12. 12 Figure 12-2: Consumer Privacy Introduction  Scott McNealy of SUN Microsystems: “You have zero privacy now. Get over it!”  But privacy is strong in European Union countries and many other countries

13. 13 Figure 12-2: Consumer Privacy Credit Card Fraud and Identity Theft  Widespread Concern (Gartner) One in 20 consumers had suffered credit card number theft in 2002 One in 50 consumers had suffered identity theft in 2002 Only about a fifth of this is online, but online theft is growing the most rapidly

14. 14 Figure 12-2: Consumer Privacy Credit Card Fraud  “Carders” steal credit card numbers  Many merchants fail to protect credit card numbers stored on their servers  Carders test and sell credit card numbers  Criminals make unauthorized purchases  In U.S., limited to $50 loss if report promptly  Merchants also suffer fraud from carders

15. 15 Figure 12-2: Consumer Privacy Identity Theft Fraud  Criminals steal or compile considerable information about a person—name, credit card numbers, date of birth, social security number, address, etc.  Impersonate the victim to get buy things, get loans, etc.  With credit card fraud, victims find a problem in their next statement; but with identity theft, they may not know until they discover much later that their credit rating is ruined

16. 16 Figure 12-2: Consumer Privacy Tracking Customer Behavior  Within a website and sometimes across websites  Some information is especially sensitive (health, political leanings, etc.)  Access to data and analysis tools are revolutionizing the ability to learn about people

17. 17 Figure 12-2: Consumer Privacy Tracking Customer Behavior  What consumers wish for Disclosure of policies for  What information will be collected?  How this information will be used by the firm collecting the data?  Whether and with whom the information will be shared

18. 18 Figure 12-2: Consumer Privacy Tracking Customer Behavior  What consumers wish for Ability of consumer to see and correct inaccurate personal information Limiting collection and analysis to operational business needs  Limiting these needs Opt in: No use unless customer explicitly agrees

21. 21 Figure 12-2: Consumer Privacy Corporate Responses  Opt out: Customer must take action to stop data collection and sharing  No opt: No way to stop data collection and sharing  Passport and Liberty Alliance Identity management services Register once, giving personal information Give out to merchants selectively

22. 22 Figure 12-2: Consumer Privacy Consumer Reactions  Checking privacy disclosure statements (rare)  Not accepting cookies (rarer)  Anonymous websurfing services (extremely rare)

23. 23 Figure 12-2: Consumer Privacy U.S. Privacy Laws  No general law  Health Information Portability and Accountability Act (HIPAA) of 1996 Protects privacy in hospitals and health organizations Focuses on protected information that identifies a patient

31. 31 Figure 12-3: Employee Workplace Monitoring Why Monitor?  Loss of productivity because of personal Internet and e-mail use Significant personal Internet and e-mail use is occurring Employees and companies generally agree that a small amount of personal use is acceptable Biggest concern is abnormally heavy personal use Some employees are addicted to personal use

32. 32 Figure 12-3: Employee Workplace Monitoring Why Monitor?  Harassment Title VII of the Civil Rights Act of 1964: sexual and racial harassment Pornography, other adult content are fairly common Monitoring for keywords can reduce pornography and harassment and provide a legal defense

33. 33 Figure 12-3: Employee Workplace Monitoring Why Monitor?  Viruses and other malware due to unauthorized software  Trade secrets: Both sending and receiving must be stopped  Commercially damaging communication behavior: Can harm reputation, generate lawsuits, and run afoul of stock manipulation laws

36. 36 Figure 12-3: Employee Workplace Monitoring The Legal Basis for Monitoring  Unions often limit disciplining, agreement to be monitored However, new hires usually can be required to submit to monitoring as a condition of employment  In multinational firms, stronger privacy and employment rules might exist

37. 37 Figure 12-3: Employee Workplace Monitoring Should a Firm Monitor?  Danger of backlash  Are the negative consequences worth the gain?

38. 38 Figure 12-3: Employee Workplace Monitoring Computer and Internet Use Policy Should Specify the Following  No expectation of privacy  Business use only (or very limited private use)  No unauthorized software  No pornography and harassment  Damaging communication behavior  Punishment for violating the policy Employee Training in Policy is Crucial

58. 58 Figure 12-5: Cyberwar and Cyberterror Hardening the Internet  Hardening Internet protocols IETF is making progress by adding confidentiality, authentication, and other protections to core Internet protocols  The decision to do this is called the Danvers Doctrine Generally not using digital certificates in a public key infrastructure for strongest authentication

59. 59 Figure 12-5: Cyberwar and Cyberterror Hardening the Internet  Making the Internet forensic ISPs might be forced to collect and retain data for long periods of time ISPs might be forced to do egress filtering to stop attacks at the source The cost to ISPs would be high
