How do you ensure that information is secure?

Corresponding to each certificate a token is generated. This token is actually an encryption hash result/key which will be stored in the blockchain too. If the certificate changes (even one character of it), the hash changes. This means the time of creation of the hash (i.e. the registration of certificate) can be proven with the actual certificate and the token hash. With the token hash alone, the certificate can’t be recreated, which gives pretty good  security for the contents of the certificate as well.
