Digital evidence integrality storage control system based on computer forensics

Abstract

The invention belongs to the technical field of data processing, and discloses a digital evidence integrality storage control system based on computer forensics. The system comprises: wireless sensor data collection nodes, a central data transmission node, a state signal module, a read-write control module and an operation module. Data read from a data memory are processed according to a signal transmitted by the read-write control module. The data collection nodes in the digital evidence integrality storage control system disclosed by the invention performs self organization to form a regional storage network, the data on each data collection node are stored in the nodes of the system in an encoding manner, and when the storage space of the ad hoc storage network is insufficient, the system covers the historical data with the newly collected data according to a certain interval through a set data coverage rule; and the digital evidence integrality storage control system disclosed by the invention greatly improves the reliability of the data storage of the system. The digital evidence integrality storage control system disclosed by the invention has popularization and application values.

Description

technical field [0001] The invention belongs to the technical field of data processing, in particular to a digital evidence integrity preservation control system based on computer forensics. Background technique [0002] In daily activities, for example, the user can use the calculator provided by the mobile terminal to perform relevant data calculations. However, the built-in calculator of the mobile terminal is a mode that requires the user to manually operate to realize the calculation, that is, after each manual input of a data, the user needs to manually select an operation symbol, and then manually input the next data, and so on. It can be seen from the above that the calculator in the normal mode has low efficiency and high error rate, and it is difficult to process a large amount of data. [0003] In the prior art, a method of preserving a digitally signed document (160) in a digital data preservation system (10). The secure deposit request (176) combines the docum...

AI Technical Summary

Problems solved by technology

[0007] To sum up, the problems existing in the existing technology are: due to factors such as large changes in the field environment and uncontrollable environment, the data acquisition nodes or remote wireless data transmission nodes in the wireless sensor system will be damaged, resulting in remote The data cannot be uploaded to the data server in time, or even the data is lost, so there is room for improvement; and the existing technology cannot be combined with the digital evidence for computer forensic integrity presentation; in the actual binary coding matrix construction process, it is all to meet the storage system The deletion-tolerance performance, regardless of whether it has the lowest calculation amount of the encoding process in the encoding process
