  1. 1. Matterhorn Business Solutions Tel. 587-350-1082 Email: david@matterhornsolutions.ca http://matterhornsolutions.ca/calgary-tech-support/ Computer Security Trends Enforcing Digital Security via User Authentication
  2. 2. Matterhorn Business Solutions Tel. 587-350-1082 Email: david@matterhornsolutions.ca http://matterhornsolutions.ca/calgary-tech-support/ In our day-to-day technical support for Calgary companies, one of the most common I.T. requests is the password reset.
  3. 3. Matterhorn Business Solutions Tel. 587-350-1082 Email: david@matterhornsolutions.ca http://matterhornsolutions.ca/calgary-tech-support/ The simple text password is one of the most basic forms of authentication. There are, however, many other ways to authenticate access to a resource. In this article we discuss computer security trends.
  4. 4. Matterhorn Business Solutions Tel. 587-350-1082 Email: david@matterhornsolutions.ca http://matterhornsolutions.ca/calgary-tech-support/ Authentication is used to verify the users identity to control access to the resources to prevent unauthorized users from accessing the system, and to store system logs about users activities.
  5. 5. Matterhorn Business Solutions Tel. 587-350-1082 Email: david@matterhornsolutions.ca http://matterhornsolutions.ca/calgary-tech-support/ There are two basic modes of authentication: Verification (a 1-to-1 comparison) Identification (a 1-to-many comparison)
  6. 6. Matterhorn Business Solutions Tel. 587-350-1082 Email: david@matterhornsolutions.ca http://matterhornsolutions.ca/calgary-tech-support/ There are 3 basic authentication methods: Something we know (password, key sequence etc.) Something we have (token, smartcard etc.) Something we are (biometrics fingerprints, eye scan etc.)
  7. 7. Matterhorn Business Solutions Tel. 587-350-1082 Email: david@matterhornsolutions.ca http://matterhornsolutions.ca/calgary-tech-support/ However, passwords can be stolen or tokens can be lost. Therefore, enter biometrics.
  8. 8. Matterhorn Business Solutions Tel. 587-350-1082 Email: david@matterhornsolutions.ca http://matterhornsolutions.ca/calgary-tech-support/ Biometric authentication is a process of analysis of someones physical characteristics, or behavioral aspects, in order to prove the persons identity.
  9. 9. Matterhorn Business Solutions Tel. 587-350-1082 Email: david@matterhornsolutions.ca http://matterhornsolutions.ca/calgary-tech-support/ The phrase biometrics comes from the Greek language: bio (= life) and metric (= to measure). A well-known concept for biometrics is the use of fingerprints for personal identification, at a police station for example.
  10. 10. Matterhorn Business Solutions Tel. 587-350-1082 Email: david@matterhornsolutions.ca http://matterhornsolutions.ca/calgary-tech-support/ A good biometric method should possess the following 3 properties: Broadness: almost all people should have the characteristic. Stability: the characteristic should not change or mutate. Exclusiveness: the characteristic of each person should be unique.
  11. 11. Matterhorn Business Solutions Tel. 587-350-1082 Email: david@matterhornsolutions.ca http://matterhornsolutions.ca/calgary-tech-support/ The biometric authentication can be completed in 2 ways: Physical characteristics recognition based on some physical feature for identification and authentication, like fingerprints. Behavioral characteristic recognition based on some dynamic characteristics, such as keyboard typing, writing, or a hand signature.
  12. 12. Matterhorn Business Solutions Tel. 587-350-1082 Email: david@matterhornsolutions.ca http://matterhornsolutions.ca/calgary-tech-support/ Common biometric technologies are: Face biometrics Fingerprint biometrics Eye biometrics Hand geometry biometrics Signature biometrics Voice biometrics
  13. 13. Matterhorn Business Solutions Tel. 587-350-1082 Email: david@matterhornsolutions.ca http://matterhornsolutions.ca/calgary-tech-support/ Less commonly used biometric technologies: Keystroke dynamics Vein recognition Body odor measurement Palm-print Gait recognition Ear shape DNA recognition
  14. 14. Matterhorn Business Solutions Tel. 587-350-1082 Email: david@matterhornsolutions.ca http://matterhornsolutions.ca/calgary-tech-support/ These are just some of the biotechnologies that we can expect to commonly see in the future.
