Photography . . . fake fingers . . . template size . . .

This is off the Canada Newswire Ltd., dated September 28, 1998:

"The delSecur system processes finger-print image data analogically, not digitally, creating an abstract image of the characteristics of the human finger. The video signal from the reader that captures the finger image is analogically processed. To register with the del-ID authentication system, you place your finger over the reader (without touching it, so you don't leave finger prints on it) and an abstract image of your finger print is stored."

I conclude this is initially photographic from the fact that it post-processes "image data" that was created "analogically." What do you take that to mean? Further, the press release also states:

"When someone claiming to be you places his finger over the reader, a new abstract image is generated and authenticated by comparison with the stored image; a comparison matrix developed by delSecur is used to determine the similarity of the two images. The matrix, patented by delSecur, comes from the field of photography . . ."

I thought that reference to "photography" might also be a tipoff.

False finger: In an October 13 press release, the company describes how a user approaches the reader, "After placing your finger over the inexpensive delSecur reader, an abstract image of the fingerprint is created." I read this as describing a "contactless" system (i.e., "over the reader" instead of "upon the reader"), but perhaps the PR was only inartfully written. All false finger systems require some contact with the surface of the reader, so measurement(s) can be taken of moisture, heat, etc. Further, very few systems presently have "false finger" safeguards, and they are exclusively, I believe, CPU-based peripherals -- which Delsecur is apparently not promoting. (The $99 Compaq reader, for instance, is not "false finger" protected, as far as I know; the CPU-based IDX F3 technology does have this, but is priced much higher.) So I made a reasonable presumption which I will stand by until Delsecur makes a claim and demonstrates this kind of capacity.

False finger detection is NOT the same as accuracy, by the way. And I'd really like to know how Delsecur managed the many thousands of independent tests (on its one mock-up device) that would demonstrate a statistically reliable accuracy claim. I wouldn't think they've had the money, or time, or equipment, to even begin such lab tests. But maybe you can provide the details of when and where and who did this testing.

Template footprint: I searched the available public databases on Delsecur, and didn't see any mention of template footprint. I'll concede this one if you can cite to a source (especially a source outside the company).

European patents are no big deal. Although they aren't issued yet, and patents are only meaningful if the technology they protect is commercially valuable.

Since you didn't dispute the rest of my earlier post, I'll assume we're in agreement on those points.
