For vi bruger det hele tiden – internettet. Vi sender billeder og e-mails, som ingen andre må kunne se eller læse. Vi kontrollerer vores penge, forsikringer og sundhedsoplysninger via internettet. Trafiklys, energiforsyning, dankortterminaler – alt sammen er sluttet til internettet.
Og ingen har kontrol over hvilke veje, de mange informationer tager kloden rundt, før de når frem til den rette modtager. Alle med onde hensigter kan derfor se eller læse med og bruge oplysningerne til at udløse den store personlige eller samfundsmæssige katastrofe.
Derfor er det altafgørende, at kun den rigtige modtager har nøglen til at låse beskeden op.

Ruthie's Table 4
For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
