Abstract

Certificate of public security electronic case information construction of public security police after iconic product of ten years of development, is also a valuable resource for Police Practice the accumulation and reality struggle to play in many aspects of today's public security work, intelligence, surveillance detection, and judicial proceedings important force of law and conclusions role. Under the new situation, accompanied by information security system are maturing, social and legal process continues to accelerate, the public security organs is to create electronic case permits regularization procedures and the rule of law, but also actively expanding the use of electronic case permits and use of the field, so that evidence of weapons can be for the whole of the political and legal system in the struggle against the enemy. Therefore, in practice, the public security organs is bound to stronger efforts to larger, more skills to deal with and solve the problem of the lawful use of data sharing and security, preservation of electronic case card. Subject to the fingerprint authentication and cryptography technology as the basis, the organic integration of the two technologies in the real demand is proposed to construct economical and practical, security, seamlessly connecting with the public security police information technology based on fingerprint identity certification of public security electronic case permit police system. The main tasks in the system design and implementation include: 1, the use of fingerprint recognition technology, positioning fingerprint center point for the live fingerprint image in the pretreatment to the value of the feature extraction and matching, thus enhancing the compactness of feature extraction and to improve the fingerprint matching rate of the entire local public security organs have legal status and privileges of Police uniform identity authentication, sharing platform for electronic case permit police system as well as other public security business application systems to build an information security. 2, application of the basic principles of the field of cryptography and many algorithms, symmetric and asymmetric encryption and decryption technology of the electronic case certificates encrypt fixed with safety preservation; using the SHA-256 hashing algorithm to calculate and validate electronic case card packet digital Abstract and realized submit electronic case provably secure signature based on public key infrastructure (PKI). Summarized from the Criminal Law, Criminal Procedure Law and other legal aspects of the composition in the form of the definition of public security case card case certified electronic achieved through technical means, combined with the business needs of public security work on the electronic case permits, operation mechanism and use, planning and draft global framework for electronic case permit police system. Reasonable software engineering development for the overall design of the system, subsystem completes the overall implementation of the system through the integrated security and communication interface components, electronic case card fixed subsystem, electronic case certificates submitted. On the basis of system integration and testing, access and analysis of operating parameters and results, suggest improvements and outlook, provide a good solution for the real demand. 5, the system always dominant design information security, achieve specific process highlights reflect the electronic case card fixed with the submission of the security policy, authorization management, content protection and access control to ensure the confidentiality of the electronic case card application, real , integrity, and availability. System put into practice run for public security electronic case card operations to establish a reliable security barrier, and also provides a secure storage space for electronic case card data preservation surly protect public security electronic case certified information security and standardized utilization. At the same time, the system highlights the public security organs to the electronic case card legalization and integration of information technology to enhance electronic case permit in the field of political and legal system to maximize efficiency.
