Description

Method for storing electronic signature by electronic evidence

Technical Field

The invention relates to a method for storing an electronic signature by using electronic evidence, and belongs to the technical field of computers.

Background

Many related departments are equipped with multifunctional integrated acquisition equipment, the equipment is provided with high-definition cameras, microphones, bluetooth, wi-Fi, 4G/5G and other functional modules, all on-site investigation data can be completed by one piece of equipment, and the equipment is connected with an evidence server in a data line or wireless mode and then performs data uploading operation. Each time a new case file is created, all electronic evidence is contained in the file record, and compliance and traceability of the electronic evidence in the case electronic file are ensured by means of adding a handwriting signature to a traditional paper list. The above handwritten signature process is very important for legal procedures, which is often the focus of appeal parties in court disputes, and many cases are excluded from the evidence list because of evidence collection and storage non-compliance. Paper list and hand-written signature have high artificial error rate due to the factors of complicated process, difficult preservation and the like.

Disclosure of Invention

The invention aims to overcome the defects in the prior art, and provides an electronic evidence storage electronic signature method, which is used for automatically initiating an electronic signature request for record metadata of a case file after an acquisition device uploads electronic evidence to an evidence server, and related personnel complete electronic signature after identity authentication is completed on the acquisition device with biological identification. The invention uses the electronic signature to replace the paper signature process stored in the electronic evidence file, thereby improving the file transfer efficiency and reducing the possibility of human error.

The electronic evidence storage electronic signature method requires that the evidence acquisition equipment 1 is provided with hardware modules such as a network 101, a biological identification 102, a safe storage area 103 and the like, and the evidence server 2 is provided with hardware modules such as a network 201, a database 202 and the like.

The evidence collection device 1 has a unique number device_id, identity binding is carried out on a relevant person (police _id) before an electronic evidence collection task is executed, the biological characteristics (fingerprint or face) of the relevant person are recorded in the biological recognition module 102 of the collection device, the private key of the relevant person is stored in the safe storage area 103 of the evidence collection device 1, and the evidence server 2 only stores the identity information and public key of the relevant person and does not store the biological characteristics of the relevant person.

The method comprises the following steps:

Step 1, before a related person starts investigation on site, creating a case file in an evidence collection device 1, and storing all electronic evidence (photos, audios and videos) collected by the evidence collection device 1 in the file;

Step 2, after the present investigation is finished, uploading the electronic evidence in the evidence acquisition equipment 1 to the evidence server 2 through a network in a related institution;

Step 3, the evidence server 2 creates a case archive metadata record case_metadata in the database 202, and the case id number is used as a main key;

step 4, the evidence server 2 sends the case_metadata to the evidence acquisition equipment 1 in a JSON format, and sends an electronic signature request;

And 5, after receiving the electronic signature request, the evidence collection device 1 sends a biological characteristic identification request to related personnel, if the request passes, a private key is extracted from the secure storage area 103, and the electronic signature 3 is carried out on the case_metadata by using a signature algorithm, and signature data is filled into creator _signature fields of the case_metadata and stored as the case_metadata' (4). If the biological characteristic identification does not pass, rejecting the signature request;

Step 6, the evidence collection device 1 transmits the case_metadata' back to the evidence server 2;

Step 7, the evidence server 2 uses the public key of the related personnel to verify the electronic signature in the case_metadata', if the electronic signature passes, the electronic signature is stored in the database 202, and otherwise, error information is returned.

The beneficial effects are that:

According to the invention, the electronic signature request can be automatically initiated on the record metadata of the case file after the acquisition equipment uploads the electronic evidence to the evidence server, and the related personnel complete the electronic signature after the identity authentication on the acquisition equipment with the biological identification. The invention uses the electronic signature to replace the paper signature process stored in the electronic evidence file, thereby improving the file transfer efficiency and reducing the possibility of human error.

Detailed Description

The invention will be described in further detail with reference to the drawings.

As shown in fig. 1, the invention provides an electronic evidence storage electronic signature method, which automatically initiates an electronic signature request to record metadata of a case file after an acquisition device uploads electronic evidence to an evidence server, and related personnel completes electronic signature after identity authentication is completed on the acquisition device with biological recognition. The invention uses the electronic signature to replace the paper signature process stored in the electronic evidence file, thereby improving the file transfer efficiency and reducing the possibility of human error.

The invention is characterized in that the collecting device is provided with a unique number device_id, the device is already subjected to identity binding with a relevant person (police _id) before an electronic evidence collecting task is executed, the biological characteristics (fingerprint or face) of the relevant person are recorded in a biological identification module 102 of the collecting device, the private key of the relevant person is stored in a safe storage area 103 of the evidence collecting device 1, and the evidence server 2 only stores the identity information and public key of the relevant person and does not store the biological characteristics of the relevant person.

The method comprises the following steps:

Step 4, the evidence server 2 sends the case_metadata to the evidence collection device 1 in a JSON format (shown in figure 2) to send out an electronic signature request;

And 5, after receiving the electronic signature request, the evidence collection device 1 sends a biological characteristic identification request to related personnel, if the request passes, a private key is extracted from the secure storage area 103, and the electronic signature 3 is carried out on the case_metadata by using a signature algorithm, and signature data is filled into creator _signature fields of the case_metadata and stored as the case_metadata' (4). Rejecting the signature request if the biometric identification does not pass (as shown in fig. 3);

The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention.
