It is not a cryptographic algorithm given no key nor nonce. it is an obfuscation function that can only hide some obvious patterns (it can be still useful, but not in a cryptographic way). I want to give you a benefit of doubt, but a "cryptography" tag makes me nervous enough. Also it seems that there is no justification why such a complex approach is required; the typical approach is to use typical symmetric encryption algorithms with fixed key and nonce.
