Explanation:

1. "Only a small fraction of the information flowing around the world is securely encrypted" directly shows that most information is not secure as it is not encrypted.
2. "Few of these people take adequate precautions in terms of privacy" implies lack of security - related actions, thus information is not secure.
3. "Law enforcers and anybody else with a curious mind can get their hands on more information" indicates that information is accessible to many, meaning it's not secure. The line about mathematics and the one about shielding material are not relevant to the idea of information - security.

Answer:

1. Only a small fraction of the information flowing around the world is securely encrypted
2. few of these people take adequate precautions in terms of privacy
3. law enforcers and anybody else with a curious mind can get their hands on more information
