Privacy tips from HELP.org:
Social Media: If you post information, pictures, etc. on social media it is no longer private. Even if it deleted at a later time it may have already been copied in other places.
Passwords: Many people use easy-to-remember passwords which are also vulnerable to attack. When passwords are reused a hacker can gain access to many different accounts of the victim. A password vault that creates different, random passwords for each of your web sites. One free program is at http://keepass.info/
Password Recovery: The password recovery feature is often used to break into accounts, often with the use of information posted on social media, to find the answers to the questions.
Email address: Malware and Viruses are often distributed via email. Keep multiple email addresses: one for social media, one for shopping and another for important accounts for things such as banking. This way spammers will not get the addresses used for your important accounts.
Use a separate device for important things: Use another computer when accessing important web sites such as banking. An old computer where the operating system is reloaded is a good choose. Using old operating systems may be a bad choice because of security flaws.
Credit reports: Check your credit reports (the free site is at https://www.annualcreditreport.com/). Any mistakes should be disputed. A dispute may take multiple letters and you may receive cryptic or incomplete responses. Multiple letters and escalations, along with copies of complaints to the Federal Trade Commission, will often resolve the disputes.
Bitcoin is an experimental electronic payment system and currency. The system is decentralized and payments are not reversible. Merchants who accept Bitcoin do not need to collect personal information for payment verification. If they don’t collect it, they can’t lose it. It is possible to buy Bitcoins by linking to your bank account at places like Coinbase.com. Some places offer Bitcoin Discounts which can compensate for the exchange fees.
