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:
“An ... important antidote to American democracy is American gerontocracy. The positions of eminence and authority in Congress are allotted in accordance with length of service, regardless of quality. Superficial observers have long criticized the United States for making a fetish of youth. This is unfair. Uniquely among modern organs of public and private administration, its national legislature rewards senility.”
—John Kenneth Galbraith (b. 1908)
“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)
“Good poetry could not have been otherwise written than it is. The first time you hear it, it sounds rather as if copied out of some invisible tablet in the Eternal mind than as if arbitrarily composed by the poet.”
—Ralph Waldo Emerson (1803–1882)
“Language has not the power to speak what love indites:
The Soul lies buried in the ink that writes.”
—John Clare (1793–1864)
“Acknowledging separation feelings directly and sympathetically is the best way of coping with them. It is actually helpful to tell a toddler “I’ll miss you,” or “I will think of you during the day,” or “It is hard to say goodbye,” or “I can’t wait to see you at the end of the day.” These messages tell the child that he is important to the parent even when they are not together and that out of sight need not mean out of mind.”
—Alicia F. Lieberman (20th century)
