    摘要: A system and method for data analysis and digital forensics is provided. The system for data analysis and digital forensics may include: an online data forensic server for collecting and analyzing usage history information from an object device, which is subject to data collection, downloading and collecting data on the Internet based on the usage history information, requesting issuance of a timestamp token for the collected data, and receiving the issued timestamp token; a timestamp token issuing server for issuing the timestamp token for the collected data in response to the request for issuance of the timestamp token and proving the issued timestamp token to the online data forensic server; and a storage device for storing the collected data.

    摘要: A method of iris recognition using a cumulative-sum-based change point analysis and an apparatus using the same are disclosed. The method includes: transforming an iris image to a polar coordinated image having n×m pixel size and dividing the polar coordinated image into at least one cell; grouping the divided iris images into at least one of first groups having a predetermined number of cells, and at least one of second groups each having more cells than the first group has; performing a cumulative-sum-based change point analysis using a predetermined characteristic pattern value of each cell as a representative value; and generating a pattern vector by assigning a predetermined value to a cell having the change point and assigning a different value to other cells.

    摘要: An iris recognition method is provided. In the iris recognition method, binary image data is obtained by receiving eye image data and filtering the received eye image data using a predetermined threshold value. Then, candidate center search regions are searched for finding a pupil center using profile information of rows and columns of the binarized image. a pupil boundary and a center point are detected by performing a mask operation using 8 pupil boundary mask templates for each of concentric circles formed of pointes in the searched candidate center search regions as candidate pupil centers and different radiuses. An iris boundary region is detected by performing a masking operation using 6 iris boundary mask templates corresponding to 6 locations for concentric circles formed of the pupil center as an origin and different radiuses.
