Innovative Fingerprint Solutions Reduce Storage Needs and Boost Security

New technology for matching fingerprints for security purposes is proving about as reliable but much more efficient than traditional techniques, according to a new study by the National Institute of Standards and Technology. NIST studied the use of "minutiae templates," which are mathematical representations of full-blown fingerprint images that are seen as being much easier for vendors of biometric security systems to exchange with each other. The study involved use of a new standard for minutiae data that makes data exchange simpler than when proprietary techniques for converting fingerprint images to minutiae data. . The templates are also a fraction of the size of a fingerprint image, reducing the need for storage on smart cards and other such devices. Fourteen vendors of fingerprint technologies participated in the Minutiae Interoperability Exchange Test (MINEX), which was sponsored by the U.S. Department of Homeland Security and the Department of Justice. The standards group said that performance depended on how many fingerprints from a person were being matched, with systems using two index fingers accurate more than 98% of the time. The link for this article located at Network World is no longer available. .

I was reading through a bioinformatics book the other day, and was reminded of a useful shortcut for comparing a text against various corpora. A number of researchers have simply fed DNA sequence data into the popular Ziv-Lempel compression algorithm, to see how much redundancy it contains. Loosely speaking, the LZ (Zip) and the related gzip compression algorithms look for repeated strings within a text, and replace each repeat with a reference to the first occurrence. The compression ratio achieved therefore measures how many repeated fragments, words or phrases occur in the text. A related technique allows us to measure how much a given, "test" text has in common with a corpus of possibly similar documents. If we concatenate the corpus and the test text, and gzip them together, the test text will get a better compression ratio if it has more fragments, words, or phrases in common with the corpus, and a worse ratio if it is dissimilar. Since the LZ algorithm scans the entire input for repetitions, it tends to map pieces of the test text to previous occurrences in the corpus, thereby achieving a high "appended compression ratio" if the test text is similar to what it's appended to. .
