1. PRISM

   PRISM is a code name for a program under which the United States National Security Agency (NSA) collects internet communications from various U.S. internet companies. The program is also known by the SIGAD US-984XN. PRISM collects stored internet communications based on demands made to internet companies such as Google LLC under Section 702 of the FISA Amendments Act of 2008 to turn over any data that match court-approved search terms. Among other things, the NSA can use these PRISM requests to target communications that were encrypted when they traveled across the internet backbone, to focus on stored data that telecommunication filtering systems discarded earlier, and to get data that is easier to handle.PRISM began in 2007 in the wake of the passage of the Protect America Act under the Bush Administration. The program is operated under the supervision of the U.S. Foreign Intelligence Surveillance Court (FISA Court, or FISC) pursuant to the Foreign Intelligence Surveillance Act (FISA). Its existence was leaked six years later by NSA contractor Edward Snowden, who warned that the extent of mass data collection was far greater than the public knew and included what he characterized as "dangerous" and "criminal" activities. The disclosures were published by The Guardian and The Washington Post on June 6, 2013. Subsequent documents have demonstrated a financial arrangement between the NSA's Special Source Operations (SSO) division and PRISM partners in the millions of dollars.Documents indicate that PRISM is "the number one source of raw intelligence used for NSA analytic reports", and it accounts for 91% of the NSA's internet traffic acquired under FISA section 702 authority." The leaked information came after the revelation that the FISA Court had been ordering a subsidiary of telecommunications company Verizon Communications to turn over logs tracking all of its customers' telephone calls to the NSA.U.S. government officials have disputed criticisms of PRISM in the Guardian and Washington Post articles and have defended the program, asserting that it cannot be used on domestic targets without a warrant. Additionally claiming the program has helped to prevent acts of terrorism, and that it receives independent oversight from the federal government's executive, judicial and legislative branches. On June 19, 2013, U.S. President Barack Obama, during a visit to Germany, stated that the NSA's data gathering practices constitute "a circumscribed, narrow system directed at us being able to protect our people."

1. prism

   A prism is a type of geometric solid or three-dimensional figure that possesses a pair of identical and parallel faces known as the bases. The other faces, often referred to as lateral faces, are parallelograms or rectangles connecting the corresponding sides of the bases. The shape of the prism is typically determined by the shape of the bases. For instance, if the base is a rectangle, it is called a rectangular prism; if the base is a triangle, it is called a triangular prism, and so on.

1. Prism

   In optics, a prism is a transparent optical element with flat, polished surfaces that refract light. At least two of the flat surfaces must have an angle between them. The exact angles between the surfaces depend on the application. The traditional geometrical shape is that of a triangular prism with a triangular base and rectangular sides, and in colloquial use "prism" usually refers to this type. Some types of optical prism are not in fact in the shape of geometric prisms. Prisms can be made from any material that is transparent to the wavelengths for which they are designed. Typical materials include glass, plastic and fluorite. A prism can be used to break light up into its constituent spectral colors. Prisms can also be used to reflect light, or to split light into components with different polarizations.
