Not Before Time

The practical design NotBeforeTime v2.4 has gone through many iterations and a lot of critical peer review. With assorted working prototypes and a healthy debate among .

The paper explains in mostly non-technical language how:

Not Before Time combines existing technology to give three strong guarantees that particular information:

1. will not be readable before a certain future time
2. was not created before a certain past date and time
3. was not electronically signed before a certain time

These support human rights, democracy, health and business.

The health aspect addresses the mental stressors explored in recent work such as Dr Mark Rego in his Frontal Fatigue.

The novel features of Not Before Time are:

• Time locking information is the opposite of the modern and stressful trend for all information to be available instantly, everywhere.
• The three guarantees work for ordinary users using their everyday software on their existing devices.
• The mechanism and its novel new applications as easily explained to non-technical people, which is essential for a system to be trusted.

Validation

I have discussed Not Before Time in detail with:

• Well-known crytographers, who concur that all of the techniques involved are understood and can be rapidly and reliably implemented
• Existing maintainers of broadcast technologies, including the global Domain Name System, distributed network time systems, and a Magellen satellite ground station.
• Likely early commercial adopters, including law firms, construction tender companies and auction houses
• Human rights and whistleblower defense representatives
