Schlumberger Provides Physical Access Security Solution to Transpetro

DeXa.Badge solution with three-factor, biometric authentication deployed in record time for stronger security

London, September 16th, 2003 — SchlumbergerSema, the information technology (IT) business segment of Schlumberger Limited, today announced it has been awarded a significant contract with Transpetro, the transportation company of Petrobras Group, the Brazilian national energy company. SchlumbergerSema has implemented its DeXa.Badge* solution to provide secure physical access to its offices in Rio de Janeiro, RJ, Brazil, ahead of schedule in only 100 days.

DeXa.Badge is a corporate identity management and access control solution that incorporates smart card and other technologies, and in this case includes biometric, three-factor authentication for even stronger security. “With the Schlumberger DeXa.Badge solution, we can increase security at our locations by better controlling the physical entrance and exits by our employees and visitors. Using biometrics, the new DeXa.Badge solution requires a fingerprint scan to confirm – identity and authorize access to certain areas of our facilities,” said José Marques, Transpetro Administration Coordinator.

Biometric authentication is the technology used to identify and authorize entry through a personal, biological feature, such as a fingerprint or an iris scan, thus ensuring the highest possible level of security in access control. The scope of the access control project at Transpetro includes physical blockade equipment, electromagnetic locking devices, biometric authentication, and physical barriers surrounding the compound. Transpetro is using fingerprint scanning to control access to highly secure areas. Due to its modular, scalable features, the DeXa.Badge solution in place can also be expanded to include other applications.

As part of its DeXa.Badge solution, SchlumbergerSema provided the cards and reader hardware, the middleware licensing and service implementation of the new system. The project was implemented in two stages, beginning with the installation of the card readers in the common areas of the building followed by installations in the private, restricted areas of Transpetro. With the DeXa.Badge access control system, event control and monitoring of the physical access environment is fully automated.

“The DeXa.Badge solution offers fast identification because the microchip on the card is a very small computer. This microprocessor allows for multiple applications to be added for expanded use in the future. Transpetro can easily add the capability to control logical access to PCs, servers and applications, such as medical benefits information, or add public key infrastructure capability for digital signatures and document encryption using the same card,” said Marcelo Camargo, SchlumbergerSema Energy Manager. “Each user is issued a corporate identity badge that grants controlled access to the building. Visitors are issued a badge with special identification to authorize temporary access. The system also allows for regular access monitoring, and immediate de-activation of access authorizations when necessary.”

DeXa.Badge is part of the Schlumberger Enterprise Security Solutions, an integrated solution approach to security including unique consulting and systems integration methodologies and tools that promise additional business value through cost reduction, reduced liability and improved earnings.
