The task of clustering Web sessions is to group Web sessions based on similarity and consists of maximizing the intra- group similarity while minimizing the inter-group similarity． The first and foremost question needed to be considered in clustering W b sessions is how to measure the similarity between Web sessions．However．there are many shortcomings in traditiona1 measurements．This paper introduces a new method for measuring similarities between Web pages that takes into account not only the URL but also the viewing time of the visited web page．Yhen we give a new method to measure the similarity of Web sessions using sequence alignment and the similarity of W eb page access in detail Experiments have proved that our method is valid and e币cient．

Atmel’s AT91SAM7FP105 is a low pincount FingerChip processor based on the 32-bit ARM RISC processor. It features a on-chip biometric engine performing enrollment verification and identification, an internal record cache of up to 25 records and a secure command protocol over USB, SPI, UART. This protocol enables an external host system or processor to control the onchip bioengine functions, manipulate the record cache, and securely export record cache records for external storage. Together with the FingerChip sensor device AT77C104B, it forms an embedded, secured biometric turnkey solution.
