The Parkerian hexad is a set of six elements of information security proposed by Donn B. Parker in 1998. The Parkerian hexad adds three additional attributes to the three classic security attributes of the CIA triad (confidentiality, integrity, availability).

52-674: The Parkerian Hexad attributes are the following: These attributes of information are atomic in that they are not broken down into further constituents; they are non-overlapping in that they refer to unique aspects of information. Any information security breach can be described as affecting one or more of these fundamental attributes of information. Confidentiality refers to limits on who can get what kind of information. For example, executives concerned about protecting their enterprise's strategic plans from competitors; individuals are concerned about unauthorized access to their financial records. Integrity refers to being correct or consistent with

104-418: A health care professional to share their information with another healthcare professional, even one giving them care—but are advised, where appropriate, about the dangers of this course of action, due to possible drug interactions. However, in a few limited instances, a healthcare worker can share personal information without consent if it is in the public interest. These instances are set out in guidance from

156-781: A 'Sunshine in Litigation' law that limits confidentiality from concealing public hazards. Washington state, Texas, Arkansas, and Louisiana have laws limiting confidentiality as well, although judicial interpretation has weakened the application of these types of laws. In the U.S. Congress, a similar federal Sunshine in Litigation Act has been proposed but not passed in 2009, 2011, 2014, and 2015.

208-595: A client may vary by profession. Such experts can be such as CPAs , Actuaries , medical doctors , or engineers . These experts may be disclosed or undisclosed to the Court. In the United States disclosed Expert witnesses may not be covered under the Kovel Standard, depending on the Court and the nature of their work, and their involvement in the legal advice process. Although there are minor variations,

260-572: A client was about to commit murder or assault. The Supreme Court of California promptly amended the California Rules of Professional Conduct to conform to the new exception in the revised statute. Recent legislation in the UK curtails the confidentiality professionals like lawyers and accountants can maintain at the expense of the state. Accountants, for example, are required to disclose to the state any suspicions of fraudulent accounting and, even,

312-416: A disk crash or denial-of-service attacks both cause a breach of availability. Any delay that exceeds the expected service levels for a system can be described as a breach of availability. Authenticity refers to the veracity of the claim of origin or authorship of the information. For example, one method for verifying the authorship of a hand written document is to compare the handwriting characteristics of

364-440: A distrustful client might hide a relevant fact he thinks is incriminating, but that a skilled lawyer could turn to the client's advantage (for example, by raising affirmative defenses like self-defense). However, most jurisdictions have exceptions for situations where the lawyer has reason to believe that the client may kill or seriously injure someone, may cause substantial injury to the financial interest or property of another, or

416-440: A federal proceeding or to a federal office or agency do not act as a waiver of the privilege if the holder of the privilege "took reasonable steps to prevent disclosure" in the first place and "promptly took reasonable steps to rectify the error." Parties cannot merely state that they took "reasonable steps to prevent disclosure," instead they must give the court a detailed account of the procedures they took. Further, merely sending

468-431: A graph could be described as a breach of utility if the substitution made it more difficult to interpret the data. Utility is often confused with availability because breaches such as those described in these examples may also require time to work around the change in data format or presentation. However, the concept of usefulness is distinct from that of availability. Confidentiality Confidentiality involves

520-400: A joint defense or strategy has been decided upon and undertaken by the parties and their respective counsel." An attorney speaking publicly in regard to a client's personal business and private affairs can be reprimanded by the bar or disbarred, regardless of the fact that he or she may be no longer representing the client. Discussing a client's or past client's criminal history, or otherwise,

572-408: A lawyer effectively waives rights to confidentiality. This is justified on grounds of procedural fairness—a lawyer unable to reveal information relating to the retainer would be unable to defend themselves against such action. Another case is for the probate of a last will and testament . Previously confidential communications between the lawyer and testator may be disclosed in order to prove that

SECTION 10

624-415: A patient's consent to share personal confidential information is assumed. When personal confidential information is shared between healthcare workers, consent is taken as implied. If a patient doesn't want a healthcare worker to share confidential health information, they need to make this clear and discuss the matter with healthcare staff. Patients have the right, in most situations, to refuse permission for

676-424: A set of rules or a promise usually executed through confidentiality agreements that limits the access to or places restrictions on the distribution of certain types of information . By law, lawyers are often required to keep confidential anything on the representation of a client. The duty of confidentiality is much broader than the attorney–client evidentiary privilege , which only covers communications between

