Definitions and quotes

Information
Information is any entity or form that provides the answer to a question of some kind or resolves uncertainty. It is thus related to data and knowledge, as data represents values attributed to parameters, and knowledge signifies understanding of real things or abstract concepts. As it regards data, the information's existence is not necessarily coupled to an observer (it exists beyond an event horizon, for example), while in the case of knowledge, the information requires a cognitive observer.
Security
Security is freedom from, or resilience against, potential harm (or other unwanted coercive change) from external forces. Beneficiaries (technically referents) of security may be persons and social groups, objects and institutions, ecosystems, and any other entity or phenomenon vulnerable to unwanted change by its environment.
Information
As I understand the theory of period information doubling, this states that if we take one period of human information as being the time between the invention of the first hand axe, say around 50,000 BC and 1 AD, then this is one period of human information and we can measure it by how many human inventions we came up during that time. Then we see how long it takes for us to have twice as many inventions. This means that human information has doubled. As it turns out, after the first 50,000-year period, the second period is about 1500 years, say around the time of the Renaissance. By then we have twice as much information. To double again, human information took a couple of hundred years. The period speeds up—between 1960 and 1970, human information doubled.
As I understand it, at the last count human information was doubling around every 18 months. Further to this, there is a point sometime around 2015 where human information is doubling every thousandth of a second. This means that in each thousandth of a second we will have accumulated more information than we have in the entire previous history of the world. At this point I believe that all bets are off. I cannot imagine the kind of culture that might exist after such a flashpoint of knowledge. I believe that our culture would probably move into a completely different state, would move past the boiling point, from a fluid culture to a culture of steam.
Alan Moore The Mindscape of Alan Moore (2003)

Security
Everywhere, men resign themselves to the most extreme sacrifices rather than do without government and hence security, without realizing that in so doing, they misjudge their alternatives.Suppose that a man found his person and his means of survival incessantly menaced; wouldn't his first and constant preoccupation be to protect himself from the dangers that surround him?  This preoccupation, these efforts, this labor, would necessarily absorb the greater portion of his time, as well as the most energetic and active faculties of his intelligence.  In consequence, he could only devote insufficient and uncertain efforts, and his divided attention, to the satisfaction of his other needs.
Even though this man might be asked to surrender a very considerable portion of his time and of his labor to someone who takes it upon himself to guarantee the peaceful possession of his person and his goods, wouldn't it be to his advantage to conclude this bargain?
Still, it would obviously be no less in his self-interest to procure his security at the lowest price possible.
