Cryptographic 2-way time-stamping
Below are some figures from the technical paper on alibi sousveillance:
is a brief biography on the inventor, Steve Mann; and also
Wikipedia has more info on
inventor S. Mann.
- Invention title: Alibi Sousveillance
Summary explanation -- how it works:
Presently time-stamps only work in a one-sided way: you submit something
to show it existed at the time the stamp was given.
Our invention bounds the time in both directions, e.g. to prove
that a video or photograph or other data was captured within a certain
time bound: neither before or after that range of time.
Cryptographic elements can depend on a BITCOIN blockchain which can't be
forged (i.e. history can't be rewritten).
This is very useful for wearable cameras, for example, to make timecodes
easily proveable by any third party.
- Example commercial applications:
- Police forces, or service workers can wear a special e-ink patch
that ensures any records of an incident are automatically time-stamped.
Individuals and organizations alike can time-stamp wearable camera data
to prevent being framed, or false accusations.
- Utility workers, military service members, journalists, etc.,
can be protected from false allegations.

- Patent applications filed or issued: In progress.
- Prototypes constructed: Several working prototypes have been constructed
by S. Mann and Mir Adnan Ali,
but additional work is required for commercialization.
- Further possibilities: This work is done jointly by S. Mann and
Mir Adnan Ali.
