These new uses of clinical data potentially affect healthcare because the patient physician relationship depends on very high levels of trust. To operate effectively physicians need complete and accurate information about the patient. Data mining especially when it draws information from multiple sources poses special problems.

For example, hospitals and physicians are commonly required to report certain information for a variety of purposes from census to public health to finance. Compilations of this data have been released to industry and researchers.

Because such compilations do not contain the patient name, address, telephone number, or social security number, they qualify as de-identified and, therefore, appear to pose little risk to patient privacy.

But by cross linking this data with publicly available databases, processes such as data mining may associate an individual with specific diagnoses. Recent laws and regulations such as HIPAA provide patients with legal rights regarding their personally identifiable healthcare information and establish obligations for healthcare organizations to protect and restrict its use or disclosure. Data miners should have a basic understanding of healthcare information privacy and security in order to reduce risk of harm to individuals, their organization or themselves.

Privacy in Healthcare InformationThe term "privacy" bears many meanings depending on the context of use. Common meanings include being able to control release of information about one's self to others and being free from intrusion or disturbance in one's personal life.

To receive healthcare one must reveal information that is very personal and often sensitive. We control the privacy of our healthcare information by what we reveal to our physicians and others in the healthcare delivery system. Once we share personal information with our caregivers, we no longer have control over its privacy. In this sense, the term "privacy" overlaps with "confidentiality" or the requirement to protect information received from patients from unauthorized access and disclosure.

Thus, ethics, laws and regulations provide patients with certain rights and impose obligations on the healthcare industry that should keep patient health information from being disclosed to those who are not authorized to see it.

Security in Healthcare InformationThe Internet has resulted in recognition that information technology security is of major importance to our society.

This concern seems relatively new in healthcare, but information technology security is a well established domain. A large body of knowledge exists that can be applied to protect healthcare information. Threats, Vulnerabilities, Control Measures And Information AssuranceNumerous [6] threats exist to computer systems and the information they contain originating from within and outside organizations. Some common threats include malicious code such as viruses, Trojan horses, or worms.

Malicious code often takes advantage of vulnerabilities in operating system software but depends, too, upon organizational weaknesses such as the failure to deploy, update or train workers in the use of antivirus software. Malicious code may enable denial of service attacks, impersonation, information theft and other intrusions. Attacks by famous malicious code such as the Melissa or Love bug viruses highlight the threat of "hackers", outsiders with intent to harm specific organizations or network operations in general.

Insiders with privileged access to network operations and a grudge against their employer actually wreak the most harm to say nothing of ill trained workers unintentionally making mistakes.

Specifically included are: quality assessment and improvement activities, outcomes evaluation, development of clinical guidelines, population-based activities relating to improving health or reducing health care costs, protocol development, case management and care coordination, contacting of health care providers and patients with information about treatment alternatives; and related functions that do not include treatment, reviewing the competence or qualifications of health care professionals, evaluating practitioner, provider performance and health plan performance, conducting training programs in which students, trainees, or practitioners in areas of health care learn under supervision to practice or improve their skills.

Numerous organizations desire access to this data to apply techniques of knowledge discovery. Privacy concerns exist for information disclosed without illegal intrusion or theft. A person's identity can be derived from what appears to be innocent information by linking it to other available data. Concerns also exist that such information may be used in ways other than promised at the time of collection. Statistical databases containing individually identifiable information including: conceptual, query restriction, data perturbation, and output perturbation approaches The conceptual model has not been implemented in an on-line environment and the others involve considerable complexity and cost and may obscure medical knowledge Query restriction approachFive methods have been developed to restrict queries: 1.

Query-Set-Size Control: A method that returns a result only if its size is sufficient to reduce the chances of identification, 2. Query-Set-Overlap Control: A method that limits the number of overlapping entities among successive queries of a given user. Auditing A method that creates up-to-date logs of all queries made by each user and constantly checks for possible compromise when anew query is issued. Cell Suppression :A method that suppresses cells that might cause confidential information to be disclosed from being released.

Partitioning: A method that clusters individual entities into a number of mutually exclusive subsets thus preventing any subset from containing precisely one individual.

InputThis approach alters the data before permitting access to users. Users do not have access to the original data. OutputThis approach permits use of the original data, but modifies or renders the output incomplete. Techniques of output perturbation include processing only a random sample of the data in the query, adding or subtracting a random value that will not alter the statistical difference from the result, and rounding up or down to the nearest multiple of a certain base.

Specific ApproachesRendering data anonymous assures freedom from identification, surveillance or intrusion for the subjects of medical research or secondary data analysis while allowing data to be shared freely among investigators A number of techniques exemplifying or combining the general approaches described above have been advocated to help address this issue, including: 1.

Data aggregation 2. Data de-identification 3. Binning 4. Pseudonymisation 5. Mediated access Data AggregationProviding access only to aggregate data while prohibiting access to records containing data on an individual constitutes one approach commonly advocated to reduce risks to privacy. Although this approach does protect privacy, it critically limits medical research. Clinical research requires prospectively capturing and analyzing data elements associated with individual patients.

Outliers are often a major focus of interest. Aggregate data does not support such efforts. Deidentified health information may be used and disclosed without authorization. The HIPAA Privacy Standard considers information to have been deidentified by the use of either a statistical verification of deidentification or by removing 18 explicit elements of data. Such data may be used or disclosed without restriction.

The details of these approaches are described in the pamphlet, 3. Protecting: A variety of approaches for this issue have been published including successful implementation of policies, procedures, techniques and toolkits that meet academic medical center needs and comply with the Privacy Standard [1], [2].

Pseudonymisation: This technique involves replacing the true identities of the individuals and organizations while retaining a linkage for the data acquired over time that permits re-identification under controlled circumstances [6].

