Embodiment 1
[0049] Such as figure 1 As shown, this embodiment provides an electronic evidence collection management method, the electronic evidence collection management method includes:
[0050] S101. Calculate the stored electronic forensics data according to a preset digest algorithm to obtain a message digest;
[0051] S102. Write the credible time stamp, electronic device address, basic vehicle information and message summary as evidence records into the latest node of the blockchain; the latest node of the blockchain is used to package the evidence records and then broadcast and synchronize them to the blockchain other electronic forensics equipment.
[0052]In this embodiment, the message digest is calculated for the stored electronic forensics data according to the preset digest algorithm, and then the trusted time stamp, electronic device address, basic vehicle information and message digest are uploaded as evidence records, without the need to upload the original text of the el...
Embodiment 2
[0070] For convenience, this embodiment uses a more specific example to illustrate the electronic forensics management method, such as image 3 As shown, the electronic forensics management method includes:
[0071] S301. An electronic forensics device collects and saves the electronic forensics data of the vehicle.
[0072] S302. An electronic forensics device uses the SM3 algorithm to calculate the electronic forensics data, and generates a message digest.
[0073] The electronic forensics data includes vehicle videos, pictures, and txt texts of vehicle information records, and the SM3 algorithm is uniformly used. Through this algorithm, each file obtains a 32-bit fixed-length message summary. The vehicle video includes the video of the vehicle running, and the vehicle information record txt text includes the overload state of the vehicle, the information of the passing road section and the speed information of the vehicle, etc.
[0074] S303. An electronic forensics devic...
Embodiment 3
[0089] This embodiment provides an electronic evidence collection device, such as Figure 4 As shown, the electronic evidence collection device includes a processor 41, a memory 42 and a communication bus 43;
[0090] The communication bus 43 is used to realize connection and communication between the processor 41 and the memory 42;
[0091] The processor 41 is configured to execute one or more computer programs stored in the memory, so as to realize the above steps of the following electronic forensics management method:
[0092] Calculate the stored electronic forensics data according to the preset digest algorithm to obtain the message digest;
[0093] Write trusted timestamps, electronic device addresses, basic vehicle information, and message summaries as evidence records to the latest node of the blockchain; the latest node of the blockchain is used to package the evidence records and broadcast them to other blockchain nodes Electronic forensics device node.
