Content available Determining signatures' characteristic features using statistical methods
Para T., Mitas M.
Journal of Medical Informatics & Technologies

Vol. 12
41--49
EN
Many signatures verification systems have been developed so far. Most of them have some common algorithms and solutions. The problem is that authors of the solutions usually present the final results of a working system. They do not reveal effects of the particular components. This is why other researchers do not know which element improves the results and is worth using. This paper shows how to estimate, in an easy way, if the selected component/set of data/feature gives good results.

Nowadays, automatic signature verification is an active area of researches in numerous applications such as bank check verification, access restriction or special areas such as police investigations. In our researches signature was captured by Topaz SigLite T-LBK750-HSB device, where some dynamic features of signature can be also registered. In many transactions, the electronic verification of a person's identity is beneficial, hence it inspires the development of a wide range of automatic identification systems. In this paper the system that automatically authenticates documents based on the owner's handwritten signature is presented.

In this paper the off-line type signature analysis have been presented. The signature recognition is composed of some features. Different influences of such features were tested and stated. Proposed approach gives good signature recognition level, hence described method can be used in many areas, for example in biometric authentication, as biometric computer protection or as method of the analysis of person's behaviour changes.

The learning process by Internet needs various interfaces used for current knowledge analysis. The elaborated unit allows the user to make a simple check-up of his present qualifications. That is useful for indicating the adequate resources, the most suitable for his next learning process, within the Internet Distance Learning University. This interface can provide the user with a static information data and dynamic sequences of the e-content, as well.

Vol. 9
323--335
EN
The e-content development methods are the most important task that has to be solved for electronic lessons implementation. The second important work that has to be done concerns data files distribution for eligible users of an Internet education resources database. These demanding solutions are integrating different levels and different technologies of programming. The paper describes several aspects of an Internet e-content databases structure and services needed for their content distribution, using high level Internet resources protection standards.