A trusted third party and process is involved. The trusted third party and process must be strictly independent, adhere to a code of conduct with principles of openness and transparency, have project-specific privacy and security policies and maintain documentation of operating, reporting and auditing systems [4]. Mediated accessMediated access puts policy, procedure and technology between the user and the data and, thus, illustrates a general point that all medical investigators should bear in mind: sound health information privacy and security programs include a range of controls.

The security officer decides to approve, edit, or reject the information. An associated logging subsystem provides both an audit trail for all information that enters or leaves the domain, and provides input to the security officer to aid in evolving the rule set, and increasing the effectiveness of the system.

New efforts in "privacy technology" attempt to protect individual privacy. Threats to Homeland Security have made considerable funding available to investigate this topic in order to support bio-terrorism surveillance and protect individual privacy.

Techniques have been reported for embedding encrypted digital watermarking and patient identifiers in medical images to protect privacy during use and transmission. Data mining investigators have begun encouraging their colleagues to take a research interest in issues related to protecting the privacy and security of personal information.

The techniques of data mining have been used to address the issue of auditing access and use of data as well as for testing devices for intrusion detection and access control.

Commercial products exist that automatically correlate and compare suspicious information gathered from different points in computer systems, draw conclusions, and act on potential attacks and security violations [10]. Future laws and regulations are likely to increase penalties for inappropriate use or disclosure. While much attention has been given to research, organizations should implement the same general processes to support analyses done for the purpose of healthcare operations as for research.

Data integrity

Metrics details. Big data is a term used for very large data sets that have more varied and complex structure. These characteristics usually correlate with additional difficulties in storing, analyzing and applying further procedures or extracting results. Big data analytics is the term used to describe the process of researching massive amounts of complex data in order to reveal hidden patterns or identify secret correlations. However, there is an obvious contradiction between the security and privacy of big data and the widespread use of big data. This paper focuses on privacy and security concerns in big data, differentiates between privacy and security and privacy requirements in big data. This paper covers uses of privacy by taking existing methods such as HybrEx, k-anonymity, T-closeness and L-diversity and its implementation in business.

The necessity to improve security in a multi-cloud environment has become very urgent in recent years. Although in this topic, many methods using the message authentication code had been realized but, the results of these methods are unsatisfactory and heavy to apply, which, is why the security problem remains unresolved in this environment. This article proposes a new model that provides authentication and data integrity in a distributed and interoperable environment. For that in this paper, the authors first analyze some security models used in a large and distributed environment, and then, we introduce a new model to solve security issues in this environment. Our approach consists of three steps, the first step, was to propose a private virtual network to secure the data in transit.

Big data security challenges and strategies


Privacy-Preserving Data Mining pp Cite as. In recent years, privacy-preserving data mining has been studied extensively, because of the wide proliferation of sensitive information on the internet. A number of algorithmic techniques have been designed for privacy-preserving data mining. In this paper, we provide a review of the state-of-the-art methods for privacy. We discuss methods for randomization, k -anonymization, and distributed privacy-preserving data mining.

NCBI Bookshelf. Earlier chapters introduced the Institute of Medicine IOM committee's conceptualization of health database organizations HDOs , outlined their presumed benefits, listed potential users and uses, and examined issues related to the disclosure of descriptive and evaluative data on health care providers institutions, agencies, practitioners, and similar entities. This chapter examines issues related to information about individuals or patients—specifically, what this committee refers to as person-identified or person-identifiable data. It defines privacy, confidentiality, and security in the context of health-related information and outlines the concerns that health experts, legal authorities, information technology specialists, and society at large have about erosions in the protections accorded such information. It pays particular attention to the status that might be accorded such data when held by HDOs. Existing ethical, legal, and other approaches to protecting confidentiality and privacy of personal health data offer some safeguards, but major gaps and limitations remain. The recommendations at the end of this chapter are intended to strengthen current protections for confidentiality and privacy of health-related data, particularly for information acquired by HDOs.

Белоснежные волосы аккуратно зачесаны набок, в центре лба темно-красный рубец, тянущийся к правому глазу. Ничего себе маленькая шишка, - подумал Беккер, вспомнив слова лейтенанта. Посмотрел на пальцы старика - никакого золотого кольца.

Но когда он начал подниматься на следующую ступеньку, не выпуская Сьюзан из рук, произошло нечто неожиданное. За спиной у него послышался какой-то звук. Он замер, чувствуя мощный прилив адреналина.

По-видимому, Танкадо считал, что два эти события чем-то различались между. Выражение лица Фонтейна не изменилось. Но надежда быстро улетучивалась. Похоже, нужно было проанализировать политический фон, на котором разворачивались эти события, сравнить их и перевести это сопоставление в магическое число… и все это за пять минут. ГЛАВА 124 - Атаке подвергся последний щит.

Она узнала этот запах, запах плавящегося кремния, запах смертельного яда. Отступив в кабинет Стратмора, Сьюзан почувствовала, что начинает терять сознание. В горле нестерпимо горело. Все вокруг светилось ярко-красными огнями. Шифровалка умирала.

Он утверждал, что стремление граждан к неприкосновенности частной переписки обернется для Америки большими неприятностями. Он доказывал, что кто-то должен присматривать за обществом, что взлом шифров агентством - вынужденная необходимость, залог мира. Но общественные организации типа Фонда электронных границ считали. И развязали против Стратмора непримиримую войну.

Мысли его перенеслись назад, в детство. Родители… Сьюзан. О Боже… Сьюзан. Впервые с детских лет Беккер начал молиться. Он молился не об избавлении от смерти - в чудеса он не верил; он молился о том, чтобы женщина, от которой был так далеко, нашла в себе силы, чтобы ни на мгновение не усомнилась в его любви.
