To resolve the ethical issue of privacy, it is essential to maintain long-term customer data security. Ad blockers can be used to restrict ads from entering computer systems and potentially spreading viruses. Legal action can also be taken against privacy violators, with the European Union's General Data Protection Regulation imposing fines up to 5% of worldwide revenues on violators. Additionally, users should take responsibility for maintaining their system's security by locking it when not in use and using strong passwords. Anti-virus tools and firewalls can also be used to prevent virus attacks and restrict vulnerable objects from entering the system. In the business context, loyalty programs and e-receipts can be developed to maintain customer data privacy.
