How to prove a digital existence of a file or work?

WIPO announced its new service called WIPO PROOF. It  produces tamper-proof evidence regarding the existence of a digital file at a specific time.

The service doesn’t prove authorship or anything else then the fact that the relevant work or file exists at a particular moment.

This could be useful in different intellectual property disputes where a priority date has to be proved.

WIPO acts as a time-stamping authority by issuing a token (a unique digital fingerprint of a digital file in any format and size) which is generated and stored on WIPO servers in Switzerland. The service doesn’t use block-chain technology for the time being.

The following categories of intellectual property and other files and data can use WIPO PROOF: 

  • Trade secrets
  • Creative works
  • Creative designs 
  • Industrial designs
  • Software code  
  • Research
  • Data
  • Digitally signed document
  • Other

WIPO PROOF tokens do not expire but they are kept on WIPO’s servers for 5 years. This period can be renewed for another 5 years by paying a fee. 

The initial cost of one token which is equal to one file is 20 Swiss francs. A bundle of 10 tokens will cost 190 Swiss francs, whereas 100 tokens will cost 1800 Swiss francs.
