Modern Relevance of Invisible Ink Messages
As an indication of security, most inks mentioned above were already known by the end of World War I. However, in 1999, the U.S. Central Intelligence Agency successfully requested that a 1940s technical report on invisible ink remained exempt from mandatory declassification, based on the claim that invisible ink was still relevant to national security. The report thus remained classified until 2011.
Former MI-6 agent Richard Tomlinson alleges that Pentel Rolling Writer rollerball pens were extensively used by MI-6 agents to produce secret writing (invisible messages) while on missions.

Famous quotes containing the words modern, relevance, invisible, ink and/or messages:
“A building is akin to dogma; it is insolent, like dogma. Whether or no it is permanent, it claims permanence, like a dogma. People ask why we have no typical architecture of the modern world, like impressionism in painting. Surely it is obviously because we have not enough dogmas; we cannot bear to see anything in the sky that is solid and enduring, anything in the sky that does not change like the clouds of the sky.”
—Gilbert Keith Chesterton (1874–1936)
“Wherever the relevance of speech is at stake, matters become political by definition, for speech is what makes man a political being.”
—Hannah Arendt (1906–1975)
“They threw off their clothes, and he gathered her to him, and found her, found the pure lambent reality of her for ever invisible flesh. Quenched, inhuman, his fingers upon her unrevealed nudity were the fingers of silence upon silence, the body of mysterious night upon the body of mysterious night, the night masculine and feminine, never to be seen with the eye, or known with the mind, only known as a palpable revelation of living otherness.”
—D.H. (David Herbert)
“The self-styled intellectual who is impotent with pen and ink hungers to write history with sword and blood.”
—Eric Hoffer (1902–1983)
“All the old supports going, gone, this man reaches out a hand to steady himself on a ledge of rough brick that is warm in the sun: his hand feeds him messages of solidity, but his mind messages of destruction, for this breathing substance, made of earth, will be a dance of atoms, he knows it, his intelligence tells him so: there will soon be war, he is in the middle of war, where he stands will be a waste, mounds of rubble, and this solid earthy substance will be a film of dust on ruins.”
—Doris Lessing (b. 1919)
