Confidentiality in the context of Cryptographic

The Hippocratic Oath is an oath of ethics historically taken by physicians. It is one of the most widely known of Greek medical texts. In its original form, it requires a new physician to swear, by a number of healing gods, to uphold specific ethical standards. The oath is the earliest expression of medical ethics in the Western world, establishing several principles of medical ethics which remain of paramount significance today. These include the principles of medical confidentiality and non-maleficence. As the foundational expression of certain principles that continue to guide and inform medical practice, the ancient text is of more than historic and symbolic value. It is enshrined in the legal statutes of various jurisdictions, such that violations of the oath may carry criminal or other liability beyond the oath's symbolic nature.

Espionage, spying, or intelligence gathering, as a subfield of the intelligence field, is the act of obtaining secret, confidential, or in some way valuable information. Such information is also referred to as intelligence. A professional trained in conducting intelligence operations by their government may be employed as an intelligence officer. Espionage may be conducted in a foreign country, domestically or remotely. The practice is clandestine, as it is by definition unwelcome. In some circumstances, it may be a legal tool of law enforcement and in others, it may be illegal and punishable by law.

Espionage is often part of an institutional effort by a government or commercial concern. The term is frequently associated with state spying on potential or actual enemies for military purposes. However, there are many types of espionage. Industrial espionage, for example, involves spying on civilians and their respective business or corporate interests.

Cryptography, or cryptology (from Ancient Greek: κρυπτός, romanized: kryptós "hidden, secret"; and γράφειν graphein, "to write", or -λογία -logia, "study", respectively), is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others. Core concepts related to information security (data confidentiality, data integrity, authentication and non-repudiation) are also central to cryptography. Practical applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords and military communications.

Cryptography prior to the modern age was effectively synonymous with encryption, converting readable information (plaintext) to unintelligible nonsense text (ciphertext), which can only be read by reversing the process (decryption). The sender of an encrypted (coded) message shares the decryption (decoding) technique only with the intended recipients to preclude access from adversaries. The cryptography literature often uses the names "Alice" (or "A") for the sender, "Bob" (or "B") for the intended recipient, and "Eve" (or "E") for the eavesdropping adversary. Since the development of rotor cipher machines in World War I and the advent of computers in World War II, cryptography methods have become increasingly complex and their applications more varied.

In computer security, vulnerabilities are flaws or weaknesses in a system's design, implementation, or management that can be exploited by a malicious actor to compromise its security.

Despite a system administrator's best efforts to achieve complete correctness, virtually all hardware and software contain bugs where the system does not behave as expected. If the bug could enable an attacker to compromise the confidentiality, integrity, or availability of system resources, it can be considered a vulnerability. Insecure software development practices as well as design factors such as complexity can increase the burden of vulnerabilities.

Information assurance (IA) is the practice of assuring information and managing risks related to the use, processing, storage, and transmission of information. Information assurance includes protection of the integrity, availability, authenticity, non-repudiation and confidentiality of user data. IA encompasses both digital protections and physical techniques. These methods apply to data in transit, both physical and electronic forms, as well as data at rest. IA is best thought of as a superset of information security (i.e. umbrella term), and as the business outcome of information risk management.

Primary care ethics is the study of the everyday decisions that primary care clinicians make, such as: how long to spend with a particular patient, how to reconcile their own values and those of their patients, when and where to refer or investigate, how to respect confidentiality when dealing with patients, relatives and third parties. All these decisions involve values as well as facts and are therefore ethical issues. These issues may also involve other workers in primary healthcare, such as receptionists and managers.

Primary care ethics is not a discipline; it is a notional field of study which is simultaneously an aspect of primary health care and applied ethics. De Zulueta argues that primary care ethics has ‘a definitive place on the ‘bioethics map’, represented by a substantial body of empirical research, literary texts and critical discourse (2, 9, 10). The substantial body of research referred to by De Zulueta (9) has a tendency to be issue-specific, such as to do with rationing(11), confidentiality, medical reports, or relationships with relatives.

In the context of information security, social engineering is the use of psychological influence of people into performing actions or divulging confidential information. It has also been more broadly defined as "any act that influences a person to take an action that may or may not be in their best interests." A type of confidence trick for the purpose of information gathering, fraud, or system access, it differs from a traditional "con" in the sense that it is often one of many steps in a more complex fraud scheme.

Social engineering attacks have been increasing in intensity and number, prompting research into novel detection techniques and cybersecurity educational programs.

Banking secrecy, alternatively known as financial privacy, banking discretion, or bank safety, is a conditional agreement between a bank and its clients that all foregoing activities remain secure, confidential, and private. Most often associated with banking in Switzerland, banking secrecy is prevalent in Luxembourg, Monaco, Hong Kong, Singapore, Ireland, and Lebanon, among other off-shore banking institutions.

Otherwise known as bank–client confidentiality or banker–client privilege, the practice was started by Italian merchants during the 1600s near Northern Italy (a region that would become the Italian-speaking region of Switzerland). Geneva bankers established secrecy socially and through civil law in the French-speaking region during the 1700s. Swiss banking secrecy was first codified with the Banking Act of 1934, thus making it a crime to disclose client information to third parties without a client's consent. The law, coupled with a stable Swiss currency and international neutrality, prompted large capital flight to private Swiss accounts. During the 1940s, numbered bank accounts were introduced creating an enduring principle of bank secrecy that continues to be considered one of the main aspects of private banking globally. Advances in financial cryptography (via public-key cryptography) could make it possible to use anonymous electronic money and anonymous digital bearer certificates for financial privacy and anonymous Internet banking, given enabling institutions and secure computer systems.

Patient advocacy is a process in health care concerned with advocacy for patients, survivors, and caregivers. The patient advocate may be an individual or an organization, concerned with healthcare standards or with one specific group of disorders. The terms patient advocate and patient advocacy can refer both to individual advocates providing services that organizations also provide, and to organizations whose functions extend to individual patients. Some patient advocates are independent (with no conflict-of-loyalty issues) and some work for the organizations that are directly responsible for the patient's care.

Typical advocacy activities are the following: safeguarding patients from errors, incompetence and misconduct; patient rights, matters of privacy, confidentiality or informed consent, patient representation, awareness-building, support and education of patients, survivors and their carers.