728-425: A will represented the intent of the now deceased decedent . In many instances, the will, codicil , or other parts of the estate plan require explanation or interpretation through other proof (extrinsic evidence), such as the attorney's file notes or correspondence from the client. In certain cases, the client may desire or consent to revelation of personal or family secrets only after his or her death; for example,

780-488: Is about to, provide the patient directly with healthcare to make sure they get the best possible treatment. They only share information that is relevant to their care in that instance, and with consent. There are two ways to give consent: explicit consent or implied consent . Explicit consent is when a patient clearly communicates to a healthcare worker, verbally or in writing or in some other way, that relevant confidential information can be shared. Implied consent means that

832-470: Is also an attorney; some or all of the resulting communications may be privileged provided that all the requirements for the attorney–client privilege are met. The mere fact that the practitioner is an attorney will not create a valid attorney–client privilege with respect to a communication. For example, if the practitioner provides business or accounting advice rather than legal advice attorney–client privilege might not be established. Under federal tax law in

884-694: Is based in law, in the NHS Constitution, and in key NHS rules and procedures. It is also outlined in every NHS employee's contract of employment and in professional standards set by regulatory bodies. The National AIDS Trust's Confidentiality in the NHS: Your Information, Your Rights outlines these rights. All registered healthcare professionals must abide by these standards and if they are found to have breached confidentiality, they can face disciplinary action. A healthcare worker shares confidential information with someone else who is, or

936-471: Is determined by the use of negative and positive freedom. Some legal jurisdictions recognise a category of commercial confidentiality whereby a business may withhold information on the basis of perceived harm to "commercial interests". For example, Coca-Cola 's main syrup formula remains a trade secret . Confidentiality agreements that "seal" litigation settlements are not uncommon, but this can leave regulators and society ignorant of public hazards. In

988-452: Is the common law doctrine of legal professional privilege in the United States. Attorney–client privilege is "[a] client's right to refuse to disclose and to prevent any other person from disclosing confidential communications between the client and the attorney." The attorney–client privilege is one of the oldest privileges for confidential communications. The United States Supreme Court has stated that by assuring confidentiality ,

1040-469: Is to succeed. First, the information itself, in the words of Lord Greene, M.R. in the Saltman case on page 215, must "have the necessary quality of confidence about it." Secondly, that information must have been imparted in circumstances importing an obligation of confidence. Thirdly, there must be an unauthorised use of that information to the detriment of the party communicating it. The 1896 case featuring

1092-448: Is using (or seeking to use) the lawyer's services to perpetrate a crime or fraud. In such situations the lawyer has the discretion, but not the obligation, to disclose information designed to prevent the planned action. Most states have a version of this discretionary disclosure rule under Rules of Professional Conduct, Rule 1.6 (or its equivalent). A few jurisdictions have made this traditionally discretionary duty mandatory. For example, see

SECTION 20

1144-479: Is viewed as a breach of confidentiality. The attorney–client privilege is separate from and should not be confused with the work-product doctrine . When an attorney is not acting primarily as an attorney but, for instance, as a business advisor, member of the Board of Directors, or in another non-legal role, then the privilege generally does not apply. The privilege protects the confidential communication, and not

1196-519: The good clinical practice inspections in accordance with applicable national and international requirements. A typical patient declaration might read: I have been informed of the benefit that I gain from the protection and the rights granted by the European Union Data Protection Directive and other national laws on the protection of my personal data. I agree that the representatives of the sponsor or possibly

1248-510: The therapeutic alliance , as it promotes an environment of trust. There are important exceptions to confidentiality, namely where it conflicts with the clinician's duty to warn or duty to protect . This includes instances of suicidal behavior or homicidal plans, child abuse , elder abuse and dependent adult abuse . Information shared by a client with a therapist is considered as privileged communication , however in certain cases and based on certain provinces and states they are negated, it

1300-571: The General Medical Council, which is the regulatory body for doctors. Sometimes the healthcare worker has to provide the information – if required by law or in response to a court order. The National AIDS Trust has written a guide for people living with HIV to confidentiality in the NHS. The ethical principle of confidentiality requires that information shared by a client with a therapist isn't shared without consent, and that

1352-492: The New Jersey and Virginia Rules of Professional Conduct, Rule 1.6. In some jurisdictions, the lawyer must try to convince the client to conform his or her conduct to the boundaries of the law before disclosing any otherwise confidential information. These exceptions generally do not cover crimes that have already occurred, even in extreme cases where murderers have confessed the location of missing bodies to their lawyers but

