A method of providing secure user access for doorways and network computer systems is disclosed. An overall system security level is provided. A user provides biometric information that is compared against stored biometric information of each of a plurality of users to identify the individual. When the likelihood of a match is above the likelihood necessary for identification, the threshold for that user is increased. Optionally, a threshold for another user is lowered in order to maintain a same system security level. When biometric information provided to the system is consistent, the stored template is automatically updated.

[ What is claimed is:] [1.] A method of performing one of authorising individuals and identifying individuals using a biometric security system comprising the steps of:storing a system security level;determining an initial security level for a plurality of individuals, the initial security level determined such that the actual security level of the system is at least the stored system security level;storing a current security level in association with at least one of an identification of an individual and an authorisation of an individual;performing at least one of authorising individuals and identifying individuals using the biometric security system to determine a likelihood that the individual is accurately authorised or identified;determining individuals who are consistently authorised or identified, the likelihood indicative of a higher level of security than the current security level associated with said individuals;increasing the current security level associated with the determined individuals;determining individuals who are consistently authorised or identified identified, the likelihood indicative of a lower level of security than the current security level associated with said individuals; and,lowering the current security level associated with the determined individuals such that the resulting actual system security level is at least the stored system security level.
