Referential SOA Architecture
Michal Maliarik
The article deals with referential SOA (Service-Oriented Architecture), its basic components and concepts. Through an example of the design and implementation of a new application, it also highlights certain advantages and differences compared to the conventional approach.

Detection of Viability
Martin Drahanský, Dana lodrová, Filip Orság, Eva Březinová
The article describes two newly patented methods for detecting the viability of biometric systems using fi nger-print scanning. The fi rst is based on the use of a camera with a macro-objective; the other assumes the use of a laser module to measure distance. Both use a special optical bench. The article focuses mainly on a side-by-side comparison of both methods. The text also mentions skin diseases that can prevent the recognition of an authorized user.

Healthy Ill E-passport
Luděk Rašek
The article describes incidents related to the security of e-passports that cast doubt on the security of the whole system of e-passports. The article analyzes all the incidents and their causes, and possible remedies for each problem.

Concealment of Data in File Systems
Roman Žilka
The article describes the concealment of data using steganographic file systems. It contains an explanation of functional principals that do not rely on a previous detailed knowledge of the organization. It proceeds iteratively from a clean disk and simple fi le system to a more complex stegosystem, for example TrueCrypt. The theory is supplemented by a practical description of plausible deniability of data stored in a similar security system.

Practical Diffi culties of PKI – Part II.
Daniel Kouřil, Michal Procházka
The article summarizes several years of experience with PKI implementation in a large distributed environment, a so-called grid. A number of problems that are discussed in the article are not apparent in smaller systems. They only express themselves only when the complexity of the infrastructure exceeds a certain level.
