Humaniq - is one of them but they use face recognition in the app like prof of person.
Persona - is another one but they seem to be like ID management system based on block chain which
seems like more traditional KYC process which requires documents.
Humaniq is only ETH token. It is far from coin based on innovative Proof of person blockchain. Humaniq exist for 2.5 year and was worth at ath 90M $ ... IDENA is currently worth ~450$ (supply multiplied by lowest sell price on discord OTC)
Persona is also not Proof of person blockchain. It is a system to share your KYC data with others in a way to not loose control over them. Persona is also a scam project (only my assumption) because they put that on their website:
And according to CZ every project that share info about progress of listing before their official announcement is a scam project or have dump team who does not read terms and conditions of listing.
They are both completely different from IDENA.
