerised log are identified. If all the data records in a group of temporally-repeating textually similar data records have a level of temporal and textual similarity above an overall similarity threshold, they are provided to a computerised log of temporally and textually-matched data records, for example for searching or future forecasting.

Abstract: System comprising an authorisation server; a client device communicably coupled to the authorisation server and configured to execute an application program; and a remote server communicably coupled to the client device for providing an application feature to the application program. The application program is configured to, in response to receiving a user request to use an application feature: access a first private key; and transmit an access request signed with the first private key to the authorisation server. The authorisation server is configured to issue a signed security token signed with a second private key to the application program in response to receiving the signed access request. The signed security token has a finite lifetime within which the application program can access the requested application feature using the signed security token. The application program is configured to access the application feature from the remote server using the signed security token.
