We've been hard at work these last few months testing and debugging the site, we would now like to invite the community to participate in beta testing!  Grin
Please see site updates in OP, more information coming soon.

Implemented search API.
Docker containers now available for easy bip32 key generation and encrypted string decoding for account verification.
Links now available in OP.

Connections to cryptoproof.info now encrypted using modern cypher suite TLS 1.2

Now on KICKSTARTER and STARTJOIN

Instructional video for account creation and verification now available on youtube here.

So what exactly does this service do you?
Please refer to the opening post for details.

looks like there is some potential here, why is the thread is so dead?
i like this but how can it work for things that are 3D printed if you cant tell them apart because it means they are identical?

how can it work for things that are 3D printed if you cant tell them apart because it means they are identical?
In the future when you order an item from a vendor such as a cup or a toy for example it seems sensible to envision a scenario where rather than have the vendor mail it to you or send it by drone they instead send the blueprint to your 3D printer which produces the item instantly for you at home or maybe they print the item for you themselves and then physically send it but in either case how can you know that you purchased the item from the producer in question and not someone who ordered an item themselves, intercepted the blueprint or scanned the product which was delivered to them and just sold you a clone? (this is a huge problem in the pharmaceutical industry)

Cryptoproof solves this by providing a common place where vendors can register master cryptographic keys and then brand each item with a unique subkey which cryptoproof can verify so that the consumer can know if the product originates from the producer that they think it does (by seeing if a verified account is associated with it) and if there is more than one copy of that item in existence (by seeing if/how many times that key has been submitted in the past).

Using Bitcoin keys for this purpose adds an extra dimension to the scenario because, for instance, value can be transmitted to and from these keys which allows not only for verification but also can be used to keep an immutable record showing how much was paid for the item, who paid it and when the transaction took place.

Interesting. Can you explain what this solves that public key certificates don't solve ?

This is how ssl certificates work too ...you sign using your private key and then user can verify using publickey. Same thing can be done with bitcoin public/private keys pair. For products, the vendor can the sign something like a product code and user can verify the signature .

Hello and thank you for your question, I will add it to the FAQ Smiley
  • In essence we log the number or hits each subkey receives and so provide an indication to the consumer as to whether their particular item is unique or not.
  • The consumer is also able to see at a glance who the registered vendor is without having to understand what an SSL certificate is and how to verify it's signature, we take care of that for them by getting the vendor to verify their identity in advance using the SSL certificate provided at the https url they own.
  • An added advantage to this is that value may be sent to this key because it is a valid address on the BTC network which is a feature the vendor may make use of if they wish.
  • Vendors are also able to monitor the number of hits each subkey has received which can be used for analytical reasons.
