Cryptography

Anonymous matching

Anonymous matching is a matchmaking method facilitated by computer databases, in which each user confidentially selects people they are interested in dating and the computer identifies and reports matches to pairs of users who share a mutual attraction. Protocols for anonymous matchmaking date back to the 1980s, and one of the earliest papers on the topic is by Baldwin and Gramlich, published in 1985. From a technical perspective, the problem and solution are trivial and likely predate even this paper. The problem becomes interesting and requires more sophisticated cryptography when the matchmaker (central server) isn't trusted. The purpose of the protocol is to allow people to initiate romantic relationships while avoiding the risk of embarrassment, awkwardness, and other negative consequences associated with unwanted romantic overtures and rejection. The general concept was patented on September 7, 1999, by David J. Blumberg and DoYouDo chief executive officer Gil S. Sudai, but several websites were already employing the methodology by that date, and thus apparently were allowed to continue using it. United States Patent 5,950,200 points out several potential flaws in traditional courtship and in conventional in which strangers meet online, promoting anonymous matching of friends and acquaintances as a better alternative: Human relationships are often fraught with difficulties. In addition, human beings are risk-averse. Often, even when two people want to initiate first steps in a relationship, neither person takes action because of shyness, fear of rejection, or other societal pressures or constraints. Various systems exist that help people meet each other. For example, allow people to view video tapes or pictures of prospective partners or to choose common areas of hobbies. Two people are introduced only if both agree with the idea. Unfortunately, in such situations, neither person has actually met the other when they are finally introduced. Neither person has ever met the other, and there is a certain amount of shyness and fear of rejection when they first meet in such a situation. In addition, both persons must initially approach the dating service. For some people, such an action can also be embarrassing. What is needed is a safe, simple, confidential, and non-judgmental way for people to reveal their true feelings and interests without risk of embarrassment or rejection. (Wikipedia).
