Abstract: Systems and method for sending a first alphacode to a first participant over a secure channel. Sending a second alphacode to a second participant over a secure channel. Receiving a first encoded message, a second encoded message, and a plaintext message. The first encoded message is based on the first alphacode and the second encoded message is based on the second alphacode. Generating a first ciphertext based on the first alphacode and the plaintext message. Comparing the first ciphertext to the first encoded message and determining the authenticity of the first encoded message based at least on the comparing to the first ciphertext. Comparing the second ciphertext to the second encoded message and determining the authenticity of the second encoded message based at least on the comparing to the second ciphertext. Sending a first confirmation to the first participant and sending a second confirmation to the second participant.

Abstract: An exemplary lens arrangement can be provided that includes a plurality of lenses configured to provide a field of view (FOV) of between about 9 mm×6 mm to about 15 mm×12 mm, a resolution at at least one edge of the lenses of between about 40 lp/mm to about 100 lp/mm, and a distortion between about 0.1% to about 1%.

Abstract: Exemplary systems, methods and computer-accessible mediums can receive information comprising a first speckle pattern(s) associated with a portion(s) of the paper. The information can be generated by an optical arrangement, and the first speckle pattern(s) can be compared with a second speckle pattern(s) to determine if a similarity, measure based on local or global descriptors is of equal to a predetermined amount or within a predetermined range.
