For Corporate America millions are lost because of lost laptops and data breaches (not to mention the reputational damage). But there are companies, such as AuthenTec (NASDAQ: AUTH), which develops security chips for devices and PCs (using fingerprint authentication), that are helping things out.

It's a growth business, and that fact can be seen with the company's Q1 report. Revenues spiked 67% to $15.5 million and gross margins jumped 3.5% to 49.6%. Basically, the company is moving its product mix to premium offerings.

More importantly, AuthenTec continues to be a major innovator in its sector, launching some new products. For example, the company has more than 60 filed and pending US patents.

AuthenTec is also seeking opportunities to purchase innovative technologies. One deal is for EzValidation, which has software for fingerprint authentication. And the price tag was only $250,000.

Going into Q2, the company expects revenues of $17.2 million to $17.8 million and non-GAAP earnings are forecast to range from $0.02 to $0.03 per share.

Based on the results, AuthenTec's shares climbed 12% to $13.50 Tuesday.

No doubt, Facebook is one of the internet's hottest startups. The company has raised gobs of venture capital, has deals with companies like Microsoft (NASDAQ: MSFT), and is often rumored to go public or be bought out.

The company's founder, Mark Zuckerberg, is just in his early twenties, fresh from Harvard. Over the past few months, several of his recent classmates have made claims that they are the real owners of the Facebook concept.

Such disputes are very common for early stage companies. And it's also common for these companies to be sloppy in protecting themselves from legal claims.

So what can be done?

AuthenTec (NASDAQ: AUTH), which develops semiconductors for fingerprint authentication, went public in late June. Since 1998, the company has shipped over 15 million of its sensors.

I had a chance to interview the company's CEO and co-founder, F. Scott Moody.

Q: "Could you provide some background on the company?"

A: "AuthenTec is a fabless mixed-signal semiconductor company and the leading provider of biometric fingerprint sensors for PC products and cell phones. We are really the first company in our specific market space to launch a successful IPO. Other companies in the general space of 'biometrics' have all focused on the government end market, specifically trying to catch the bad guy, if you will. We are the first to target the volume consumer, enterprise and commercial markets focused more on personal security, privacy and convenience, whether at home or in the office. Our focus is on small, low-cost fingerprint sensors that are integrated into laptops – where they are used primarily for security and password replacement – and into cell phones and smartphones – where they secure the device, unlock mobile payment capabilities and provide user navigation (the sensor can be used like a joystick for scrolling, menu navigation or even gaming).

Just call it the last equity blast before summer. Wall Street's equity market offers a full schedule this week, as lead managers and companies attempt to capture as much buy-side demand as possible a week before the shorter 4th of July week, which is traditionally the start of a lighter syndicate period on Wall Street.

All told, 11 IPOs and 8 Secondaries are on the docket. Those deals tentatively scheduled to price include:

IPOs:

Tuesday

• GSC Acquistion (GGA), a 15M-share IPO for this business financing company. Ladenburg, Thalman & Co. and I-Bankers Securities are the lead managers. Filing price: $10.00.
• Spectra Energy Partners LP (SEP), a 10M-share IPO for this natural gas MLP. Citigroup and Lehman Brothers are the lead managers. Filing range: $19.00-$21.00.

Semiconductor IPOs have been hit-or-miss over the years, but that's not stopping AuthenTec, which recently filed to go public.

The company develops mixed-signal semiconductors that allow for fingerprint authentication sensors. The company has shipped over 15 million sensors and is integrated in over 150 laptops, desktops and peripherals. There are even 6 million mobile phones with AuthenTec chips.

The company has more than 100 customers, including biggies like Fujitsu, Hewlett-Packard Co. (NYSE: HPQ), Hitachi Ltd. (NYSE:HIT), LG Electronics and Toshiba.

AuthenTec also has great timing. In light of recent security breaches, the company's technologies should be a big help.

And, the company is growing like a weed. Revenues increased from $19.2 million in 2005 to $33.2 million in 2006.

That should get the attention of investors.

The lead underwriter is Lehman Brothers and the proposed ticker symbol is "AUTH." You can find the filing at the SEC website.
