  1. Hello Professor.
  2. There's going to be the presentation about the metric field
  3. of my my and Mr Lopez.
  4. So within the few a biometric data, three ways to
  5. identify a person by what they process.
  6. So such as the first one I did like the
  7. very common way to check a person that's a citizenship
  8. of the United States.
  9. Uh And that's a must have item so we can
  10. always uh know who they are.
  11. And the second one is not the personal information such
  12. as password means.
  13. Because that one is probably only likely only that person
  14. know that information.
  15. In the 3rd 1 is the very more than one
  16. is parametric marker.
  17. Uh So for some example of the biometric market is
  18. going to be fingerprint facial figures.
  19. Such a person years and no iris voice signature, hand
  20. geometry and even older on the stench age limit.
  21. So in a biometric there are three key terms uses
  22. to recognize and identity.
  23. But the first one is the recognition also know as
  24. the alternative authentication in system that allows you to know
  25. again a person who you have grievously met.
  26. The second one is the verification which allow your system
  27. to as itself it is a person who they say
  28. they are by checking the system to fire biometric file
  29. of the of the person you have met previously identification.
  30. And the second one, the last one is identification is
  31. then used to spy the system to determine in individually
  32. identity years in biometric data that is collected and compared
  33. to the template in our database for our closest closes
  34. set or an open set investigation.
  35. So in the clothes is set at certification.
  36. The investigator invest investigators know that the person exists in
  37. the day of in the database but opposite lee in
  38. the open set.
  39. The investigator don't know who they who that person is
  40. in a database.
  41. So uh typically biometric system comprises five.
  42. Uh It's a great component.
  43. So the first one is going to be the sensor
  44. which is collected data and convert them into digital Portman.
  45. The second one is the signal processing colorism that performing
  46. the quality control activity and developed a biometric template.
  47. The 3rd 1 is that they a data storage component
  48. that keep information that new parametric template will be compared
  49. to. Um and the 4th 1 is the machine our
  50. region that compared the new biometric template to one or
  51. more template kept in the data storage.
  52. And finally the decision process it out.
  53. Either the ultimate or human existed.
  54. You see the result from a marching component to make
  55. a system level decision.
  56. Hey. And yeah, despite the fact that the biometric, despite
  57. the fact that Obama tree funds, for instance, involves studying
  58. human recognition and even working together in many ways, they
  59. are still fundamentally different study with different function.
  60. Volumetric typically uses the ultimate technique, such a fingerprint scanner,
  61. uh, and iris data pay before the event occurred.
  62. Such a template to gain access to sensitive information or
  63. to secure the fact facility.
  64. My contract, for instance, application typically used automate or non
  65. ultimate technique.
  66. Such add hair or fiber analyzes and data by examination
  67. after the crime has been committed.
  68. The for instance, methods are used to as if the
  69. legal process to return my guilty or in notion and
  70. that's the all about our information.
  71. The function of the biometric.
  72. Thank you for listening.
