Access Control Mechanisms Protect Sensitive Information From Unauthorized Users

Privacy in this era is threatened by the growth in technology with capacity that is enhanced for surveillance, storage, communication as well as computation. Moreover, the increased value of this information in decision making is one of the insidious threats. For this reason, information and its privacy are actually threatened and less privacy is assured.

In the past decade, a number of PPDM techniques have been proposed to facilitate users in performing data mining tasks in privacy-sensitive environments. Agrawal and Srikant [3], as well as Lindell and Pinkas [63], were the first to introduce the notion of privacy-preserving under data mining applications. Existing PPDM techniques can be classified into two broad categories: data perturbation and data distribution. Data Perturbation Methods: With these methods, values of individual data records are perturbed by adding random noise in such a way that the distribution of the perturbed data look very deferent from that of the actual data. After such a transformation, the perturbed data is sent to the Miner to perform the desired data mining tasks. Agrawal and Srikant [3] proposed the first data perturbation technique that could be used to build a decision-tree classifier. A number of randomization-based methods were later proposed [6, 33, 34, 73, 104]. Data perturbation techniques are not, however, applicable to semantically- secure encrypted data. They also fail to produce accurate data mining results due to the addition of statistical noises to the data. Data Distribution Methods: These methods assume that the dataset is partitioned eitherhorizontallyorverticallyanddistributedacrossdifferentparties. The parties

Care homes as part of primary care team in health and social care setting like other organisations will need to record residents’ well being, progress of health condition etc. on a daily basis, and without exemption they need to be in accordance with legislation and policy to ensure the quality, accuracy and safety of the records.

The analysis of the problem should take a day. At the analysis stage we determine the solution. The solution has been identified as the installation of the access control system. At this stage the system parts are identified; they include input, output, communication devices, power supplies, detection devices, intelligent panels, card readers, lock hardware, the actions and the response of the system in case of violation of the input requirements or failure of the system.

When necessary, care homes or hospitals are required to ask a local authority if they can deprive a person of their liberty. This is known as Standard Authorization. There are six assessments which have to take place before the Standard Authorization can be given. These assessments are set to determine a number of relevant factors. The assessments include an age assessment to confirm if the individual is 16 or over. A No refusals assessment which is to establish whether an authorisation would conflict with a pre-existing authority for decision-making for the individual, such as an advance decision to refuse treatment under the legislation 2005. A mental capacity assessment, this assessment establishes whether the individual lacks the capacity to decide whether or not they should be admitted to a hospital or care home to receive care. The mental health assessment which determines if the individual in question has a mental disorder within the list of the Mental Health Act 1983. The purpose of this assessment is to ensure that the individual is medically diagnosed as being of “unsound mind”. The eligibility assessment that relates specifically to the relevant individual’s status, or potential status, under the Mental Health Act. An individual is considered to be eligible unless they

In a health and social care setting protecting sensitive information is paramount to good care practice. It is the duty of employers to ensure that their policies and procedures adequately cover Data protection and meet the Care Quality Commission. The laws that should be followed are the Data Protection Act 1998, and the Freedom of information act 2000. The Independent Commissioners Office (I.C.O) deals primarily with breaches of information should they occur. Below is a description of the Data protection act and the Freedom of Information act. It is also the duty of employers to ensure that employer’s policies and procedures adequately cover Data protection.

Separation of duties- Which the practice of requiring the process should be divided between two or more individuals. For example, in large organization the Chief Information Security Office (CISO) cannot be the same as security manager.

Implementing physical security as an access control plan takes a great effort of planning. Physical security is the protection and controlled access of personnel, the environment they operate in, which includes the hardware and what it contains, as well as the rooms and buildings they are located in. Physical security has three indispensable parts: access to control, observation, and testing. Obstacles should be set for potential aggressors and physical areas should be bolstered against anything causing delays, attacks or natural disasters. Such measures can include proper fencing, locks, control access cards, biometrics that control systems and fire proofing structures. Physical areas should be checked using observation cameras and for

Data Confidentiality is not enough for secure data transmission in the military environment. Flexible and Fine-Grained access control is also required to make data more secure for the military environment. The information about the particular organization is required to be protected. In this case, access control of sensitive data is done by allowing users to access the data based on their roles. For example, the information about the colleges will be viewed based on their roles such as students, faculty, and higher level

Role based access control is an ideology through which access to systems is restricted based on authority given. It is used by organizations with a relatively large number of employees ranging from five hundred to one thousand and above (Sieunarine & University of Oxford, 2011). This is implemented through the mandatory access control or through the discretionary access control. These are the only two ways through which role based access control can be implemented.

As soon as this process is complete, your document or email will be encrypted with a strong key of 2048bit in key size. The email or document can be saved off/lost or stolen but will remain protected regardless if it falls in the wrong hands.

As the use of computers, databases, and technology in general, security has grown to be a powerful tool that has to be used. The threat of outside sources intruding and exploiting crucial information is a threat that is present on a daily basis. As a part of creating and implementing a security policy, a user must consider access control. Access Control is a security tool that is used to control who can use or gain access to the protected technology. Access control security includes two levels; logical and physical. Though database intrusions can happen at any moment, access control provides another security barrier that is needed.

We suggest a Profile-based personalized web search framework UPS (User customizable Privacy-preserving Search), for each query ac-cording to user specified privacy requirements profile is generated. For hierarchical user pro-file we trust two conflicting metrics, namely personalization utility and privacy risk, with its NP-hardness proved we formulate the problem of Profile-based personalized search as Risk Profile Generalization.
