Safer Internet: Keep Your Internet Connection Private

Summary

Recall the letter / post office analogy in Privacy, Security, Anonymity section?
We're mostly concerned about content (postcard vs. letter) -- encryption
The address (actual vs. PO Box) could be important too -- anonymity via indirection
The following figures show the effect of encryption from various techniques
What's not shown: which information might be added, e.g., ads, tracking, malware
which information might be saved on client or servers, e.g., history, logs, caches
how secure your data is on their server, e.g., passwords, medical records, credit card, social security no.
how someone else accesses information you've 'published', e.g., email recipient, blog reader
