In general, existing systems are lacking one or more of the fundamental principles required for absolute security and integrity of the system:

• unpredictability,
• reproducibility (auditability),
• transparency,
• non-repudiation, as well as,
• traceability and
• inspection of the draw process by an observer or the public.

However sophisticated the EDS may be – observing an electronic draw where a key is pressed on a computer and the winning numbers appear on screen leaves the observer wondering where these numbers came from. It is only adessoDraws that allows the public to retrace each individual step leading to the drawing of the winning numbers – and to reproduce these. This is a unique form of reproducibility, which even traditional, manual draw machines are unable to emulate.

Why do we place such emphasis on the quality criteria, if even a manual draw with a traditional draw machine cannot hope to meet them? Because we can!

Up to now, lottery providers have always been forced to compromise when choosing between systems with clear, inherent shortcomings.

adessoDraws is the first system that enables all quality criteria to be met without accepting any compromises.

adessoDraws is the world’s only method to completely meet the fundamental quality criteria for electronic draws. The principles underpinning the basic prerequisite for performing electronic draws are public trust (and trust of all stakeholders) in the applied method and thereby in the draw itself.

How does adessoDraws meet all the requirements?

All the systems we are aware of currently suffer from one of the following problems: they may be hardware random generators that use a physical process to determine the random numbers. By their very nature, it is impossible to predict the random numbers from a physical process of this type, which can be based on a quantum phenomenon. However, the generation of random numbers is complex and is not transparent, making it particularly difficult for lottery players to understand. Other solutions based on pseudo-random generators rely on the selection of a random seed. A seed is the initial value that is required for an existing and generally recognized deterministic algorithm to run the process to generate random numbers. The algorithm will always return the same values when using the same seed. Only the generation of the seed is truly a random act.

This simple procedure guarantees absolute unpredictability, non-repudiation, reproducibility, transparency, and comprehensibility. Anyone can inspect and understand the process – even the lottery players themselves.
