A seal is a device for making an impression in wax, clay, paper, or some other medium, including an embossment on paper, and is also the impression thus made. The original purpose was to authenticate a document, a wrapper for one such as a modern envelope, or the cover of a container or package holding valuables or other objects.
The seal-making device is also referred to as the seal matrix or die; the imprint it creates as the seal impression (or, more rarely, the sealing). If the impression is made purely as a relief resulting from the greater pressure on the paper where the high parts of the matrix touch, the seal is known as a dry seal; in other cases ink or another liquid or liquefied medium is used, in another color than the paper.
In most traditional forms of dry seal the design on the seal matrix is in intaglio (cut below the flat surface) and therefore the design on the impressions made is in relief (raised above the surface). The design on the impression will reverse (be a mirror-image of) that of the matrix, which is especially important when script is included in the design, as it very often is. This will not be the case if paper is embossed from behind, where the matrix and impression read the same way, and both matrix and impression are in relief. However engraved gems were often carved in relief, called cameo in this context, giving a "counter-relief" or intaglio impression when used as seals. The process is essentially that of a mould.

datagram Lockwiki.com Tamper evident technologies are quickly becoming an interesting topic for hackers around the world. DEF CON 18 (2010) held the first ever "Tamper Evident" contest, where contestants were given a box sealed with a variety of tamper evident devices, many of which purport to be "tamper proof." All of these devices were defeated, even by those with little experience and a limited toolkit. Like the computer world, many of these devices are overmarketed and it is difficult for the average person to compare different tamper evident technologies. This talk covers the design and uses of tamper evident devices used in the commercial and government sectors. We'll dig into the nitty gritty of how many of these devices work, the methods by which they can be defeated, and live de...

An interview with an self-proclaimed ex-Navy Seal who during the years 1992-2000 was sent on top secret bombing missions in the Middle East, predominantly in Iraq. Years after the first Gulf War when we were supposedly not at war with Iraq yet he and Seal Team 9 were targeting Tomahawk Missiles on a monthly basis taking out targets that were increasingly "soft"... involving deaths of hundreds of innocent civilians. Find out how this highly trained young man and his team were coerced by the military into purposely destroying villages and creating future terrorists as part of a plan that would ultimately serve their dark purpose, the war on terror and 911. And if that weren't enough, hear how he was trained in Area 51 as a specially gifted group of highly classified psi spies to see beyond ...
