Exhibit 99.1

ACTIVIDENTITY REPORTS SECOND QUARTER FISCAL 2010

FINANCIAL RESULTS

FREMONT, Calif., May 6, 2010 — ActivIdentity Corporation (NASDAQ: ACTI), a global leader in credential management and strong authentication, reported revenue for the quarter ended March 31, 2010, of $14.2 million, compared to $16.1 million for the quarter ended March 31, 2009, and $14.7 million for the quarter ended December 31, 2009.

ActivIdentity’s net loss for the quarter ended March 31, 2010, was ($4.0) million, or ($0.08) per basic and diluted share, compared to a net loss of ($2.8) million, or ($0.06) per basic and diluted share for the three months ended March 31, 2009. Net loss for the quarter ended March 31, 2010, was negatively impacted by $0.6 million in foreign exchange losses and $0.5 million write-down of auction rate securities.

ActivIdentity’s operating loss was ($3.0) million for the quarter ended March 31, 2010 compared to an operating loss of ($1.7) million for the quarter ended March 31, 2009, and ($2.9) million for the quarter ended December 31, 2009. Adjusted EBITDA was ($1.0) million for the quarter ended March 31, 2010, a decrease of $1.7 million compared to the quarter ending March 31, 2009, and an increase of $0.2 million compared to the quarter ending December 31, 2009. General and administrative expenses in the quarter ending March 31, 2010 included significant legal expenses related to intellectual property litigation. Adjusted EBITDA is a Non-GAAP measure and is defined as Operating Income (Loss) adjusted for non-recurring and non-cash items such as stock-based compensation expense, depreciation, amortization of intangibles, severance and asset impairments.

“The economic climate remains challenging and our financial results for the first two fiscal quarters reflect the softer demand that we experienced in certain markets for some of our products. We have managed our expenses exceptionally well and we believe that our fiscal 2010 will show an increase in profitability and modest growth in revenue compared to fiscal 2009,” said Grant Evans, chief executive officer and chairman of ActivIdentity. “We believe that the security and compliance market will outpace the total I.T. market growth rate over time. Our focus has been on improving our operations and sales execution and we are confident that we will see gradual improvement.”

ActivIdentity is presenting non-GAAP numbers in this press release as it believes the one-time charges for non-recurring items and the non-cash charges distort the period to period results and that investors will benefit from the comparison of information from period to period without these items. Please refer to the GAAP to non-GAAP reconciliation table for further detail. Certain financial results are subject to the application of accounting estimates, especially with regards to fair value accounting. Management has used what it believes to be appropriate valuation techniques to assess the fair value of impaired investments and the fair value of undelivered elements in multi-element software arrangements.

Supplemental Financial Measures — Adjusted EBITDA

In this press release and our related earnings conference call, we intend to provide investors with a better understanding of operating results and underlying trends to assess our performance and liquidity. We evaluate our operating performance based on several measures, including the non-GAAP financial measure of Adjusted EBITDA (defined as Operating Income adjusted for non-recurring and non-cash items such as stock-based compensation expenses, depreciation, amortization of intangibles, severance and asset impairments). We believe Adjusted EBITDA is a useful supplemental financial measure for investors because it facilitates investors’ ability to evaluate the operational strength of the company’s business. Adjusted EBITDA, however, is not calculated in accordance with GAAP and should not be considered a substitute for net income (loss) as an indicator of operating performance. A reconciliation of Adjusted EBITDA to operating income (loss) from continuing operations is presented below.

Supplemental Financial Measures — Non-GAAP Results

This press release contains non-GAAP financial measures. The following table reconciles the non-GAAP financial measures in the press release to the most directly comparable financial measures prepared in accordance with Generally Accepted Accounting Principles (GAAP). These non-GAAP measures include non-GAAP costs of revenue, operating expenses, other expenses, net loss and net loss per share amounts.

Non-GAAP financial measures should not be considered as a substitute for, or superior to, GAAP financial measures, which should be considered as the primary financial metrics for evaluating our financial performance. Significantly, non-GAAP financial measures are not based on a comprehensive set of accounting rules or principles. Instead, they are based on subjective determinations by management designed to supplement our GAAP financial measures. They are subject to a number of important limitations and should be considered only in conjunction with our consolidated financial statements prepared in accordance with GAAP. Our non-GAAP

financial measures differ from GAAP measures with the same names, may vary over time, and may differ from non-GAAP financial measures with the same or similar names used by other companies. Accordingly, investors should exercise caution when evaluating our non-GAAP financial measures.

Despite these limitations, we believe our non-GAAP financial measures provide meaningful supplemental information about our operating results, primarily because they exclude goodwill and investment impairments as well as costs and expenses that we do not believe are indicative of the ongoing operating performance of our business and our senior management. Although these items should properly be considered in our GAAP financial measures, we believe they should be excluded when evaluating our current operating performance. The non-GAAP financial measures disclosed in the accompanying press release are used by our Board of Directors and senior management to evaluate our current operating performance, are used in evaluating the performance of our senior management, and are used in our budget and planning processes. We believe that our non-GAAP financial measures are helpful to investors by facilitating comparisons of our current and prior operating results and by facilitating comparisons of our operating results with those of other software companies.

Discussion of Specific Items Excluded from Non-GAAP Financial Measures

We exclude the below items in our non-GAAP financial measures because we believe they are not closely related to the ongoing operating performance of our business and management and are generally excluded from our budget and planning process. In addition, we believe our non-GAAP financial measures are helpful to investors by facilitating comparisons of our operating results over different time periods and by facilitating comparisons of our financial performance with that of other companies. Except for costs and expenses related to restructuring and severance, these items are non-cash and do not affect cash flows.

1. Amortization of acquired intangible assets — In accordance with GAAP, we amortize intangible assets acquired in connection with acquisitions over the estimated useful lives of the assets. We exclude these amortization costs in our non-GAAP financial measures because they (i) result from prior acquisitions, rather than the ongoing operating performance of our business, and (ii) absent additional acquisitions, are expected to decline over time as the remaining carrying amounts of these assets are amortized. We believe excluding these costs helps investors compare our financial performance with that of other companies with different acquisition histories. However, as with impairment charges, we recognize that amortization costs provide a helpful measure of the financial impact and performance of prior acquisitions and investors should consider our non-GAAP financial measures in conjunction with our GAAP financial results that include amortization costs.

2. Stock-based compensation — We exclude stock-based compensation expense associated with stock options and restricted stock units granted to employees and non-executive directors in our non-GAAP financial measures. While stock based compensation is a significant component of our expenses, we believe that investors wish to be able to exclude the effects of stock based compensation expenses in comparing our financial performance with that of other companies.

3. Restructuring and severance — We exclude restructuring and severance in our non-GAAP financial measures because these costs are unrelated to our ongoing operations. We believe excluding restructuring and severance expenses help investors compare our operating performance with that of other companies. We recognize, however, that restructuring and severance will impact cash flows and that we and investors should carefully consider the impact of these costs on future cash flows.

4. Depreciation expenses — We exclude depreciation expenses in our non-GAAP financial measures because these costs are non-cash charges. Depreciation is an amortization of the original cost of a fixed asset upon acquisition.
