This paper discusses the use of wavelets for the preprocessing of data from seismic observation stations. The authors analyze the application of wavelets for seismic event data processing, discuss natural disasters prediction trends and make a decision about importance of performing additional seismic data analysis. We provide a new approach of sei...

These days web resources keep and process a lot of valuable information. Confidential data and private pages have to be protected due to business processes. To implement this requirement and limit the number of people having access to the restricted resources, you need to configure a proper authentication on website. Unfortunately authentication is...

The reason of this fact is a rather high reliability of existing algorithms. In terms of information security, we can distinguish the following important tasks: ensuring the availability of information, its authenticity a...

The article deals with a study of web-crawler behaviour on different websites. A classification of web-robots, information gathering tools and their detection methods are provided. Well-known scrapers and their behaviour are analyzed on the base of large web-server log set. Experimental results demonstrate that web-robot can be distinguished from h...