1404-501: The U.S. state of Washington, for example, journalists discovered that about two dozen medical malpractice cases had been improperly sealed by judges, leading to improperly weak discipline by the state Department of Health. In the 1990s and early 2000s, the Catholic sexual abuse scandal involved a number of confidentiality agreements with victims. Some states have passed laws that limit confidentiality. For example, in 1990 Florida passed

1456-476: The United States, for communications on or after July 22, 1998, there is a limited federally authorized accountant–client privilege that may apply to certain communications with non-attorneys. If a case arises in the federal court system, the federal court will apply Rule 501 of the Federal Rules of Evidence to determine whether to apply the privilege law of the relevant state or federal common law. If

1508-399: The attorney and the client. Both the privilege and the duty serve the purpose of encouraging clients to speak frankly about their cases. This way, lawyers can carry out their duty to provide clients with zealous representation. Otherwise, the opposing side may be able to surprise the lawyer in court with something he did not know about his client, which may weaken the client's position. Also,

1560-460: The case is brought to the federal court under diversity jurisdiction , the law of the relevant state will be used to apply the privilege. If the case involves a federal question , the federal court will apply the federal common law of attorney–client privilege; however, Rule 501 grants flexibility to the federal courts, allowing them to construe the privilege "in light of experience and reason". FRE 502(b) provides that inadvertent disclosures during

1612-517: The decryption key: that would be a breach of utility. The data would be confidential, controlled, integral, authentic, and available–they just wouldn't be useful in that form. Similarly, conversion of salary data from one currency into an inappropriate currency would be a breach of utility, as would the storage of data in a format inappropriate for a specific computer architecture; e.g., EBCDIC instead of ASCII or 9-track magnetic tape instead of DVD-ROM. A tabular representation of data substituted for

1664-603: The doctor. Confidentiality is commonly applied to conversations between doctors and patients. Legal protections prevent physicians from revealing certain discussions with patients, even under oath in court. This physician-patient privilege only applies to secrets shared between physician and patient during the course of providing medical care. The rule dates back to at least the Hippocratic Oath , which reads in part: Whatever, in connection with my professional service, or not in connection with it, I see or hear, in

1716-429: The document to a sampling of others which have already been verified. For electronic information, a digital signature could be used to verify the authorship of a digital document using public-key cryptography (could also be used to verify the integrity of the document). Possession or control: Suppose a thief were to steal a sealed envelope containing a bank debit card and its personal identification number. Even if

1768-432: The elements necessary to establish the attorney–client privilege generally are: There are a number of exceptions to the privilege in most jurisdictions, chief among them: A corollary to the attorney–client privilege is the joint defense privilege , which is also called the common interest rule . The common interest rule "serves to protect the confidentiality of communications passing from one party to another party where

1820-399: The health authorities can have access to my medical records. My participation in the study will be treated as confidential. I will not be referred to by my name in any report of the study. My identity will not be disclosed to any person, except for the purposes described above and in the event of a medical emergency or if required by the law. My data will be processed electronically to determine

1872-399: The intended state of information. Any unauthorized modification of data, whether deliberate or accidental, is a breach of data integrity . For example, data stored on disk are expected to be stable – they are not supposed to be changed at random by problems with a disk controller . Similarly, application programs are supposed to record information correctly and not introduce deviations from

1924-579: The intended values. From Donn Parker: "My definition of information integrity comes from the dictionaries. Integrity means that the information is whole, sound, and unimpaired (not necessarily correct). It means nothing is missing from the information it is complete and in intended good order." The author's statement comes close in saying that the information is in a correct...state. Information may be incorrect or not authentic but have integrity or correct and authentic but lacking in integrity. Availability means having timely access to information. For example,

1976-529: The knowledge of the patient's parents. Many states in the U.S. have laws governing parental notification in underage abortion. Confidentiality can be protected in medical research via certificates of confidentiality . Due to the EU Directive 2001/20/EC , inspectors appointed by the Member States have to maintain confidentiality whenever they gain access to confidential information as a result of

2028-468: The law. He must let the truth be told." The crime–fraud exception also does require that the crime or fraud discussed between client and attorney be carried out to be triggered. U.S. courts have not yet conclusively ruled how little knowledge an attorney can have of the underlying crime or fraud before the privilege detaches and the attorney's communications or requisite testimony become admissible. Lawyers may disclose confidential information relating to

