During a research project, the project members are usually responsible for the usability and storage of the data. Archiving typically occurs after the project has ended, and the responsibility for storing the data is assumed by a research organisation, a university, or a unit specialising in the archiving of data, such as the Finnish Social Science Data Archive FSD.

Here, the two dimensions of data sharing building blocks and data security aspects are combined. For each data sharing building block, we show which security aspects are applicable and we present a list of security recommendations based on these aspects. The controls specify the practical measures that should be considered for implementing the stated recommendations. The appropriate measures can be technical, physical, procedural, or policy-specific.

Data erasure

Metrics details. To provide confidentiality guarantee, the data should be protected when they are preserved in the personal computing devices i. Encryption and secure deletion are used to ensure data confidentiality during and after their lifetime, respectively. This work aims to perform a thorough literature review on the techniques being used to protect confidentiality of the data in personal computing devices, including both encryption and secure deletion. Especially for encryption, we mainly focus on the novel plausibly deniable encryption PDE , which can ensure data confidentiality against both a coercive i.

Data erasure sometimes referred to as data clearing , data wiping , or data destruction is a software-based method of overwriting the data that aims to completely destroy all electronic data residing on a hard disk drive or other digital media by using zeros and ones to overwrite data onto all sectors of the device. By overwriting the data on the storage device, the data is rendered unrecoverable and achieves data sanitization. Permanent data erasure goes beyond basic file deletion commands, which only remove direct pointers to the data disk sectors and make the data recovery possible with common software tools. Unlike degaussing and physical destruction, which render the storage media unusable, data erasure removes all information while leaving the disk operable. New flash memory -based media implementations, such as solid-state drives or USB flash drives , can cause data erasure techniques to fail allowing remnant data to be recoverable. Software-based overwriting uses a software application to write a stream of zeros, ones or meaningless pseudorandom data onto all sectors of a hard disk drive.

As the amount of digital data grows, so does the theft of sensitive data through the loss or misplacement of laptops, thumb drives, external hard drives, and other electronic storage media. Sensitive data may also be leaked accidentally due to improper disposal or resale of storage media.

A survey of confidential data storage and deletion methods

Your research data are valuable assets to you, and potentially to the wider research community, and you have probably invested considerable time, effort and money in creating them. To protect your data you need to consider how they are stored, backed-up and secured whilst still working on them. You should consider the following:. An additional 1TB is available for second and subsequent funded projects. The University's research storage service is resilient, with multiple copies stored in more than one physical location and measures to protect against corruption.

Working with data: Data storage

With the decrease in cost of electronic storage media, more and more sensitive data gets stored in those media. Laptop computers regularly go missing, either because they are lost or because they are stolen. These laptops contain confidential information, in the form of documents, presentations, emails, cached data, and network access credentials. This confidential information is typically far more valuable than the laptop hardware, if it reaches right people.

Надо выбираться из шифровалки. Черт с ней, с Цифровой крепостью. Пришла пора действовать.

Та показала ему последние строчки текста. Бринкерхофф читал, не веря своим глазам. - Какого чер… В распечатке был список последних тридцати шести файлов, введенных в ТРАНСТЕКСТ.

Мы обнаружили статистический сбой и хотим выяснить, в чем. Кроме того, - добавила она, - я хотела бы напомнить Стратмору, что Большой Брат не спускает с него глаз. Пусть хорошенько подумает, прежде чем затевать очередную авантюру с целью спасения мира.  - Она подняла телефонную трубку и начала набирать номер. Бринкерхофф сидел как на иголках.

Коммандер обогнул ТРАНСТЕКСТ и, приблизившись к люку, заглянул в бурлящую, окутанную паром бездну. Молча обернулся, бросил взгляд на погруженную во тьму шифровалку и, нагнувшись приподнял тяжелую крышку люка. Она описала дугу и, когда он отпустил руку, с грохотом закрыла люк. Шифровалка снова превратилась в затихшую черную пещеру. Скорее всего Северная Дакота попал в ловушку.

Как весенний лед на реке, потрескивал корпус ТРАНСТЕКСТА. - Я спущусь вниз и отключу электропитание, - сказал Стратмор, положив руку на плечо Сьюзан и стараясь ее успокоить.  - И сразу же вернусь.

 Некоторые идеи о протоколах вариативных фильтров и квадратичных остатках. - Стопроцентный бестселлер. Она засмеялась.

Любовь и честь были забыты. Мечта, которой он жил все эти годы, умерла. Он никогда не получит Сьюзан Флетчер. Никогда.

Беккер узнал голос. Это девушка.

Thus, the strength of the confidentiality of the data storage or deletion is based directly upon the technique used to store or delete the data at rest (for example, the.
