Abstract: A method performed at a first electronic device includes: (i) storing a privacy table that comprises random numbers at the first electronic device, (ii) transmitting the privacy table to a second electronic device over an encrypted channel, (iii) receiving a first message for transmission to the second electronic device, (iv) generating a map based on the privacy table, (v) generating a primary key based on the map and the privacy table, and (vi) encrypting the first message using the primary key to form an encrypted first message. The method also includes (vii) transmitting the map and the encrypted first message to the second electronic device, thereby enabling the second electronic device to decrypt the encrypted first message by recreating the primary key based on the map and the privacy table and decrypting the encrypted first message using the recreated primary key.

Abstract: An apparatus generates truly random numbers. The apparatus includes a container that is at least partially filled with a fluid (e.g., water or air). The apparatus also includes objects (e.g., dice) suspended freely in the fluid. The apparatus includes agitators configured to stir the fluid, and cameras configured to capture images of the objects. When the agitators stir the fluid, the objects move freely (e.g., move with the created currents) in the fluid in the container. The apparatus also includes a random number generation circuit coupled to the cameras. The random number generation circuit is configured to generate random numbers based on the images captured by the cameras.

The random number generation circuit is configured to generate random numbers based on the images captured by the cameras. In some embodiments, the agitators are one or more motor-driven propellers that stir the fluid. Some embodiments use a hydraulic pump to agitate the fluid (e.g., circulating the fluid using both a push action and a pull action).

Abstract: A random dice generator having a rack, a die table coupled to the rack, an arm rotatable coupled to the rack, a tumbler cup coupled to the arm opposite the arm coupling to the rack, and at least one image capture device. The arm can be rotatable between a loading position and a rolling position. The tumbler cup can receive at least one die when the arm is in the loading position and the tumbler cup releasing the at least one die into the die table when the arm is in the rolling position. The at least one image capture device determining the value of the at least one die received in the die table.
