Numerous studies in the field of cybernetics and bioengineering are beginning to bear fruit. Earlier models of chips implanted in the human body were used only for transmitting data about the owner to GlobalNet or a private hospital network, making purchases, computer access, or simply as a security pass for various places. They had many flaws, notably weak security, incomplete compatibility with networks, and (in rare cases) individual intolerance to components in the implanted chip. Identify theft and falsification of bank account data, passport data data, and health information were not uncommon. Recent research has allowed the chip to become a more active element in the human body and receive synaptic and biochemical data on the person’s health and mood. This has made it possible to link the security system to biochemical indicators; to introduce basic alterations, it is now necessary not only to have an individual access key, but to synchronize it with an overall indicator of the person's health, which must be done at a specialized center. The automatic security systems of public buildings are able to deny access if a person is aggressively minded or advise patients to seek medical assistance if their vital signs worsen. Cars will be blocked if drivers are in a depressed, aggressive, or intoxicated condition, or switch to autodrive if the indicators deteriorate on the road. For the seriously ill, special chips will be able to transmit health data to a hospital’s neural network via an additional element (embedded in a watch, bracelet, ring, communication device, or other preferred accessory) that also functions as a firewall. Modern 3D printing technologies in the field of medicine have solved the problem of biological compatibility—now chips are combined with cellular adsorbents based on the body’s own cells.
