Peter Gutmann (computer Scientist)
Peter Claus Gutmann is a computer scientist in the Department of Computer Science at the University of Auckland, Auckland, New Zealand. He has a Ph.D. in computer science from the University of Auckland. His Ph.D. thesis titled and a book based on the thesis were about a cryptographic security architecture. He is interested in computer security issues, including security architecture, security usability (or more usually the lack thereof), and hardware security; he has discovered several flaws in publicly released cryptosystems and protocols. He is the developer of the cryptlib open source software security library and contributed to PGP version 2. In 1994 he developed the Secure FileSystem (SFS). He is also known for his analysis of data deletion on electronic memory media, magnetic and otherwise, and devised the Gutmann method for erasing data from a hard drive more or less securely. Having lived in New Zealand for some time, he has written on such subjects as weta (a group of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gutmann Method
The Gutmann method is an algorithm for securely erasing the contents of computer hard disk drives, such as files. Devised by Peter Gutmann and Colin Plumb and presented in the paper ''Secure Deletion of Data from Magnetic and Solid-State Memory'' in July 1996, it involved writing a series of 35 patterns over the region to be erased. The selection of patterns assumes that the user does not know the encoding mechanism used by the drive, so it includes patterns designed specifically for three types of drives. A user who knows which type of encoding the drive uses can choose only those patterns intended for their drive. A drive with a different encoding mechanism would need different patterns. Most of the patterns in the Gutmann method were designed for older MFM/ RLL encoded disks. Gutmann himself has noted that more modern drives no longer use these older encoding techniques, making parts of the method irrelevant. He said "In the time since this paper was published, some people ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Privacy
Information privacy is the relationship between the collection and dissemination of data, technology, the public expectation of privacy, contextual information norms, and the legal and political issues surrounding them. It is also known as data privacy or data protection. Data privacy is challenging since attempts to use data while protecting an individual's privacy preferences and personally identifiable information. The fields of computer security, data security, and information security all design and use software, hardware, and human resources to address this issue. Authorities Laws Authorities by country Information types Various types of personal information often come under privacy concerns. Cable television This describes the ability to control what information one reveals about oneself over cable television, and who can access that information. For example, third parties can track IP TV programs someone has watched at any given time. "The addition of any informati ...

Criticism Of Windows Vista
Windows Vista, an operating system released by Microsoft for consumers on January 30, 2007, has been widely criticized by reviewers and users. Due to issues with new security features, performance, driver support and product activation, Windows Vista has been the subject of a number of negative assessments by various groups. Security Driver signing requirement For security reasons, 64-bit versions of Windows Vista allow only signed drivers to be installed in kernel mode. Because code executing in kernel mode enjoys wide privileges on the system, the signing requirement aims to ensure that only code with a known origin executes at this level. In order for a driver to be signed, a developer/software vendor has to obtain an Authenticode certificate with which to sign the driver. Authenticode certificates can be obtained from certificate authorities trusted by Microsoft. Microsoft trusts the certificate authority to verify the applicant's identity before issuing a certificate. If a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Longest Suicide Note In History
"The longest suicide note in history" is an epithet originally used by United Kingdom Labour MP Gerald Kaufman to describe his party's 1983 general election manifesto, which emphasised socialist policies in a more profound manner than previous such documents—and which Kaufman felt would ensure that the Labour Party (then in opposition) would fail to win the election. Document ''The New Hope for Britain'' was a 39-page booklet which called for unilateral nuclear disarmament; higher personal taxation for the rich; withdrawal from the European Economic Community; abolition of the House of Lords; and the re-nationalisation of recently privatised industries such as British Aerospace and the British Shipbuilders Corporation. The manifesto was based on an earlier and much longer policy paper with a similar title, ''Labour's Plan: the New Hope for Britain''. The epithet referred not only to the orientation of the policies, but also to their marketing. Labour leader Michael Foot d ...

White Paper
A white paper is a report or guide that informs readers concisely about a complex issue and presents the issuing body's philosophy on the matter. It is meant to help readers understand an issue, solve a problem, or make a decision. A white paper is the first document researchers should read to better understand a core concept or idea. The term originated in the 1920s to mean a type of position paper or industry report published by some department of the UK government. Since the 1990s, this type of document has proliferated in business. Today, a business-to-business (B2B) white paper is closer to a marketing presentation, a form of content meant to persuade customers and partners and promote a certain product or viewpoint. That makes B2B white papers a type of grey literature. In government The term ''white paper'' originated with the British government and many point to the Churchill White Paper of 1922 as the earliest well-known example under this name.
