Implementation Scenarios In most institutional and government implementations, the client already has a person information system with various specialized functions, for which biometric person identity management is required. Voters, Pensioners, Employees and Other Recipients of Managed Benefits Increasingly, a need for remote person verification by biometric voice or facial identification using smart phones, is being explored by various institutions for voters, pensioners, and in National Identity Management Systems where registered persons may need to update personal information from remote locations. This requirement also comes with deployment and implementation scenarios like client-server, browser enabled web deployment, and mobile or offline operation. In the latter case, the Windows Forms version of the application restores the complete database or a subset of the database to a laptop computer. On start-up, the application will run as a client if it detects and connects to the person information server and biometric server on any connected and configured network. If there is no network connection to the person information server, the application will automatically run in Local Mode. It will run a local version of the Neurotechnology biometric engine with all server functionality, except scale and speed. In this state all inserts, updates and deletes are saved in a temporary table from which they will be replayed on the person information server when connectivity is restored. If the person information server is connected but the biometric server is unreachable, the application runs in Offline Mode. This means all biometric functions and any other functions that require biometric identification or verification are disabled. Features and Functions DigitalU has functions for: Recording and Saving common person attributes like gender, date of birth, place of birth, nationality, names, identification numbers (social security, national ID, etc.), contact information (phone, email, etc.), address, related persons, employment, and any other information required by the implementation. Only one version of date of birth, place of birth, gender and nationality can exist in DigitalU for each person. All other attributes are without limit. Each instance of an attribute for any one person is distinguishable by type, value and unique start and or end dates where applicable. Names are accumulated by name type (name at birth, married name, maiden name, alias, legal name change) and optional name date. Addresses and marital status and employment are accumulated by date and current status. These features allow the person information system to accumulate all required information throughout a subject’s lifecycle. DigitalU can store this information in its own databases or retrieve them from an existing person information system. Biometrically enrolling, identifying and verifying persons using face, fingerprint and voice. Printing ID cards for any number of categories of persons using ICAO compliant photos from the biometric system. Contact Center Functionality incorporating phone (video and voice), email, text, chat, screen sharing, WhatsApp Messaging and Microsoft Teams integration. Biometric voice identification and verification of incoming and outgoing callers on remote voice channels Performing all these functions on a central server or offline on a mobile device disconnected from the central servers. This functionality includes automated synchronization of offline data to central server when network connection is restored. DigitalU is a hybrid Windows application capable of running as a windows client connected to a database server and a biometric server on a Local Area or Wide Area Network; as a mobile application with its own portable local database, and local biometric server; and as a web application on any HTML 5 compliant web browser, over any TCP/IP network. Deployment: To fit various deployment scenarios without modification, DigitalU is fully network aware and can automatically function in all these modes solely on the basis of its admin-user defined configuration. When correctly configured for your network environment the system will automatically connect to servers on a LAN or WAN; or operate in Local mode when servers are unreachable on a network. Environmentally Responsive Operation On LAN On startup, DigitalU first pings the LAN person information database server in its configuration file. If the LAN server responds the system defaults to LAN operation. This is the mode of operation when DigitalU is run on a web server from a browser. This web scenario assumes that the web server, and person information database server are both on the same local area network or same server. On Line If the LAN Server is unreachable, DigitalU pings the webservice address in its configuration. If the web service responds, it then pings the remote biometric server address. If both are reachable. The system operates online over the Internet. Local If LAN servers and web services or remote biometric servers are unreachable, the system checks if a biometric server is running on the offline computer. If no, it starts and runs a pre-configured local biometric service on the offline computer. It then runs in local mode. This means that all biometric enrolments, verification logs, and permissible changes to the person information database are on the local databases in the offline computer. All changes are recorded for later synchronization when the offline machine next connects to the LAN server. Licensing DigitalU and all components of DigitalU, including Neurotechnology biometric server and biometric application software; SIP Server; Operating Systems (Microsoft Windows and Debian Linux); and Database Server Systems (Microsoft SQL Server and PostgreSQL), come with perpetual licenses. Data Sources and Data Access DigitalU is a multi-tiered system with a separate data access layer capable of connecting to any data source for which there are dot net framework or ODBC drivers on Microsoft Windows 10+ operating systems. DigitalU uses the following functionally distinct databases: • Person Information • Biometric Templates (face, finger and voice) • Face and Finger Images • Voice Recording • Documents • Security or Access Control • Users • Application and Database Activity Logs All databases can run on the same server or on multiple servers, depending on operational scale and security concerns. If the client already has these database functions in its information system, DigitalU can be configured to connect to them. Multiple functions can be in a single database. For scalability, resilience, maintenance and efficiency, it is recommended that biometric, image, document and log databases be separate and when necessary, migrated to their own servers. Usually, the Person Information database already exists. For example: the Civil Service Management System in Liberia; or the Pension System in NASSIT. The Biometric Templates database rarely exists and when it does, may be replaced completely. There are exceptions. In the Contract to Clean Establishment, Members and Biometric Data in NASSIT in 2019 all required databases already existed and were maintained; with the exception of the Documents database, which was created from scratch.
