Essay On Searchable Encryption

With the enthusiasm for health information technology, potential risks and problems associated with electronic health records have received far less attention. Three fundamental security goals are essential to EHR systems: confidentiality, integrity and availability (Haas e26). Patients lose the protection of implied trust domain of medical institutions due to their medical record maintenance performed by non-medical enterprises (e27). Depending on the paradigm, enabling access to an increased number of users poses threats to security and privacy.

A company allows its staffs in the same groupor department to store and share files in the cloud. By utilizing the cloud, the staffs can be completely released from the troublesome local data storage and maintenance.However, it also poses a significant risk to the confidentialityof those stored files. Specifically, the cloud serversmanaged by cloud providers are not fully trusted by userswhile the data files stored in the cloud may be sensitive andconfidential, such as business plans. To preserve dataprivacy, a basic solution is to encrypt data files, and thenupload the encrypted data into the cloud. Unfortunately,designing an efficient and secure data sharing scheme forgroups in the cloud is not an easy task due to the followingchallenging issues.First, identity privacy is one of the most significantobstacles for the wide

Automation and interconnections with information in their healthcare environments need increasing support, security measures need to be implemented without disrupting the workflow of approved users, costs associated with data breaches and damage to their reputation need to be avoided. IT budgets constraints also impose limitations in many healthcare institutions. Compliance with security and privacy related regulations in healthcare and making sure what policies and standards should be implemented requires solutions that clearly address security challenges so that they can be integrated into a healthcare institution’s existing infrastructure and business practice. As data is transmitted across countless environments and is stored on an ever-expanding grouping of endpoint and storage devices such as computers, laptops, and removable storage devices, it will become evident that there will be a need for strong encryption. Under the HITECH Act and comparable state laws, encrypted data that is received or acquired by unauthorized persons through a lost or stolen electronic device or an errant email, is typically not considered a breach. However, healthcare institutions need to determine the level of encryption they should adopt. For example, a hospital could decide where there is the greatest risk of information loss (patient data in email messages or on storage drive) that is not on internal

With the introduction of information technology advancement into the hospital health care system, we must embrace in this technology and must ensure that we have a more efficient and secure system. This will allow us to create measures that will allow us to protect electronic protected health information (ePHI). All data that is being transmitted on any open networks will be protected from any cyber attackers or unauthorized personnel. In order to protect this data, any ePHI data will be sent by encrypting the data to ensure that in the event that it is intercepted it

Assuming a large collections of files and documents and Data user in a external cloud environment. It permit the secure Multi-keyword search and it returns the relevant documents in a order to the search request. As shown in TABLE 3, here we compare the functionalities of cash’s scheme [10],Cao’s scheme [11] and Naveed’s scheme[13].

The electronic protected health information (ePHI) gets electronically stored and collected in hard copy form as they secure the information. According to the U.S. Department of health and Human Service Office for Civil Rights (OCR) report, millions of people have been impacted by HIPAA data breaches. Hence, healthcare organizations must protect and secure personal health data now more than ever because of the threats that are associated with information. This would substantially increase the protection of healthcare from cyber threats. Moreover, these people are extremely diverse and the cleverness of their data information must be organized within hospitals. Medical records are in high demand because of the sophistication of the records.

There’s two types used in encryption, there’s the public key which is used to encrypt the information you trying to send. There is also the private key which is used to decrypt the message. The public and private key is used in many things for example emails and telephones. The reason why it’s so important that these two keys are used is because the message you’re sending stays between you and the receiver, therefore the message will not get interrupted by an invader.

Before a health care organization implements an EMR system, they should have a security system in place, which includes “access control” component. Access control within an EMR system is controlled by distinct user roles and access levels, the enforcement of strong login passwords, severe user verification/authorization and user inactivity locks. Health care of professionals regardless of their level, each have specific permissions for accessing data. Even though the organization have the right security system in place to prevent unauthorized users from access patient records, autonomous patients will expect to have access to his or her records with ease. Access their record will ensure that their information is correct and safe.

I found the technique of the permuterm indexing especially of note. While it seems like it results in a massive index it was interesting to think of how that could be applied along with other ideas to mitigate human imperfections for searches.

Electronic Medical Records (EMR) is a computerized database that stores all of the personal and medical information of the patient’s care and billing information by the health care providers. Today, only the providers and medical practices can implement these systems. Also there are neither known national central storage systems nor regional sharing of information between the networks on a regional level or the national level. This is something that needs to be changed because it is important to be able to see this information globally. This

Only authorized personnel has access to the clinical data captured in medical records which include health care providers, insurers, government agencies, claims processors, and patients. Since the Electronic Medical Record (EMR) archives, disseminates, and analyzes health related information, the patient’s protected data includes demographic, financial, or any clinical data that might potentially identify the patient. To comply with HIPAA regulations, the medical record software used by outpatient clinics should include safety settings such as access logs, audit trails, password protection, and message encryption to avoid any intruder.

In a world full of electronics it would only seem logical to have health records electronic. Not only are medical records efficient, reliable, and quick to access, new technology allow patients to access their own personal medical records with a simple to use login and password. “People are asking whether any kind of electronic records can be made safe. If one is looking for a 100% privacy guarantee, the answer is no”(Thede, 2010). At my hospital, upon every admission we ask the patient for a password for friends and family to have to have if they would like an update on the patient 's condition. We do not let visitors come up and see the patient without the patient 's consent. In doing these things, we help to ensure the safety and protection of the patient 's health information and privacy.

While doing some of my research, I chose to use Computer Source as my database. The main subject of the database was trends in technology. It allowed me to search trends from any time which was particularly helpful for my topic. The type of search that can be completed using this database is Boolean searching. This type of searching style came in handy because the information I was searching for involved the cyber world, so it made it easier to differentiate which aspect of the cyber world I was researching. For example, differentiating between Cyber Terrorism and Terrorism or Cyber Warfare. Computer Source lets its users search by publication date rather than by scholarship level. Computer Source also showed similarities with Academic Search Complete in that they shared similar fields. But after conducting similar searches, Computer Source provided me with more relevant information. Overall, my search results were more refined and

In light of available security measures and their widespread acceptance within the information security community, there is no excuse for healthcare organizations to fail in fulfilling their duty to protect personal patient information. Guaranteeing the confidentiality and privacy of data in healthcare information is crucial in safeguarding the data of patients as there should be a legal responsibility to protect medical records from unauthorized access.
