comment fuzzy commitment implemenation to make secure biometric template
This doesn't answer your question, but if I were you, I'd contact the authors and see if they can share their source code.

comment fuzzy commitment implemenation to make secure biometric template
I updated the language in your question and added links to freely available versions of the paper. I hope I didn't change the original meaning. If I did, feel free to edit. I'll reopen and we'll see what the community here says.

comment Encryption with data loss protection
Now, specifically what "security" pillars do you care about? The typical pillars we see are confidentiality (only who you say can have the book can have it), integrity (that the book hasn't changed), authenticity (that the book came from you, or that you are really the one who sent it to them).

comment Encryption with data loss protection
What @poncho says is along the right track, but it sounds like you want your distributed book to be "error tolerant". In other words, if some parts of the file get corrupted, the person should still be able to read and verify it. Is that correct?

comment salsa20 is invertible, useless in CTR mode?
How exactly do you use salsa20 in block cipher CTR mode? Salsa20 is not a block cipher, it is a stream cipher.

comment Can Bitcoin HD public keys be used for symmetric encryption?
@sylarmorgan If the keys are good, publishing i shouldn't matter. It is used in generating the public key, but there is (hopefully) enough additional entropy there that it wouldn't matter. For example, if I generated keys to encrypt messages to you as Hash(really_long_shared_secret || i) and sent to you i and a message encrypted with the key, the attacker knowing i doesn't help them very much. In the encryption, there are ways we could mess up (for example, this key generation is deterministic, so we would have to use good IV's as input to the block cipher, etc).
