ABSTRACT: When
developing programs or websites, it is very convenient to use relational
databases, which contain powerful and convenient tools that allow to work with
data very flexibly and get the necessary information in a matter of
milliseconds. A relational database consists of tables and records in these
tables, each table must have a primary key, in particular, it can be a number
of BIGINT type, which is a unique index of a record in the table, which allows to fetch operation with
maximum speed and O (1) complexity. After the operation of writing a row to the
table of database, the program receives the row identifier ID in the form of a
number, and in the future this ID can be used to obtain this record. In the
case of a website, this could be the GET method of the http protocol with the entry
ID in the request. But very often it happens that the transmission of an
identifier in the clear form is not safe, both for business reasons and for
security reasons of access to information. And in this case, it is necessary to
create additional functionality for checking access rights and come up with a
way to encode data in such a way that it would be impossible to determine the
record identifier, and this, in turn, leads to the fact that the program code
becomes much more complicated and also increases the amount of data, necessary
to ensure the operation of the program. This article presents an algorithm that
solves these problems “on the fly” without complicating the application logic
and does not require resources to store additional information. Also, this
algorithm is very reliable since it is based on the use of hash functions and
synthesized as a result of many years of work related to writing complex
systems that require an increased level of data security and program
performance.
