System and method for updating a repository of images for identifying users

A system for dynamically updating a repository that includes a plurality of images of users comprising:

• a set that includes at least one camera operatively associated with a processor;
• a repository of data representative of images of a plurality of users that includes a given user;
• the processor being configured to perform repeatedly, including:
• a. obtain a plurality of images of a candidate user acquired by at least one camera of said set;
• b) comparing data representative of at least one of said acquired images with data representative of images of the plurality of users in the repository, and identifying said candidate user as the given user if the comparison meets an identification criterion;
• c) comparing data representative of at least one image that has met the identification criterion with data representative of images of the given user in the repository, and updating the data representative of images of the given user stored in the repository with data representative of at least one of the images that has met the identification criterion if the comparison has met an enrollment criterion;
• said updated repository constituting a repository for subsequent repetitions of stages (a)-(c),
• wherein said enrollment criterion includes a simulation criterion, and wherein said processor unit is configured to:
• for at least one of said acquired images that has met the identification criterion:
• comparing data representative of the acquired image with data representative of images of the given user in the repository for determining data representative of the True Accepts (TA) of the acquired image from among the images of the given user in the repository;
• and
• comparing data representative of the acquired image with data representative of images of other users in the repository for determining data representative of the False Accepts (FA) of the acquired image from among images of the other users in the repository,
• and determining whether said simulation criterion is met based on the data representative of True Accepts and data representative of False Accepts.

A method for dynamically updating a repository that includes a plurality of images of users comprising:

• providing a set that includes at least one camera operatively associated with a processor;
• providing a repository of data representative of images of a plurality of users that includes a given user;
• the method including, by the processor:
• a) obtaining a plurality of images of a candidate user acquired by at least one camera of said set;
• b) comparing data representative of at least one of said acquired images with data representative of images of the plurality of users in the repository, and identifying said candidate user as the given user if the comparison meets an identification criterion;
• c) comparing data representative of at least one image that has met the identification criterion with data representative of images of the given user in the repository, and updating the data representative of images of the given user stored in the repository with data representative of at least one of the images that has met the identification criterion if the comparison met an enrollment criterion;
• said updated repository constituting a repository for subsequent repetitions of stages (a)-(c).

• for at least one of said acquired images that has met the identification criterion:

• and
• e) comparing data representative of the acquired image with data representative of images of other users in the repository for determining data representative of the False Accepts (FA) of the acquired image from among images of the other users in the repository,
• f) and determining whether said simulation criterion is met based on the data representative of True Accepts and data representative of False Accepts.
