step four: detecting the four properties of the electronic file and the electronic archive, wherein the serial number after detecting the project is the called interface serial number;
the electronic file and the method for detecting the four properties of the electronic file specifically comprise the following contents:
firstly, performing environment detection;
secondly, after the environment detection is completed, entering information package and database metadata detection, and simultaneously carrying out detection work of availability, authenticity, integrity and safety, wherein the specific detection method comprises the following steps:
1) Firstly, detecting accessibility of metadata in a target database and readability of metadata in an information packet, and detecting whether the database and the information packet are communicated or not so as to further go deep into a subsequent data detection link;
2) After the database connection and the readable information package are determined, consistency detection of the information package is performed, so that the information package is ensured not to be tampered;
3) Aiming at the information package, the information package directory structure normalization detection and the specification file and directory file normalization detection are carried out, so that the structure accuracy of the information package is ensured, and the information package is convenient for further utilization;
4) Analyzing the information package to obtain an electronic file package, and detecting the normalization of the electronic file package to ensure the compliance of the electronic file package structure in the information package, thereby facilitating further utilization;
5) And aiming at the electronic file package after the verification in the last step, carrying out XML code-level verification: detecting the validity of an electronic signature of an electronic file package, and ensuring that the complete source of XML codes is feasible by analyzing the validity of the electronic signature in the package;
6) The next step of deep analysis detection of the information packet is performed, firstly, the comparison of the number of files is performed, the consistency of the total number of files is detected, the integrity of the content data of the information packet is detected, the redundant files in the carrier are detected, and then the comparison of the storage size of the files is performed, and the consistency of the total number of bytes is detected;
7) Next, comparing the metadata items, analyzing the accuracy of the metadata items, and sequentially performing metadata item integrity check and information package metadata integrity check;
8) Next, analyzing metadata content, namely firstly starting to detect from the content format of a file number, and detecting the normalization of the file number and the consistency of metadata items and requirements of an archive;
9) After the file number analysis is completed, further expanding to detect metadata attributes of the electronic file, and detecting consistency of electronic attributes of the content data;
10 Further detecting whether metadata is associated with content data, analyzing whether the file path pointed by each metadata has associated content, and detecting the archiving range;
11 Continuing to detect the format and content aspects of other metadata item contents, including metadata item data length detection, metadata item data type, format detection, metadata item value range coincidence detection of a set value range, metadata item data value rationality detection, metadata item data containing special character detection, metadata item data repeatability detection, metadata item filling detection, process information integrity detection and continuity metadata item detection;
thirdly, detecting the content of the electronic file;
and fourthly, comprehensively judging all the processes in the process to finish the safety detection of the operation process.
2. The method for detecting the four-property of the electronic file and the electronic archive of the service-oriented construction project according to claim 1, wherein the method comprises the following steps: in the fourth step, in the method for detecting the four properties of the electronic file and the electronic archive, when the detection item fails, all detection results are recorded and displayed to the user together.
3. The method for detecting the four-property of the electronic file and the electronic archive of the service-oriented construction project according to claim 2, wherein the method comprises the following steps: in the fourth step, the specific method for performing the environment detection is as follows:
1) Simultaneously starting availability detection and security detection by adopting a multithreading operation mode;
2) The method comprises the steps of sequentially detecting the change condition of a storage environment, detecting the restorability of backup data and detecting the compliance of software and hardware environments in the usability detection;
3) At the same time of the detection in the previous step, the system simultaneously carries out detection on whether antivirus software is installed in the system environment, virus infection detection, carrier reading speed detection, carrier appearance detection, CD qualification detection, software system security hole detection and carrier storage environment security detection in the security detection unit.
4. The method for detecting the four-property of the electronic file and the electronic archive of the service-oriented construction project according to claim 3, wherein the method comprises the following steps: in the fourth step, the specific method for detecting the content of the electronic file is as follows:
1) After the detection of all metadata items and the content formats thereof is finished in the last step, the electronic files associated with the metadata are deeply detected one by one, and the validity detection of the solidification information is finished first, so that each electronic file is ensured not to be tampered;
2) Next, content data format detection, content data readability detection, content data integrity detection, content data format long-term availability detection, attachment data integrity detection, content data format compliance detection contained in the information package are performed.
