RFID with Bio-Smart Card in Linux - In this paper, we describe the integration of fingerprint template and RF smart card for clustered network, which is designed on Linux platform and Open source technology to obtain biometrics security. Combination of smart card and biometrics has achieved in two step authentication where smart card authentication is based on a Personal Identification Number (PIN) and the card holder is authenticated using the biometrics template stored in the smart card that is based on the fingerprint verification. The fingerprint verification has to be executed on central host server for security purposes. Protocol designed allows controlling entire parameters of smart security controller like PIN options, Reader delay, real-time clock, alarm option and cardholder access conditions.
pgp Key Signing Observations: Overlooked Social and Technical Considerations - While there are several sources of technical information on using pgp in general, and key signing in particular, this article emphasizes social aspects of key signing that are too often ignored, misleading or incorrect in the technical literature. There are also technical issues pointed out where I believe other documentation to be lacking. It is important to acknowledge and address social aspects in a system such as pgp, because the weakest link in the system is the human that is using it. The algorithms, protocols and applications used as part of a pgp system are relatively difficult to compromise or 'break', but the human user can often be easily fooled. Since the human is the weak link in this chain, attention must be paid to actions and decisions of that human; users must be aware of the pitfalls and know how to avoid them.

| Common Security Solutions Can't Prevent Data Theft | ||
11th, November, 2006
Widely used data security solutions have been found useless against several methods of data theft, according to tests conducted by a data security Innersafe Corporation. Types of data exposed included those useful for fraud, identity theft, phishing, or spamming. And, like tampered votes in certain electronic voting machines, data theft can remain undetected after it happens. |

There you are, happily playing around with an audio file you've spent all afternoon tweaking, and you're thinking, "Wow, doesn't it sound great? Lemme just move it over here." At that point your subconscious chimes in, "Um, you meant mv, not rm, right?" Oops. I feel your pain -- this happens to everyone. But there's a straightforward method to recover your lost file, and since it works on every standard Linux system, everyone ought to know how to do it. Briefly, a file as it appears somewhere on a Linux filesystem is actually just a link to an inode, which contains all of the file's properties, such as permissions and ownership, as well as the addresses of the data blocks where the file's content is stored on disk. When you rm a file, you're removing the link that points to its inode, but not the inode itself; other processes (such as your audio player) might still have it open. It's only after they're through and all links are removed that an inode and the data blocks it pointed to are made available for writing. |

With security on the Internet, there's always some nagging doubt. Can you ever be absolutely certain, for example, that the e-mail you're sending with some confidential business information attached isn't going to be intercepted and read as it travels the digital highways and byways? Using the Internet for anything sensitive requires some faith that everything in place to ensure the security of the information you're working with | ||
