Měření efektivnosti zavedení datových schránek / Measuring the effectiveness of the introduction of data boxes

Ovesný, Tomáš January 2009 (has links)
This work addresses the issue of data boxes information system, which supports electronic communication between public authorities and other bodies. Aim of the work is to identify measure and evaluate the effectiveness of the data boxes at selected public authorities when processing received and sent documents. The effectiveness is detected by using the proposed metrics and also based on the analysis conducted in order to examine the processing of documents at selected institutions. The effectiveness of data boxes is being researched at the Municipal Office Dub nad Moravou and the Czech Agriculture and Food Inspection Authority. The information needed for the process analysis and the data required for evaluating the effectiveness of the implementation of the proposed metrics were obtained from the staff of those institutions. The work is divided into four parts. The first part is a thorough description of the data boxes information system. The functionality, use, technical solutions and legislations of data boxes are described based on available information. The second part focuses on the description and analysis of selected public authorities and on the way they process received and outgoing mail. In the third part of the work appropriate metrics to assess the effectiveness of the data boxes are proposed, followed by implementation of two-phase measurements. In the fourth section the effectiveness of the data boxes is evaluated based on the measurements conducted at selected public authorities. The main contribution of this work is that it will be the first evaluation of the effectiveness of the data boxes in selected subjects approximately one month after the official launch. Another benefit is the proposal of process for the evaluation of the effectiveness of a very specific new information system within the body and a comprehensive description of the data boxes information system.

Možnosti měření efektivnosti systému financování a poskytování sociálních služeb / Possibilities of estimating the efficiency of financial system and granting social services

Jeřábková, Věra January 2011 (has links)
A significant problem of functioning the public sector is to ensure the efficiency of public expenditures. Efficiency model's creating is a dynamic process that requires regular evaluation of the socioeconomic conditions. The efficiency of financial system and granting social services is still not measured in the Czech Republic. The area of social services is affected by number of criteria and factors. So it is necessary to apply different views on evaluating the efficiency of social care, social prevention and social counseling. The efficiency of social services can not be estimated as a whole, but we should focus on different groups of social services and individual services within the group. In this thesis the efficiency is measured in the two selected residental social care services -- homes for the elderly and homes for people with disabilities. The applied methods was used only to a limited extent because of lacks of many important variables in the area of official statics. In the case of multiple criteria methods the calculation was also impeded by the availability of suitable software.

Korelace dat na vstupu a výstupu sítě Tor / Correlation of Inbound and Outbound Traffic of Tor Network

Coufal, Zdeněk January 2014 (has links)
Communication in public networks based on the IP protocol is not really anonymous because it is possible to determine the source and destination IP address of each packet. Users who want to be anonymous are forced to use anonymization networks, such as Tor. In case such a user is target of lawful interception, it presents a problem for those systems because they only see that the user communicated with anonymization network and have a suspicion that the data stream at the output of anonymization network belong to the same user. The aim of this master thesis was to design a correlation method to determine the dependence of the data stream at the input and the output of the Tor network. The proposed method analysis network traffic and compares characteristics of data streams extracted from metadata, such as time of occurence and the size of packets. This method specializes in correlating data flows of protocol HTTP, specifically web server responses. It was tested on real data from the Tor network and successfully recognized dependency of data flows.

Dopady ISDS na uživatele / The Impact of the ISDS on Users

Řehořek, Tomáš January 2013 (has links)
This thesis work is to do with the Information system of data boxes (ISDS) which is introduced from legislation's and user's point of view. Because the introduction of this system has influenced hundreds of thousands of subjects the main target of this thesis is to find out about the impact of the ISDS on users with the help of the analysis method. In this work firstly the data provided by the Ministry of Internal Affairs are examined and interpreted, secondly the results of the poll conducted by the author and then a cost-benefit analysis of the system from the users' point of view is carried out. The results of the work show that the ISDS was at the end of the examined period (2009 -- 2013) beneficial for its users and the total economic benefit for the respective period is 3.6 billion Czech crowns. This means that every crown spent on the operation of the system by the Ministry of Internal Affairs represents savings of 2 Czech crowns. The author of this work has come to the conclusion that the system is from a legislative, technological and economic point of view very well created. The author recommends to the system administrator its further development and also recommends to use its potential among thousands of OSVČ (the self-employed).
