The traceability management system of aquatic product is based on RFID techniques which could obtain the function of aquatic products statistics and water quality monitoring automatically. The system frame, hardware and software design of micro-controller and anti-collision algorithm are issued in this paper. The identifying of aquatic product and water quality monitoring information are delivered to the management system and the speed of reading operation is increased greatly.

The article is devoted to the development of the concept of the state to manage its tax risks, based on a systematic approach. The author's concept presupposes the presence of the following elements logically arranged according to the principle "from the general to the particular": 1) mechanisms for managing tax risks, 2) disclosing methodological recommendations, 3) specific proposals for changing legislation. To achieve this goal, the author used general scientific methods (deduction and induction, analysis and synthesis, observation, description, generalization) and private scientific methods of cognition (comparison method, graphical and tabular data presentation methods). We have presented a brief overview of the main tax risks of the Russian Federation in the current economic environment, which are classified in four areas: 1) risks in the field of value added taxation; 2) risks in the field of taxation of profits and income; 3) risks, the source of which is Russia's membership in the Eurasian Economic Union; 4) customs risks. The author presents a general scheme of tax risk management by the state, which includes the context, goals and management strategy. The priority mechanisms for managing the tax risks of the state are formulated on the basis of the presented classification of tax risks. These areas include: introduction of an end-to-end product traceability system; substantiation of taxation methods; joint elimination of tax risks (Federal Tax Service, Federal Customs Service, Ministry of Labor, Federal Service for Financial Monitoring); optimization of tax administration costs on the part of both tax authorities and taxpayers; harmonization of indirect taxation, including duty-free trade; harmonization of international tax rules at the international level; selection of the most effective tools for eliminating multiple taxation. A draft "road map" has been developed to improve the management of state tax risks.

Traceability is considered a promising solution for product safety. However, the data in the traceability system is only a claim rather than a fact. Therefore, the quality and safety of the product cannot be guaranteed since we cannot ensure the authenticity of products (aka counterfeit detection) in the real world. In this paper, we focus on counterfeit detection for the traceability system. The risk of counterfeiting throughout a typical product life cycle in the supply chain is analyzed, and the corresponding requirements for the tags, packages, and traceability system are given to eliminate these risks. Based on the analysis, an anti-counterfeiting architecture for traceability system based on two-level quick response codes (2LQR codes) is proposed, where the problem of counterfeit detection for a product is transformed into the problem of copy detection for the 2LQR code tag. According to the characteristics of the traceability system, the generation progress of the 2LQR code is modified, and there is a corresponding improved algorithm to estimate the actual location of patterns in the scanned image of the modified 2LQR code tag to improve the performance of copy detection. A prototype system based on the proposed architecture is implemented, where the consumers can perform traceability information queries by scanning the 2LQR code on the product package with any QR code reader. They can also scan the 2LQR code with a home-scanner or office-scanner, and send the scanned image to the system to perform counterfeit detection. Compared with other anti-counterfeiting solutions, the proposed architecture has advantages of low cost, generality, and good performance. Therefore, it is a promising solution to replace the existing anti-counterfeiting system.