2080-454: The legitimate use of tax saving schemes if those schemes are not already known to the tax authorities. The "three traditional requirements of the cause of action for breach of confidence" were identified by Megarry J in Coco v A N Clark (Engineers) Ltd (1968) in the following terms: In my judgment, three elements are normally required if, apart from contract, a case of breach of confidence

2132-504: The life of men, which ought not to be spoken of abroad, I will not divulge, as reckoning that all such should be kept secret. Traditionally, medical ethics has viewed the duty of confidentiality as a relatively non-negotiable tenet of medical practice. Confidentiality is standard in the United States by HIPAA laws, specifically the Privacy Rule, and various state laws, some more rigorous than HIPAA. However, numerous exceptions to

2184-614: The outcome of this study, and to provide it to the health authorities. My data may be transferred to other countries (such as the USA). For these purposes the sponsor has to protect my personal information even in countries whose data privacy laws are less strict than those of this country. In the United Kingdom information about an individual's HIV status is kept confidential within the National Health Service . This

2236-710: The police are still looking for those bodies. The U.S. Supreme Court and many state supreme courts have affirmed the right of a lawyer to withhold information in such situations. Otherwise, it would be impossible for any criminal defendant to obtain a zealous defense. California is famous for having one of the strongest duties of confidentiality in the world; its lawyers must protect client confidences at "every peril to himself [or herself]" under former California Business and Professions Code section 6068(e). Until an amendment in 2004 (which turned subsection (e) into subsection (e)(1) and added subsection (e)(2) to section 6068), California lawyers were not even permitted to disclose that

2288-462: The privilege encourages clients to make "full and frank" disclosures to their attorneys, who are then better able to provide candid advice and effective representation. With respect to experts that are hired by the attorneys, the attorney-client privilege is referred to as a Kovel standard based on the case of United States v. Kovel, 296 F.2d 918 (2d Cir. 1961) or broadly a Kovel Agreement . Experts hired by attorneys to assist in representation of

2340-420: The privilege may apply depending on the situation being adjudicated. The crime–fraud exception can render the privilege moot when communications between an attorney and client are themselves used to further a crime, tort , or fraud. In Clark v. United States , the U.S. Supreme Court stated that "A client who consults an attorney for advice that will serve him in the commission of a fraud will have no help from

2392-476: The retainer where they are reasonably seeking to collect payment for services rendered. This is justified on policy grounds. If lawyers were unable to disclose such information, many would undertake legal work only where payment is made in advance. This would arguably adversely affect the public's access to justice. Lawyers may also breach the duty where they are defending themselves against disciplinary or legal proceedings. A client who initiates proceedings against

2444-427: The royal accoucheur Dr William Smoult Playfair showed the difference between lay and medical views. Playfair was consulted by Linda Kitson; he ascertained that she had been pregnant while separated from her husband. He informed his wife, a relative of Kitson's, in order that she protect herself and their daughters from moral contagion. Kitson sued, and the case gained public notoriety, with huge damages awarded against

2496-489: The rules have been carved out over the years. For example, many American states require physicians to report gunshot wounds to the police and impaired drivers to the Department of Motor Vehicles. Confidentiality is also challenged in cases involving the diagnosis of a sexually transmitted disease in a patient who refuses to reveal the diagnosis to a spouse, and in the termination of a pregnancy in an underage patient, without

2548-402: The sharing of information would be guided by ETHIC Model: Examining professional values, after thinking about ethical standards of the certifying association, hypothesize about different courses of action and possible consequences, identifying how it and to whom will it be beneficial per professional standards, and after consulting with supervisor and colleagues. Confidentiality principle bolsters

2600-405: The thief did not open that envelope, it's reasonable for the victim to be concerned that the thief could do so at any time. That situation illustrates a loss of control or possession of information but does not involve the breach of confidentiality. Utility means usefulness. For example, suppose someone encrypted data on disk to prevent unauthorized access or undetected modifications–and then lost

2652-457: The underlying information. For instance, if a client has previously disclosed confidential information to a third party who is not an attorney, and then gives the same information to an attorney, the attorney–client privilege will still protect the communication to the attorney, but will not protect the communication with the third party. The privilege may be waived if the confidential communications are disclosed to third parties. Other limits to

SECTION 50

2704-542: The will may leave a legacy to a paramour or a natural child . Courts have occasionally revoked the privilege after the death of the client if it is deemed that doing so serves the client's intent, such as in the case of resolving testamentary disputes among heirs. In the United States, communications between accountants and their clients are usually not privileged. A person who is worried about accusations of questionable accounting, such as tax evasion , may decide to work only with an attorney or only with an accountant who
