WIPO PROOF – Trusted Digital Evidence

WIPO PROOF provides a date- and time-stamped digital fingerprint of any file, proving its existence at specific point in time.

The WIPO PROOF service was launched as a pilot program by WIPO in 2020 and has been followed by a number of similar initiatives in the public and private sector. 

Following a review of the pilot program as part of WIPO’s planning and budget review, it was decided to discontinue the WIPO PROOF service.

The token generation service will be discontinued on January 31, 2022.  For existing account holders, the storage and validation services for previously generated tokens will remain available for a further 5 years from that date.

More information can be found on the WIPO PROOF website.
