KBC Bank is part of KBC Group, which is one of the leading financial groups in Europe. A multi-channel bancassurance group with a geographic focus on Europe, it caters mainly for retail and private banking customers and small and medium-sized enterprises. Besides focusing on providing retail and private bancassurance services, it is also active in asset management, the provision of corporate services and market activities.

KBC occupies significant, even leading positions in its two home markets of Belgium and Central Europe and has an extensive private banking network operating under the European Private Bankers concept. It has also selectively established a presence in a number of other countries and regions around the world.

KBC Group is listed on Euronext Brussels (ticker symbol ’KBC’) and the Luxembourg Stock Exchange.

“We choose VASCO because of the impressive strong authentication package they offered,” said Kristof Browaeys, E-channel Manager at KBC Bank. “Digipass 810 has some important advantages: it brings our clients a high level of security, without any software installation at the end user’s side. To bank or shop online our clients now only need an Internet Connection, their debit card and a KBC Card Reader. Because the security technique is linked to the debit card, our clients don’t have to remember any passwords either, just their PIN code. The fact that Digipass 810 is a universal reader makes the mass deployment of the card reader a lot easier for KBC”.
“It is our pleasure to welcome a leading Belgian bank as KBC as our customer,” said Jan Valcke, VASCO’s President and COO. “The application possibilities of debit cards are growing, so we applaud KBC’s visionary approach to online banking as well as e-commerce.

AIB (Allied Irish Banks) to use VASCO’s Alphanumeric Digipass 550 and VACMAN Controller Strong Authentication for Corporate and Business Internet Banking

Leading Irish bank is first to use Alphanumeric Digipass/VACMAN Controller transaction signature; all iBB (Internet Business Banking) customers in Ireland, Northern Ireland and Great Britain to be secured with Digipass 550.

OAKBROOK TERRACE, Ill., and BRUSSELS, Belgium, January 4, 2007 - VASCO Data Security International, Inc. (NASDAQ: VDSI), (www.vasco.com ), the global number one vendor of strong user authentication products, today announced that Allied Irish Bank (www.aib.ie ) will use Digipass 550 and VACMAN Controller to secure its customers’ assets. AIB is the first financial institution to use the brand new alphanumeric Digipass. This allows the transaction signature to be generated using both numeric and alpha characters, which are commonplace in both the BIC and the IBAN.

AIB Group is Ireland’s leading banking and financial services organisation. It operates principally in Ireland, Britain, Poland and the USA. It employs more than 24,000 people worldwide in more than 750 offices.

VASCO’s Digipass 550 is a PIN protected Digipass client authentication product that provides one-time passwords, e-signatures and unique host authentication. Learn more about Digipass 550 at http://www.vasco.com/digipass-550

AIB’s corporate and business customers in Ireland and the UK will be able to perform online banking transactions in an even more secure and user friendly way. To access their accounts, customers will be able to use a Digipass-generated one-time password. To secure online payments, AIB’s customers will be able to use the brand new and extra secure alphanumeric transaction signature functionality.

Transactions will be secured using elements of the Account No. (or IBAN) and the beneficiary BIC (or Sort code), including alphanumeric characters. Based on these details, Digipass 550 will generate a transaction data signature, which the user must input for validation by the VACMAN server. The combination of Digipass generated one-time password and transaction signature offers leading edge protection against phishing and man-in-the-middle attacks.

The alphanumeric Digipass functionality is the result of key collaboration between AIB and VASCO. VASCO has developed this brand new functionality à la carte, at the request of the customer. VASCO continues to prove its claim of being the full option, all-terrain authentication company.

“Our customers’ security is of paramount importance to AIB, however the collective challenge we faced was to ensure we employed a solution which would also be in line with SEPA”, said Seán Jevens, Head of eChannel Development with AIB. “We opted for VASCO because of their track record in the financial sector and for their open and flexible approach. VASCO’s VACMAN Controller and Digipass products fully meet that description.”

“AIB is the first financial institution to offer its corporate customers alphanumeric Digipass transaction signatures,” said Jan Valcke, VASCO’s President and COO. “We developed the new Digipass alpha signing functionality in collaboration with our customer. This partnership approach is one of the strongest assets of VASCO and will lead to a more secure Internet environment for AIB’s customers.”
