To begin with the building of the cryptosystem, the contents of the records, transmitted from the patients' side as well as the loads of the staged data in the healthcare system, are to be presented in a commonly exchangeable columnar file format, this being the widely transferable arrangement of bulk data across the networks. Here, the data contents are considered to have the format of the comma-separated values (CSV), with the comma as the delimiter between the values of a record. The healthcare data set HC_DS containing the medical records of the patients is considered for illustration and is represented asHC_DS=recuvw,u=1tor,v=1tod,w=1toc,

The process of taking a line of input that contains a group of strings separated by some delimiter and breaking it into its individual substring components (or tokens) is sometimes called tokenizing. We will develop a specific tokenizer for use in our setting. The details involved in producing this function are somewhat irrelevant to our immediate purpose. Thus, the tokenizer method will be treated as a “black box” that takes a line of input and returns it to us in a vector container of string variables. The details of how the tokenizer works will be revealed at the end of the section.

delimiter a symbol, or sequence of symbols, that separates lexical entities in a programming language. The exact set of symbols that constitute delimiters is established by each programming language. Some delimiters are defined to occur in matching pairs, known as balanced delimiters.

Tokenization is the process of breaking the text into units, often in the form of words and sentences. When tokenizing, the delimiters that define a token (space, period, semicolon, etc.) need to be determined. For example, in English, space is used to determine a word. There are many tokenization packages in Python that deliver smart tokenization procedures, e.g. NLTK and StanfordCoreNLP. Regardless, researchers are advised to pay close attention to instances specific to the textual corpora. For example, when analyzing corporations’ 10-K filings, it is usually necessary to encode corporation name before tokenization.
